Acanthophysium aberrans (G. Cunn.) G. Cunn. 1963
CONIFERAE. Pinus radiata: Nelson, Appleby, 30 m. CORIARIACEAE. Coriaria arborea: Auckland, Te Puna, coast. MYRTACEAE. Leptospermum ericoides: Auckland, Te Moehau, Coromandel Peninsula, 250 m. Wellington, Oturere River, Mt. Tongariro, 1,200 m. Leptospermum scoparium: Auckland, Mt. Te Aroha, 400 m, type collection, P.D.D. herbarium, No. 15238; Monument, Huia, 70 m. Wellington, Kaimanawa Ranges, 800-1,200 m.
Hymenophore annual, adherent, ceraceous-cretaceous, at first appearing as small linear scattered colonies 2-5 x 1-2 cm, becoming coalesced forming linear effused areas to 5 cm long; hymenial surface white, remaining so or becoming cream, or occasionally sulphur-yellow, at length deeply areolately creviced; margin thinning out, fibrillose, white, adherent. Context white, 120-160 µ thick, basal layer narrow, of mainly parallel hyphae, intermediate layer occupying the greater part of the context, of closely arranged erect hyphae soon cemented by their walls to form a pseudoparenchyma, embedding masses of crystals; generative hyphae forming the bulk of the hymenial layer, clavate or fusiform, to 6 µ, diameter, with the apical region covered with several (5-14) blunt processes 2-3 µ long. Gloeocystidia arising in the base of the context and subhymenium, some projecting slightly, fusiform or flexuous-cylindrical, 45-80 x 8-10 µ, apices rounded. Hymenial layer to 50 µ deep, a loose palisade of basidia, paraphyses, acanthophyses, and gloeocystidia. Basidia subclavate, 16-25 x 5-6 µ, bearing 4 spores; sterigmata slender, erect, to 6 µ long. Paraphyses subclavate, scanty, 12-18 x 4-5 µ. Spores elliptic-oblong with rounded ends, apiculate, 7-9 x 4-5 µ, walls smooth, hyaline, 0.2 µ thick, amyloid, often adhering in fours.
DISTRIBUTION: New Zealand.
HABITAT: Effused on bark of dead stems and branches.
Separated from other species bearing clavate acanthophyses by the small basidia, smooth elliptic oblong spores, and absence of clamp connections. The species resembles `Aleurodiscus' cerussatus (Bres.) H. & L. in surface features, presence of gloeocystidia, apically spined acanthophyses and smooth elliptical spores. It differs in that basidia are smaller, clamp connections absent, and spores are smaller and of different shape. In most collections the hymenial surface is white and remains so or changes to cream on drying; the collection from Coriaria arborea is rich cream with sulphur yellow areas where growing in bark crevices.
TYPE LOCALITY: Mt. Te Aroha, Auckland, New Zealand.

Dendrophyses are freely branched near apices and arranged at different levels in the hymenium; most are encrusted with fine crystals, either completely or with apices of a few branches and pedicels naked. Some of the context hyphae also are encrusted. Spores are mostly elliptical or obovate, apiculate, some obliquely so, thin-walled, smooth and nonamyloid. Walls soon collapse, and frequently spores adhere in fours. Corticium ampullosporum resembles A. acerinum in macrofeatures, thin context and elliptical smooth spores often adhering in fours; it differs in the absence of dendrophyses, smaller basidia, larger spores, and presence of clamp connections.
TYPE LOCALITY: Europe.
Acanthophysium australiense (Wakef.) G. Cunn. 1963
MYRTACEAE. Eucalyptus sp.: New South Wales, near Sydney.
Hymenophore annual, membranous, adherent, appearing first as numerous small irregularly disciform colonies 2-5 mm across, which merge to form irregular areas to 8 x 2 cm; margin free, lacerate, concolorous; hymenial surface alutaceous or tan, velutinate, not creviced. Context isabelline, to 0.5 mm thick, basal layer a narrow partly cemented zone of parallel hyphae, intermediate layer of erect hyphae partly cemented and compacted, embedding masses of crystals; generative hyphae 4-5 µm diameter, walls 0.25-0.5 µm thick, naked, with clamp connections. Acanthophyses subclavate when 28-32 x 6-8 µm, clavate and 50-60 x 14-16 µm, or cylindrical when 4-6 µm diameter, bearing upon the upper half crowded digitate processes which may attain a length of 4 µm. Gloeocystidia crowded in the hymenial layer and in irregular rows through the context, pyriform, fusiform, flexuous-cylindrical, or clavate, 35-86 x 6-22 µm, walls commonly smooth, sometimes bearing a few spines on the apical region. Hymenial layer to 80 µm deep, a compact palisade of basidia, paraphyses, acanthophyses, gloeocystidia, and paraphysate hyphae. Basidia cylindrical, 55-70 x 12-16 µm, bearing 4 spores; sterigmata arcuate, stout, to 10 µm long. Paraphyses clavate, 30-40 x 7-9 µm. Paraphysate hyphae cylindrical, moniliform, sometimes branched, not or slightly projecting, to 6 µm diameter. Spores obovate, elliptical, some compressed on one side, strongly apiculate, 20-26 x 14-18 µm, walls closely aculeate, hyaline, 0.2 µm thick, amyloid, spines to 4 µm long.
DISTRIBUTION: Australia.
HABITAT: Scattered on bark of dead branches.
Specimens from which the description has been drawn match the type ex "Queensland, Buderim Mt., 1912, C. T. White, No. 4" examined in Kew herbarium. The species may be recognised by the acanthophyses of various shapes and irregular gloeocystidia which together occupy the greater part of the context and hymenium, large spores with aculeate spines, and cylindrical, sometimes branched paraphysate hyphae. Basidia collapse when spores are about two-thirds developed so that it is difficult to ascertain their size or length of the sterigmata. Gloeocystidia when fresh are conspicuous, as contents stain deeply. Acanthophyses are present both in the hymenial layer and scattered through the context.
TYPE LOCALITY: Buderim Mountains, Queensland.

Basidia subclavate, some cylindrical, 20-30 x 5-6 µ, bearing 2-4 spores; sterigmata erect, slender, to 5 µ long. Paraphyses subclavate, 16-22 x 4-5 µ. Spores allantoid with rounded or acuminate ends, apiculate, 9-12 x 4-4.5 µ walls smooth, hyaline, 0.2 µ thick, amyloid.
DISTRIBUTION: New Zealand.
HABITAT: Crowded on bark of attached dead branches and dead standing saplings.
On examination the type of Hypocrea berggreni in Kew herbarium, ex "Maungatua, S. Berggren, No. 241" proved to be an Acanthophysium, identical with that later described as Aleurodiscus peziculoides. The species is endemic to New Zealand and found on four endemic species of Nothofagus, where it develops upon attached dead branches or dead standing saplings. At first, fructifications are small, pulvinate, scattered or crowded, and coloured cream or ochre. Later, between them develop others which become confluent, forming disciform fructifications with roughened surfaces, scalloped margins, and discoloured edges. Finally these larger plants become creviced so deeply that segments separate and persist as individual colonies, in this stage resembling mature fructifications of Stereum frustulatum, for which species they have been mistaken by several overseas workers. The older form is often biennial, reviving a second season. Fructifications then exhibit on the margins discoloured or black often zoned areas indicating stages of growth. In appearance these two stages are so diverse that each would be regarded as a different species if collected alone; but intermediate stages are present in collections listed showing transition from the pulvinate to the disciform condition. Both are identical in microfeatures.
Context hyphae and acanthophyses are similar to those of certain other species of Acanthophysium. Hyphae are thick-walled, and densely compacted so that basal tissues of the context appear sclerotioid, lumena often being capillary. Acanthophyses are abundant, subclavate, and bear upon the upper third crowded blunt spines. Basidia are much smaller than those of typical species of the genus, and bear delicate sterigmata. Gloeocystidia are large, abundant, with unusually thick walls in those present in the context. Spores are abundant, amyloid, and may be seen embedded in the hymenial layer as well as lying upon the surface when sections are treated with Melzer's reagent. When fresh, specimens are scented not unlike sandalwood.
Acanthophysium aberrans, A. apricans, A. australiensis, and A. berggreni form a small section linked by the clavate acanthophyses.
TYPE LOCALITY: Mt. Maungatua, Otago, New Zealand.

DISTRIBUTION: New Zealand.
HABITAT: Effused on bark of dead branches, twigs and standing dead saplings.
A. coralloides is common in New Zealand on four endemic species of Nothofagus. It may be identified by the chalk white (sometimes pink) deeply creviced hymenophore, oval irregularly aculeate spores, and thick-walled acanthophyses. The hymenophore, although appearing effused, is in reality composed of many small orbicular coalesced colonies. In sections each colony is apparent since the context hyphae develop from a small submerged base, and are arranged radiately from its centre. Hyphae merge with those of neighbouring colonies, at points of coalescence being less densely compacted. On the surface, margins of colonies are indicated by deep crevices.
Acanthophyses are produced in such masses that the scanty hymenium is masked, and give to sections their characteristic chalky appearance. They simulate pieces of coral, being short-branched, both stems and branches bearing spines and possessing walls so thickened that lumena are capillary. An almost endless variety of shapes may be seen in any section, so that exact descriptions are difficult to prepare. Among the acanthophyses are embedded the paraphyses and young basidia. The latter, when mature, elongate and project above the hymenial surface, produce spores, then collapse. Spores are formed in large numbers and may be found lying upon the surface and scattered through the hymenial tissues. Although appearing almost smooth in lactic acid aniline blue mounts, they are seen to be coarsely and irregularly aculeate when treated with Melzer's reagent.

EPACRIDACEAE. Cyathodes fasciculata: Auckland, Orere, Hunua Ranges, 300 m, type collection, P.D.D. herbarium, No. 12482.
Hymenophore annual, coriaceous, adherent, effused forming linear areas to 10 x 1 cm; hymenial surface white, then pallid cream, finally creviced; margin thinning out, white, fibrillose, adherent. Context white, 100-150 µ thick, basal layer of a few intertwined hyphae, intermediate layer scanty, of erect hyphae, embedding masses of crystals; generative hyphae to 4 µ diameter, walls 0.25 µ thick, naked, with clamp connections. Acanthophyses coralloid, arising from the base of the intermediate layer and forming the bulk of the hymenial layer, apically branched and covered with fine spines, some of the pedicels spinose, others naked. Gloeocystidia arising in the basal layer, some penetrating the hymenium, narrowly ovate, clavate, or broadly fusiform, 50-80 x 20-28 µ, apically crowned with irregular spinous processes. Hymenial layer to 60 µ deep, a scattered palisade of basidia, paraphyses, acanthophyses, and gloeocystidia. Basidia cylindrical, 50-65 x 12-14 µ, bearing 4 spores; sterigmata arcuate, subulate, to 16 µ long. Paraphyses cylindrical, fusiform, subclavate, or obclavate, irregular, 30-60 x 8-12 µ. Spores elliptical or obovate, strongly apiculate, 16-22 x 8-12 µ, walls delicately verruculose, hyaline, 0.5 µ thick, amyloid.
TYPE LOCALITY: Hunua Ranges, Auckland, New Zealand. DISTRIBUTION: New Zealand.
HABITAT: Effused on bark of dead branches and twigs.
Spines on spore walls may be seen only with an oil immersion objective, unless spores are treated with Melzer's reagent, when they become more conspicuous. Masses of crystals, often discoloured, are embedded in tissues of the context. Gloeocystidia are large, conspicuous, and bear irregular spines at or near apices. Acanthophyses are of the coralloid type but more delicate and thin-walled than those of A. coralloides. In macrofeatures the species resembles A. aurantium, and in New Zealand both develop upon the same host plant. Separation may be made by the different gloeocystidia and spores.

Dendrophyses parce ramosi, incrustati. Gloeocystidia absunt. Fasciculi 160-230 x 65- 90 µ, ad plurimum longitudineum eminentes. Basidia subclavata, 50-64 x 11-14 µ, 4 sporis. Sporae obovatae vel limoniformes, apiculatae, 13-16 x 8-12 µ, parietibus levibus, hyalinis, nonamyloidibus. On dead bark of Alectryon excelsus, Carterton, Wellington, N.Z.
Fascicles arise deeply within the context or from the base of the subhymenium, project for the greater part of their length, and are similar in structure to those present in species of Epithele. Spores and basidia collapse almost as soon as spores are shed. Dendrophyses may be naked or encrusted with fine crystals, the latter condition being common in sections from some plants, absent from others. Dendrothele Hoehn. & Litsch. was erected (1907, p. 820) on the presence of short fascicles, composed of dendrophyses which in the type species D. papillosa Hoehn. & Litsch. are freely laterally branched. In Acanthophysium fasciculatum they are formed from unbranched filiform context hyphae. Spores of the latter are similar in shape although smaller than those of D. duthieae Talbot (1956, p. 478).

From others possessing naked dendrophyses the species may be separated by the smooth globose spores and fusiform or clavate gloeocystidia crowded in the context and hymenial layer. The species resembles A. nivosum in certain macrofeatures, differing in that spores are smaller, dendrophyses naked, and the small gloeocystidia are crowded in the context and hymenium.

The type collection in Kew herbarium, ex "Wangaretta, Victoria" consists of eight small, irregularly orbicular colonies 1-5 mm wide. It is immature since spores were not found. Sections agree with the collections from Australia listed above, save that paraphyses are more clavate. The description given differs in several particulars from that of Hoehnel & Litschauer (1907, p. 809) which was drawn from specimens collected near the Murray River, Victoria. For they had described a different type of acanthophysis, and stated that spores were smooth. Basidia and paraphyses arise from the surface of the basal layer and are completely embedded in masses of acanthophyses which form the greater part of the context. At maturity basidia become elongated and. project above the hymenium, shed their spores, then collapse. Paraphyses remain deeply embedded. Gloeocystidia are scanty or abundant, apparently absent from some collections, assume many shapes, vary appreciably in size, and when fresh contain orange contents. In a previous paper (1956b, p. 259) I stated they were not present; but in a recent collection they were readily seen, and on re-examination of the other collections were found in some but not all, by aid of a differential stain. Fig. 101 was prepared from a section without gloeocystidia. Acanthophyses are coralloid and arise mainly from the surface of the basal layer. They are freely branched and usually clothed throughout with spines which in turn may branch. Spores are the largest recorded for the genus. In lactic acid aniline blue mounts they appear to be almost smooth; but in Melzer's reagent are seen to be covered with irregular aculeae which may reach a length of 3 µm. Early stages are cupulate or pezizaeform, and fructifications may remain so, or colonies fuse to form effused fructifications typical of most species of Acanthophysium. Pezizaeform plants could be placed under Aleurodiscus, but as their structure is corticioid, acanthophyses coralloid, and the species close to A. coralloides, it has been treated as an Acanthophysium.

Aleurocystis habgallae (Berk. & Broome) G. Cunn. 1956
PIPERACEAE. Macropiper excelsum: Auckland, Mt. Te Aroha, 520 m. Wellington, Rona Bay, 35 m.
Hymenophore annual, subgelatinous when fresh, horny when dry, irregularly scutellate, 2-10 mm diameter, or somewhat irregular and lobed; exterior surface finely tomentose, radially striate, at first white, drying brown; hymenial surface even, white, drying pallid flesh pink, or plum, not creviced. Context white, drying brown, 0.3-0.5 mm thick, of mainly radiately arranged parallel hyphae compacted and partly cemented; generative hyphae 4-5.5 µm diameter, walls 1-1.5 µm thick, with clamp connections; abhymenial hairs somewhat scanty and brief, arising directly from the basal hyphae. Metuloids arising in the subhymenium, projecting to 50 µm, fusiform, 60-110 x 16-30 µm, crystal encrusted throughout, walls 3-4 µm thick. Hymenial layer to 95 µm deep, a dense palisade of basidia, paraphyses, metuloids, and pseudophyses. Basidia clavate, 60-95 x 14-20 µm, bearing 4 spores; sterigmata arcuate, subulate, to 12 µm long. Paraphyses subclavate, 22-35 x 6-8 µm. Pseudophyses filiform, scarcely projecting, sometimes apically branched, to 4 µm diameter.

Context cream, to 2 mm thick, composed of several irregular chambers filled with spores. Spores globose, 17-20 µm diameter, walls smooth, tinted, to 3 µm thick, laminated, with 5-7 germ pores, nonamyloid.
DISTRIBUTION: Ceylon, Central and South America, South Africa, Tasmania, New Zealand.
HABITAT: Erumpent through bark of dead branches.
Both conidial and basidial fructifications are present on the same branches in the collection from Mt. Te Aroha, growing among one another, neither exhibiting an epigaean nor hypogaean position. Petch (1926, p. 79) demonstrated with cultures that both are stages in the life cycle of the species. Massee (1888, p. 176) claimed that his genus Matula, based on the conidial stage, produced basidia and figured one basidium [pl. IV, fig. 7] bearing two spores. He placed the species in a new order, Matuleae, which he claimed occupied a position exactly intermediate between the Nidulariaceae and Hymenogastraceae. Spores develop from apices of clavate conidiophores, not basidia, and from an early stage are enveloped in hyphae. When small they become detached and thereafter are nourished by the enclosing hyphae, which appear to act as nurse hyphae, as do those of certain species of Scleroderma. Sometimes hyphal fragments persist, attached to spore walls, giving the impression that spores are warted. Lloyd's four names were applied to different collections of A. hakgallae, as is evident from his descriptions, a sketch of the hymenium provided by Bourdot (1917, p. 656, fig. 937), and examination of an authentic specimen of 'A. capensis'. The sketch referred to shows the characteristic features of metuloids, basidia, and spores. Lloyd (1920, p. 930) noted, when discussing Aleurodiscus capensis, "If this proves to be the same as A. corneus I shall not be much surprised, although on comparison the plants do not seem to be the same, and I am unable to make out crested cystidia in this species". His "crested cystidia" were obviously basidia from which spores had been shed and sterigmata partly collapsed. When discussing A. capensis, Lloyd (1921, p. 1088) remarked "It is the only Aleurodiscus known with subgelatinous texture and cystidia except A. corneus which is probably the same". No reference occurs in any of his writings to 'Corticium' hakgallae, so that it is probable he did not examine specimens or realise he was dealing with that species. Martin (1942, p. 162), W. B. Cooke (1951, p. 208) and Doidge (1950, p. 484) treated Lloyd's four species as synonyms of Cytidia hakgallae. Either the conidial stage of this species, or a closely related one, was described as Michenera rompelii Rick (1904, p. 243). Lloyd (1908, p. 391) transferred it to Matula rompelii (Rick) Lloyd.

Separated from other species bearing clavate acanthophyses by the small basidia, smooth elliptic oblong spores, and absence of clamp connections. The species resembles `Aleurodiscus' cerussatus (Bres.) H. & L. in surface features, presence of gloeocystidia, apically spined acanthophyses and smooth elliptical spores. It differs in that basidia are smaller, clamp connections absent, and spores are smaller and of different shape. In most collections the hymenial surface is white and remains so or changes to cream on drying; the collection from Coriaria arborea is rich cream with sulphur yellow areas where growing in bark crevices.

HABITAT: Scattered or connate on bark of dead branches.
Pilei are at first small and orbicular, with margins plane or with edges slightly raised. Shortly they become connate, then forming linear areas. Each colony is apparent, nevertheless, and indicated by crevices where merging has occurred, and by points of attachment. Acanthophyses are of two types, one being similar to those of A. ochraceo-flavus, with densely arranged blunt spines crowded upon a cylindrical body; the second is composed of flexuous hyphae, bearing acuminate, often hooked large spines at intervals, often at bends. Both are crowded in the hymenial layer, form the tomentum of the exterior, and the second type occurs also in the context, sometimes almost replacing normal hyphae in the basal region. Spores are commonly D-shaped, with apical and basal apiculi. Others may be obovate with a basal apiculus often obliquely inserted, or obovate-elliptical with one side slightly flattened. Walls of spores are covered with closely arranged aculeae. Bases of a few basidia and paraphyses bear spines or irregular angular projections. Gloeocystidia are abundant and arise in the base of the subhymenium and superficial layers of the context; they extend to the hymenium, appearing at different levels therein, some penetrating to the surface. Most synonyms are given on the authority of Rogers & Jackson (1943, p. 267); others as a result of examination of authentic specimens. One collection from New Zealand, ex "Crows Nest, Kaiwarra" was in Kew herbarium filed under the cover of Stereum ochroleucum Fr. Three, ex "Colenso b258, b590 and b729" were placed under the cover of Aleurodiscus oakesii (B. & C.) Cke.

A. ampla may be recognised by the white, tomentose fructifications frequently pendent by a narrow vertex, with dark plum or purple hymenial surface, subgelatinous context, and narrow suballantoid, nonamyloid spores. In macrofeatures fructifications resemble scattered pilei of Stereum purpureum, from which the species is readily separated by the absence of the zone of vesicles which characterises the former. Formerly I recorded (1956, p. 232) the species under the name of Cytidia flocculenta, and Cleland (1935, p. 262) also recorded its presence in South Australia under this name. Donk (1959, p. 78) has shown the species to be Auriculariopsis ampla, although inadvertently he had recorded it both as Cytidia salicina (p. 74) and A. ampla (p. 78).

Context of a few repent hyphae 6-8 µm diameter, walls 0.2-0.5 µm thick, with clamp connections; fertile hyphae erect, bearing lateral branches in botryose or coralloid clusters forming a dense zone near the surface. Basidia developing at ends of lateral branches singly or in groups of 2-4, subclavate, a few cylindrical, 8-12 x 5-7 µm, bearing 6, sometimes 8 spores on slender sterigmata 2-4 µm long. Paraphyses clavate, 6-8 x 4-5 µm. Spores narrowly fusiform or naviculate, with bluntly acuminate ends, a few ovate, apiculate, 6-8 x 2.5-3.5 µm, walls smooth, hyaline, 0.1 µm thick.

HABITAT: Effused on bark or decorticated decaying wood.
Collections agree with specimens of 'Corticium subcoronatum' examined in Kew herbarium, differing in the slightly smaller more subclavate basidia. The species may be separated from others possessing clamp connections by the small, fusiform or naviculate spores. Branchlets are arranged irregularly, some in coralloid groups, others in cymes. Although basidia collapse early, spores long remain attached by the sterigmata. Oil globules are abundant in the repent hyphae and main branches of the fertile hyphae.

HABITAT: Effused on bark and decorticated wood of dead branches.
Collections agree with authentic specimens of C. arida examined in Kew herbarium. The species differs from the related C. betulae in surface features and especially the hyaline, naked, slender hyphae of the context which are not inflated between septa, absence of cordons, narrower spores with thinner walls, and more clavate basidia. C. arida produces a destructive decay of worked timber.

Hymenial layer to 65 µm deep, a loose palisade of basidia and paraphyses. Basidia subcylindrical, 35-60 x 6-7 µm, bearing 2-4 spores; sterigmata arcuate, to 6 µmlong. Paraphyses subclavate, 18-35 x 5-6 µm. Spores elliptical, oval, obovate, or pip-shaped, sometimes flattened on one side, apiculate, occasionally obliquely so, 10-13 x 6-9 µm, walls smooth, ferruginous, 0.75 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, Australia, New Zealand.
HABITAT: Effused on bark, decorticated wood and worked timber.
Surface features of C. betulae and C. arida are practically identical. Microfeatures are distinct, however; for in C. betulae context hyphae are of greater diameter, often inflated between septa, frequently compacted into cordons near the base, encrusted, especially near the base, with coarse crystals, and usually tinted brown. Basidia are subcylindrical and narrower than those of C. arida, and spores are more irregular in shape, slightly larger, and possess thicker walls. Like C. arida the species produces a destructive decay of worked timber. The type of Thelephora luteocincta in Kew herbarium, ex "Victoria, Wangaretta" was found to be based on a fragmentary specimen of C. betulae.

Coniophora olivacea (Fr.) P. Karst. 1882
FAGACEAE. Nothofagus fusca: Nelson, Staircase Creek, Reefton, 700 m.
Hymenophore annual, sometimes reviving a second season, loosely attached, effused forming linear areas to 10 x 2 cm; hymenial surface ferruginous, becoming umber, sepia, or olivaceous, velutinate, even, not creviced; margin thinning out, adherent, strongly fibrillose, pallid tan. Context to 500 µm thick, ferruginous, of intertwined hyphae not differentiated into intermediate and basal layers; generative hyphae 4-6 µm diameter, walls 0.5 µm thick, chestnut, branched, inflated to 12 µm inoccasional cells, coated with sparse gelatinous warts. Cordons numerous, scattered in the base, formed from 7-28 partly cemented hyphae. Septocystidia arising in the base of the hymenial layer and projecting to 10 µm, also scattered in the context, cylindrical, septate, 80-180 x 10-16 µm, walls chestnut, 1-3 µm thick, coated with granules of mucilage arranged in irregular warts. Hymenial layer to 120 µm deep, a dense palisade of basidia, paraphyses, septocystidia, and paraphysate hyphae. Basidia subclavate, 30-45 x 6-8 µm, bearing 2-4 spores; sterigmata arcuate, to 6 µm long. Paraphyses subclavate, 18-30 x 5-6 µm. Paraphysate hyphae 4-6 µm diameter, hyaline, slender, septate, projecting to 40 µm. Spores obovate, elliptical, pip-shaped, or naviculate, often flattened on one side, apices rounded or slightly acuminate, bases apiculate, 10-13 x 5-7 µm, walls smooth, ferruginous or chestnut, 0.5 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, South Africa, New Zealand.
HABITAT: Bark of decayed branches and trunks.
Readily recognised by the large septocystidia which may project for as much as 110 µm and give to the hymenial surface its velutinate appearance. Hyphae of the context are brown, frequently inflated between septa, and near the base often compacted into cordons. Spores vary appreciably in shape and size. Although Bourdot & Galzin (1928, p. 362) recorded the presence of rare clamp connections, they were not seen in specimens examined in Kew herbarium, nor in collections from this region. As the synonymy shows, based for the most part on the list given by Rogers & Jackson (1943, p. 273), the species bears many names, erected mainly on slight differences in shape and size of septocystidia, or colour variants of the hymenial surface.

Corticium cebennense Bourdot 1910
RUBIACEAE. Coprosma australis: Auckland, Ruatewhenua, Waitakere Ranges, 300 m.
Hymenophore annual, membranous, somewhat loosely attached, effused forming small linear colonies 2-6 x 2-3 cm; hymenial surface white, drying cream or pallid straw, even, not creviced; margin thinning out, white, arachnoid, adherent. Context white, 100-200 µm thick, basal layer narrow, of parallel hyphae, intermediate layer of erect loosely arranged hyphae branched at a wide angle; generative hyphae 4-5 µm diameter, walls 0.2 µm thick, naked, with clamp connections. Hymemal layer to 50 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate or subcylindrical, 20-26 x 5-6 µm, bearing 2-4 spores; sterigmata slender, 7-10 µm long. Paraphyses subclavate, 18-22 x 5-6 µm. Spores allantoid, or rod-shaped with rounded ends, 7-9 x 1.5-2 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Europe, New Zealand.
HABITAT: Effused on decorticated dead wood.
Context hyphae are naked and the context is without crystals or granules of mucilage. Specific features are the long and narrow allantoid or rod-shaped spores with two prominent guttulae, moderately thick hyphae branched at a wide angle, and small elliptical colonies with cream or ochre, even, non-creviced surface. Our collection agrees with a specimen ex Stockholm examined in Kew herbarium, differing in being non-creviced, and growing upon a different host. In microfeatures they agree closely.

Corticium comedens (Nees) Fr. 1838
FAGACEAE. Nothofagus cliffortioides: Nelson, Lake Rotoiti, 700 m. Nothofagus menziesii: Hawke's Bay, Upper Mohaka Valley, 700 m; Poronui, Kaiwaka Ranges, 650 m. Nelson, Marble Hill, Maruia, 900 m. Otago, Otautau, 350 m.
Hymenophore annual, ceraceous, adherent, erumpent from beneath bark, effused forming linear areas to 30 x 10 cm; hymenial surface at first orange, then reddish-brown, Indian red or lateritius, even, becoming scantily creviced, gelatinous when moist; margin irregular, orange, floccose or sometimes scantily rhizomorphic. Context reddish-brown, 60-100 µm thick, basal layer of parallel hyphae scantily developed, intermediate layer of erect hyphae compacted with mucilage; generative hyphae 3-4 µm diameter, walls 0.2 µm thick, encrusted with orange mucilage granules, flexuous, with clamp connections. Hymenial layer 60-120 µm deep, a close palisade of basidia, paraphyses, and paraphysate hyphae encrusted with mucilage granules. Basidia clavate, 35-112 x 6-16 µm, bearing 2-4 spores; Sterigmata stout, to 10 µm long. Paraphyses subclavate, 30-60 x 4-6 µm. Paraphysate hyphae projecting, apically scantily or freely branched, naked, 3-4 µm diameter. Spores allantoid, 16-24 x 5-7 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Europe, Great Britain, New Zealand.
HABITAT: Erumpent through bark of dead branches.
C. comedens develops beneath bark, soon becoming erumpent, the ruptured bark then curling away to expose the semigelatinous hymenophore. At first bright orange, especially near margins, the hymenial surface soon changes to the colour of deeply burned brick, finally becoming reddish brown. Although sections are reddish, context hyphae are hyaline, colour being supplied to sections by masses of orange mucilage granules encrusting hyphal walls, basidia, paraphyses, and filling interstices between. Paraphyses, although numerous, are often overlooked, since in sections they are almost hidden by the large basidia. Some develop deeply within the intermediate layer, when they may be mistaken for gloeocystidia: Maire stated that spores germinate by repetition; but that is not supported by one collection at hand in which spores were seen to produce hyphae in the usual manner. For this and other reasons he placed the species under Vuilleminia. Gaumann (1926, p. 489) placed the species under the Vuilleminiaceae, a family he erected to contain this one species, which he held to be a heterobasidiomycete. In a later work (1949, p. 263) he recognised the genus but returned it to the Corticiaceae.

Spores subglobose or oval, 7-9 µm diameter, or 7-9 x 6-7 µm, walls smooth, hyaline, 0.5 µm thick.
DISTRIBUTION: Northern Europe, New Zealand.
HABITAT: Effused on bark or decorticated wood of living or dead trunks and branches.
Tissues are so packed with crystals, which extend between basidia and paraphyses, that the hymenophore appears chalky and is difficult to section. As with many species of Corticium, different collections vary appreciably from one another in certain features. Those on Dodonaea and Podocarpus consist of numerous small elliptical colonies 5-15 mm long growing on living bark; on dead wood of Coprosma foetidissima they are continuous and extend to 15 cm; on dead wood of Fuchsia excorticata both conditions are present. Thickness of the context varies from 10 to 120 µm, with consequent differences in structure, thin plants possessing a scanty intermediate layer, whereas in thick specimens this tissue is well developed. When plants are growing on decorticated wood margins are often outlined by brown or black lines in the wood. Surface tissues are readily eaten by snails or insects. Spores are more globose or oval than those seen in European specimens, but in other features agree. Basidia with two or four spores occur in both, so that it would appear as if the original description and illustration were prepared from an immature specimen, since they call for basidia with two sterigmata and an occasional aborted third.

Numerous small colonies first appear and soon merge to form linear fructifications which may attain a length of 25 cm. Crystals are common in old specimens, usually lying between basal and intermediate layers, sometimes in lenticular or conical cavities. Old specimens are somewhat stratose, displaying two or three layers usually vaguely defined. Hyphal walls become partly gelatinised and pseudoparenchymatous. Surface colour varies from cream, argillaceous, alutaceous, to pinkish-buff. The species is separated from C. rickii by the large spores of different shape and larger basidia.

Spores are allantoid and often attenuated from rounded bases to apices. Occasional crystals were noted in the tissues of some specimens but were absent from most. The species differs from C. filicinum in the unusual spores, presence of paraphysate hyphae, and subclavate paraphyses. Context hyphae are more strongly developed, slightly thinner, and are without ampullae. Although treated as a subspecies of C. lembosporum by Bourdot & Galzin (1928, p. 208), the plant is sufficiently well defined to maintain as a species.

On decayed wood of Nothofagus menziesii, Tuatapere, Otago, N.Z.
"Stephanocysts" are abundant, one-celled, stain deeply with aniline blue, and bear several long flagella upon the distal hemisphere of each. Capitate paraphysate hyphae are abundant in the hymenial layer and stain deeply with aniline blue.
Plants are resupinate and grow closely attached to the substratum, which supplies necessary support to the fructification. The hyphal system is monomitic, composed of generative hyphae alone, and there are no abhymenial hairs, or cortex, as in Stereum illudens.
The context is represented by a basal layer (fig. 2, a) of loosely arranged hyphae lying parallel with the substratum, and an intermediate layer (fig. 2, b) of mainly erect hyphae. Branches of hyphae arising from the basal layer penetrate the substratum, and lateral branches arise from erect hyphae of the intermediate layer to produce small vesicles, some of which bear flagella on the distal hemisphere.
The hymenial layer (fig. 2, c) is composed of a close palisade of basidia, paraphyses, and gloeocystidia. The last project slightly, and are slightly capitate. Basidia are subclavate and carry on slightly arcuate sterigmata four obovate or elliptical spores. Hyphae are naked and clamp connections are present at all septa.

Poa bulbosa: South Australia, Meningie.
Hymenophore annual, ceraceous, growing from surfaces of culms and leaves of grasses, as clavariform or fuciform single or branched sometimes antler-like processes, each long-aculeate or subulate, 5-25 mm long; hymenial surface flesh-pink or coral-pink, remaining so or drying pallid tan. Context of closely compacted parallel hyphae often breaking into oidia near apices, intermediate layer scanty or wanting; generative hyphae 6-7 µm diameter, walls 0.2 µm, thick, naked or encrusted with orange mucilage granules, without clamp connections. Hymenial layer developing both upon the exterior of host tissues and the subulate processes, a dense palisade of basidia and paraphyses. Basidia subclavate, 16-20 x 5-6 µm, bearing 4 spores; sterigmata stout, to 6 µm long. Paraphyses subclavate, a few slightly capitate, 16-18 x 5-6 µm. Spores elliptical, with rounded ends, a few irregularly suballantoid, apiculate, 8-11 x 4-5 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Great Britain, North America, Australia, Tasmania, New Zealand.
HABITAT: Parasitic upon culms and leaves of grasses.
Although represented in the herbarium of Plant Diseases Division by only a few collections, the species is common through the North Island of New Zealand on certain European grasses of pastures, lawns, golf courses, and bowling greens. It kills plants, forming discoloured orbicular areas from a few centimetres to upwards of one metre in diameter. First found in 1854 at Mt. Gambier, it has become widespread in Australia, Tasmania, and New Zealand, and more recently established in Great Britain and the eastern coast of the United States. C. fuciforme may be recognised readily by the bright flesh-pink or coral, clavariform, semigelatinous bodies produced on killed culms and leaves. Bodies are sometimes sterile, or produce only a few oidia; they are as frequently fertile, bearing a palisade hymenium similar to that developing on killed culms and leaves.

Corticium griseliniae G. Cunn. 1963
Specific features are the small, globose, verruculose spores, slender frequently inflated paraphysate hyphae, and encrusted hyphae embedding masses of crystals. The hymenial surface is finely tuberculate, suggesting a Grandinia, but in the context there is no suggestion of regular spines. When old it is also coloured alutaceous in irregular patches. Plants are chalky and brittle, consequently difficult to section.
As in C. flagellatum, the context is composed of a basal layer (fig. 3, a) of repent hyphae from which arise hyphae of the intermediate layer (fig. 3; b), branched at a wide angle, scantily developed, and embedding masses of calcium crystals. The hymenial layer (fig. 3, c) consists of a narrow subhymenium and a palisade of basidia, paraphyses, and paraphysate hyphae. The last project and are cylindrical, aculeate, or capitate. Spores are globose with finely verruculose walls. Clamp connections are present at all septa.
Below is given a general account of the morphology of the types of hymenophore present in different species and genera, together with particulars of ancillary organs which may be present in the tissues.

HABITAT: Effused on bark or decorticated dead branches.
Collections listed agree with European specimens examined in Kew herbarium, differing in the slightly larger spores and more vivid colours of the surface. At first plants are pelliculose, alutaceous, waxy, and adherent; in more mature specimens they appear pruinose, livid, or reddish-brown, and often plum colour where fertile. Context tissues are encrusted with mucilage granules and interstices filled with them so that sections appear reddish-brown and glistening. In old specimens the surface may be creviced, though sparingly. The basal layer is normally thick, occupying about half the context; in several collections it is thin, or tissues may be zoned with two or three narrow bands of parallel hyphae and erect intermediate hyphae alternating. Occasional plants display a few paraphysate hyphae with apices bearing from one to three short branches. Bridging hyphae are not uncommon. From C. leptospermi and C. vitellinum the species may be separated by the larger basidia, context hyphae of greater diameter, larger spores, and different structure of the context.

Hyphae branch at a wide angle, and septa are widely spaced save in hyphae of the subhymenium. Bridging hyphae are not uncommon. Spores often adhere in fours; in most collections they are obovate or elliptical, in others they may be oval and more distinctly verruculose. Walls of some spores are hyaline, others faintly tinted brown, as may be seen in sections mounted in lactic acid, and may stain with aniline blue. Many are delicately somewhat irregularly asperulate, others bear delicate markings confined to the apical region. The species differs from the European C. alboochraceum Bres. in that spore markings are much finer and context hyphae are not ampullate.

Hymenophore annual, ceraceous, adherent, composed of numerous small orbicular colonies 5-10 mm diameter which commence at lenticels, often becoming fused to form linear areas to 5 cm long; hymenial surface cream or pallid ochre, usually raised and darker towards the centre, becoming creviced; margin thinning out, pallid cream, finely byssoid, adherent. Context cream, 100-500 µm thick, basal layer stout, of compact parallel hyphae, intermediate layer of mainly erect hyphae, sometimes embedding masses of crystals; generative hyphae 3-4 µm diameter, walls 0.2 µm thick, naked, with clamp connections. Gloeocystidia arising from the intermediate layer, fusiform, ventricose, or obclavate, some flexuous-cylindrical, apices long-acuminate, some projecting slightly, 40-80 x 6-8 µm. Hymenial layer to 40 µm deep, a close palisade of basidia, paraphyses, and gloeocystidia. Basidia subclavate, 24-32 x 5-6 µm, bearing 2-4 spores; sterigmata slender, to 6 µm long. Paraphyses subclavate, 10-18 x 4-5 µm. Spores broadly elliptical, pip-shaped, or obovate, 6-9 x 3-4.5 µm, walls smooth or delicately irregularly verruculose, hyaline, 0.2 µm thick; sometimes adhering in pairs or fours.

Diagnostic features are the usually orbicular colonies often commencing from lenticels, with cream, creviced surface; densely compacted parallel hyphae of the basal layer, somewhat loosely arranged erect hyphae of the intermediate layer sometimes embedding crystals, pip-shaped spores often adhering in fours, and obclavate gloeocystidia with long-acuminate apices extending to the surface of the hymenium. Several forms have been described as species. C. pruni is one with nonamyloid smooth spores, obclavate gloeocystidia with long acuminate apices, and a stout basal layer. Collections from apricot, cherry, and peach match this form. Collections from Albizzia and Beilschmiedia possess delicately granular-verruculose amyloid spore walls which Rogers & Jackson (1943, p. 302) described for the type form. Burt described C. vesiculosum from an old specimen in which gloeocystidia had collapsed, leaving cavities in the context, a condition not uncommon in old specimens at hand. Practically every section examined shows a somewhat different microstructure, consequently it is advisable to regard all as forms of one variable species, as Rogers & Jackson have done. In general, thick specimens have longer gloeocystidia and more of them in the lower portions of the context. Crystals may be present in or absent from different sections taken from the same specimen. A few lateral vesicles, similar to those of C. utriculicum have been noted in the base of the context in a few sections.

C. pteridophilum is one of three species growing upon dead pendent stipes of tree ferns. From the others, C. confusum and C. filicinum, it is separated by the gloeocystidia and broadly fusiform spores. In shape and arrangement of the small gloeocystidia the species resembles C. lianacolum, differing in the broadly fusiform spores and membranous hymenophore. It has similar gloeocystidia and habitat to `Gloeocystidium' cretatum Bourd. & Galz., from which it is separated by the much larger spores of different shape, and wider basidia. Crystals may be present in or absent from different parts of the same specimen; when present they are packed in an irregular zone in the intermediate layer.

DISTRIBUTION: Ceylon, East and West Indies, India, North America, Samoa, New Zealand.
HABITAT: Parasitic on branches, twigs, and leaves.
Specimens from which the description was drawn were collected upon living apple twigs and branches, taken from a neglected orchard. The fungus forms cankers upon these, many small laterals being killed. Although a common parasite in tropical regions, where it has been recorded on citrus, cocoa, rubber, and tea, it has also been recorded as attacking fig and apple trees in Louisiana by Edgerton (1911) under the name of Corticium laetum, a species not present in North America, according to Rogers & Jackson (1943, p. 296). The fungus is unusual in possessing a conidial stage, described as Necator decretus by Massee. Rant (1912) showed by the aid of cultures that it was a stage in the cycle of the species. C. salmonicolor may be identified by the large-diameter basal hyphae with thick walls, absence of clamp connections, dense basidial layer, somewhat large clavate basidia with brief sterigmata, and large oval or subglobose spores. Basidia and paraphyses develop in corymbs, although this can be seen only in sections from developing margins. Although Dastur placed the species under Pellicularia, its only resemblance to members of that genus lies in the stout basal hyphae, development of context and hymenium being typically that of Corticium. Its relationship lies with C. fuciforme, which exhibits somewhat similar stout hyphae, the contents staining deeply with aniline blue.

Context white, 200-300 µm thick, sometimes 500-600 µm when vaguely layered, basal layer narrow, of parallel compact hyphae, intermediate layer of erect hyphae embedding masses of crystals and mucilage granules; generative hyphae 4-6 µm diameter, commonly 3.5-4 µm, walls 0.5-1 µm thick, encrusted, with clamp connections. Hymenial layer to 40 µm deep, a dense palisade of basidia, paraphyses and paraphysate hyphae. Basidia subclavate, 12-24 x 4-6 µm bearing 4 spores; sterigmata slender, to 5 µm long.

DISTRIBUTION: North America, West Indies, South Africa, Australia, New Zealand.
HABITAT: Effused on bark or decorticated dead branches and stems.
Collections agree with the type in Kew herbarium, ex "South Carolina, No. 2473" save that paraphysate hyphae are usually more strongly developed. Occasional paraphysate hyphae are crystal encrusted either at apices or crystals are arranged in a band beneath the naked apices. The species might therefore be regarded as a Peniophora, but without justification since crystals are accidental, being present on or absent from hyphae in different sections from the same specimen. In the context, crystals are copiously developed and give to sections a chalky appearance. Several collections exhibit rhizomorphs which at first are peripheral but later may become covered by the developing hymenium. Specimens are often sterile, especially if large. The species resembles C. corniculatum in many macrofeatures, but may be separated by the narrower elliptical spores and cylindrical paraphysate hyphae.

Hymenophore annual, arachnoid, adherent, effused forming small irregular areas to 8 x 3 cm; hymenial surface sulphur yellow or chrome, farinose, not creviced; margin thinning out, arachnoid, concolorous, adherent, sometimes rhizomorphic. Context yellow, either composed of rhizomorphic strands each formed from 2-6 cemented hyphae with a loose weft of solitary hyphae between, forming a scanty reticulated tissue to 30 µm deep; or of an intermediate layer of mainly erect hyphae arising from a narrow basal layer of a few repent hyphae and embedding numerous spores; generative hyphae 3-6 µm diameter, walls 0.2 µm thick, often encrusted, sometimes inflated between septa, with clamp connections. Hymenial layer either a continuous palisade, or composed of short lateral branches arising from rhizomorphs and bearing 2-5 basidia and paraphyses. Basidia cylindrical or subclavate, 8-12 x 6-7 µm, bearing 4 spores; sterigmata slender, to 6 µm long. Paraphyses subclavate, 6-8 x 5-6 µm. Spores subglobose, oval, or broadly elliptical, 5-7 x 4-5.5 µm (including spines), walls finely and closely echinulate, hyaline, 0.2 µm thick; spines to 4 µm long.
DISTRIBUTION: Europe, Great Britain, North America, New Zealand.
HABITAT: Effused on decorticated. decayed wood and fern stipes.
Taxonomists differ as to whether the species should be placed under Corticium or Tomentella. Because spores are hyaline and the hymenium is frequently arranged in the form of a definite palisade, it is treated as a Corticium herein. The collection from the Ruahine Ranges exhibits the Tomentella structure, the others the Corticium form seen in some European collections. The species may be separated from C. tulasnelloideum, which it resembles in the echinulate spores, by the conspicuous yellow colour of the surface and usual presence of rhizomorphs either in the context or at margins. Colour sometimes fades from the central portions, but is retained in the margins. An extensive synonymy is given by Rogers & Jackson (1943, p. 308).

HABITAT: Effused on bark or decorticated dead branches.
Collections listed agree with a specimen of C. tuberculatum examined in Kew herbarium, differing mainly in the brighter colour of the surface and, particularly, in the masses of crystals present in the context. In specimens from Griselinia lucida crystals are confined to the basal part of the context, whereas in those from Nothofagus cliffortioides they extend to the hymenial layer, lying between and partly encrusting basidia and paraphyses. Australian collections bear only a few crystals, hyphae of the context being encrusted with mucilage granules. Margins of crevices in old specimens often lift slightly and give to plants an odontoid appearance. When plants are actively growing the surface is even although deeply creviced.

Specific features are the echinulate, subglobose, or obovate spores, small basidia, subclavate or elliptical paraphyses, non-creviced surface which on a dark substratum appears as a delicate grey or bluish-grey arachnoid film, and absence of an intermediate layer. Appreciable variations were noted in specimens examined, particularly in thickness of the context, shape and size of spores, and presence or absence of ampullae on context hyphae. The context is reduced to a basal layer of mainly parallel hyphae, which soon collapse and become pseudoparenchymatous. Spores are.similar in size and echinulations to those of C. sulphureum, differing mainly in shape and finer spines.

Gloeocystidia flexuoso-cylindricalia vel subclavata, 45-110 x 10-12 µ. Basidia clavata, 45-64 x 11-14 µ. Sporae ovales vel aliquot subglobosae, 8-11 x 7-9 µ, parietibus levibus, hyalinis. On dead decorticated wood of Griselinia littoralis, Mt. Ruapehu, Wellington, N.Z.
Basidia are abundant and project slightly when fertile, whereas paraphyses are scanty, slender, and seldom more than half their length. Gloeocystidia are irregular both in shape and size. Many of small size are crowded near the base; others pass from the base into the hymenium, but few project. Most are submoniliform, some cylindrical and sometimes strangulated near apices. Superficially plants resemble some collections of C. patricium.
In an earlier paper (1954, p. 290) I referred the species to C. radiosum Fr. As J. Boidin has pointed out it differs from this species in the larger nonamyloid spores and presence of clamp connections.

Hyphae generatoriae afibulatae, 2 .5-4.5 µ, diam. Gloeocystidia cylindricalia, apicibus rotundis, 50-75 x 6-9 µ. Basidia subclavata, 30-45 x 6-8 µ, 2-4 sporis. Sporae ovales, aliquot subglobosae, 7-9 x 5-6 µ, parietibus levibus, hyalinis. On dead bark of Coprosma australis, Mt. Egmont, Taranaki, N.Z.
Commonly cream, egg-yolk yellow, or ochre, the hymenial surface may become the yellow-green of ripening lemons, salmon, or where rubbed or chewed by insects, brick red. All these colours may be seen in several of the specimens. The testaceous colour is produced by granules of soluble mucilage which coat hyphae of the upper part of the context. Gloeocystidia are conspicuous and do not collapse; they resemble those of C. patricium, although appreciably smaller. From the latter species separation is made by the differently shaped, smaller spores, smaller gloeocystidia, and absence of clamp connections. Plants stain wood of the substratum yellow. Clamp connections are absent from this and the two following species C. afibulatum and C. crystallitectum.

HABITAT: Effused on bark of dead branches and dead stipes of tree ferns.
In C. vescum the hymenophore develops as a tenuous white, sometimes pelliculose film attached firmly to the substratum, following closely its irregularities and resembling a light grey wash of water colour. The context is usually scanty, consisting of a few mainly parallel hyphae which soon collapse and become partly gelatinised; in some collections it may attain the thickness of 50 µm. An intermediate layer is wanting, the hymenium arising from short branches of the basal layer. Obpyriform or ovate paraphyses are common and form the bulk of the hymenial layer. In the collection from Rubus cissoides most paraphyses are obpyriform or ovate, whereas in those from Neopanax colensoi and Myrsine australis they are ovate, pyriform, cylindrical or subglobose.

Hymenophore pileate, annual, coriaceous, appearing first as scattered orbicular colonies 2-10 mm diameter, when sessile-umbonate with free margins, merging to form linear areas to 8 x 3 cm. Pilei either conchiform-umbonate when solitary and imbricated, or narrowly effused-reflexed, 1-3 cm wide, 1-6 cm long; pileus surface tan, chestnut, or umber, tomentose, abhymenial hairs sometimes arranged in concentric bands of different shades of brown, imbricate and silky, or with depressed or raised parallel concentric ridges and frequently radiately grooved or plicate; hymenial surface at first bay, fulvous, smoky brown, chestnut, or cinnamon, becoming darker when old, tardily creviced either in radiate series, or areolately; margin thinning out, fibrillose, crenate, at first pallid grey, becoming darker, finally concolorous, free. Context tan or ferruginous, 0.3-0.8 mm thick, of parallel hyphae radiately arranged; skeletal hyphae 4-5 µm diameter, walls 1 µm thick, yellow brown; generative hyphae 3-4 µm diameter, walls 0.2 µm thick, hyaline, with clamp connections. Pseudosetae filiform with slightly inflated apices, in sterile plants a few showing false septa, walls brown, thin and encrusted with fine crystals, in fertile specimens walls thickened to 2 µm, seldom septate, encrusted. Hymenial layer when fertile a close palisade of basidia, paraphyses, and scattered pseudosetae, when sterile appearing as a loose palisade of pseudosetae. Basidia subclavate, 24-30 x 7-8 µm, bearing 4 spores; sterigmata erect, slender, to 6 µm long. Paraphyses subclavate, 16-22 x 5-6 µm.

DISTRIBUTION: South Africa, Australia, New Zealand.
HABITAT: Bark or decorticated wood of dead fallen trunks and stems.
Collections match the type of Stereum schomburgkii in Kew herbarium, ex "Port Denison, Queensland". Talbot (1954, a, p. 316) found this to agree with the type of Thelephora (Stereum) fulva in the herbarium of Paris National Museum, ex "Cap-de-Bonne-Esperance, Drege, 9441". Colour of the surface is at first cinereous, tan, or hazel; later, when pseudosetae replace the basidia, it becomes much darker. D. monomitica resembles D. fulva in macrofeatures, differing mainly in form and colour of the pilei. It differs appreciably in microfeatures; for in D. fulva the hyphal system is dimitic, clamp connections are present in generative hyphae, pseudosetae are of different shape, appreciably thicker in the walls, usually verruculose, and spores are of different shape and slightly larger. As was pointed out by Talbot, the hymenium develops at an early stage, to be replaced by pseudosetae as plants age. In fertile plants the hymenium is composed of a dense palisade of basidia and paraphyses through which scattered pseudosetae project, most forming a dense palisade in the subhymenium. Later the hymenium disappears, when the palisade of pseudosetae takes its place, plants then becoming darker on the hymenial surface.

Hymenophore annual, membranous, adherent, forming orbicular or linear maculiform areas 2-15 mm across, sometimes merging to form linear areas to 12 cm long; hymenial surface white, velutinate, minutely areolately creviced; margin thinning out, concolorous, arachnoid, adherent. Context white, 10-30 µm thick, basal layer of a few repent hyphae firmly cemented, intermediate layer of mainly erect hyphae more freely branched in the subhymenium, pseudoparenchymatous when old; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, with clamp connections. Fascicles arising from the basal layer and projecting for the greater part of their length, 8-10 per mm, cylindrical with penicillate apices, 90-130 x 12-25 µm, composed of 20-45 thin-walled sparsely septate hyphae closely arranged, sometimes branched near apices. Hymenial layer to 30 µm deep, a close palisade of basidia and paraphyses interrupted by the fascicles. Basidia subclavate, 12-18 x 5-6 µm, bearing 2-4 spores; sterigmata arcuate, slender, to 6 µm long. Paraphyses subclavate, 8-14 x 4-5 µm.

DISTRIBUTION: France, New Zealand.
HABITAT: Effused on dead stipes of tree ferns and bracken and rhizomes of climbing ferns.
Fascicles are delicate, readily fractured, cylindrical with penicillate apices, and composed of compact, thin-walled generative hyphae sometimes sparsely branched near their apices. Spores are suballantoid with acuminate bases, or pip-shaped, and frequently adhere in pairs or fours. In actively growing specimens the context is composed of basal and intermediate layers; shortly tissues become compacted and pseudoparenchymatous, so that details of structure can be ascertained only from sections taken from near the growing periphery. Collections agree with a specimen examined in Kew herbarium, ex "Aveyron, France, herb. Bourdot, No. 8053". The species is confined to dead stipes of ferns both in France and New Zealand, in this region being associated with Corticium confusum, C. filicinum, C. pteridophilum, and Tubulicrinis vermicularis.

Hymenophore annual, membranous, adherent, effused forming irregular areas to 15 x 4 cm, with numerous irregularly orbicular outlying islands; hymenial surface white, becoming cream, velutinate, even, not creviced; margin thinning out, concolorous, adherent. Context white, 25-70 µm thick, basal layer of parallel skeletal hyphae, occupying about half the context, intermediate layer scanty, of branched hyphae mainly ascending, and usually embedding masses of crystals; skeletal hyphae 3-3.5 µm diameter, walls so thickened that lumena are capillary; generative hyphae 2-2.5 µm, diameter, walls 0.25 µm thick, naked, with clamp connections. Fascicles arising from the basal layer, projecting for the greater part of their length, 8-10 per mm, subulate with broad bases and bluntly acuminate or rounded apices, 150-205 x 30-50 µm, composed of 50-110 skeletal hyphae sometimes tapering, where exposed encrusted with fine crystals and in old specimens often enmeshed in irregular hyphal sheaths. Hymenial layer to 30 µm deep, a close palisade of basidia and paraphyses interrupted by fascicles. Basidia at first cylindrical, becoming somewhat cucurbitiform with inflated bases, 24-30 x 8-10 µm, bearing 4 spores; sterigmata stout, arcuate, to 12 µm long. Paraphyses subclavate or clavate, 18-22 x 8-10 µm. Spores clavate-naviculate, apices bluntly rounded, bases apiculate, 12-16 x 5-6 µm, walls smooth, hyaline, 0.2 µm thick; often adhering in fours.
DISTRIBUTION: New Zealand.
HABITAT: Effused on dead pendent and fallen stipes
Both basal layer and fascicles are composed of skeletal hyphae. Fascicles are encrusted with fine crystals where exposed, and, as hyphae are firmly compacted, simulate cystidia of Tubulicrinis. The resemblance is enhanced in that fascicles of old specimens become enmeshed in hyphal sheaths. They are fascicles, nevertheless, since when mounted singly, crushed under a coverslip, and crystals removed they are seen to be composed of numerous thick-walled hyphae, with many in the interior tapering gradually to the apices. Basidia are at first cylindrical, but as sterigmata elongate they become somewhat cucurbitiform with inflated bases. Spores are naviculate or clavate-naviculate, with attenuated bases. After being shed, ends of spores often collapse near points of attachment when extremities expand into small bulbs. Spores frequently adhere in fours following discharge from the basidia. In shape they resemble somewhat those of E. typhae and E. interrupta. The species is confined to one host, sole representative of the family Palmae in New Zealand, the Maori name for which is nikau.

Hymenophore pileate, coriaceous, annual, sometimes reviving a second season. Pilei at first orbicular and attached by a narrow umbo with reflexed margins, soon merged laterally to form effused-reflexed linear areas to 12 x 2 cm, sometimes resupinate when loosely attached, reflexed portions with a radius of 1-2 cm, extending laterally for the length of the fructification; pileus surface at first fulvous, remaining so or becoming ferruginous, weathering to grey, banded with concentric zones of different shades of brown, sometimes radiately sulcate, tomentose, hairs often arranged in tufts; pileus margin fibrillose, fulvous, entire or torn; hymenial surface at first fulvous, becoming ferruginous or date-brown, sometimes colliculose, at length deeply creviced in small radiate areas; hymenial margin thinning out, fibrillose, fulvous. Context fulvous, 150-200 µm thick, of closely compacted parallel hyphae; cortex absent; abhymenial hairs arising from context hyphae; skeletal hyphae 3-4 µm diameter, walls 0.5 µm thick, golden yellow; generative hyphae 1.5-2 µm diameter, walls 0.2 µm thick, hyaline. Setal layer to 120 µm deep, composed of 1-3 rows of overlapping setae; setae aculeate, often twisted on their axes, with acute apices, a few domeL shaped, some projecting to 80 µm, 80-110 x 7-10 µm, walls naked, deep reddish-brown, lumena narrow. Hymenial layer to 30 µm deep, a close palisade of basidia, paraphyses, and coloured ends of skeletal hyphae. Basidia subclavate, 20-24 x 4-5 µm, bearing 4 spores; sterigmata arcuate, slender, to 5 µm long. Paraphyses subclavate, 8-14 x 3.5-4.5 µm. Spores broadly elliptical, 5.5-6 x 4-5 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Java, Malaya, Japan, Ceylon, Australia, New Zealand.
HABITAT: Crowded on bark of dead twigs, branches and saplings associated with a white rot.
In microfeatures collections match an authentic Leveille specimen from Java in Kew herbarium. They differ in that pilei are not so well developed and the hymenium becomes deeply creviced when old. The species has been placed under Section II, which contains plants with a well developed context but without a cortex.
Plants at first are orbicular and either resupinate or sessile-umbonate with upturned margins. They soon merge to form linear areas with broad resupinate bases and narrowly reflexed margins. The pileus surface is tomentose, hairs becoming compacted into tufts, and arranged in concentric zones of various shades of brown. Pilei are both concentrically and radiately sulcate, these conditions being reflected in the hymenial surface. At first bright fulvous, colour of the pileus surface changes to ferruginous with fulvous margins, and weathers some shade of grey. Pilei are soft and papery, and may be folded without fracture. The hymenium is at first fulvous, soon becoming date-brown and in New Zealand collections fissured so deeply that the fulvous context becomes exposed. Crevices are often arranged in radiate series not unlike those of some resupinate collections of H. obesa. Setae are narrowly aculeate and naked, some being twisted on their axes. A few are short with rounded domed apices (Fig. 161), similar setae being present in the Leveille specimen.

Context ferruginous, to 500 µm thick, of compact parallel hyphae; cortex absent; abhymenial hairs closely arranged, slightly inflated at apices, brief; skeletal hyphae to 6 µm diameter, walls 0.5 µm thick, ferruginous; generative hyphae 3.5-4 µm diameter, walls 0.2 µm thick, hyaline or tinted yellow. Setal layer to 95 µm deep, composed of 3-5 rows of overlapping crowded setae; setae aculeate or fusiform, some projecting to 20 µm, 25-40 x 5-7 µm, walls naked, reddish-brown, 1-2 µm thick. Hymenial layer to 30 µm deep, a dense palisade of basidia and paraphyses. Basidia cylindrical, 12-18 x 4.5-5 µm, bearing 4 spores; sterigmata erect, to 4 µm long. Paraphyses cylindrical, 8-12 x 3-3.5 µm. Spores elliptical or suballantoid, 4-4.5 x 2.5-3 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: India, South America, West Indies, Australia.
HABITAT: Bark of dead branches; type of rot not seen.
The collection listed has been compared with the type in Kew herbarium and found to agree in most features, differing in that surface hairs are more strongly developed. The species is pileate and, as it is without a cortex, belongs to Section II. It may be recognised by the small setae crowded in three to five overlapping rows, and short abhymenial hairs with slightly inflated apices arising directly from the context.

Context cinnamon, 1-3 mm thick, stratose, of numerous setal layers (3-15) with layers of loosely intertwined hyphae between and a broad tissue of intertwined hyphae at the base; generative hyphae 4-5 µm diameter, walls 0.5-1 µm thick, pallid yellow. Setal layers to 95 µm deep, with somewhat scattered setae overlapping into each context layer; setae acicular, some projecting to 50 µm, 60-90 x 5-7 µm, walls naked, golden brown near the surface, darker in the context, lumena narrow. Hymenial layer to 35 µm deep, a close palisade of scanty basidia, abundant paraphyses, and paraphysate hyphae. Basidia subclavate, 16-20 x 4-5 µm, bearing 4 spores; sterigmata arcuate, slender, to 4 µm long. Paraphyses cylindrical, tinted, 8-14 x 4-4.5 µm. Paraphysate hyphae to 4 µm diameter, most branched, hyaline or tinted yellow. Spores suballantoid, 5-6 x 3-3.5 µm, walls smooth, hyaline, 0.1 µm thick.
>DISTRIBUTION: Europe, North America, New Zealand.
HABITAT: Bark or decorticated wood of dead branches associated with a pocket rot.
Plants bear more setal layers than authentic European specimens examined in Kew herbarium, but agree in other features, such as the cinnamon surface colour, context hyphae branched at a wide angle, stratose context, small suballantoid spores, and absence of a cortex. Paraphysate hyphae may be abundant or scanty, but are always present, in some plants being so freely developed as to give the surface a tomentose appearance.
H. cinnamomea, H. arida, and H. rhabarbarina are related species; for all are without a cortex, possess a monomitic hyphal system, a context composed of similar intertwined hyphae, and similar spores. In such stratose species as H. cinnamomea, H. lignosa, H. tasmanica, and H. vaginata strata are demarked by layers of persistent paraphyses which usually stain with aniline blue. They show that each layer represents a growth period, and afford a useful feature by which stratose species may be separated from those bearing many rows of overlapping setae, such as H. fusca or H. magnahypha.

Paraphyses subclavate, 6-12 x 3-3.5 µm. Spores allantoid, 3-4.5 x 1-1.5 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, New Zealand.
HABITAT: Bark of dead branches associated with a white rot.
Collections agree with authentic European specimens examined in Kew herbarium. The species may be recognised by the areolately creviced often rugulose surface and stout, often distorted or radicate setae with verruculose apices. Spores are allantoid and 3-4.5 x 1-1.5 µm, measurements which agree with European specimens, but are smaller than those published by Burt (1918b, p. 359) for North American material. The surface colour ranges from dusky cinnamon to umber or reddish-brown, and the surface may be colliculose, or when examined under a lens, finely rugulose and velutinate. Setae vary appreciably in shape and size, and of those embedded in tissues of the context some may be geniculated, inserted laterally, or strongly radicate. A few exhibit one or more false septa, accidental bridges across the wide lumena.

Hymenochaete corticolor Berk. & Ravenel 1873
FAGACEAE. Nothofagus fusca: Otago, Routeburn Valley, 450 m.
Hymenophore subpileate when umbonate-sessile, or resupinate, probably perennial, woody coriaceous, loosely attached, forming irregularly orbicular colonies 2-10 mm diameter, or merging to form linear areas 2-3 x 1-2.5 cm; pilei reduced to thickened upper edges of specimens growing vertically, naked, black, longitudinally striate, 1-1.5 mm thick; hymenial surface pallid ferruginous, or cinnamon, not creviced, even; margin usually abrupt, sometimes thinning out, crenate, concolorous, free. Context ferruginous, black next the substratum, 0.3-1 mm thick, of mainly erect hyphae embedding scattered setae and numerous large crystals; skeletal hyphae 3-4 µm diameter, walls to 1 µm thick, golden brown; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, hyaline. Setal layer occupying the entire fructification, of numerous overlapping rows of setae sometimes arranged in irregular strata; setae subulate, some projecting to 60 µm, 65-95 x 9-12 µm, walls naked or encrusted, ferruginous, lumena narrow. Hymenial layer to 35 p deep, a close palisade of basidia and paraphyses. Basidia subclavate, 14-22 x 3.5-4 µm, bearing 2-4 spores; sterigmata slightly arcuate, slender, to 6 µm long. Paraphyses cylindrical, 8-15 x 2.5-3 µm. Spores suballantoid, 5-6.5 x 2-2.5 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: North America, West Indies, New Zealand.
HABITAT: Living trunks associated with a pocket rot.
The collection listed agrees with authentic specimens examined in Kew herbarium as to macrofeatures and size, the shape and distribution of setae, and size and shape of spores. It differs in that specimens were collected on dead wood of an axe blaze on a living trunk, whereas North American plants grow upon bark of living trunks.
The species is difficult to place within a key; for fructifications, although often resupinate, are not uncommonly umbonate-sessile with the upper margin (of those growing on upright trunks) thickened into a black glabrous pileus. The context is composed of erect hyphae embedding setae arranged in overlapping rows, sometimes in strata; and, as setae are present throughout the fructification a context, present in most pileate species, is wanting. The plant therefore belongs to Section III, and has been treated as a stratose species with rudimentary pilei. Scattered through the context are numerous coarse crystals, or cavities in which they once were present. Projecting setae are usually encrusted with crystals, and sometimes enmeshed in hyphal sheaths.

Hymenochaete dura Berk. & M.A. Curtis 1868 [1869]
CUNONIACEAE. Weinmannia racemosa: Westland, Weheka, 200 m. MIMOSACEAE. Acacia dealbata: Victoria, Kallista, Dandenong Ranges. ROSACEAE. Rubus schmidelioides: Otago, Horseshoe Bay, Stewart Island.
Hymenophore annual, membranous, umbonate-sessile, or resupinate, loosely attached save at the umbo, effused, appearing as numerous small orbicular colonies 3-10 mm diameter, which may merge peripherally to form irregular areas to 3.5 cm long; hymenial surface bay, tan, chestnut, or ferruginous, sometimes velutinate or fibrillose, not creviced but often slightly compressed in the centre; margin thinning out, concolorous, somewhat lighter in colour in young specimens, fibrillose, loosely attached, sometimes bluntly rounded. Context ferruginous, 0.2-0.45 mm thick, of radiately arranged mainly parallel hyphae, cortex dense, chestnut, bearing numerous abhymenial hairs; skeletal hyphae 3-4 µm diameter, walls 0.5 µm thick, pallid yellow-brown; generative hyphae 2-2.5 µm diameter, walls 0.25 µm thick, hyaline. Setal layer to 80 µm deep, a narrow area of 1-3 overlapping rows of somewhat sparse setae irregularly inserted; setae irregularly fusiform or cylindrical with bluntly acuminate apices, often curved or bent, some projecting to 30 µm, 30-60 x 5-8 µm, walls sometimes verruculose near apices, yellow or pallid chestnut, with broad or narrow lumena. Hymenial layer to 30 µm deep, a somewhat sparse palisade of basidia, paraphyses, and paraphysate hyphae. Basidia subclavate, 12-16 x 3-4 µm, bearing 2-4 spores; sterigmata slightly arcuate, slender, to 4 µm long. Paraphyses cylindrical, 8-12 x 3-3.5 µm. Paraphysate hyphae sparse or abundant, filiform, usually hyaline, projecting to 20 µm. Spores elliptical, 4 x 2 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Cuba, Australia, New Zealand.
HABITAT: Bark of dead erect stems associated with a white rot.
Collections agree with the type of H. dura in Kew herbarium, ex "Cuba, C. Wright, No. 241", differing in the thinner context and slightly narrower skeletal hyphae. Setae resemble those of the type, and are unusual in their irregular shape, bluntly acuminate apices, and presence of occasional false septa. Numerous filiform paraphysate hyphae project and give to the hymenial surface its fibrillose appearance, a condition also present in the type.
Spores were not found in the type. Burt (1918b, p. 353) gave measurements as 5 x 3 µm for a cotype specimen he examined. In collections from this region they are scanty, for although basidia were present in some 20 sections examined, attached spores were seen only in two. These were narrowly elliptical, 4 x 2 µm. Setae were sparse in portion of the type examined. In collections listed they were found to be sparse or abundant, being crowded in the central part, progressively more scanty towards the periphery. Burt (1918b, p. 352) described, paraphysate hyphae as paraphyses; the latter are, however, narrower and shorter than the basidia and do not project.

Hymenophore resupinate, annual, membranous, adherent, at first appearing as small orbicular scattered colonies 0.5-2 cm across, merging to form irregular linear areas 5-15 x 2-6 cm; hymenial surface reddish-brown, often with a purple tinge or purplish when old, even or irregularly roughened, finely velutinate, either without crevices, tardily creviced, or in old specimens sometimes exhibiting radiate series of crevices as in H. obesa; margin thinning out, fibrillose, loosely attached, narrow or broad, fulvous. Context ferruginous, 150-250 µm thick, of mainly parallel hyphae rather loosely arranged, cortex of cemented intertwined hyphae bearing abhymenial hairs of irregular length; skeletal hyphae 4-5 µm diameter, walls 0.5-1 µm thick, golden yellow; generative hyphae 2-2.5 µm diameter, walls 0.25 µm thick, hyaline. Setal layer 80-130 µm deep, of 2-5 crowded overlapping rows of setae embedded among erect skeletal hyphae and of one or two rows of larger, scattered and often distorted setae in the context; setae irregularly fusiform, a few subulate, some projecting to 40 µm, 40-70 x 6-10 µm (some in the context to 85 µm long), walls delicately verruculose at apices, rich chestnut with moderately narrow lumena. Hymenial layer to 25 µm deep, a close palisade of basidia and paraphyses. Basidia subclavate, 12-15 x 3-4 µm, bearing 2-4 spores; sterigmata slender, slightly arcuate, to 5 µm long. Paraphyses cylindrical, 8-12 x 3-4 µm. Spores allantoid, 4-5 x 1 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Ceylon, Australia, New Zealand.
HABITAT: Bark of dead branches and trunks associated with a white rot.
Collections agree in microfeatures with the type in Kew herbarium, ex "Central Provinces, Thwaites, No. 336". Many differ in being less brightly coloured, a feature without taxonomic significance. The species may be separated from others of this section by the small allantoid spores; small setae crowded into several overlapping rows, reddish-brown colour of the hymenial surface and fulvous margin. It is liable to confusion with H. plurimaesetae, differing in features discussed under the latter. Sometimes the cortex is suppressed where tissues are in contact with the substratum; but sections from the free peripheral region demonstrate its presence. Most collections were taken from upright dead trunks and saplings, when the upper margins become thickened to simulate rudimentary pilei.

Hymenochaete fusca (P. Karst.) Sacc. & P. Syd. 1899
CONIFERAE. Podocarpus halli: Taranaki, Mt. Egmont, 950 m. Wellington, Mt. Hauhangatahi, 1,100 m.
Hymenophore resupinate, annual, membranous, adherent, at first appearing as numerous scattered orbicular colonies 3-10 mm diameter, merging to form effused linear areas 4-7 x 1.5-2 cm; hymenial surface sepia, umber, or reddish-brown, colliculose, at length deeply irregularly creviced; margin thinning out, crenate, chestnut when young, becoming concolorous, adherent. Context sepia or fuliginous, 150-250 µm thick, of numerous rows of overlapping setae embedded among erect hyphae, with a delicate layer of intertwined hyphae (sometimes wanting) on the abhymenial surface; skeletal hyphae 3-3.5 µm diameter, walls 0.5 µm thick, yellow brown; generative hyphae 2-2.5 µm diameter, walls 0.1 µm thick, hyaline. Setae subulate with acute apices, some projecting to 50 µm, 65-90 x 7-9 µm, walls naked, reddish-brown, lumena narrow. Hymenial layer to 35 µm deep, a close palisade of basidia and paraphyses. Basidia subclavate, 14-18 x 3.5-4 µm, bearing 4 spores; sterigmata slightly arcuate, slender, to 5 µm long. Paraphyses subclavate, 6-12 x 3.5-4 µm. Spores oval or obovate, a few laterally apiculate, 5-6.5 x 3.5-4 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Europe, North America, West Indies, New Zealand.
HABITAT: Decorticated wood of dead trunks associated with a white rot.
In shape, size, and arrangement of setae, size and shape of spores, and colour of the hymenial surface the species resembles H. fuliginosa. It differs in that fructifications are resupinate, and a cortex and well developed context are absent. The species may be recognised by the acute, naked setae arranged in a setal layer of from three to five overlapping rows occupying the region of the context, oval or obovate spores, and usually small orbicular colonies with dark hymenial surface.
Collections agree with a specimen examined in Kew herbarium ex "Tyrol, V. Litschauer", filed under the cover of H. fuliginosa (Lev.) Bres. This combination was used by Burt (1918b, p. 365) but is untenable since it is occupied by H. fuliginosa (Pers.) Lev., which, according to Bresadola, is a different plant. Burt suggested the correct name for the species is H. fusca, since he found Swedish specimens named by Karsten to agree with H. fuliginosa (Lev.) Bres.

Hymenophore resupinate, annual, reviving a second season, membranous, adherent, effused forming linear areas to 30 x 1-1.5 cm; hymenial surface dark reddish-brown with a purple tinge, velutinate, even, becoming deeply areolately creviced; margin thinning out, definite, fibrillose, ferruginous, adherent. Context 150-250 µm deep, umber, of loosely intertwined and parallel hyphae, bordered by a pseudoparenchymatous cortex bearing short abhymenial hairs; generative hyphae 3-3.5 µm diameter, walls 0.25-0.5 µm thick, golden-brown. Setal layer to 130 µm deep, of scattered fascicles of 2-6 setae with single setae between, arising from the subhymenium; setae subulate, apices acute, some projecting to 60 µm, 40-95 x 6-8 µm, walls naked, deep reddish-brown, lumena narrow. Hymenial layer to 50 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate or more often cucurbitiform, 12-16 x 4-5 µm, bearing 4 spores; sterigmata arcuate, slender, to 6 µm long. Paraphyses subclavate, 10-12 x 5-6 µm. Spores elliptical, or obovate, apiculate, 5-6 x 3-3.5 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Ceylon, New Zealand.
HABITAT: Bark of dead stems associated with a white rot.
Specimens agree with a cotype collection from Ceylon in Kew herbarium, differing in that hyphae are of slightly greater diameter and fascicles more scattered. Fructifications extend for 30 cm upon dead stems, are closely adherent, with even surfaces coloured dark reddish-brown with a purple tinge. The margin is concolorous and fibrillose. Setae are sometimes arranged in slightly projecting fascicles of two to six with solitary setae between; or may appear in a narrow setal layer without evident fascicles. About half the basidia are cucurbitiform, the others subclavate and narrower than the paraphyses. Spores are abundant, commonly elliptical or some slightly obovate with lateral apiculi. Three species with fasciculate setae have been described. H. lictor differs from H. dictator by several features discussed under the latter; and the South African H. fasciculata Talbot differs from both in its larger setae arranged in fascicles of eight to twelve, stratose context, and dendriform generative hyphae.

Hymenochaete resupinate, annual or biennial, membranous, adherent, effused, at first in the form of small orbicular colonies to 5 mm diameter, merging to form linear areas 10-35 x 2-5 cm; hymenial surface when fresh India-red with a brighter periphery, becoming reddish-purple or testaceous, even or tuberculate, at length deeply irregularly creviced; margin thinning out, adherent, bright red with a narrow white or tinted fibrillose edge. Context testaceous or umber, 150-400 µm thick, of parallel hyphae loosely arranged, cortex narrow, with or without abhymenial hairs; skeletal hyphae 3-4 µm diameter, walls 0.5 µm thick, reddish-brown, freely branched, sometimes crystal encrusted; generative hyphae 2-2.5 µm diameter, walls 0.25 µm thick, hyaline. Setal layer 100-150 µm deep, in old specimens to 300 µm, of 3-5 irregular overlapping rows of setae and freely branched hyphae; setae narrowly fusiform, with acuminate apices, some projecting to 50 p, 60-95 x 8-12 µm, walls verruculose, reddish-brown, many tinted only, lumena at first broad, becoming narrow. Hymenial layer to 30 µm deep, a dense palisade of basidia, paraphyses, and paraphysate hyphae. Basidia subclavate, 16-22 x 3.5-4 µm, bearing 4 spores; sterigmata arcuate, slender, to 6 µm long. Paraphyses subclavate, 12-18 x 3.5-4 µm. Paraphysate hyphae projecting, dendriform, coloured or hyaline. Spores suballantoid, apiculate, 6-8 x 3-3.5 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Europe, Great Britain, Australia, Tasmania, New Zealand.
HABITAT: Bark and decorticated wood of dead branches and stems associated with a white rot.
Fresh specimens may be recognised readily by the closely adherent resupinate fructifications with the hymenial surface coloured scarlet or India-red, periphery bright red, and margin white and fibrillose. At first plants are small and orbicular; soon they merge to form irregular linear areas 5-10 cm long, sometimes extending to 35 cm. Sections through actively growing plants show them to be composed of a narrow setal layer of two or three overlapping rows of setae embedded among erect hyphae freely branched, and a context of parallel hyphae bordered by a coloured cortex of intertwined cemented hyphae which may or may not bear abhymenial hairs. In older specimens the setal layer may occupy the greater part of the context, and be composed of as many as 15 rows of setae irregularly distributed. Numerous dendriform paraphysate hyphae project above the hymenial surface especially in the periphery of actively growing plants. They may be coloured or hyaline, are formed from skeletal hyphae, and tend to disappear as plants age. In the context skeletal hyphae are scantily branched, but in the setal layer become freely so, almost dendriform. Spores, usually suballantoid, may be cylindrical with rounded ends.
Collections listed differ from typical European plants in several particulars. They are more deeply coloured, with purple shades rather than scarlet, margins are less brightly coloured, more closely attached to the substratum, and abhymenial hairs are usually scantily developed save in young specimens. In microfeatures they are similar, even to the dendriform paraphysate hyphae. The distribution given is based on examination of specimens in Kew herbarium and received from correspondents.

Hymenophore pileate or umbonate-sessile, sometimes reviving a second season, coriaceous, rigid, loosely attached, appearing as effused-reflexed or orbicular colonies 5-25 mm diameter, often laterally merged to form linear areas which may extend to 15 cm. Pilei effused-reflexed with broad resupinate areas and narrow reflexed margins to 10 mm wide, when resupinate disciform with free margins; pileus surface delicately tomentose, sometimes radiately sulcate, ferruginous or umber, darkening with age; hymenial surface bistre or chocolate with a reddish tinge, colliculose, deeply scantily creviced when old, velutinate; margin thinning out, bright fulvous, loosely attached. Context dark ferruginous or umber, 0.3-0.6 mm thick, of parallel hyphae radiately arranged, erect in the setal layer, and bordered on the abhymenial surface by a deeply coloured cemented cortex of intertwined hyphae; skeletal hyphae 2.5-3 µm diameter, walls 0.5 µm thick, golden brown; generative hyphae 2-2.5 µm diameter, walls 0.2 µm thick, hyaline. Setal layer 120-250 µm deep, a compact zone of 3-7 overlapping rows of setae embedded among erect skeletal hyphae; setae projecting to 90 µm, aculeate, some slightly curved, 80-105 x 7-9 µm, walls naked, rich chestnut, lumena narrow. Hymenial layer to 40 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 20-24 x 4-5 µm, bearing 4 spores; sterigmata arcuate, slender, to 4 µm long. Paraphyses subclavate, 8-18 x 3.5-4 µm. Spores oblong-elliptical, 5.5-7 x 3.5-4 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, New Zealand.
HABITAT: Bark of dead branches and trunks associated with a pocket rot.
Although resembling H. tabacina in the presence of a coloured cortex, dense setal layer, and effused-reflexed fructifications the species differs in that spores are elliptical, setae are narrower, darker in colour, naked, only one colour zone, the cortex, is present, and fructifications are of different shape and colour. Collections vary appreciably. Most are either umbonate-sessile, when orbicular with margins plane, or narrowly effused-reflexed and linear. The pileus surface is some shade of brown, becoming darker with age, in some old specimens being almost black. The hymenial surface of fresh specimens is bright reddish-brown, with bright fulvous margins. On drying, or in old specimens, the surface may change to dingy umber or fuscous and margins become concolorous. Appreciable variations also occur in depth of the setal layer and consequently the number of overlapping rows of setae, thickness of the context, and abundance of abhymenial hairs. In microfeatures New Zealand plants agree with European specimens examined, which also exhibit similar variations in these features. They differ chiefly in host range, all being taken from conifers, whereas in Europe and North America the species is usually found upon frondose species. Although recorded by earlier workers from Australia and Tasmania, collections so named in Kew herbarium are of other species.

Hymenophore resupinate, annual, sometimes perennial, membranous-brittle, adherent, effused forming irregular areas 3-6 x 2-3 cm; hymenial surface seal-brown, dark umber, or chocolate, irregularly tuberculate, velutinate, not or tardily creviced; margin thinning out, cinnamon, fibrillose, loosely attached. Context dark umber or sepia, 150-300 µm thick (to 800 µm in stratose specimens), sometimes vertically fibrillose where fractured, of mainly erect hyphae and a cortex of parallel cemented hyphae deeply coloured and bearing abhymenial hairs of irregular length; generative hyphae 4-5 µm diameter, walls 0.5-1 µm thick, dark yellow-brown, some submoniliform. Setal layer to 250 µm deep, composed of 2-5 overlapping rows of setae and stout erect hyphae; setae irregularly fusiform, some projecting to 45 µm, apices acute, 40-70 x 8-12 µm, walls naked, rich chestnut, lumena narrow. Hymenial layer to 30 µm deep, a close palisade of basidia, paraphyses, and paraphysate hyphae. Basidia subclavate, 12-16 x 3.5-4 µm, bearing 4 spores; sterigmata slender, erect, to 4 µm long. Paraphyses cylindrical, 18-24 x 4-5 µm, walls tinted yellow. Paraphysate hyphae scanty, projecting to 30 µm, cylindrical, many submoniliform. Spores suballantoid, 3.5-4 x 1-1.25 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Ceylon, South Africa, Australia, New Zealand.
HABITAT: Decorticated wood of dead branches and trunks associated with a pocket rot.
Collections agree with the type, part of which was examined in Kew herbarium. The species may be identified by several unusual microfeatures, as the occasional submoniliform hyphae which, together with normal hyphae, appear in the context, abhymenial hairs, and as paraphysate hyphae; erect hyphae of the context; presence of a stout cortex of parallel hyphae; delicate basidia and the monomitic hyphal system. Some of these features vary appreciably in different collections. In the type the context consists of a compact dense layer of parallel hyphae, the cortex, and erect hyphae forming a loose palisade between this and the setal layer. About one-third of the hyphae are submoniliform, a feature not mentioned by Petch. In one New Zealand collection in which plants are somewhat immature, a dense cortex is present, and the setal layer arises directly from this with, between setae, erect palisade hyphae, a few of which are submoniliform. In other New Zealand collections the context is stratose, consisting of several setal layers with hyphae between. The latter are erect as in the type, and a few exhibit submoniliform areas as is shown in fig. 152. Basidia and spores were not described by Petch, nor found by Talbot (1951, p. 49). They are nevertheless present in the type and all New Zealand collections. Basidia are delicate, scanty, and smaller than the cylindrical coloured paraphyses.

Hymenophore pileate or resupinate, sometimes reviving a second season, membranous-coriaceous, loosely attached. Pilei either conchate when attached by an umbo, dimidiate, or more frequently effused-reflexed with pilei arising from margins of broadly resupinate bases, 1-25 x 1-5 cm, when resupinate linear or disciform with free margins, of indefinite length; pileus surface some shade of brown, lighter peripherally with fulvous margins, radiately sulcate, finely tomentose, sometimes when old naked and dingy fuscous; hymenial surface commonly tobacco-brown, with bright fulvous margins, velutinate, oµmen with a chestnut tinge, resupinate portions often deeply creviced in radiate series about 10 mm diameter, sometimes creviced irregularly, or even; margin thinning out, lighter in colour, crenate, free. Context ferruginous, 0.3-0.6 mm thick, of parallel hyphae radiately arranged, bordered on the abhymenial surface by a darker, compact and cemented cortex, and beneath the hymenium by a darker chestnut zone associated with the setal layer; skeletal hyphae 4-5 µm diameter, walls 0.5-1 µm thick, golden brown; generative hyphae 2-2.5 µm diameter, walls 0.2 µm thick, hyaline. Setal layer 160-300 µm deep, composed of 3-5 overlapping rows of setae some of which project to 90 µm; setae aculeate, 80-130 x 14-22 µm, walls finely verruculose, chestnut, lumena narrow. Hymenial layer to 40 µm deep, a close palisade of basidia and paraphyses. Basidia subclavate, 12-20 x 4-5 µm, bearing 4 spores; sterigmata erect, slender, to 4 µm long. Paraphyses subclavate, 10-14 x 3.5-4 µm. Spores allantoid, 6-8 x 1.5-2 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Great Britain, Europe, North America, Australia, New Zealand.
HABITAT: Bark of dead branches associated with a white rot.

One of the most abundant species present in New Zealand, but rare in Australia, H. tabacina may be identified by the following features. Plants are either effused-reflexed, sessile with free margins of lighter colour, or as frequently resupinate. A deeply coloured cortex borders the abhymenial surface and a second colour zone lies beneath the hymenium, sometimes extending into the setal layer. From the cortex abhymenial hairs arise both in pileate and resupinate specimens, consequently plants are loosely attached to the substratum. The setal layer is more deeply coloured than the context, and the number of rows of setae increases with age, or position, being more numerous towards the centre and thinning out towards margins, where but one or two rows may be developed. Setae are stout, rich reddish-brown, with verruculose apices. Spores are allantoid, abundant and borne upon short sterigmata.
Colour and thickness of fructifications appear to be influenced by latitude and altitude. Plants from this region, save from the mountains, are more coriaceous and of deeper colour than typical specimens from the northern latitudes of Europe and North America. Commonly tobacco-brown, New Zealand plants often exhibit a reddish-brown colour when viewed at an angle under a lens, because of projecting setae. Many may develop a second growth form upon an earlier fructification. They agree with European specimens in microfeatures, although even these may vary appreciably. In some resupinate specimens the hymenial surface is creviced in orbicular series, each about one centimetre in diameter, crevices radiating from the centre. The condition is more common in European and North American collections than in those from this region. It is not confined to this species, but occurs also in some specimens of H. floridea and all plants of H. obesa.

Hymenophore resupinate, perennial, stratose, membranous, adherent, at first appearing as numerous small orbicular or linear colonies 2-10 mm across with free, fulvous, fibrillose margins, merging to form irregular areas to 10 x 5 cm; hymenial surface at first reddish-brown, becoming ferruginous or pallid umber, commonly coarsely and densely tuberculate, sometimes even when slightly velutinate, not creviced; margin fulvous, or concolorous, adherent, fibrillose. Context ferruginous, 0.25-4 mm thick, in annual plants composed of one or two rows of rather scanty setae arising near the hymenial surface, a broad layer of intertwined usually dendriform hyphae and a narrow, reddish-brown, compact cortex bearing dense, brief abhymenial hairs; when perennial stratose with 5-16 layers of setae with context hyphae between and parallel lines of darker colour; generative hyphae 2-2.5 µm diameter, walls 0.5-1 µm thick, golden brown, freely branched, with many short lateral branches, scantily septate. Setal layers 95-130 µm deep, of 5-16 zones with context tissue between; setae acicular, apices long-acuminate, some projecting to 70 µm, 70-130 x 8-12 µm, walls naked, reddish-brown, lumena narrow, expanded towards the bases. Hymenial layer a close palisade of basidia, paraphyses, and paraphysate hyphae. Basidia subclavate, 14-18 x 4.5-5 µm, bearing 2-4 spores; sterigmata slender, erect, to 5 µm long. Paraphyses subclavate, 6-12 x 4-4.5 µm. Paraphysate hyphae dendriform, projecting, brown. Spores suballantoid, apiculate, 4-5.5 x 3-3.5 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Australia, Tasmania, New Zealand.
HABITAT: Bark or decorticated wood of dead branches and trunks associated with a pocket rot.
H. tasmanica may be identified by the usually coarsely tuberculate, ferruginous hymenial surface, fulvous margin of young plants, long and narrow, reddish-brown setae usually arranged in strata, thick-walled narrow hyphae which are freely branched, brown dendriform paraphysate hyphae, and suballantoid spores. The hymenial surface of Australian collections is less tuberculate than those from New Zealand, but in other particulars they are almost identical. Setae are slightly longer in smooth forms, but show an appreciable range in length in all specimens. Spores are scantily produced and found only in specimens actively growing at the time of collecting. Figure 157 was drawn from a young plant showing only two setal layers; in thick specimens as many as 16 layers may develop to occupy the greater part of the context.
Massee's description of the type is faulty in several particulars; for setae are much shorter than he had described them, and spores are shorter and suballantoid. The type specimen was collected in Tasmania, as the type sheet shows, not New Zealand as he had recorded. H. vaginata differs in that setae are of different shape, larger, and usually enmeshed in hyphal sheaths; hyphae are not dendriform, paraphysate hyphae are simple, spores longer and of different shape. Both H. tasmanica and H. vaginata show a general resemblance to H. cinnamomea, since all three are stratose and composed of branched generative hyphae. They differ in possessing a deeply coloured cortex of intertwined and cemented hyphae.

PALMAE. Rhopalostylis sapida: Auckland, Whitianga Road, Coromandel Peninsula, 250 m. UNKNOWN HOST. New South Wales, Sydney.
Hymenophore resupinate, perennial, membranous, brittle, adherent, at first appearing as numerous orbicular colonies 2-15 mm across, soon merging to form linear areas to 12 x 3 cm; hymenial surface cinnamon, deeply irregularly areolately creviced, tending to lift at edges of crevices; margin thinning out, fulvous, fibrillose, adherent. Context ferruginous, 400-650 µm thick, of many irregular rows of overlapping setae embedded among erect, closely compacted hyphae, sometimes with a narrow zone of intertwined hyphae of deeper colour in the base of the abhymenial region; generative hyphae 3-4 µm diameter, walls 0.5 µm thick, yellow brown. Setae scattered in irregular rows through the context, subulate, some projecting to 35 µm, 40-60 x 5-7 µm, walls naked, reddish-brown, lumena narrow. Hymenial layer to 30 µm deep, a close palisade of basidia, paraphyses, and paraphysate hyphae. Basidia subclavate, 12-16 x 4-5 µm, bearing 4 spores; sterigmata slightly arcuate, slender, to 5 µm long. Paraphyses subclavate or cylindrical, 6-10 x 3.5-4 µm. Paraphysate hyphae abundant or scanty, projecting to 25 µm, filiform, hyaline. Spores elliptical, 4.5-5.5 x 3-3.5 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: West Indies, South America, Australia, New Zealand.
HABITAT: Bark or decorticated wood of dead branches or leaf bases associated with a pocket rot.
In microfeatures specimens agree with the type collection in Kew herbarium, ex "Cuba, Wright, No. 541". They differ somewhat in size and colour of fructifications. The context is composed of overlapping rows of setae embedded among compact erect hyphae, with the abhymenial layer of intertwined hyphae more deeply coloured and compacted. Colour of the hymenial surface resembles that of H. cinnamomea and H. rhabarbarina. From these H. unicolor differs in that setae are slightly shorter and arranged in overlapping rows and, although stratose, layers are indicated by dark parallel lines and not by zones of context hyphae. Spores also differ in shape.

HABITAT: Bark or decorticated wood of dead branches and stems associated with a coarse pocket rot.
Resembling Stereum illudens in general appearance, the species may be identified readily since it is the only Hymenochaete present in the region with applanate or flabelliform pilei. The pileus surface is coarsely tomentose, concentrically sulcate and zoned with hairs of different shades of brown, radiately sulcate, and sometimes plicate. In young plants the tomentum is usually aggregated into strigose tufts, but as plants age, hyphae become lax and intertwined to form a dense mat which may attain a depth of 0.5 mm. Finally the tomentum tends to disappear, weathered plants sometimes becoming naked and almost black. The hymenial surface reflects the configuration of the pileus surface and exhibits a wide range of colours. At first ferruginous, it soon becomes date-brown, often with a plum-coloured bloom, and finally dark umber. Under a lens, sections appear dark brown and glistening. The context is composed of stout parallel hyphae, closely compacted and cemented, with a darker cortex formed from parallel hyphae and bearing the abhymenial hairs. The setal layer is narrow and composed of two or three overlapping rows of small setae embedded among irregular erect hyphae. Setae are subulate with often a stout base turned at an angle and parallel with the context hyphae. Spores are scanty and found only near margins of growing plants.
Choice of a specific name lies between H. villosa and H. nigricans. Both were published (as Stereum) on the same page by Leveille. Bresadola claimed they were applied to the same species, but this I have not been able to verify since the types have not been examined. Collections match an authentic Leveille specimen of Stereum villosum in Kew herbarium; and Petch forwarded specimens to Kew herbarium from Ceylon, named H. nigricans, which are of the same species. The combination Hymenochaete villosa was published by Bresadola six years before he used H. nigricans; and as the latter is inappropriate, save for old weathered plants, I have preferred H. villosa, a combination also used by Wakefield (1915, p. 368) for an Australian collection in Kew herbarium.
Distribution is based on collections examined in Kew herbarium, filed under H. nigricans, H. phaea (type ex Bay of Islands, N.Z.), H. spadicea (type ex Ceylon), H. strigosa (type ex Ceylon), and H. villosa. Three collections from Tasmania in Kew herbarium are filed under H. rubiginosa.

Although close to L. villosa in macrofeatures, the species may be separated by the larger basidia and almost triangular spores with rounded angles and oblique apiculi. Only a few spores exhibit this feature, others being obovate, pyriform, or limoniform, often with two apiculi. In the original description the hymenial surface was said to be violaceous, but in collections examined in Kew herbarium, and those present in this region, it is cream or buff.

In a former paper I (1953b, p. 178) described the species under the name of Solenia stipitata. W. B. Cooke has advised that this is a synonym of S. anomala. The species may be recognised by the brown, irregularly shaped pilei, and tomentose exterior clothed with filiform, brown, encrusted abhymenial hairs with inturned or hooked apices some of which are apically inflated. Sometimes a second pileus develops from the interior of an older one, plants then being twice or thrice as long. The subiculum may be scanty and arachnoid, or well developed, approaching membranous. The species was made the type of Cyphellopsis Donk and, because of the well developed subiculum and brown hyphae, could well be employed as the type of a small genus to contain L. anomala and other species with these features.

Subiculum annual, arachnoid, white, effused forming areas to 10 cm across. Pilei densely aggregated, sometimes confluent, seldom scattered, cylindrical or subclavate, 0.5-3 mm tall, 0.1 -0.4 mm diameter, attached by narrow bases, ceraceous, brittle, white drying honey yellow; pileus surface covered with tortuous encrusted (in part) abhymenial hairs; margin even, inrolled and slightly thickened. Context white, to 35 µm thick, of densely compacted parallel hyphae; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, hyaline. Hymenial layer to 30 µm deep, a close palisade of basidia and paraphyses. Basidia clavate, 12-16 x 5-6 µm, bearing 4 spores; sterigmata erect, slender, to 4 µm long. Paraphyses subclavate, 10-14 x 4-5 µm. Spores subglobose, a few globose or oval, 4.5-5.5 µm diameter, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Europe, Great Britain, North and South America, Australia, New Zealand.
HABITAT: Crowded often in fascicles on bark or decorticated dead branches or dead stipes of tree ferns.
Pilei grow in dense clusters, rarely solitary. At first globose, they soon become cylindrical. The exterior is covered with tortuous, aseptate, simple abhymenial hairs which later may disappear though some may remain near apices. The subiculum is arachnoid, delicate and often difficult to detect unless specimens are examined under a dissecting microscope. Spores vary in size and shape; when first formed, walls are relatively thick, but as spores mature walls become thinner. In a previous paper (1953b, p. 176) I listed "Solenia" fasciculata as a synonym of S. candida . W. B. Cooke has advised that the two may be separated by the abhymenial hairs, those of the former being filiform and encrusted, of S. candida delicate, naked, and branched near apices. In other particulars they appear to be similar, save that pilei of L. candida are seldom crowded into fascicles.

SCROPHULARIACEAE. Hebe salicifolia: Taranaki, Mt. Egmont, 1,350 m, type collection, P.D.D. herbarium, No. 11167.
Pilei annual, scattered, membranous-coriaceous, cupulate, 1-2.5 mm diameter, attached by narrow bases; exterior bay, tan, or ferruginous, finely radiately striate, often splitting on the posterior side, usually naked, rarely with a few scattered hairs; margin acute, slightly inturned, entire or with one or two deep incisions; hymenial surface concave, even, pallid cream. Context white, save for a few tinted hyphae near the periphery, to 80 µ thick, of radiately arranged densely compacted parallel hyphae; generative hyphae 4-5 µ diameter, walls to 2 µ thick, hyaline. Hymenial layer to 40 µ deep, a close palisade of basidia and paraphyses. Basidia subclavate, 35-42 x 10-12 µ, bearing 4 spores, sterigmata arcuate, slender, to 6 µ long. Paraphyses subclavate, 28-36 x 6-8 µ. Spores elliptic-fusiform, a few suballantoid, ends bluntly acuminate, apiculate, 12-13 x 4-5 µ, walls smooth, hyaline, 0.2 µ thick.

HABITAT: Scattered on bark of dead twigs.
Lachnella hebe and L. totara resemble one another in shape and colour of the naked pilei. They differ in several microfeatures, mainly in structure of the context and shape of the spores. Exterior walls of occasional pilei appear as if delicately tomentose when examined under a dissecting microscope, an appearance produced by brief ends of occasional context hyphae which project slightly.
Lachnella muscigena sensu G. Cunn. 1963
UNKNOWN MOSS HOSTS. Wellington, Silverstream. South Australia, Adelaide.
Pilei annual, scattered, ceraceous, fragile, 0.2-3 mm diameter, campanulate, often irregular, attached by or pendent from brief bases arising from white fibrillose discs; exterior white, drying white or pallid cream, naked or at first delicately tomentose with hyphal ends of context hyphae; margin acute, plane or flaring, often deeply lacerated; hymenial surface even or slightly rugulose, white. Context white, to 100 µm thick, of radiately arranged densely compacted hyphae; generative hyphae to 8 N. diameter, commonly about 5 µm, walls 0.25 µm thick, hyaline. Hymenial layer to 40 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 16-24 x 5-6 µm, bearing 2-4 spores; sterigmata erect, slender, to 6 µm long. Paraphyses subclavate, 12-18 x 4-5 µm. Spores pyriform or oval with acuminate bases, apiculate, 7-9 x 5-6 µm, walls smooth, hyaline, 0.25 µm thick.
DISTRIBUTION: Europe, Great Britain, Australia, New Zealand.
HABITAT: Scattered on leaves and stems of mosses.
Plants agree with authentic specimens examined in Kew herbarium. The species may be. recognised by the fragile naked pilei, context hyphae of large diameter, and oval spores with acuminate bases. The moss habitat is also noteworthy. Bourdot & Galzin (1928, p. 158) stated that context, hyphae were without clamp connections; but as they are present in specimens at hand it is possible two species are involved. The hymenial surface is usually even; occasional plants are slightly rugulose, the condition being confined to large specimens. Owing to similarity of specific names, the species might be confused with Cantharellus muscigenus (Bull.) Fr. which has been proposed by Donk (1951, pp. 211, 213) as the type species for Leptoglossum Karst. and Dictyolus Quel.

Abhymenial hairs provide the yellow colour of pilei; they are erect, imbricated, sometimes tortuous, with acuminate apices and yellow walls encrusted with fine crystals. The subiculum is delicate and extends as an arachnoid film beyond the area occupied by the pilei. It is composed of a few repent hyphae from which arise erect tufts of branched and tortuous hyphae with yellow walls.

HABITAT: Scattered on bark of living and dead branches and trunks.
Common on two endemic species of Podocarpus, called totara by the Maori, the species possesses the largest pilei of any present in the region. Usually 1-3 mm diameter, pendulous and conical-cupulate (as in the type collection), pilei sometimes may extend laterally to 8 mm, and become scutellate with a slightly wrinkled hymenial surface. Pilei grow upon bark of living or dead branches and small trunks, and because of the exterior colour are difficult to detect. In Kew herbarium there is a collection, ex "Buller Valley, Westland, T. Kirk, No. 236" which Cooke placed under the cover of `Cyphella' cupulaeformis Berk. & Rav. The latter differs in possessing markedly angular, distorted, irregular spores

Of the three species with monomitic hyphal systems L. areolata may be identified by the delicate hymenophore, small metuloids with brief hyaline pedicels, and absence of clamp connections. The context of pileate specimens consists of a broad layer of mainly parallel hyphae from which arise the abhymenial hairs, bordered by a deep layer of erect hyphae containing the metuloids; in resupinate specimens the context is composed mainly of intertwined hyphae as in members of the Corticeae. Lower metuloids are more coarsely encrusted, crystals becoming progressively finer towards the surface.

UNKNOWN HOST. New South Wales, Moruya (Type collection, herb. Kew).
Hymenophore perennial, coriaceous, resupinate with a dark brown thickened fibrillose border 2-3 mm deep representing the pileus, loosely attached, forming irregular areas to 8 x 7 cm; hymenial surface pallid ochre, even or somewhat radiate-striate, not creviced. Context isabelline or woodbrown, 0.5-0.75 mm thick, of compact parallel hyphae radiately arranged, embedding scattered metuloids, bordered by a coloured cemented cortex to 70 µm thick, from which arise short, stout abhymenial hairs; skeletal hyphae 4-5 µm diameter, walls so thickened that lumena are capillary; generative hyphae 3-3.5 µm diameter, walls 0.1 µm thick, naked, with clamp connections. Metuloids arranged in numerous rows in a layer to 350 µm deep, each in a lacuna formed from intertwined compact staining hyphae, obconic or fusiform with long pedicels staining blue, a few projecting slightly, 24-72 x 10-16 µm,upper two-thirds encrusted with coarse hyaline crystals, naked towards the base, many with pedicels alone remaining. Hymenial layer to 30 µm deep, a dense palisade of basidia, paraphyses, and metuloids. Basidia subclavate, 16-24 x 5-6 µm, bearing 4 spores; sterigmata erect, slender, to 4 µm long. Paraphyses cylindrical, 12-20 x 5-6 µm. Spores globose, or oval, 4.5-5-5 x 4-4.5 µm, walls hyaline, smooth, 0.1 µm thick.
DISTRIBUTION: Australia.
HABITAT: Loosely attached on dead wood.
Although the type specimen is almost resupinate, one margin shows a definite thickening, which represents a rudimentary pileus. Together with the arrangement of the context hyphae, dimitic hyphal system, presence of a well developed coloured cortex, and abhymenial hairs, this indicates that the species possesses the morphology of a pileate Stereum; and the metuloids show it to be a Lopharia. Metuloids are arranged in many rows in a compact zone occupying about one-third to one half of the thickness of sections. Each is seated in a lacuna with the pedicel attached to the floor of the cavity, exactly as in Peniophora sacrata (Fig. 74). Spores are mostly subglobose, a few oval, with delicate walls.

Hymenophore annual or biennial, coriaceous, widely effused with reflexed margins, or resupinate, at first small and orbicular, finally forming irregular areas 7-12 x 1-4 cm. Pilei narrowly applanate, often reduced to mere upturned margins, or wanting; pileus surface straw colour or pallid ochre, clothed with appressed hairs often imbricately arranged, or radiately striate; hymenial surface cream to pallid ochre, sometimes buff, velutinate, at length deeply areolately creviced, or finely tuberculate; margin when resupinate thinning out, fibrillose, concolorous, adherent. Context cream, isabelline, or bay, 0.2-1 mm thick, of parallel hyphae densely arranged, tinted towards the base, bordered by a coloured cortex and abhymenial hairs; skeletal hyphae 4-5 µm diameter, lumena capillary, naked; generative hyphae 2.5-4 µm diameter, walls 0.2 µm thick, without clamp connections. Metuloids arranged in a zone of erect hyphae, each within a locule, some projecting to 90 µm, narrowly conical, or lanceolate, with short, stout, often tinted pedicels, 80-180 x 16-26 µm, coarsely encrusted throughout. Hymenial layer to 70 µm deep, a close palisade of basidia, paraphyses, and metuloids. Basidia subclavate, 40-64 x 8-12 µm, bearing 4 spores; sterigmata arcuate, slender, to 8 µm long. Paraphyses subclavate, 35-56 x 6-10 µm. Spores elliptical with rounded ends, 9-14 x 7-9 µm, walls smooth, hyaline, 0.5 µm thick.
DISTRIBUTION: Cosmopolitan.
HABITAT: Effused on bark or decorticated dead wood.
Separated by the dimitic hyphal system, skeletal hyphae with walls so thickened that lumena are capillary, large metuloids with short and stout pedicels, large basidia and spores. Metuloids may be arranged in one irregular row in the hymenial layer, or more often in several obscure zones within tissues of the hymenial layer and context. They vary appreciably in shape and size, shape and length of the stout pedicels, and size of crystals. Some basal metuloids may be naked, or bear only a few scattered crystals. In thin specimens the context is composed of parallel hyphae as in species of Stereum; in thick forms a deep subhymenium is developed in which metuloids are embedded in lacunae.
The species bears a long list of synonyms, although its specific name has seldom been in doubt. Usually placed under Peniophora, on account of the metuloids, or Stereum because of the pileate fructifications, it has also been used as the type species of Thwaitesiella, Lloydella, and Lopharia. Lloyd admitted that his Stereum purpurascens was merely a coloured form; and Talbot showed that S. caperatum Lloyd and S. turgidum Lloyd were likewise synonyms. S. subporiferum Berk., the 'type' of which came from the Chatham Islands, ex "Travers, No. 7" is also based on the species.

Hymenophore pileate, annual, membranous, effused-reflexed, often resupinate, at first developing as small orbicular colonies merging to form linear areas which may extent to 40 x 4 cm. Pilei laterally extended and narrowly applanate, sometimes imbricate; surface grey or fawn, abhymenial hairs radiately arranged and sometimes concentrically zoned, often imbricated; hymenial surface ranging in colour from cream through buff or ochre to dark umber, often violaceous, heliotrope, or tinted purple, at first even or finely tuberculate, becoming deeply areolately creviced, tending to lift at margins of crevices; margin when resupinate thinning out, fibrillose, concolorous, adherent. Context dingy white, 0.2-1 mm thick, without a cortex, of parallel hyphae and an intermediate layer of ascending hyphae, loosely arranged and embedding metuloid pedicels; generative hyphae 4-6 µm diameter, walls 0.5-1 µm thick, naked, without clamp connections. Metuloids borne on long slender pedicels, extending to the hymenial layer, some projecting to 35 µm and scattered through the context, narrowly fusiform with acute apices, tinted fuscous, 40-190 x 8-16 µm, encrusted with hyaline or tinted crystals which may cover the modified body or be confined to its apical region, occasionally in part encrusted with brown mucilage granules; pedicels of unusual length, some 600 µm long, 5-7 µm diameter, some lightly tinted beneath metuloids. Hymenial layer to 60 µm deep, a loose palisade of basidia, paraphyses, and metuloids. Basidia subclavate, 20-24 x 5-6 µm, bearing 4 spores; sterigmata slender, erect, to 6 µm long. Paraphyses subclavate or cylindrical, 12-18 x 4-5 µm. Spores elliptical, 5-7 x 2.5-3 µm, walls smooth, hyaline, 0.2 µm thick.

HABITAT: Dead bark and decorticated wood.
In a former paper (1956a, p. 625) I employed the combination Lopharia vinosa under the impression that Berkeley's name Thelephora vinosa was the first applied to the species, overlooking that Persoon had earlier (1801, p. 578) used this name for a different plant. Lentz (1955, p. 20) used Laxitextum crassum for the species, deriving the specific name from Thelephora crassa Lev., part of the type of which, ex herb. Bresadola, from Tourane, Cochin China, was in the herbarium of National Fungus Collections of the United States Department of Agriculture. The species varies appreciably in the degree of pileus formation, thickness of context, surface colour, size and abundance of metuloids, length of pedicels, and coarseness of crystals. Most collections are resupinate, or exhibit broad resupinate fructifications with narrow reflexed margins; in others pilei are freely developed and often imbricately arranged. The context may vary in thickness and in old specimens exhibit vaguely defined zones of metuloids and context hyphae. Colour of mature plants may be some shade of brown, umber predominating, or as frequently violaceous, heliotrope, or purple, Australasian collections being rich in brightly coloured specimens. At first white, colour rapidly changes to some shade of brown, or violaceous shades may appear as soon as colour changes begin. Resupinate forms may be separated from species of Peniophora by the tinted metuloids borne on unusually long pedicels which, being aseptate, simulate skeletal hyphae although the species has a monomitic hyphal system. Pedicels ascend obliquely and are sometimes tinted beneath the metuloids. Their length would appear to be governed by development of the context, in thick plants pedicels attaining a maximum length of 600 µm. Occasional crystals are also tinted; they may be abundant or scanty, coarse or fine, and may encrust metuloids completely, be confined to their apical regions, or appear as scattered granules upon their surfaces. Bridging hyphae have been noted in the context.

OLEACEAE. Gymnelaea lanceolata: Auckland, Waitakere Ranges, 300 m. UNKNOWN HOSTS. Queensland, Tully Falls, Atherton Tableland. Fiji, Suva Forestry Station; Upolu.
Hymenophore annual, coriaceous, scattered or crowded, sessile. Pilei commonly flabelliform when attached by a narrow lateral umbonate base, conchate, cupulate or pateriform when attached by a basal umbo, sometimes imbricate, 1.5-7 cm radius, 1-5 cm wide; pileus surface at first velutinate and azonate, soon concentrically banded with zones of coloured hairs which may be bay, chestnut, reddish-brown or even olivaceous, often radiately rugulose or fluted; margin entire, crenate, deeply lobed, or torn, darker in colour, thinning out; hymenial surface reflecting surface irregularities, ranging in colour from cream through ochre to rich reddish-brown, often vernicose and pruinose towards the base. Context white or wood colour with, in mature plants, a thick, waxy, deep, subhymenial zone, 0.3-1 mm thick, a dense layer of mainly parallel hyphae bordered by a narrow cortex bearing abhymenial hairs which may be slightly inflated at their free ends; skeletal hyphae 4-6 µm diameter, walls thickened; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, with clamp connections. Gloeocystidia arising at different depths in the subhymenium, penetrating the hymenial layer but not projecting, flexuous-cylindrical or fusiform, usually somewhat inflated near bases, 60-110 x 6-10 µm. Metuloids arising at various depths in the subhymenium, not projecting, obconic or fusiform with prominent pedicels, 35-56 x 12-16 µm, walls to 4 µm thick, encrusted, pedicels hyaline. Hymenial layer 50-250 µm deep, a dense almost gelatinised layer of basidia, paraphyses, gloeocystidia, and metuloids. Basidia subclavate, 12-18 x 3.5-4 µm, bearing 4 spores; sterigmata erect, slender, to 4 µm long. Paraphyses cylindrical, 12-18 x 2.5-3 µm. Spores elliptical, apiculate, 3-3.5 x 2-2.5 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Mauritius, South Africa, Philippine Islands, Fiji, New Guinea, Cook Islands, Australia, New Zealand.
HABITAT: Solitary or crowded on bark of dead branches and trunks.
Collections agree with the type of 'Thelephora' involuta Kl. in Kew herbarium. Although Fries (1838, p. 546), Massee (1890, p. 176) and Saccardo (1888, p. 560) cited Klotzsch as the author and Linnaea7: 499, 1830 as the place of publication, there is no reference to the species in that or any other volume of Linnaea. His was most likely a herbarium name validated by Fries. Specimens show a wide range of variation in size, shape, surface markings, and colour of the pileus surface and hymenium. Several species were based on slight differences in these, and according to Lloyd (1922, p. 1115) Stereum bresadoleanum Lloyd, S. gossweileri Lloyd, and S. philippense Lloyd were erected on slight differences in colour and markings of the pileus surface. When young, plants are conchate and attached by a lateral or basal umbo and the surface is velutinate without evident zoning. As plants enlarge they mostly change in shape to flabelliform and become concentrically zoned with bands of different shades of brown hairs. According to their age when collected, in these features alone plants may exhibit the minor differences upon which Lloyd's several species were based. The hymenial surface also shows a wide range of colours; at first cream or ochre, in old plants it becomes rich reddish-brown and appears as if varnished. Plants also exhibit variations in numbers, shape, and size of gloeocystidia and metuloids. In old plants they are usually abundant and distributed through the thickened hymenial layer, which exhibits a granular appearance owing to being partly gelatinised with components cemented. There are numerous collections from this region in Kew herbarium, placed under the covers of Stereum involutum, S. moselei, S. prolicans, and S. vespilloneum. S. hollandii Lloyd, ex "Okumi, Cross River Expedition, J. H. Holland, No. 40" is based on an infundibuliform plant, not uncommon in Fijian collections at hand.

From L. crassa the species is separated by the much smaller, distorted and irregular, more coarsely encrusted metuloids, smaller spores, and different colour and texture of the hymenophore. Metuloids show unusual diversity in size and shape, are encrusted on their upper half, naked below, most are tinted and stain deeply with aniline blue. Produced in large numbers, they are at first arranged vertically in a layer of two or three overlapping rows. As plants age the metuloid layer becomes deeper, in one collection forming a continuous zone 300 µ deep, in a second composed of three layers with intertwined hyphae between. In the first collection the context is well developed, occupying the greater part of the fructification and composed of parallel hyphae embedding numerous slender metuloids. In a third thick specimen metuloids occupy most of the context, and are inserted in many overlapping rows, either with context hyphae between, or forming a continuous layer. Most fructifications are resupinate, two being reflexed with narrow pileate margins.

HABITAT: Loosely attached to bark of dead branches.
In a former paper (1953, p. 289) following Cooke I referred a Queensland specimen in Kew herbarium to Peniophora papyrina. From this species Reid has shown that L. papyracea may be separated by the presence in the hymenium and subhymenium of a palisade of cystidioid hyphae, densely encrusted with brown mucilage granules soluble in aqueous solutions of potassium hydroxide. Spores are rare in the specimens examined, a few only attached to basidia being of the dimensions given, although they may not have reached full size. The type of S. percome from Ceylon in Kew herbarium was found to be of this species. S. corruge was based on a stratose specimen.

Hymenophore pileate, annual, coriaceous. Pilei effused-reflexed, sometimes imbricate or scutellate, often resupinate, on lateral branches extending to 20 cm, 0.5-1 cm radius, on vertical branches narrowly effused-reflexed, or conchate, 1-3 x 0.5-1 cm; pileus surface white or cream, radially sulcate and sometimes zoned with one or two light brown bands, finely tomentose; margin inturned, acute, lobed, concolorous; hymenial surface cream, pallid flesh-pink, or orange, shining, finely porose-reticulate with pores 1-4 per mm; often with large, plane, even areas or shallowly punctate, fertile to the edge, when old sometimes creviced. Context white or cream, 0.2-0.5 mm thick, of somewhat loosely intertwined hyphae; generative hyphae to 6 it diameter, walls 0.5-2 µm thick, hyaline, without clamp connections, sometimes crystal encrusted.

HABITAT: Bark or decorticated wood of dead branches.
Merulius corium maybe recognised by the effused-reflexed pilei with white finely tomentose surface, flesh-pink glistening hymenial surface, elliptical spores, and absence of clamp connections. Resupinate forms are common and not infrequently the surface is almost even or delicately punctate, when the species might be mistaken for a Stereum. In a previous paper (1950) I recognised a second species, M. confluens Schw., but now doubt if both can be maintained on any constant morphological feature. Examination of the types in Kew herbarium has shown that Polyporus eriophorus Berk. & Br., ex "Q., Brisbane, F. M. Bailey, No. 419" and Merulius pelliculosus Cke. ex "Vic., Mrs Martin, No. 762" are also synonyms. Specimens of M. aurantius Lloyd from Tasmania, sent by the late L. Rodway to J. B. Cleland also proved to be of this species.

DISTRIBUTION: New Zealand.
HABITAT: Bark of dead fallen branches.
Plants are resupinate and may be recognised by the orange colour of the surface of fresh specimens turning vinaceous when dried, small allantoid spores and thin-walled delicate context hyphae without clamp connections. An orange pigment layer lies beneath the readily separable hymenium, colour being derived from orange mucilage granules encrusting hyphae of the subhymenium. Gloeocystidia arise in folds of the hymenium, and are also embedded among hyphae of the subhymenium and upper part of the context, being larger in the latter region. They are readily overlooked unless sections are stained with aniline blue.

Context dingy white, to 300 µm thick, basal layer narrow, of parallel hyphae which may attain a diameter of 8 µm, irregularly crystal encrusted, intermediate layer of naked intertwined hyphae; generative hyphae 3-5 (8) µm diameter, walls 0.1 µm thick, hyaline, with clamp connections. Hymenial layer to 25 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 14-20 x 4.5-5 µm, bearing 2-4 spores; sterigmata erect, to 4 µm long. Paraphyses subclavate, 12-16 x 4-4.5 µm. Spores elliptic-oblong with rounded ends, 4-4.5 x 2.5-3 µm, a few subglobose when 4 x 3.5 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, New Zealand.

HABITAT: Effused on decorticated fallen branches.
Specimens agree with collections examined in Kew herbarium, save in surface colour and slightly larger diameter of some hyphae of the basal layer. Features by which the species may be identified are the shallow, broken, irregular folds of the pelliculose hymenial layer, small elliptic-oblong spores with rounded ends and hyaline walls, and stout encrusted hyphae of the basal layer, contrasting with the narrower naked hyphae of the intermediate layer. Hymenial reticulations are not arranged in any pattern, but appear as irregular folds simulating shallow pores, raised portions resembling stars or angles, sometimes connected with shallow folds not exceeding 0.4 mm tall. Surface colour varies appreciably. Fresh specimens are pallid cream; when dried, patches develop which are reddish-brown, pallid olive, or fuscous.

HABITAT: Effused on decorticated fallen branches.
Absence of gloeocystidia and clamp connections, presence of paraphysate hyphae, the small basidia, small allantoid spores, and reddish-brown or vinaceous surface of the hymenium separate the species from others present in the region. Many collections resemble resupinate forms of Polyporus merulinus Berk. in surface colour, and in size and shape of spores. They may be separated by certain microfeatures, for P. merulinus is dimitic with clamp connections in the generative hyphae. Although in North America confined to conifers, the species has been found both on conifers and frondose hosts in New Zealand, and occurs mainly on Eucalyptus species in Australia.

Pellicularia filamentosa (Pat.) D.P. Rogers 1943
PAPILIONACEAE. Vinca major: Wellington, Upper Hutt, 20 m. SOLANACEAE. Solanum tuberosum: Auckland, Mt. Albert, 100 m.
Hymenophore annual, effused, readily lifting, spreading over stems of living plants, arachnoid-mucedinioid, forming irregular linear areas to 15 cm long, 2-10 mm wide; hymenial surface white, drying cream or greyish, irregularly slightly tufted; margin thinning out, concolorous, arachnoid. Context white, of a few repent hyphae 8-10 µm diameter, commonly 7-8 µm, walls 0.5 µm thick, without clamp connections; fertile hyphae erect, cymose, ends of branchlets bearing clusters of basidia and paraphyses. Basidia subclavate, some cylindrical, 12-18 x 8-10 µm, bearing 3-4 spores on sterigmata which may attain a length of 15 µm. Paraphyses subclavate, 6-10 x 6-8 µm. Spores elliptical or oblong, some obovate, apiculate, 7-11 x 5-6.5 µm, walls smooth, hyaline, 0.5 µm thick.
DISTRIBUTION: Probably cosmopolitan.
HABITAT: Effused on stems and leaves of living plants.
Recognised by the elliptical spores borne on sterigmata which, at first stout and short, elongate shortly before spores are formed to reach a length of 15 µm. Not infrequently one sterigma is suppressed, basidia then bearing three spores. Although the Pellicularia stage is comparatively rare, the hyphal stage of the species is a well known parasite of many plants. On potato tubers the fungus forms black sclerotia, this stage being long known under the name of Rhizoctonia solani. In a previous paper (Cunningham 1953, c, p. 328) Corticium praticola was listed as a synonym. Flentje has shown that this species, to which he gave the name Pellicularia praticola (Kotila) Flentje (1956, p. 353) may be separated by cultural characters and several minor morphological features.

Pellicularia flavescens (Bonord.) D.P. Rogers
FAGACEAE. Nothofagus fusca: Auckland, Lake Waikaremoana, 600m.
Hymenophore annual, adherent, mucedinioid-membranous, effused forming linear areas to 11 x 3 cm; hymenial surface cream, even or as often somewhat tufted, at length irregularly creviced; margin thinning out, arachnoid, white, adherent. Context white, of several repent hyphae 7-8 (10) µm diameter, branched at a wide angle, walls 0.5 µm thick, without clamp connections; fertile hyphae erect, bearing clusters of basidia and paraphyses. Basidia clavate, 20-26 x 10-14 µm, bearing 2-4 spores on stout sterigmata to 14 µm long. Paraphyses clavate or obpyriform, 10-15 x 5-7 µm. Spores ovate, oval, elliptical with lateral apiculi, sometimes limoniform with one or two apiculi, 11-13 x 7-8 µm, walls smooth, hyaline, 0.5 µm thick.
DISTRIBUTION: Europe, North America, New Zealand.
Habitat: Effused on bark of dead branches.
According to Rogers (1943) spores germinate by repetition. The species may be identified by absence of clamp connections, basidia bearing two or four spores on long stout sterigmata, and apiculate or biapiculate, irregularly oval, ovate, or elliptical spores. The following species resembles P. flavescens closely, differing in the smaller spores, subclavate paraphyses, and in being a plant parasite.

HABITAT: Effused on bark or decorticated decaying wood.
Collections agree with specimens of 'Corticium subcoronatum' examined in Kew herbarium, differing in the slightly smaller more subclavate basidia. The species may be separated from others possessing clamp connections by the small, fusiform or naviculate spores. Branchlets are arranged irregularly, some in coralloid groups, others in cymes. Although basidia collapse early, spores long remain attached by the sterigmata. Oil globules are abundant in the repent hyphae and main branches of the fertile hyphae.

Peniophora affinis Burt 1926 [1925]
UNKNOWN HOST. New South Wales, Mosman.
Hymenophore annual, ceraceous, adherent, effused forming linear areas to 15 x 2 cm, with numerous orbicular outlying islands; hymenial surface at first argillaceous, becoming reddish-buff or chestnut, velutinate, at length deeply but scantily laterally creviced; margin thinning out, white, fibrillose, adherent. Context isabelline, 120-150 µm thick, basal layer well developed, of compact mainly parallel hyphae, intermediate layer of erect hyphae closely compacted and cemented, embedding masses of crystals; generative hyphae to 6 µm diameter in basal hyphae, 3-4 µm in those of the intermediate layer, walls 0-2 µm thick, hyaline, encrusted with both crystals and mucilage granules, without clamp connections. Metuloids scattered or in small groups of 3-5, some projecting to 35 µm, usually subulate with slightly inflated bases and long-acuminate apices, or less often fusiform, 40-75 x 6-9 µm, most finely crystal encrusted where exposed, some naked. Hymenial layer to 25 µm deep, a dense palisade of basidia, paraphyses, and metuloids, encrusted with mucilage granules. Basidia subclavate, 16-24 x 5-6.5 µm, bearing 4 spores; sterigmata slender, erect, to 5 µm long. Paraphyses subclavate, 14-18 x 4-5 µm.

DISTRIBUTION: North America, Europe, Great Britain, West Indies, Australia.
HABITAT: Effused on bark of dead branches.
Specimens match a collection of P. laevis, ex "Sweden, Bygget" in Kew herbarium, so named by H. Bourdot. The species may be identified by the thin-walled subulate projecting metuloids, often in groups of three or five, elliptical or elliptic-obovate spores and absence of clamp connections. Burt described the species under the names P. laevis (Fr.) Burt and P. affinis Burt. Rogers & Jackson (1943, p. 318) have shown the first is invalid, consequently this species, present in Europe as well as North America, should be labelled P. affinis.

Peniophora aspera (Pers.) Sacc. 1916
CONIFERAE. Dacrydium cupressinum: Wellington, Carters Reserve, Carterton, 50 m. Pinus radiata: Wellington, Waverley, 120 m. CORIARIACEAE. Coriaria arborea: Auckland, Waiomu Valley, Thames, 75 m.

New South Wales, Sydney.
Hymenophore annual, membranous, adherent, effused forming irregular areas 5-25 x 5-10 cm; hymenial surface white, then cream, finally alutaceous, granular-arachnoid, or even, finely velutinate, not creviced; margin thinning out, arachnoid, white, adherent. Context white, 200-300 µm thick, basal layer narrow, of parallel hyphae, intermediate layer of densely arranged erect branched hyphae; generative hyphae 4.5-6 µm diameter, walls 0.25 µm thick, hyaline, naked, with clamp connections. Metuloids arising from the intermediate layer, often from its base, projecting to 70 µm, cylindrical or slightly tapering, 60-192 x 6-10 µm, transversely septate, some septa with clamp connections, walls partly encrusted with coarse or fine crystals. Hymenial layer to 35 µm deep, a close palisade of basidia, paraphyses, and metuloids. Basidia cylindric-flexuous, some inflated at the base, 24-32 x 5-6 µm, bearing 4 spores; sterigmata erect, stout, to 6 x 2 µm. Paraphyses clavate, some with an apical bead or digitate process, 12-16 x 5-6 µm. Spores narrowly elliptical with rounded apices, apiculate, usually obliquely so, 7-10 x 3-5 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, Australia, New Zealand.
HABITAT: Effused on bark or decorticated wood of dead branches and trunks.
P. aspera may be recognised by the large, transversely septate, encrusted metuloids, long elliptical spores and arrangement of context hyphae. Metuloids arise from the intermediate tissues, some projecting to 70 µm, whereas others do not extend beyond the surface of the hymenium. The hymenial surface may be even, velutinate, somewhat porose-reticulate, or granular. It was this last condition which led Miller to place the species under Odontia, with which genus it has several features in common; but as most collections examined are even, both from this region and in Kew herbarium, the species is best treated as a Peniophora, and the ancillary organs, although septate, regarded as metuloids. Basidia are frequently cylindrical, and flexuous, with slightly inflated bases. Although commonly known in Europe as Peniophora setigera, in North America as Corticium berkeleyi, Rogers & Jackson (1943, p. 282) held that the most tenable name for the species is P. aspera. They gave a long synonyme list, from which some of the more common synonyms have been taken. Neither spores nor metuloids of Australasian collections attain to the dimensions given by Bourdot & Galzin (1928, p. 309), namely spores 8-11-16 x 3-4-6 µm; metuloids 75-250 x 7-15 µm, but agree with several European collections examined in Kew herbarium.

South Australia, National Park; Mt. Lofty. Podocarpus hallii Wellington, National Park, 1,100 m. LAURACEAE. Beilschmiedia tawa: Auckland, Lake Rotoehu, 400 m. UNKNOWN HOST. South Australia, National Park.
Hymenophore annual, membranous, adherent, effused forming irregularly linear areas 5-15 x 2-3.5 cm; hymenial surface cream, drying sulphur yellow or naples-yellow, at first floccose, becoming even, at length irregularly areolately creviced; margin thinning out, fibrillose, white or cream, loosely attached. Context cream, 150-100 µm thick, basal layer of a few repent hyphae, intermediate layer of intertwined hyphae dense below, loosely arranged beneath the subhymenium; generative hyphae 3.5-4.5 µm diameter, walls 0.25 µm thick, hyaline or tinted, encrusted with fine deciduous crystals, with clamp connections. Metuloids arising from the subhymenium, cylindrical, aculeate or slightly fusiform, projecting to 55 µm, with rounded slightly tapered apices, 50-80 x 4-6 µm, 2-4 transversely septate, with clamp connections at septa, walls encrusted, many becoming naked. Hymenial layer to 60 µm deep, a dense palisade of basidia, paraphyses, and metuloids. Basidia subclavate, 12-18 x 4-4.5 µm, bearing 4 spores; sterigmata erect, slender, to 5 µm long. Paraphyses subclavate, 10-15 x 3.5-4 µm. Spores elliptical, apiculate, 4-1.5 x 2-2.5 µm, walls smooth, hyaline or tinted, 0.1 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, West Indies, Australia, New Zealand.
HABITAT: Effused on bark or decayed wood, humus, or soil.
Characters of the species are the bright yellow colour, loose context composed of intertwined hyphae branching at a wide angle and encrusted with delicate deciduous crystals, corymbose arrangement of basidia and paraphyses, slender, aculeate, transversely septate metuloids with walls encrusted with delicate deciduous crystals, and small spores with walls hyaline or tinted yellow in a spore print. Usually metuloids have been described as smooth, probably because when sections are placed in potassium hydroxide solutions crystals disappear; but crystals are present on most, as may be seen when sections are mounted in lactic acid solutions. Following Karsten, Burt (1917, p. 263) discussed the species under Coniophora; but as Rogers & Jackson (1943, p. 275) have shown, its only resemblance to members of that genus are the tinted spore walls. As metuloids are encrusted, it is evident the species is a Peniophora, related to P. aspera. Most synonyms are given on the authority of Rogers & Jackson (1943, p. 274).

Hymenophore perennial, ceraceous, adherent, at first appearing as numerous- small orbicular or elliptical scattered colonies which may remain discrete or coalesce to form linear areas to 20 x 1-3 cm; hymenial surface some shade of grey, often tinged violet, heliotrope, pinkish, or when old, bay or umber, even or when in small groups often tuberculate, finally deeply laterally creviced; margin either thinning out or abrupt with concolorous or darker border, byssoid, adherent. Context dark brown and glistening in section, 60-240 µm thick, of one or several zones each composed of a scanty basal layer of parallel cemented hyphae with walls coloured brown, and an. intermediate layer of erect compact hyphae and embedded metuloids; generative hyphae to 5 µm diameter, walls 1-1.5 µm thick, chestnut, naked, with clamp connections. Metuloids scattered through intermediate and hymenial layers, some projecting slightly, at first fusiform and naked, becoming conical with prominent coloured pedicels, 24-32 x 10-16 µm, walls coarsely encrusted, metuloids in the base oval or pyriform, 18-24 µm broad. Hymenial layer to 40 µm deep, a dense palisade of basidia, paraphyses, and metuloids. Basidia subclavate, 20-28 x 5-6 µm, bearing 4 spores; sterigmata slightly arcuate, to 4 µm long. Paraphyses subclavate, 16-22 x 4-5 µm. Spores suballantoid, some allantoid, 7-8.5 x 3-3.5 µm walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Cosmopolitan.
HABITAT:Effused on bark or decorticated wood of dead branches.
Metuloids develop from the base of each intermediate layer, and pedicels, being of different lengths, carry them to different positions in the context. They tend to disappear from lower zones of the context, pedicels remaining in position and then resembling gloeocystidia, as do immature metuloids in the current layer. Collections vary appreciably in shape and size of metuloids, thickness and degree of stratification of the context, and in thickness of the basal layer. Normally thin and scanty, in occasional specimens the basal layer may be appreciably thickened, as in a collection from Blechnum filiforme, which agrees with typical forms in other features. According to Eriksson (1950, p. 33) collections labelled Thelephora cinerea in Persoon's herbarium are of the related P. lycii; and the type of P. cinerea is not now in the herbarium of Fries at Uppsala.

Context hyphae afford a ready means of identifying the species. They are stout, thin walled, and so heavily encrusted with masses of mucilage granules as to appear brown in sections, although walls are hyaline. Granules are soluble in potassium hydroxide solutions, turning them a characteristic vinaceous colour, and in alcohol, which is coloured orange. Other basidiomycetes producing similar mucilage are Odontia archeri, Grandinia australis, and Polyporus rutilans.

Context white, drying isabelline, 200-500 µm thick, basal layer well developed, of mainly parallel compacted hyphae with walls tinted in a few next the substratum, intermediate layer of mainly erect hyphae densely arranged; generative hyphae 4-7 µm diameter, walls 0.25-1 µm thick, hyaline, with rare clamp connections, sometimes wanting. Metuloids arising in the hymenial layer when some project to 35 µm and scattered among hyphae of the intermediate layer and subhymenium, conical, subfusiform, or cylindrical with acuminate apices, 55-84 x 8-16 µm, encrusted wholly or upon apices only, crystals deciduous, walls to 5 µm thick in submerged metuloids. Hymenial layer to 40 µm deep, a dense palisade of basidia, paraphyses, and metuloids. Basidia clavate, 14-22 x 4.5-6 µm, bearing 4 spores; sterigmata erect, slender, to 6 µm long. Paraphyses subclavate, 12-18 x 4-5 µm. Spores elliptical or obovate, some with oblique apiculi, 5-6.5 x 2.5-3 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, New Zealand.
HABITAT: Effused on bark or decorticated wood of dead branches and trunks.
But one collection has as yet been found in the region, and agrees with European specimens examined, differing only in the smaller size of fructifications, these being roughly orbicular and 2.5 cm across. The species may be recognised by the almost cartilaginous context (when dry) and large, thick-walled metuloids embedded in the context. The latter are completely encrusted, whereas those of the hymenial region are thin-walled, and only partly encrusted, or some may be naked, resembling then some of those of P. cremea. Hyphae are of large diameter, but naked, and exhibit occasional clamp connections, about one per cent of septa bearing them. Although recorded for New Zealand by Colenso (1895, p. 614), no specimens are in Kew herbarium from the region.

Only the type collection has yet been found. Metuloids are encrusted on their upper third with either granules of yellow or orange mucilage, or calcium crystals, sometimes both being present on the same metuloid. Similar crystals and granules are present on portions of the context hyphae. Because of the bright colour of granules, metuloids are readily seen in sections. According to E. M. Wakefield granules are soluble in alkalies, producing a bright yellow solution.

HABITAT: Effused on bark or decorticated wood of dead fallen or attached twigs and small branches.
Peniophora lycii is abundant in New Zealand and shows a partiality for dead twigs attached to living plants. Its main specific feature is the presence in the hymenium of branched paraphysate hyphae which sometimes develop additionally in the context. They may be conspicuous and appear like miniature antlers, or delicate with one or two branches only, and are encrusted (Fig. 62) with fine refractive crystals which may extend to contiguous basidia, paraphyses, and projecting metuloids. Spores are larger than those of P. cinerea and P. nuda, consequently as they are always present, these two features enable the species to be identified readily.

TYPE LOCALITY: Waitakere Ranges, Auckland, New Zealand.
DISTRIBUTION: New Zealand.
HABITAT: Effused on dead leaf midribs.
P. nikau and P. longispora show a close resemblance in structure of the context and especially in shape of metuloids. The latter are aculeate, taper from bases to apices, project for about half their length, are relatively thin-walled, and bear small tuberculate, scattered crystals often resembling plates or scales. P. nikau is separated by its spores of different shape and size, and more delicate metuloids. In a former paper it was described under the name of P. sororia; as this is occupied (Bourdot & Galzin, 1912, p. 386) the species has been renamed after the Maori name of the host.

Peniophora nuda, P. lycii, P. cinerea, and the extralimital P. violaceo-livida form a small group of related species. In all the context is waxy and composed of brown hyphae firmly cemented by their walls, spores are suballantoid or allantoid, and the hymenial surface is coloured some shade of grey. Probably species are perennial, although specimens with one or two zones of context are most frequently collected. Thanks to the excellent work of Eriksson (1950) it is possible to identify all four readily. P. nuda is separated by the presence of pyriform or clavate gloeocystidia. According to Eriksson (1950, p. 43) the type is no longer in the herbarium of Fries at Uppsala.

Specific features are the abundant, broadly elliptical, small spores, narrow metuloids often capitate and bearing fine crystals, loosely arranged encrusted context hyphae and white or cream, fragile hymenophore. In collections from this region metuloids are distinctly encrusted, whereas in European specimens examined in Kew herbarium, some bore only a few crystals, and many were naked. Because of this the species has sometimes been treated as a Corticium, and metuloids described as 'cystidioles'.

Hymenophore annual, membranous, fragile, at first adherent, when old somewhat loosely attached, effused forming irregular areas to 15 x 7 cm, with a few outlying islands; hymenial surface mustardyellow, pruinose, often finely papillate, at length scantily creviced; margin thinning out, fibrillose, concolorous, adherent. Context yellow, 150-250 µm thick, basal layer well developed, of intertwined mainly erect hyphae, more freely branched in the subhymenium; generative hyphae to 5 µm diameter, walls 0-2 µm thick, hyaline, branched at a wide angle, without clamp connections, some naked, most encrusted with coarse hyaline crystals or yellow mucilage granules; the latter coating most of the hyphae of the subhymenium, forming a deeply coloured zone. Metuloids arising in the subhymenium, some projecting to 50 µm, cylindrical with rounded apices, a few slightly irregular, 1-3 transversely septate, 40-75 x 5-7 µm, walls bearing a few mucilage granules or crystals below apices, some naked. Hymenial layer to 35 µm deep, a close palisade of basidia, paraphyses, and metuloids. Basidia subclavate or cylindrical; 16-22 x 4.5-5 µm; bearing 1-2-4 spores; sterigmata slightly arcuate, to 6 µm long. Paraphyses subclavate, 12-16 x 4-4.5 µm. Spores elliptical or suballantoid, apiculate, 4-5-6 x 2.5-3 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: North America, New Zealand.
HABITAT: Effused on bark or decorticated dead wood.
Hyphae of the subhymenium and upper part of the intermediate layer are densely encrusted with yellow mucilage granules like those of P. filamentosa. Metuloids are commonly cylindrical with rounded apices, occasionally strangulated, or geniculated, one to three transversely septate with thin hyaline walls bearing scattered granules or crystals near the hymenial surface, or naked. Our collection agrees with North American specimens save that spores are slightly smaller.

Scytinostroma odoratum (Fr.) Donk 1956
UNKNOWN HOST. New South Wales, near Sydney.
Hymenophore annual or biennial, ceraceous, adherent, effused forming irregular areas to 12 x 5 cm; hymenial surface cream or pallid ochre, pruinose, not creviced; margin thinning out, white, fibrillose, adherent. Context white, 200-400 µm thick, basal layer a narrow zone of parallel hyphae closely compacted, intermediate layer mainly of skeletal hyphae embedding gloeocystidia; skeletal hyphae freely branched, 2-3 µm diameter, walls 0.5 µm thick, aseptate, staining deeply; generative hyphae 3-4 µm diameter, walls 0.1 µm thick, not staining, without clamp connections. Gloeocystidia scattered, obclavate, cylindrical, or subfusiform, some projecting slightly, arising in the context, 45-80 x 7-10 µm, contents at first of yellow oil globules, becoming vitreous. Hymenial layer to 65 µm deep, an obscure palisade of basidia, paraphyses, and gloeocystidia. Basidia irregular in shape, cylindric-flexuous or subclavate, soon collapsing, 30-48 x 5-6 µm, bearing 4 spores; sterigmata slightly erect, slender, to 5 µm long. Paraphyses scattered, subclavate or cylindrical, 24-36 x 4-5 µm. Spores obovate, oval, or pip-shaped, often flattened on one side, with lateral apiculi, 7-9.5 x 5-7 µm, walls smooth, hyaline, 0.1 µm thick, nonamyloid.
DISTRIBUTION: Europe, North America, Australia.
HABITAT: Effused on bark or decorticated dead wood.
Skeletal hyphae form the bulk of the intermediate layer and are thick-walled, aseptate, and stain deeply. Among them lie the thin-walled, freely septate generative hyphae, which are without clamp connections and do not stain with aniline blue. Gloeocystidia arise from generative hyphae among the skeletal hyphae of the intermediate layer. At first conspicuous because of the yellow contents, in old specimens contents become glassy, when gloeocystidia are often difficult to detect. Occasional branches of skeletal hyphae pass through the hymenium to appear above the surface, as simple or finely branched paraphysate hyphae. Basidia, at first somewhat irregular, soon become elongated, flexuous, and project slightly. Spores vary in size and shape, most being somewhat pip-shaped with lateral apiculi. The collection listed agrees with Swedish specimens in the herbarium. The species differs from the related S. galactinum in the larger spores and absence of clamp connections; and from S. ochroleucum by the smaller spores and narrower basidia.

Hymenophore perennial, stratose, membranous, adherent, effused forming irregular areas to 30 x 7 cm, with a few orbicular, scattered, outlying islands; hymenial surface cream, alutaceous, or pallid buff, resembling chamois leather, not creviced; margin at first thinning out, soon becoming cliff-like, or receding, adherent, concolorous or pallid tan when old. Context varying in thickness with age, 0.1-1.5 mm thick, tan or isabelline, composed of numerous (5-20) layers differentiated by bands of generative hyphae, parallel branches of skeletal hyphae, scattered crystals, or thinning of the tissues; basal layer narrow, of parallel hyphae closely compacted, intermediate layer of erect branched skeletal hyphae embedding crystals which may be compacted into vertical lenses; skeletal hyphae with erect stems traversing the context, producing lateral branches which may be straight or curved, at the surface becoming entwined laterally and covering the hymenium, 3-4.5 µm diameter, walls 0.5-2 µm thick, aseptate, naked; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, naked, with clamp connections. Gloeocystidia absent. Hymenial layer composed of scattered groups of basidia and paraphyses. Basidia cylindrical, 20-32 x 5-6 µm, bearing 2-4 spores; sterigmata erect, slender, to 5 µm long. Paraphyses scanty, subclavate, 12-22 x 3-4 µm. Spores globose or subglobose, some apiculate, 4.5-6 µm diameter, walls hyaline, smooth, 0.2 µm thick, nonamyloid.
DISTRIBUTION: North and South America, Europe, East and West Indies, Australia, New Zealand.
HABITAT: Bark and decorticated wood of dead branches.
Skeletal hyphae, which form the bulk of the context, are thick-walled, aseptate, and stain deeply. They arise as upright stems with lateral branches projecting at intervals, in whorls, binding the context into a compact tissue. Basidia are delicate, cylindrical, embedded among curved branches of the skeletal. hyphae, arise in small groups, and collapse as soon as spores mature. Old specimens are stratose and composed of several layers visible under a lens. In both macrostructure and microstructure the species resembles Scytinostroma duriusculum. Both are perennial, with similar branched skeletal hyphae, basidia, and spores, S. duriusculum differing in possessing gloeocystidia (Talbot, 1951, p. 51).

Through the courtesy of L. Harmsen, Denmark, who kindly forwarded specimens, I have been able to recognise S. himantioides among collections present in this region. The species differs from S. lacrymans, to which it was referred as a variety by W. B. Cooke (1957a, p, 207) by structure, thin-walled hyphae of the context, and narrower spores.

Serpula lacrymans (Wulfen) J. Schröt. 1888 [1889]
CONIFERAE. Agathis australis: Auckland City. Dacrydium cupressinum: Canterbury, Christchurch. Pinus radiata: Wellington, city. Podocarpus spicatus: Wellington, city; Wallaceville. UNKNOWN HOSTS. Auckland, Mt. Albert; Mt. Eden; Sandringham.
Hymenophore pileate or more usually resupinate, when pileate pilei effused-reflexed, when resupinate indefinite in size and shape, membranous, loosely attached; hymenial surface ferruginous, irregular, sometimes plane, rugose, nodulose, or coarsely reticulate when pores are angular, 1-4 mm diameter, reticulations entire, to 1 mm tall, edges somewhat acute; margin indefinite, with abundant coarse rhizomorphs. Context at first white, drying grey or various shades of brown, 0.5-5 mm thick, basal layer duplex, of hyphae to 8 µm diameter, walls chestnut and so thickened that lumena are capillary, sparsely branched, septate with one or two clamp connections at septa, often with brief lateral, coralloid branches arising from them, intermediate layer of hyaline hyphae of two types (1) 7-8 µm diameter, walls 1-2.5 µm thick, or so thickened that lumena are capillary (2) 3-4 µm diameter, walls 0.5 µm thick, both freely branched, septate, with clamp connections. Hymenial layer to 100 µm deep, a close palisade of basidia and paraphyses, separated from the context by a dense intertwined layer of hyaline hyphae. Basidia clavate, 20-28 x 4-6 µm, bearing 4 spores; sterigmata slightly arcuate, slender, to 6 µm long. Paraphyses subclavate, 16-24 x 4-5 µm. Spores elliptical or slightly obovate, sometimes flattened on one side, 8-12.5 x 4.5-6 µm walls smooth, chestnut or ferruginous, 0.25 µm thick.
DISTRIBUTION: Common in temperate and subtropical regions.
HABITAT: Effused on building timbers in confined areas, causing a destructive brown cubical rot, and from timber spreading to adjacent masonry, soil, etc.
Although only a few collections are stored in the herbarium, S. lacrymans is common throughout New Zealand, and causes a decay of building timber brought in contact with moisture, or inadequately ventilated. It is equally destructive to boxes and woodwork in glasshouses, cool frames, and the like. Specimens vary appreciably in appearance and size, and configuration of the hymenial surface, according to the conditions under which they have developed. Some may appear as thick, effused-reflexed or dimidiate pilei, most are resupinate often appearing as large sheets with rhizomorphs which may project for metres beyond margins of fructifications. The hymenial surface may be conspicuously porose-reticulate, gyrose when resembling certain species of Phlebia, or plane.

Serpula pinastri (Fr.) W.B. Cooke 1957
DECAYED WOOD. Auckland, Whakarewarewa, 400 m. SOIL IN GLASSHOUSE BOXES. Auckland, Mt. Albert, 50 m.
Hymenophore resupinate, annual, membranous, loosely attached, fragile when dry, forming irregular orbicular or linear areas to 4 x 3 cm; hymenial surface yellow or yellow-olive, ferruginous when dry, at first porose-reticulate with pores 0.5-1.5 mm diameter, becoming gyrose or irpiciform, with folds 1-3 mm tall; margin thinning out, 2-3 mm wide, white or cream, crenate, edges fibrillose. Context white, 100-600 µm thick, intermediate layer of mainly erect hyphae closely compacted and embedding numerous gloeocystidia in the upper parts of folds, basal layer of mainly parallel hyphae with few or many hyaline or coloured cordons 25-40 µm diameter; generative hyphae 4-5 µm diameter, walls 0.1 µm thick, hyaline or yellow in the base, with ring-like clamp connections. Gloeocystidia confined to the upper parts of the folds, freely developed, not projecting, cylindrical or subclavate, 20-55 x 5-8 µm, walls 0.1 µm thick, contents staining deeply. Hymenial layer to 35 µm deep, a close palisade of basidia and paraphyses. Basidia clavate, 22-28 x 8-9 µm, bearing 2-4 spores; sterigmata erect, slender, to 4 µm long. Paraphyses cylindrical, 16-22 x 3-5 µm. Spores oval or broadly elliptical, with rounded ends, apiculate, 5-6.5 x 3.5-4.5 µm, walls smooth, tinted golden yellow, 0.5 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, New Zealand.
HABITAT: Effused on rotten wood, wood debris, and soil.
Specific features are the frequently irpiciform or gyrose folds of the hymenial surface, broad sterile margins of lighter colour, loosely attached fructifications with the abhymenial surface fibrillose with coloured or hyaline cordons, and golden yellow, oval or broadly elliptical spores which possess rather thick walls staining deeply with aniline blue. Cordons are conspicuous and composed of closely compacted hyphae (15-30) with hyaline or yellow walls. Gloeocystidia are usually abundant and confined to folds of the hymenial layer. Of various shapes and sizes, they appear to be inflated portions of context hyphae, some clearly defined. They were noted also in European specimens examined in Kew herbarium. Hyphae of the four collections listed are of lighter colour than those of European specimens examined; but in old plants, or parts thereof, especially of cordons, walls are golden yellow. Spore walls also range in colour from hyaline to golden yellow. The habitat is also noteworthy; for two collections were taken from the surface of soil in boxes in glasshouses, two from rotten wood lying beneath houses.

Hymenophore pileate, annual, coriaceous, commonly solitary, often gregarious, rarely caespitose. Pilei usually flabelliform or spatulate, sometimes infundibuliform with one side split to the base, 2-4 cm tall, 8-20 mm wide; pileus surface bay, bright chestnut or sometimes ferruginous, even or radiately sulcate, concolorous or as often banded with darker zones either radiately or transversely; sometimes silky and with scattered surface hairs, more abundant in the darker zones and towards bases of pilei; margin thinning out, crenate, sometimes deeply incised; hymenial surface even, when fertile white and appearing farinose, creviced when old, radiately sulcate. Stems arising from bay, prominent mycelial discs, to 8 x 1 mm, finely velutinate, bay or umber. Context isabelline or wood colour, 0.2-0.6 mm thick, composed of radiately arranged parallel hyphae; with a coloured cortex; skeletal hyphae 4-4.5 µm diameter, lumena capillary; generative hyphae 3-3.5 µm diameter, walls 0.2 µm thick, with clamp connections. Gloeocystidia arising from the base of the subhymenium, traversing the hymenium but not projecting, some lying among the context hyphae, cylindrical or ventricose-cylindrical, sometimes flexuous and moniliform, 40-96 x 8-12 µm. Hymenial layer to 160 µm deep, a dense palisade of basidia, paraphyses, gloeocystidia, and paraphysate hyphae. Basidia subclavate, 16-25 x 5-6 µm, bearing 1-2-4 spores; sterigmata slender, erect, to 4 µm long. Paraphyses subcylindrical, 8-20 x 4-5 µm. Paraphysate hyphae scanty or abundant, cylindrical, 3 µm diameter, projecting to 10 µm, sometimes submoniliform. Spores oval or broadly elliptical, a few subglobose, 4-4.5 x 3-3.5 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: East Indies, South Africa, New Guinea, Australia, New Zealand.
HABITAT: Usually solitary on decorticated decayed wood lying upon the forest floor.
Specific characters are the scattered and scanty often moniliform abhymenial hairs, woody context, deep hymenial layer containing abundant long and narrow gloeocystidia, small oval or broadly elliptical spores, spatulate or flabelliform pilei attached to broad mycelial discs, and habitat. In several features the species varies appreciably. Depth of the hymenial layer, and consequent length of gloeocystidia, is affected by position, becoming deeper, and gloeocystidia larger, from apices to bases of pilei. Abhymenial hairs may be scanty or relatively plentiful, solitary or arranged in small tufts. Often submoniliform, they are usually arranged in bands which traverse pilei laterally. Pilei are usually flabelliform or spatulate; occasionally they may be infundibuliform or campanulate, with one side split. Stems are attached to broad mycelial discs; sometimes two or three arising from the same disc. Surfaces may be concolorous or show lateral bands of darker brown. Spores are usually oval or broadly elliptical, without apiculi, and measure 4-4.5 x 3-3.5 µm. One of the collections was named by Cooke as S.obliquum Berk. & Mont.; several others were misnamed by Lloyd as S. sowerbeii, S. elegans, and S. surinamense.

UNKNOWN HOSTS. New South Wales, Pine Creek. Fiji, Suva.
Hymenophore annual, coriaceous, pileate, sessile. Pilei commonly flabelliform or conchate, attached by a small umbo, occasionally applanate with lateral edges inrolled, solitary or crowded, 1.5-4 cm radius, 2-5 cm wide; pileus surface densely tomentose, or even, lanate when young, straw colour or dingy ochre, concentrically ridged and furrowed, sometimes concentrically zoned with concolorous hairs, becoming denuded in concentric areas exposing the chestnut cortex; hymenial surface at first chestnut, drying cinereous, reddish where bruised, concentrically furrowed, or even, at length deeply radiately creviced. Context isabelline, 0.3-0.8 mm thick, a dense layer of radiately arranged parallel hyphae, bordered by a coloured cortex of cemented parallel hyphae bearing the abhymenial hairs; skeletal hyphae to 6 µm diameter, walls 1-1.5 µm thick; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, without clamp connections. Conducting hyphae modified from skeletal hyphae, penetrating the hymenial layer but not projecting, inflated to 8 µm, walls 1-1.5 µm thick, contents orange. Hymenial layer to 85 µm deep, a dense palisade of basidia, paraphyses, and conducting hyphae. Basidia subclavate, 16-24 x 4-4.5 µm, bearing 4 spores; sterigmata slender, erect, to 5 µm long. Paraphyses cylindrical or subclavate, 12-20 x 3.5-4 µm. Spores elliptical, apiculate, 4-6 x 3-3.5 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: North and South America, West Indies, Madagascar, South Africa, Fiji, Australia.
HABITAT: Solitary or crowded on bark of dead branches.
Specimens agree with authentic material from Madagascar examined in Kew herbarium. The species is close to S. fasciatum in general appearance, especially surface features, differing in colour of the hymenial surface, thicker context, broader spores, and especially, presence of conducting hyphae. The last are modified ends of skeletal hyphae containing orange contents which stain deeply. They simulate cystidioid hyphae, differing in contents and greater abundance. When fresh the hymenium if cut bleeds as in S. sanguinolentum. From the latter the species differs in possessing a dimitic hyphal system, whereas in most 'bleeders' the hyphal system is monomitic, conducting hyphae being modified from generative hyphae. Occasional acanthophyses were noted in the Madagascar collection, but are absent from specimens collected in this region.

Paraphyses subclavate, 12-18 x 3.5-4 µm. Spores elliptical or elliptic-obovate, 3.5-5 x 2.5-3 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Europe, Great Britain, North America, South Africa, Malaya, Australia.
HABITAT: Bark or decorticated wood of decayed branches.
Stereum bicolor is represented in this region by two collections (labelled type) of S. pannosum Cke: & Mass. ex "Victoria, Korumburra, Mrs Martin, Nos. 1067,1071" which match European specimens examined in Kew herbarium. The species may be identified by the coffee-coloured pileus surface and white or cream hymenial surface, loosely intertwined hyphae of the context with brown walls and conspicuous clamp connections, monomitic hyphal system, prominent gloeocystidia, and absence of a cortex. In the possession of a monomitic hyphal system and gloeocystidia it resembles S. aotearoa. Because of the arrangement of context hyphae the species is not a typical Stereum, and was accordingly made the type of Laxitextum by Lentz (1955, p. 18).

HABITAT: Solitary or sometimes caespitose on bark of dead branches.
From S. lamellatum the species is separated mainly by the absence of crystal-encrusted thick-walled 'cystidia' in the hymenial layer. Spores of collections listed are smaller than measurements given by Reid (1955, p. 635) for S. caperatum. He stated they were subcylindrical, 8-11 x 3-4 µm. Reid placed S. caperatum and S. lamellatum under Cymatoderma, a name which must replace Cladoderris Pers. ex Berk. for those who recognise the genus. Although Persoon (1826, p. 176) suggested the name for a specimen collected by Gaudischaud on Sarawak, he actually described it under Thelephora dendritica Pers. With a formal description Berkeley (1842, p. 152) validated Cladoderris, overlooking that earlier Junghuhn (1840, p. 290) had erected Cymatoderma with as type C. elegans Jungh. Typical specimens of Cymatoderma elegans agree closely with Stereum caperatum and C. lamellatum in microfeatures, differing mainly in shape and configuration of the hymenial surface, which is thrown into sharp, freely branched ribs with several (or none) papillae developing from, them. I am of the opinion that such features alone are insufficient upon which to base a genus and this belief is strengthened by similarity of microstructure. As the presence of a stem is scarcely of generic value, and as the hymenium of S. caperatum and S. lamellatum is either even like an ordinary stipitate Stereum; or exhibits channels corresponding with surface ridges, it is evident that this feature alone is insufficient and too variable upon which to maintain them under Cymatoderma. Gloeocystidia are commonly of the. type found in S. affine and most other stipitate species; so cannot in themselves be regarded as of generic value. Some arise more deeply in the context, are flexuous-cylindrical and penetrate to the surface of the hymenial layer; being then larger than those of the usual type. A few become inflated and thus foreshadow the larger 'cystidia' of S. lamellatum. From the cortex some generative hyphae grow out as abhymenial hairs, then becoming thick-walled and simulating skeletal hyphae, differing in that they bear occasional clamp connections. A similar condition was noted by Reid in S. lamellatum. Basidia are slow to.produce spores, which appear first towards the base of the fructification.

Pilei infundibuliform, or split on one side to the stem apex, sometimes flabelliform, often rosetted, with stems discrete but apices concrescent, 15-35 mm tall, 12-30 mm wide; pileus surface glabrous, bay or tobacco-brown, concolorous or with darker lateral zones, radiately plicate; hymenial surface grey when fertile, when sterile ochre or pallid brown, irregularly fluted, creviced longitudinally when old; margin thinning out, concolorous, crenate, often deeply lobed or incised, somewhat translucent. Stems 5-10 mm long, 1-4 mm wide, sometimes fused but usually single although several may arise from a common mycelial base, finely velutinate, concolorous. Context wood colour, 0.3-0.5 mm thick, of radiately arranged parallel compact hyphae; skeletal hyphae 3.5-4 µm diameter, lumena capillary; generative hyphae 3.5-4 µm diameter, walls 0.2 µm thick, with clamp connections.

HABITAT: Growing from buried wood on the forest floor.
Since the type no longer exists, many workers have been confused as to the specific features of S. elegans . Judged from numerous specimens examined in Kew herbarium, these call for plants with rosetted pilei, several usually arising from discrete stems and becoming apically concrescent. Pilei are thin and brittle, often appearing translucent, and spores are broadly elliptical, apiculate, 5-6 x 3-3.5 µm. The habitat also is noteworthy, plants arising from decayed wood buried in humus. As pilei vary from solitary and flabelliform to campanulate concrescent forms, pileus features are not sufficient to enable species to be identified accurately. Identifications of early workers, based on these, cannot be regarded as trustworthy; consequently the distribution given is that of authentic specimens examined in Kew herbarium, or received from collectors. The species is close to S. affine, differing in pileus shape, habitat, and slightly larger apiculate spores. Flabelliform, specimens of both, if sterile, are difficult to separate. Welden (1954, p. 437) listed as a synonym S. flabellatum Pat.; a second is S. floriforme Bres., ex "Aireys Inlet, Victoria, Miss Berthon"; and S. sowerbeii Berk. is merely a small form without any constant differentiating features.

Following examination of collections in Kew herbarium and the abundant specimens available in Australia and New Zealand I am satisfied that S. fasciatum, S. lobatum, and S. ostrea are merely forms of one variable species. Types of S. perlatum ex Philippine Islands, S. concolor from Tasmania, and a Kew collection labelled S. leichkardtianum are also based on this one species. In the region are found specimens similar to those upon which Burt (1920b, pp. 155, 163) attempted to separate S. fasciatum from S. lobatum. According to latitude, altitude, and age they exhibit varying growth conditions, from flabelliform through effused-reflexed to resupinate, and degree of hairiness of the surface, ranging from tomentose to almost naked. Typical plants are large, lobed, and zoned with naked and tomentose concentric areas. Plants collected while young, or from mountain areas, may be smaller, more hirsute, often effused-reflexed and frequently resupinate. It is therefore not possible to maintain the two species on macrofeatures, and in microfeatures they are identical. In a previous paper (Cunningham, 1956b, p. 218) the species was described under the name of S. lobatum. It appears that the most likely epithet for the species is S. fasciatum, since this was the first applied valid name, so far as is at present known, and the type is extant.

Lloyd (1920c, p. 1008) referred the collection from Queensland to S. annosum Berk. & Br. (syn. S. durum Burt, S. burtiasmus Lloyd, S. rhabarbarinum (Berk. & Br.) Wakef.). With this tropical species it agrees in the presence of acanthophyses and stratose context. It differs in the type of acanthophyses and in being resupinate. Specimens of S. annosum from Ceylon and Uganda examined in Kew herbarium are, pileate with effused-reflexed pilei, and acanthophyses are of different size and shape, and bear digitate processes throughout their length. Australian collections differ from typical specimens of S. frustulatum in that the resupinate fructifications are only tardily laterally creviced (Queensland specimen) or areolately creviced (New South Wales specimen), whereas European collections usually break into polygonal frustules which continue to grow after separation, so that each frustule ultimately becomes pulvinate like those of Corticium kauri. Acanthophyses are the same in both Australian and European collections, as are basidia and spores. Acanthophyses are similar to those present in S. illudens and S. subpileatum Berk. & Curt. (syn. S. insigne Bres., S. sepium Burt). They become cemented into a palisade in the hymenial layer, and persist to form the coloured zones so conspicuous in sections when examined under a lens. When fertile, the hymenial layer consists mainly of basidia and paraphyses, when sterile this layer is composed almost entirely of acanthophyses. Colenso (1886, p. 304) recorded the species from New Zealand, the record being based on two collections so named in Kew herbarium, ex "N.Z. Colenso, b. 252, b. 297". Labelled on the sheet by Lars Romell as S. rufum, they are collections of Acanthophysium berggreni and bear such a striking superficial resemblance to some collections of S. frustulatum that Lloyd (1925, p. 1336) also recorded the species from the Dominion, as his photograph (f. 3087) shows. The specimen from Nowra, New South Wales, was by E. M. Wakefield (1915, p. 370) recorded under the name of Stereum rhabarbarinum. Examination showed it to possess microfeatures of S. frustulatum, differing in that, although deeply creviced, the plant is continuous and not broken into frustules as in most European collections. Because of the arrangement of context hyphae the species is an anomalous Stereum and but for its dimitic hyphal system would be better placed under Acanthophysium.

Hymenophore annual or perennial, coriaceous, sessile. Pilei effused-reflexed, flabelliform, umbonate, or resupinate, often laterally connate with a broad resupinate base and reflexed margins, 1-3 cm radius, 1-15 cm wide; pileus surface chestnut or vandyke-brown with a greyish base, coarsely strigose-hirsute, concentrically sulcate and zoned with various shades of brown hairs, sometimes complicate with lateral margins infolded, frequently radiately sulcate; margins acute, plane, concolorous or darker, entire; hymenial surface showing irregular zoning and sulcate markings of the surface, even, plum, violaceous, or lead colour, or tinted heliotrope or violet, finally deeply creviced often around the centres of attachment. Context ferruginous or fuscous, sometimes stratose, 0.3-1 mm thick, commonly 0.3-0.5 mm, of radiately arranged parallel hyphae, with a coloured cortex beneath abhymenial hairs and a colour zone beneath the hymenial layer; skeletal hyphae 4-6 µm diameter, walls 1 µm thick, tinted yellow-brown, darker when old; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, hyaline, without clamp connections.

Collections agree with the type in Kew herbarium, ex "Swan River, Western Australia, No. 158". The species may be identified by the pallid brown context with rich chestnut cortex, coarsely strigose hirsute surface and presence of acanthophyses and cystidioid hyphae in the hymenial layer. Collections vary, exhibiting three main growth forms: (1) large effused-reflexed or flabelliform plants often laterally connate, common on fallen trunks and branches; (2) small flabelliform or umbonate plants common on power poles, or upright stems of shrubs; and (3) resupinate forms common on worked timber such as handrails, boxing, and flooring, in which the fungus produces a destructive decay. In the first, acanthophyses are delicate, bearing spines which rarely exceed half a dozen in number and 0.5 µm in length; in the second, prominent, bearing numerous spines which may reach a length of 4 µm and exceed a dozen in number, in the third they may be delicate or well developed. Usually the surface is strigose-hirsute, chestnut, concentrically sulcate and zoned with several shades of brown hairs, the basal portion being less hirsute and often grey. Hairs may partly disappear, exposing zones of dark cortex, or be shed completely, when the surface appears polished and black. Colour of the hymenial surface also varies appreciably: when fresh it may be light pinkish-buff, plum, or tinted violet or heliotrope; old specimens usually weather to lead or ashy grey, and become deeply creviced, often more prominently around the point of attachment. Some plants are stratose, bearing from two to five layers with receding margins. Resupinate plants, common on worked timber, in appearance resemble resupinate specimens of S. fasciatum but differ in possessing acanthophyses.

Hymenophore annual, coriaceous, centrally stipitate. Pilei commonly infundibuliform, sometimes with one side partly suppressed, or 2-3 flabelliform pilei may merge to form rosetted clusters, 6-12 x 4-10 cm; pileus surface cream or wood colour, coarsely and radiately ridged, acute margins sometimes toothed, with between ridges a dense tomentum to 3 mm thick and lighter in colour; margins acute, plane or slightly inrolled, crenate and torn; hymenial surface decurrent, cream or buff, with radiate rounded ridges, which may be branched towards apices, bearing a few scattered papillae. Stems 3-5 cm tall, 5-15 mm diameter, occasionally shorter and often merged at the base into several, usually clothed with dense tomentum with a darker margin where the hymenium ends, attached by a prominent mycelial disc. Context white, to 1 mm thick, becoming progressively thinner from base to apex, of radiately arranged parallel hyphae, bordered by a cemented cortex of hyaline intertwined hyphae bearing abhymenial hairs; skeletal hyphae 3-4.5 µmdiameter, lumena almost capillary; generative hyphae 3-4 µm diameter, walls 0.2 µm thick, with clamp connections.

HABITAT: Solitary or caespitose on bark of dead branches.
From S. caperatum the species may be separated by one feature alone, the presence of cystidial in the-hymenial layer. These organs differ markedly from metuloids of Peniophora for they are without pedicels, of different shape, and crystals which encrust parts are deciduous and disappear in aqueous-solutions of potassium hydroxide. Their appearance and the presence of many transitional stages between them and gloeocystidia indicate that they are old gloeocystidia in which walls have become thickened and partly covered with crystals. All stages between them and typical gloeocystidia may be seen in sections, and they are present also in rudimentary form in S. caperatum; although without crystals in that species. Study of a large series of specimens will no doubt show that the feature is not constant and that plants are merely forms of one variable species.
Pilei vary appreciably in shape, size, length of stems, and in surface features. Commonly infundibuliform, specimens examined may consist of two or several fused either at the base or margins; several pilei may become flabelliform then fuse at margins to form rosettes; or pilei may split on one side and only partly develop. One stem may support two pilei 1 or conversely several stems may develop but fuse in rosetted plants. Stems may be long and cylindrical, or short and tapering, be round, flattened, or often fluted, and are usually clothed, with coarse tomentum, although sometimes naked. The surface may bear few or many radiate lamellae with acuminate margins, their number, size, and colour varying in almost every -specimen examined: Between them develops a dense tomentum which maybe 3 mm deep, and vary in colour from cream to buff; or be suppressed, when the naked pileus appears reddish-brown.

Context isabelline with darker base, 0.5-1.5 mm thick, composed of erect hyphae compacted into a pseudoparenchyma, embedding numerous vesicles and, in lower layers, masses of crystals; skeletal hyphae 3-3.5 µm diameter, walls 1 µm thick; generative hyphae 2-2.5 µm diameter, walls 0.2 µm thick, with clamp connections.

HABITAT: Effused on bark of dead trunks.
Commonly resupinate, the species would normally be regarded as a Corticium, since it possesses the microstructure of stratose species of that genus, save that the hyphal system is dimitic. In North America pileate forms have been collected, pilei being narrow and scarcely more than upturned margins with a hard, horny, naked black cortex. From S. purpureum, which also bears vesicles, it may be separated by the thick fructifications with ochre or buff hymenial surface, stratose context with numerous vesicles scattered throughout, and erect hyphae of the layers of the context. Vesicles are usually pyriform or obovate; beneath the hymenial layer arise a few which, fusiform or ventricose in shape, may attain a length of 65 µm, penetrate the hymenial layer and simulate gloeocystidia. In the base of the context, hyphae become discoloured and somewhat cemented; they produce the black line bordering the hymenium of resupinate specimens and form the cortex of pileate plants. The species was made the type of Cystostereum Pouzar (1959, p. 18).

Pilei infundibuliform or campanulate, sometimes split along one side when becoming flabelliform, 10-20 mm tall, 10-20 mm wide; pileus surface tan or chestnut, radiately sulcate, concolorous or with darker bands which are somewhat tomentose, with hairs more densely arranged above stems; hymenial surface when fertile grey, when sterile some shade of brown, scantily vertically creviced when old; margin thinning out, concolorous or lighter, dentate or often deeply incised. Stems to 10 x 2 mm, equal, bay, velutinate with prominent hairs, arising from well developed mycelial discs. Context white or isabelline, 0.25-0.4 mm thick, of radiately arranged parallel hyphae, with a coloured cortex bearing abhymenial hairs which may be brief or elongate, with rounded or moniliform apices and walls to 1 µm thick; skeletal hyphae to 4 µm diameter, lumena almost capillary; generative hyphae 3.5-4 µm diameter, walls 0.2 µm thick, with clamp connections.

Collections listed agree with authentic specimens examined in Kew herbarium. In microfeatures the species resembles S. affine and S. elegans, differing in that gloeocystidia are of greater diameter and possess thicker walls (0.5-1 µm). Spores are of the same size and shape as those of S. elegans, but larger than those of S. surinamense. Pileus hairs are more strongly developed than in S. affine and S. elegans, although of similar shape and diameter. They occur in zones on the pileus surface and irregularly above the stem. The latter is strongly velutinate as in S. affine and arises from a mycelial disc. S. ravenelii Berk. & Curt. is similar, differing mainly in the glabrous pileus, which may be a variable condition. About 30 species of small stipitate Stereums have been described. Most examined in Kew herbarium appear to be forms of half a dozen basic species, having been erected on slight differences in shape, size, or colour of pilei, colour of the hymenium, or upon the nature of the substratum. They may be divided into two groups, upon whether hyphal systems are monomitic (S. pusiolum)or dimitic (S. afffine, S. elegans, S. pergamenum, S. surinamense, S. thozetii),and within these a few may be delimited by spore size. Separation of the others can be made only upon variable macrofeatures, consequently most will have to be suppressed when a large series of specimens is studied critically.

Hymenophore annual, membranous, pileate, sessile. Pilei effused-reflexed or flabelliform, solitary or more usually laterally connate and imbricate, sometimes with a broad resupinate base and reflexed margins, occasionally resupinate, 3-10 mm radius, 3-15 mm wide, when connate forming linear areas to 20 cm long; pileus surface coarsely tomentose, concentrically sulcate and zoned, usually straw colour or tan, sometimes dingy grey, occasionally with denuded zones; margin thinning out, concolorous, entire, inturned; hymenial surface even, sometimes scantily rugulose, ochre, pallid plum or purple, occasionally creviced when old. Context white, 0.3-0.5 mm thick, a dense layer of radiately arranged parallel hyphae with a loosely intertwined zone beneath the hymenium containing vesicles, and a coloured cortex from which arise the abhymenial hairs; skeletal hyphae 3.5-4 µm diameter, walls 0.5-1 µm thick; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, with clamp connections. Vesicles developing in a zone beneath the hymenial layer, arising from generative hyphae, pyriform, 12-18 µm diameter, carried on stout pedicels. Hymenial layer to 50 µm deep, a dense palisade of basidia, paraphyses, and sometimes paraphysate hyphae. Basidia subclavate, 16-24 x 5-6 µm, bearing 4 spores; sterigmata slender, erect, to 6 µm long. Paraphyses subelavate, 12-18 x 4-5 µm. Cystidioid hyphae absent. Paraphysate hyphae cylindrical, to 5 µm diameter, projecting to 35 µm. Spores elliptical, or with one side slightly flattened, obliquely apiculate, 5.5-8 x 2.5-3.5 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Cosmopolitan.
HABITAT: Crowded and often imbricate upon living or dead trunks and branches.
Readily recognised by the zone of pyriform vesicles beneath the hymenial layer, coarsely tomentose small pilei, often connate and imbricate, dimitic hyphal system with clamp connections in the generative hyphae, and small elliptical, obliquely apiculate spores. Vesicles are readily seen in growing specimens, but in old material collapse and lose their contents or disappear, then leaving cavities in the context. Occasional vesicles are flexuous-cylindrical, traverse the hymenial layer, and simulate gloeocystidia. A coloured cortex is present beneath abhymenial hairs, as in S. hirsutum, but cystidioid hyphae are wanting. Paraphysate hyphae are present in some collections, absent from others, so are without specific significance. The hyphal system is dimitic. Skeletal hyphae, although of about the same diameter as generative, differ in that walls are thicker, septa scanty, and clamp connections wanting. Commonly some shade of purple, the hymenium often exhibits other colours, such as ochre, pallid plum, or grey. In some plants the context, and especially the hymenial layer, appears zoned, the condition probably representing periods of seasonal growth. S. purpureum induces a silver leaf disease of many cultivated fruits, in New Zealand being common on apples, apricots, cherries, gooseberries, peaches, pears, plums, and raspberries. Although usually found in introduced hosts, it is not confined to these since in the herbarium are collections from endemic New Zealand plants, two on branches of Nothofagus cliffortioides, a third on stems of Pittosporum tenuifolium. In most collections spores are 5.5-6 x 2.5-3 µm but in several specimens may reach a length of 8 µm. Large-spored forms are not associated with any other noteworthy feature. The species was made the type of Chondrostereum by Pouzar (1959, p. 17).

Stems arising from a mycelial bulb, 1-5 mm long, 0.5-1 mm thick, naked, concolorous with the hymenium. Context 0.4-0.8 mm thick, wood colour or light brown, composed of radiately arranged parallel hyphae; generative hyphae 2.5-3 µm diameter, walls 0.5 µm thick, naked, with clamp connections.

Hymenial layer to 70 µm deep, a dense palisade of basidia, paraphyses, and gloeocystidia. Basidia subclavate, 26-45 x 7-9 µm, bearing 2-4 spores; sterigmata slender, erect, to 8 µm long. Paraphyses subclavate, 16-30 x 5-6 µm. Spores subglobose or pip-shaped, apiculate, 4.5-6 x 4-4.5 µm, walls smooth, hyaline, 0.5 µm thick.
DISTRIBUTION: West Indies, Central America, New Zealand.
HABITAT: Growing on soil, usually gregarious.
Collections agree in microfeatures with type specimens examined in Kew herbarium. These consist of eight small plants, ex "Cuba, C. Wright, No. 510" and are smaller than typical collections from New Zealand. Plants vary in size, shape, and colour. They are constant as to habitat, contrasting colours of surface and hymenium, monomitic hyphal system with clamp connections in generative hyphae, small subglobose spores, and presence of gloeocystidia with coloured contents. Welden (1954, p. 431) thought the species so closely resembled S. radicans (Berk.) Burt that it might be regarded as a variety. Judging from Lloyd's descriptions and figures, it is probable that S. cuneoforme Lloyd, S. grandi Lloyd, and S. multifidum Lloyd are synonyms.

Pilei are mostly effused-reflexed with broad resupinate bases, and sometimes arise from borer holes in the substratum. Conspicuous conducting hyphae are present in the context and hymenial layer. They exude a reddish fluid when the surface of living specimens is cut or bruised. Spores are narrowly cylindrical with rounded ends, or as often allantoid. In the collection from Dacrydium cupressinum they are somewhat larger (to 10 x 4 µm), than those from other hosts listed, but agree with authentic European specimens in other particulars. The species was made the type of Haematostereum Pouzar (1959, p. 13).

Recognised by the monomitic hyphal system, pigmented conducting hyphae, hyaline acanthophyses, small size, silky surface, thin context, and presence of a coloured cortex. Collections examined are the type of Stereum radiato-fissum ex "Queensland, Thozet, No. 277" which Bresadola on the type sheet and later (1916, p. 232) referred to S. spectabile Kl.; "N.S.W., Mosman, J. B. Cleland, May 1917" referred by Lloyd to S. radiato-fissum; "N.S.W., Sydney, J. B. Cleland, March 1915" the type of S. obscurum Lloyd, which Lloyd held to be a variety of S. spadiceum, "N.S.W., Lisarow, J. B. Cleland, June 1916" which Lloyd misnamed S. bellum Kze., and a collection ex "N.S.W., Beecroft, Mrs M. Blackwell, March 1955". The species is a 'bleeder' with monomitic hyphal system and well developed conducting hyphae containing granular, contents which discolour in dried specimens and stain deeply in. sections. According to J. B. Cleland, the surface also turns red when bruised, a feature of most species with conducting hyphae. Acanthophyses resemble those of S. illudens.

Hymenophore annual, coriaceous-ceraceous, pileate, sessile. Pilei commonly effused-reflexed with broad resupinate bases, applanate, dimidiate, frequently laterally connate and often imbricated, sometimes resupinate, 5-30 mm radius, 5-25 mm broad, or when connate expanded laterally to 15 cm; pileus surface coarsely tomentose, tomentum at first chestnut, soon concentrically sulcate and zoned with bands of different colours, in old specimens bases grey with margins chestnut, finally becoming grey or dingy brown; margin thinning out, entire, inturned, concolorous; hymenial surface at first chestnut and even, with zones corresponding with those of the surface, becoming black and polished, remaining so or ultimately becoming tuberculate. Context glistening, chestnut or fuscous, 0.2-0.5 mm thick, composed of mainly radiately arranged parallel hyphae sometimes embedded in mucilage; cortex densely compacted, chestnut, abhymenial hairs chestnut, walls 1 µm thick; generative hyphae 3.5-4 µm diameter, walls 0.2-0.5 µm thick, with conspicuous clamp connections. Paraphysate hyphae arising, from the subhymenium and projecting to 20 µm, branched, hyaline, freely septate, collapsing. Hymemal layer to 80 µm deep, a dense palisade of basidia and paraphyses.

DISTRIBUTION: North and South America, South Africa, India, Malaya, Fiji, Australia, Tasmania, New Zealand.
HABITAT: Bark of dead trunks and branches.
Specific features are the densely tomentose, concentrically zoned, chestnut pilei, polished black hymenium, chestnut context, monomitic hyphal system with clamp connections in the generative hyphae, and branched paraphysate hyphae of the hymenial layer. At first the hymenium is even and, if plants are collected when young, it remains smooth although changing in colour from chestnut to black. As plants become fertile the hymenium may become finely tuberculate, or remain even, both conditions being present in collections listed. Context tissues appear to be gelatinised because of the brown and glistening appearance of sections, but in reality are composed of somewhat loosely arranged mainly parallel hyphae sometimes embedded in gelatinous matter. A coloured cortex is present, as in S. hirsutum and related species. Bresadola (1916, p. 231) referred the species to Auricularia rugosissima (Lev.) Bres. They resemble one another in surface features but differ profoundly in microstructure. He later (1925, p. 480) referred it to Auricularia strigoso-zonata (Schw.) Bres. This treatment probably arose through Bresadola mistaking for basidia, paraphysate hyphae of the hymenial layer, which to the casual observer may resemble germinating basidia of Auricularia. Basidia are holobasidia, however, and bear four sterigmata carrying elliptical spores, as is shown in Fig. 120. This is not easy to ascertain unless adequate sections are prepared, for at an early stage paraphysate hyphae collapse and form an amorphous gelatinous layer upon the hymenial surface. Through this, developing basidia are forced, sometimes becoming distorted in transit, and produce spores above the gelatinous surface. Paraphysate hyphae may be seen readily in immature portions of developing plants, and sometimes fragments of branches persist on the surface of mature specimens. The species exhibits all the features of a Stereum, save that in occasional specimens the hymenial layer becomes tuberculate, or tuberculate-striate; consequently it is referred to this genus, and not to Phlebia, with which it has little resemblance. The species was made the type of Phaeophlebia by W. B. Cooke (1956, p. 401).

Fructifications are usually solitary and infundibuliform or campanulate, pileus surfaces are glabrous, concentrically zoned with bands of light and dark brown, and hymenial surfaces are even. The narrow, tinted cortex is without abhymenial hairs. Stems are velutinate and attached to the substratum by broad mycelial discs. Gloeocystidia are ventricose-flexuous and conspicuous. Spores are the smallest of those seen in stipitate species, and readily overlooked unless sections are examined with an oil immersion objective.

MYRTACEAE. Leptospermum ericoides: Auckland, Huia, 20 m, type collection, P.D.D. herbarium, No. 4392.
Subiculum annual, membranous, white, loosely attached, to 160 µ. thick, effused forming small and sharply defined orbicular or linear areas 1-15 mm long, of closely intertwined hyphae. Pilei aggregated in groups of few (4-6) opening many (30-80) in scattered areas, seated in loculi, depressed globose, 250-600 µ diameter, opening tardily by a narrow naked pore; exterior covered with felted white tomentum, becoming naked, even, almost black; hymenial surface even, white or cream, concave; loculi filled with loosely intertwined freely branched hyphae bordered by a more compact intertwined zone. Context fuscous, to 70 µ thick, composed of parallel densely arranged hyphae pseudoparenchymatous in the base; generative hyphae 2-4 µ diameter, walls 0.25 µ thick, hyaline, fuscous near the periphery. Hymenial layer to 40 µ deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 24-32 x 6-7 µ, bearing 4 spores; sterigmata slightly arcuate, to 6 µ long. Paraphyses subclavate, 18-26 x 5-6 µ. Spores oblong with rounded ends, apiculate, 7-9 x 5-6.5 µ, walls smooth, hyaline, 0.2 µ thick.
TYPE LOCALITY: Huia, Auckland.
DISTRIBUTION: New Zealand.
HABITAT: Crowded on bark of dead stems.
Pilei are crowded in groups in the felted subiculum. Each is embedded in a distinct locule, defined by a compact wall and filled with loosely intertwined hyphae. As pilei mature, the apical portion becomes partly denuded of tomentum, and ruptures by a narrow pore. Attached to the walls are densely arranged abhymenial hairs which are freely branched, almost dendrophytic, and encrusted with masses of crystals. They are ultimately shed near apices, but elsewhere remain, and serve to retain each pileus within its locule

Hymenophore annual; membranous, centrally stipitate, composed of numerous (15-26) erect branches arising from a simple stem attached to a broad mycelial base, to 4 cm tall, 3 cm across, stems to 10 mm long and 5 mm wide; main branches chocolate; terete, 1-2 mm diameter, some slightly flattened, becoming once, twice, or thrice branched either dichotomously or irregularly, terminating in usually bifid tips grey or ochre in colour; hymenial surface amphigenous below, inferior on upper branches, even, chocolate. Context of numerous cordons of loosely arranged parallel hyphae with intertwined hyphae between; generative hyphae 4.5-5 µm diameter, walls 0.2 µm thick, tinted brown, freely branched at a wide angle, septate, with numerous often proliferating clamp connections. Hymenial layer to 160 µm deep, of 1-3 layers, a close palisade of basidia and paraphyses. Basidia clavate, 30-40 x 7-8 µm, bearing 4 spores; sterigmata erect, slender, to 6 µm long. Paraphyses clavate, 12-22 x 5-6 µm. Spores broadly oblong or oval, 8-10 x 7-8 µm, walls sinuate, finely sparsely verruculose, tinted ferruginous, 0.2 µm thick.
DISTRIBUTION: Australia.
HABITAT: Solitary or gregarious on the ground.
When well developed, plants possess a freely branched pileus attached to a stout short.stem arising from a bulbous mycelial base. Primary branches are stout, and bear secondary branches which in turn may branch once or twice, either dichotomously or irregularly, tips being of lighter colour and broadened slightly. The hymenium is amphigenous on stems and main branches, inferior above, the surface being rich chocolate and even. Basidia develop in corymbose clusters each surrounded by several paraphyses. Cordons are abundant in tissues of the stem, lying parallel with one another and separated by loosely intertwined hyphae. Some hyphae of which cordons are composed may be lactiferous as they contain deeply staining contents. Variability in size and shape of plants is considerable, almost every specimen examined differing in size, number of branches and type of branching. Although three species with this form of fructification have been described from Australia, examination of the types of Thelephora congesta and 'Stereum' simulans ex "Brisbane, F. M. Bailey" have shown them to be based on plants of the same species. Thelephora archeri Berk. has been shown by Reid (1956, p. 536) to be an heterobasidiomycete which he referred to Pseudotremellodon pusio (Berk.) Reid. Even the generic position has been in doubt. Both Bresadola and Lloyd referred Thelephora congesta and Stereum simulans to Lachnocladium , and Lloyd (1919, p. 15) listed Thelephora archeri and Lachnocladium congestum under Dendrocladium.

Thelephora griseozonata Cooke 1891
ON HUMUS. Canterbury, Balmoral State Forest, 350 m.
Hymenophore commonly rosetted, formed from several erect flabelliform pilei fused at margins, attached by a central base; margins entire, or torn, but not lobed; exterior surfaces of pilei scabrid, exhibiting several concentric, ferruginous, grey, chestnut, or umber colour zones sometimes demarked by raised strigose tufts on the periphery of zones; hymenial surface umber, finely tuberculate. Microfeatures as in T. terrestris.
DISTRIBUTION: North America, New Zealand.
HABITAT: Encrusting humus under pines.
Specimens were collected in a plantation of Pinus ponderosa and match the type in Kew herbarium, ex "Aitken, South Carolina, H. W. Ravenel". The species is merely a well marked form of T. terrestris, identical in microfeatures, differing in shape and surface features of pilei and different habitat. The most marked character is that dorsal surfaces of the pilei are concentrically zoned with bands of grey and brown, a second that margins of pilei are fused to form erect infundibuliform rosettes.

Western Australia, Mundaring.
Hymenophore annual, membranous, humicolous, sometimes encrusting living or dead plants, forming pilei of diverse shapes and sizes. Pilei applanate, flabelliform, sometimes merged to form erect rosettes, 1-10 cm tall and broad; surface ferruginous or umber, covered with strigose tufts which are concolorous or darker and sometimes imbricated hymenial surface ferruginous or umber, often vinaceous, radiately striate, even or finely tuberculate; margins crenate, sometimes freely lobed or toothed, bluntly rounded or torn, concolorous. Context 1-5 mm thick, ferruginous, basal layer forming the greater part of the fructification, of loose parallel hyphae associated with parallel strands of closely compacted hyphae; generative hyphae 4-6 µm diameter, walls 0.2-0.5 µm thick, pallid yellow brown, naked, freely branched often at a wide angle, septate, with clamp connections. Hymenial layer to 90 µm deep, a close palisade of basidia and paraphyses. Basidia subclavate, 32-45 x 8-10 µm, bearing 2-4 spores; sterigmata arcuate, to 8 µm long. Paraphyses subclavate, 22-35 x 6-8 µm. Spores subglobose or irregularly oval, 8-10 µm diameter, or 8-11 x 7-9 µm, walls sinuate, finely sparsely verruculose, pallid ferruginous, 0.5 µm thick.
DISTRIBUTION: Cosmopolitan.
HABITAT: Encrusting humus under pines.
Although only a few collections are listed, the species may be found in any plantation of Pinus radiata. It has evidently been introduced with seeds or plants, since it is not found in any other habitat. There is no evidence showing that the fungus forms a mycorrhiza with pines; nor is the species a plant parasite, though known occasionally to kill pine seedlings by growing around stems and smothering them. In macrofeatures the species varies so considerably that it is difficult to draw an accurate description of the fructifications. Commonly plants grow over pine needles, humus, and soil under pines, the mycelium encrusting the surface over an area of many square metres. From the mycelium pilei arise. Usually flabelliform, they may merge to form erect rosettes, or sometimes campanulate pilei.

T. crustosa was erected on a form with small flabelliform fructifications. Pilei may remain entire; or more commonly become torn into few or several lobes, T. laciniata being a name applied to specimens displaying the latter condition. Colour may range from ferruginous to dark umber, or umber with a vinaceous tinge; the pileus surface may be clothed with coarse strigose tufts, slender down-pressed bundles of hairs, or remain almost smooth. The hymenial surface may be even, or, as often tuberculate or radially striate. Most conditions may be found in one ample collection, showing that these are merely variable growth conditions. Spores are subglobose or more often oval, walls bearing 3-5 rounded lobes, giving them a sinuate appearance. Spore walls are covered with short, scanty, broad-based verruculae, which may be hyaline or tinted brown like the spore wall.

DISTRIBUTION: Europe, New Zealand.
HABITAT: Effused on bark of dead branches.
Separated from T. fusca by the lighter colour, adherent colonies, hyaline hyphae of the intermediate layer and smaller spores. Collections agree with a specimen from Europe examined in Kew, herbarium, named by Bourdot T. fusca subsp. castanea. I have followed Donk in considering the plant as a species, rather than a subspecies of T. fusca, under which it was placed by Bourdot & Galzin.

Tomentella epiphylla (Schwein.) G. Cunn. 1939
UNKNOWN HOST: New South Wales, Garie Beach.
Hymenophore annual, membranous, loosely attached, effused forming small irregular areas 2-4 x 1-2 cm; hymenial surface umber or sepia, granulose, not creviced; margin thinning out, concolorous, loosely attached, fibrillose, sometimes with scattered rhizomorphs. Context sepia, to 400 µm thick, a loose weft of intertwined hyphae becoming erect beneath the hymenium, with in the base numerous cordons to 50 µm diameter, composed of 20-35 parallel compacted hyphae; generative hyphae 3.5-4 µm diameter in the subhymenium, in the base of the context to 8 µm, walls 0.2 µm, thick, some roughened slightly, ferruginous, tinted beneath the hymenium, freely branched at a wide angle, septate, with clamp connections.

DISTRIBUTION: North America, Great Britain, Europe, Australia.
HABITAT: Bark or decorticated wood of dead branches.
Specimens agree with collections of 'Hypochnus granulosus' examined in Kew herbarium. The species may be recognised by the granulose surface, rather stout basal hyphae, presence of large cordons near the base, strongly sinuate coarsely echinulate spore walls, and dark colour of the context. Basidia and paraphyses are grouped in corymbs, forming a loose palisade and giving to the surface its granulose appearance. Cordons are conspicuous and may be seen with the aid of a hand lens when the upper layer is dissected away. Because of their presence the species was placed by Bourdot & Galzin (1928, p. 507) under the section 'Chordulatae', containing in addition T. rubiginosa (Bres.) Maire (with two subspecies T. gresicola B. & G. and T. hasicola B. & G.), T. coriaria (Peck) Bourd. & Galz., and T. botryoides (Schw.) Bourd. & Galz. Burt at first used the name Hypochnus granulosus for the species; later, following examination of the type of Hydnum epiphyllum, he held (1926b, p. 320) that the correct specific epithet was Hypochnus epiphyllus.

Spores are slightly larger than those of authentic European specimens examined, but in other features collections agree. Specific features are the dark colour of the hymenial surface which is often chocolate and tinted vinaceous, loose attachment of fructifications, absence of cordons, and coarsely aculeate, sinuate spore walls of a colour similar to the context hyphae. Spores bear a prominent apiculus, which may be obscured by the coarse aculeae.

Cystidia cylindricalia, 56-90 x 6-8 µ, apicibus ad 10 µ inflatis, cervice crassis crystalis cincta. Basidia clavata, 12-16 x 5.5-6 µ, 4 sporis. Sporae ellipticae, 4-4.5 x 3-3.5 µ, parietibus levibus, hyalinis. On dead bark of Dacrydium cupressinum, Weheka, Westland, N.Z.
Cystidia are cylindrical, apices inflated, with girdling bands of crystals at bases of inflated areas. Five species with inflated apices to the cystidia have been named, T. accedens (B. & G.) Donk, `Peniophora' juniperina Bourd. & Galz., T. regifica (Jacks. & Deardn.) Donk, T. sceptrifera (Jacks. & Were.) Donk and T. thermometra. T. cincta agrees most closely with T. regifica and T. sceptrifera. It differs from the latter by the shape of the cystidia, and from T. regifica by the smaller cystidia with bands of girdling crystals, and smaller spores.

HABITAT: Effused on trunks of tree ferns.
Hymenophorum membranaceum, adnatum, effusum; superficie straminea, pallide ochracea siccante, velutinata, alte areolato rimosa. Hyphae generatoriae fibulatae, 2-2.5 µ diam. Cystidia subulata, basis radicatis, saepe geniculata, 55-75 x 6-10 µ, lumenibus capillatis, in vaginis hypharum implicatis. Basidia cylindricalia, 12-16 x 5-7 µ, 4 sporis. Sporae allantoides, 6-8 x 2-2.5 µ, parietibus levibus, hyalinis. On dead pendent stipes of Cyathea dealbata, Waitakere Ranges, Auckland, N.Z.
Cystidia stain deeply with aniline blue, but are not amyloid. They are irregular both in size and shape and crowded into irregular rows in the hymenial layer and context. Most are subulate, some bifid near apices, others bear a lateral branch about midway, others again are flexuous or the apical part is geniculated. Roots vary in numbers and shape, some being freely branched so that they appear almost dendriform. When branched portions are detached accidentally in preparing sections they appear like dendriform structures among the context hyphae. The habitat is unusual, the collection being taken from hard black residual bases of dead stipes forming the exterior of a tree fern trunk.

Hymenophore annual, membranous, adherent, effused, forming linear areas to 12 x 3 cm; hymenial surface cream, pruinose, deeply areolately creviced; margin thinning out, arachnoid, white, adherent. Context white, 80-150 µm thick, basal layer of a few repent hyphae, intermediate layer of densely arranged mainly erect hyphae among which, at the base, are few or many thick-walled hyphae; generative hyphae 2.5-4 µmdiameter, walls 0.5 µm thick, naked, with clamp connections. Cystidia arising from the basal layer and projecting to 65 µm, naked, cylindrical, 65-144 x 8-12 µm, lumena capillary, apices thin-walled and rounded. Hymenial layer to 25 µm, deep, a close palisade of basidia, paraphyses, and cystidia. Basidia subclavate, 12-16 x 4-5 µm, bearing 4 spores; sterigmata erect, slender, to 8 µm long. Paraphyses subclavate, 6-10 x 3.5-4 µm. Spores cylindrical or allantoid, with rounded ends, 6-8 x 1.5-2 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: North America, Europe, Great Britain, South Africa, Australia, New Zealand.
HABITAT: Effused on bark or decorticated wood of dead branches.
Cystidia are cylindrical, with walls so thickened, save at apices, that lumena are capillary. Apices remain thin-walled, so that cystidia simulate inverted miniature thermometers. Cystidia arise in the context as deeply staining, thin-walled organs, resembling gloeocystidia. Shortly their walls become thickened from within until lumena are almost obliterated. Spores are similar in shape to those of T. subalutacea, but smaller. The intermediate tissue consists mainly of erect sparsely branched hyphae with, near the base, intertwined convoluted thick-walled hyphae of the same diameter. The latter are extensions of basal roots of the cystidia, may be abundant or scanty, and sometimes occupy one-third of the base of the context. As the name Peniophora glebulosa (Fr. ex Bres.) Sacc. & Syd. cannot be employed for the species, being a nomen confusum, Rogers & Jackson applied to the cystidiate species of the complex, with a validating description, the herbarium name used by Ellis & Everhart.

DISTRIBUTION: Canada, Eastern United States, New Zealand.
HABITAT: Decorticated wood of dead branches.
The New Zealand collection agrees with the excellent type description, differing only in that cystidia are slightly broader and spores slightly larger. T. praeterita most closely resembles T. rimicola in structure of the context, manner in which basidia and cystidia arise, verruculose spores, and presence of capitate paraphysate hyphae. It differs in that spores are larger and of different shape, with more prominent verrucae and thicker walls, and in the stout shorter cystidia and thinner context.

HABITAT: Effused on bark or decorticated wood of dead branches.
When fresh, fructifications are somewhat gelatinous, farinose from projecting cystidia, and tinted greyish-blue; when dry they become firm and horny, often appearing varnished and in sections glistening. T. rimicola offers difficulties in its interpretation. It evidently belongs to Tubulicrinis since cystidia are naked and develop directly from basal hyphae, not upon pedicels. An intermediate tissue is wanting, the hymenium arising from surface hyphae of the basal layer. The latter, at first delicate and composed of a few repent hyphae, becomes extensive as plants develop, in some collections appearing obscurely stratose and embedding collapsed cystidia. Finally hyphae of the basal layer, save near the fertile area, become gelatinised, collapsed, and almost amorphous. Spores are delicately but distinctly verruculose, size and abundance of verrucae varying in different collections. Cystidia are relatively thick-walled at bases, walls becoming progressively thinner towards apices, and in that region soon collapse. Capitate paraphysate hyphae are present in the hymenial layer and may be abundant or scanty in different collections.

Cystidia are expanded slightly from bases to apices, and walls become thickened progressively from apices to bases. In several collections they are arranged in clusters in small spines, so that the species might be sought under Odontia of the Hydnaceae; but in other particulars are identical with even collections listed. Spores are allantoid, some cylindrical, and in shape resemble those of T. gracillima.

Hymenophore a tenuous greyish film barely visible upon the substratum, annual, arachnoid, adherent, to 5 x 2 cm; hymenial surface dingy white, delicately pruinose, arachnoid; margin arachnoid, white, adherent. Context a tenuous layer 10-18 µ, thick, basal layer of a few repent hyphae, soon collapsed, intermediate layer wanting; generative hyphae 2-2.5 µ diameter, walls 0.2 µ thick, naked, with clamp connections. Cystidia arising in the base of the context and projecting for the greater part of their length, cylindrical or slightly attenuated towards the rounded and inflated apices, 45-64 x 4-6 µ, bases forked, lumena capillary, save at apices where expanded and bulbous, walls naked or as often enmeshed in delicate hyphal sheaths. Hymenial layer composed of scattered basidia, paraphyses, and cystidia. Basidia clavate, 6-8 x 4-5 µ, bearing 4 spores; sterigmata arcuate, to 4 µ long. Paraphyses clavate, 4-6 x 3-4 µ. Spores globose, apiculate, 3.5-4 µ diameter, walls smooth, hyaline, 0.2 µ thick.
TYPE LOCALITY: Hicks Bay, Auckland, New Zealand.

HABITAT: Effused on decayed decorticated fallen trunks.
Cystidia project for almost their entire length, and are cylindrical or slightly tapering with inflated apices; walls, save at apices, are so thickened that lumena are capillary, and are destroyed with aqueous solutions of potassium hydroxide. They become enmeshed in hyphal sheaths. Apices are thin-walled and inflated so that cystidia, like those of T. gracillima, resemble miniature inverted thermometers. Basidia are small, clavate, and develop directly, from hyphae of the basal layer. Fructifications appear as delicate white or greyish arachnoid films upon the surface of fallen decayed trunks; visible to the eye when fresh, in the herbarium fructifications can be seen only with the aid of a dissecting microscope.
The species resembles T. accedens (B. & G.) Donk in shape of the cystidia, but differs in the smaller basidia, globose spores and more delicate fructifications.

Cystidia arising in the base of the context and projecting for the greater part of their length, cylindrical or slightly attenuated towards the rounded and inflated apices, 45-64 x 4-6 µm, bases forked, lumena capillary, save at apices where expanded and bulbous, walls naked or as often enmeshed in delicate hyphal sheaths. Hymenial layer composed of scattered basidia, paraphyses, and cystidia. Basidia clavate, 6-8 x 4-5 µm, bearing 4 spores; sterigmata arcuate, to 4 µm long. Paraphyses clavate, 4-6 x 3-4 µm. Spores globose, apiculate, 3.5-4 µm diameter, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: New Zealand.
HABITAT: Effused on decayed decorticated fallen trunks.
Cystidia project for almost their entire length, and are cylindrical or slightly tapering with inflated apices; walls, save at apices, are so thickened that lumena are capillary, and are destroyed with aqueous solutions of potassium hydroxide. They become enmeshed in hyphal sheaths. Apices are thin-walled and inflated so that cystidia, like those of T. gracillima, resemble miniature inverted thermometers. Basidia are small, clavate, and develop directly from hyphae of the basal layer. Fructifications appear as delicate white or greyish arachnoid films upon the surface of fallen decayed trunks; visible to the eye when fresh, in the herbarium fructifications can be seen only with the aid of a dissecting microscope. The species resembles T. accedens (B. & G.) Donk in shape of the cystidia, but differs in the smaller basidia, globose spores and more delicate fructifications.

Tubulicrinis umbraculus (G. Cunn.) G. Cunn. 1963
MYRTACEAE. Leptospermum ericoides: Auckland, Great King Island. WINTERACEAE. Pseudowintera colorata: Otago, Horseshoe Bay, Stewart Island, type collection, P.D.D. herbarium, No. 13660.
Hymenophore annual, membranous, adherent, effused forming irregular colonies, 1-4 x 0.5-2 cm; hymenial surface cream, even although at first often porose, not creviced; margin thinning out, arachnoid, white, adherent. Context white, 30-50 µ thick, basal layer of a few repent hyphae, intermediate layer of scanty mainly erect hyphae; generative hyphae 4-5 µ diameter, walls 0.5 µ thick, naked, often inflated between septa, with clamp connections. Cystidia arising from the basal layer or subhymenium and projecting to 50 µ, cylindrical, 35-70 x 10-12 µ, tapering to apices where each is capped with a crystalline body to 8 µ diameter, resembling a miniature parasol, with radiating ridges terminating in acute spines, walls naked, thickened to 3 µ. Hymenial layer to 20 µ deep, a loose palisade of basidia, paraphyses, and cystidia. Basidia subclavate, 10-14 x 5-6 µ, bearing 4 spores; sterigmata slender, erect, to 5 µ long. Paraphyses subclavate, 8-10 x 3.5-4 µ. Spores elliptical, sometimes flattened on one side, or obovate, apiculate, 5-6 x 3-3.5 µ, walls smooth, hyaline, 0.2 µ thick.
TYPE LOCALITY: Stewart Island, Otago, New Zealand.
DISTRIBUTION: New Zealand.
HABITAT: Effused on bark or decorticated dead branches.
Cystidia project for the greater part of their length, are moderately thick-walled, taper from bases, and bear upon apices caps of fused crystals which resemble miniature parasols. The exterior of each cap is ribbed and ribs terminate in acute down-pointed spines. But one other species with such a feature has been described, T. hamata (Jacks.) Donk, which differs in the larger basidia and differently shaped spores. Walls of cystidia are naked and are destroyed with solutions of potassium hydroxide although the apical `caps remain inaltered.
Tubulicrinis vermicularis (Wakef.) G. Cunn. 1963
FILICALES. Cyathea medullaris: Auckland, Kauri Park, Birkdale, 100 m; Earthquake Flat, Rotorua, 500 m. Cyathea smithii: Taranaki, Mt. Egmont, 900 m.
Hymenophore annual, arachnoid, adherent, effused forming small linear or irregular areas 2-8 x 0.5-1 cm; hymenial surface white, even, finely velutinate, not creviced; margin thinning out, arachnoid, white, adherent. Context white, 15-25 µm thick, basal layer compact, of mainly parallel hyphae often embedding lenses of crystals, intermediate layer wanting; generative hyphae 2-2.5 µm diameter, walls 0.2 µm thick, naked, with clamp connections. Cystidia arising from the surface of the basal layer, projecting for the greater part of their length, subulate, 44-80 x 8-12 µm, apices bluntly acuminate, bases forked, apical regions of some at first encrusted with coarse crystals, becoming smooth when cystidia are enmeshed in hyphal sheaths. Hymenial layer an irregular palisade of scattered basidia, paraphyses, and cystidia. Basidia subclavate, 10-16 x 5-6 µm, bearing 2-4 spores; sterigmata slender, to 4 µm long. Paraphyses subclavate or as often obclavate, 10-12 x 3.5-4 µm. Spores lunate with acuminate ends, 9-11 x 3.5-4 µm, walls smooth, hyaline, 0.2 µm thick; sometimes adhering in fours, or pairs.
DISTRIBUTION: New Zealand.
HABITAT: Effused on dead pendent stipes of tree ferns.
Separated from T. vermifera by the smaller cystidia and basidia, lunate spores, and effused fructifications confined to dead pendent stipes of tree ferns. Some cystidia are at first encrusted apically with coarse deciduous crystals, then simulating metuloids; these soon disappear, to be replaced by hyphal sheaths. Spores are lunate and may adhere in pairs or fours. Lenses of crystals are often embedded in the context, hyphae of which collapse and become gelatinised. Collections match the type of 'Peniophora' vermicularis in Kew herbarium, ex "N.Z., Whakarewarewa, W. N. Cheesman, on a fern petiole."

Hymenophore annual, sometimes biennial, cretaceous, adherent, forming small elliptical or orbicular colonies 5-10 mm long, or linear areas 0.5-5 x 0.5-1.5 cm; hymenial surface white or pallid cream, velutinate, not creviced; margin abrupt, white, ceraceous, adherent. Context white, 50-300 µm thick, basal layer scanty, of parallel hyphae embedding masses of crystals, intermediate layer wanting; generative hyphae 2-2.5µm diameter, walls 0.2 µm thick, naked, with clamp connections. Cystidia arising from the base of the context, projecting for the greater part of their length, thick-walled, naked, or enmeshed in delicate hyphal sheaths, subulate, 80-135 x 10-16 µm, apices acuminate, bases inflated, forked. Hymenial layer to 20 µm deep, a scanty interrupted palisade of basidia, paraphyses, paraphysate hyphae, and cystidia. Basidia subclavate, 25-35 x 6-7 µm, bearing 1-2-4 spores; sterigmata stout, arcuate, often spread laterally, to 10 µm long. Paraphyses subclavate, scanty, 15-20 x 4-5 µm. Paraphysate hyphae cylindrical or branched, 2-2.5 µm diameter, projecting to 15 µm. Spores flexuous-naviculate, bases rounded and apiculate, apices long-acuminate and geniculated, 18-26 x 5.5-6 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Western Europe, North America, New Zealand.
HABITAT: Maculiform on bark of dead or living stems.
Both T. vermifera and T. vermicularis possess subulate cystidia projecting for the greater part of their length, unusual spores, and are without an intermediate layer. Cystidia are thick-walled, readily etched with solutions of potassium hydroxide, and possess strongly radicate bases. At maturity they are enmeshed in sheaths of delicate, freely branched hyphae, branches of which may grow above their apices. Those of T. vermifera are otherwise naked; but in T. vermicularis many cystidia are at first encrusted with crystals which later are shed and replaced with hyphal sheaths. T. vermifera may be identified readily by the small, somewhat maculiform fructifications, large subulate cystidia, large irregular basidia, and peculiar spores. Basidia may bear one, two, or four spores, many of the sterigmata developing almost laterally. Spores are flexuous-naviculate, with proximal ends bluntly acuminate and apiculate, the distal tapering and flexuous. New Zealand collections differ from those of European specimens in the more irregular basidia and, especially, copious development of masses of crystals in the context. In some of the collections listed the context is stratose, composed of two or three vague layers.

DISTRIBUTION: North and South America, Europe, West Indies,. Japan, Australia, New Zealand.
HABITAT: Effused on bark of dead branches.
Identified readily by the yellow-ochre colour of the hymenial surface, which resembles new chamois leather, and masses of yellow-brown dichophyses in the context and hymenial layer. Spores, present in only two of the collections listed, in shape resemble those of V. fusispora (Fig. 54). Collections have somewhat larger and more densely branched dichophyses than those of specimens examined in Kew herbarium, but in other features agree closely.

HOST. Western Australia, Pemberton.
Hymenophore perennial, stratose, membranous, adherent, effused forming irregular areas to 15 x 5 cm, with numerous orbicular outlying islands; hymenial surface cream, alutaceous, or pallid ochre, even, not creviced; margin at first thinning out, when concolorous, adherent, in old specimens becoming cliff like or receding and tobacco-brown. Context ferruginous when old, 0.1-1.5 mm thick, composed of 1-9 obscure layers, basal layer narrow, of parallel cemented hyphae, intermediate layer of scanty erect hyphae, compound dichophyses and embedded crystals and spores; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, naked, with clamp connections. Gloeocystidia abundant in the hymenial layer, scattered and soon collapsed in the context, subclavate or fusiform, some projecting slightly, 32-85 x 6-8 µm. Dichophyses with stems arising from the base and traversing the context, producing at intervals lateral branches bearing dendriform branchlets with acute apices, some walls tinted near the base. Hymenial layer to 40 µm deep, a scanty palisade of basidia; paraphyses, gloeocystidia, and dichophyses: Basidia cylindrical, 22-32 x 5-6 µm, bearing 4 spores; sterigmata arcuate, delicate, 6-8 µm long. Paraphyses subclavate, scanty, 12-22 x 4-5 µm. Spores globose or subglobose, 6-8.5 µm, walls delicately and closely warted, hyaline, 0.5-1 µm thick.
DISTRIBUTION: Australia, Japan, New Zealand.
HABITAT: Effused on bark and decorticated wood of dead branches.
Spores are scattered freely both on the hymenial surface and among context hyphae. Walls of those on the surface are hyaline and contents are orange, whereas some in the lower layers of the context may be tinted. In size and numbers verrucae differ appreciably, in the collection from Leptospermum scoparium being scarcely visible under a magnification of x 600, whereas in specimens from Cordyline verrucae are about 0.5 µm long. Each compound dichophysis consists of a central stem which, arising from the base, traverses the context to the surface of the hymenium. At intervals lateral branches are produced, sometimes in whorls, bearing dendriform branches similar to the dichophyses of preceding species. In some collections walls of basal portions of the dichophyses are pallid yellow, the remainder being hyaline; in others they are hyaline throughout. All stain deeply with aniline blue. Collections match the type of 'Asterostromella' rhodospora in Kew herbarium, ex "Queensland, Nambour, Blackball Range". The species shows a general resemblance to Vararia pallescens (Schw.) R. & J. and V. peniophoroides (Burt) R. & J. From the former it may be separated by the different dichophyses and larger spores with coarser verrucae; from the latter by the different gloeocystidia and dichophyses, although spores are similar. Asterostroma epigaeum Lloyd from Japan was found to be of the same species.
TYPE LOCALITY: Blackball Range, Queensland.
Veluticeps setosa G. Cunn. 1963
MYRTACEAE. Tristania conferta: Queensland, Cunninghams Gap, type collection, P.D.D. herbarium, No. 17463.
Hymenophore apparently resupinate, coriaceous, adherent; effused forming irregular areas to 12 x 8 cm; hymeneal surface ferruginous or umber, velutinate, coarsely and deeply irregularly creviced; margin thinning out, definite, ferruginous, loosely attached. Context ferruginous, to 1 mm thick, a dense layer of parallel hyphae bordered by a cortex of parallel dark brown hyphae from which arise masses of short abhymenial hairs; skeletal hyphae 3-3.5 µm diameter, lumena almost capillary, ferruginous or reddish-brown, encrusted with granules of brown mucilage; generative hyphae 3-4 µm diameter, walls 0.2 µm thick, tinted or hyaline; collapsing, with clamp connections. Fascicles projecting to 160 µm, arising from the base of the subhymenium, 30-50 µm diameter, composed of 6-14 skeletal hyphae with rounded sometimes inflated apices, reddish-brown save at apices where lighter in colour, to 8 µm diameter, delicately verruculose, lumena capillary. Pseudosetae forming the bulk of the subhymenium, arranged in a dense palisade of 2-4 coloured zones, to 5 µm diameter, with rounded sometimes inflated apices, chestnut. Hymenial layer to 180 µm deep, a close palisade of basidia, paraphyses, fascicles, pseudosetae, and a deep subhymenium. Basidia clavate, 24-32 x 6-8 µm, bearing 4 spores; sterigmata slender, erect, to 6 µm long. Paraphyses rather scanty, subclavate, 18-25 x 5-6 µm. Spores fusiform or narrowly obovate, with rounded or acuminate apices, apiculate, 16-18 x 5-6 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Australia.
HABITAT: Decorticated dead branches.
Although part of the type from which the description has been drawn is resupinate, the presence of abundant abhymenial hairs suggests the species may be pileate and effused-reflexed as in V. berkeleyi. Specific features are the coriaceous hymenophore composed of a deep subhymenium of erect hyphae, deep intermediate tissue of parallel hyphae bordered by a dense, more deeply coloured cortex, fascicles arising from the base of the subhymenium, pseudosetae, and somewhat large spores. As in Duportella fulva the hymenium develops at an early stage, so that in the collection at hand basidia have been found only near margins, being collapsed over the greater part of the fructification. The pseudosetae and clamp connections in generative hyphae link the species with Duportella. The type collection was kindly donated by Mr W. Pont of the Queensland Department of Agriculture.

Veluticeps tabacina (Cooke) Burt 1920 [1919]
MYRTACEAE. Eucalyptus spp.: New South Wales, Moona, Walcha (Type collection, herb. Kew); Darling Downs, No. 1095, filed under Hydnum delicatulum (herb. Kew).
Hymenophore pileate, annual, ceraceous. Pilei cupulate or disciform, attached by a narrow base, elliptical or orbicular, 1-2 mm diameter, solitary or crowded; pileus exterior tomentose, ferruginous above, black below; hymenial surface plane or concave, pallid cream or tan, not creviced. Context tan, to 600 µm thick, of erect hyphae arising from a coloured cortex, pierced by fascicles and embedding masses of crystals; cortex to 130 µm thick, of densely intertwined ferruginous hyphae which are olivaceous below; walls coated with brown mucilage granules; generative hyphae 4-6 µm diameter, walls 0.25 µm thick, hyaline, without clamp connections. Fascicles arising from the base and projecting to 80 µm, to 50 µm diameter, composed of 20-80 hyphae 4-6 µm diameter, closely compacted, walls ferruginous, 1.5-2 µm thick, coated with coloured mucilage granules. Hymenial layer to 120 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 55-72 x 7-9 µm, bearing 4 spores; sterigmata erect, slender, to 6 µm long. Paraphyses cylindrical, some with acute apices, 40-65 x 6-7 µm. Spores narrowly obovate or suballantoid, with rounded apices and acuminate bases, apiculate, 20-24 x 8-10 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: Australia.
HABITAT: Crowded on bark of dead branches.
In appearance fructifications resemble small and crowded apothecia of a discomycete. The species was placed under Veluticeps by Burt because of the conspicuous brown fascicles and basidia, but could well be made the type of a separate genus, since in other features it has little in common with the type species of Veluticeps. Fascicles project to 80 µm, arise in the base of the context, are composed of many hyphae compacted together, with walls coloured and encrusted with granules of brown mucilage. They may be crowded, but are usually scattered, only half a dozen or so being present in a median section. Basidia are crowded in the compact hymenium and irregular in shape and size. The prominent cortex is composed of densely compacted, loosely intertwined hyphae similar to generative hyphae of the context, but with walls thickened and coloured, brown in the upper part, olivaceous below.
TYPE LOCALITY: Walcha, New South Wales, Australia.
