Hymenophore annual, membranous, adnate, effused forming numerous small elliptical colonies in bark crevices, 1-5 x 0.5-1.5 cm; surface white, velutinate, scantily creviced; margin thinning out, arachnoid, adnate, white. Context white, to 60 µ thick, basal layer delicate, of a few parallel hyphae, intermediate layer of scanty, mainly upright, short-celled hyphae; generative hyphae 3-3.5 µ diameter, walls 0.2µ thick, hyaline, often crystal coated, branched, freely septate, with small, inconspicuous clamp connexions. Hymenial layer to 20 µ deep, of scanty basidia, paraphyses and abundant cystidia. Basidia subclavate, 12-16 x 5-6 µ, soon collapsing, 4-spored; sterigmata slender, to 4 µ long. Paraphyses subclavate, shorter and narrower than the basidia. Cystidia arising from the base of the intermediate layer and projecting for the greater part of their length, subulate with slightly inflated bases and long-acuminate apices, 110-190 x 10-14 µ, thick-walled, rugulose-roughened or etched, sometimes bearing a few crystals and enmeshed in a delicate hyphal sheath. Spores broadly elliptical, ovate, obovate, sometimes flattened on one side, 5-6 x 4-5 µ, walls finely verruculose, hyaline, 0.5 µ thick, soon collapsed.
DISTRIBUTION. New Zealand.
HABITAT. Effused in bark crevices on dead branches.
Hymenophorum annuum, membranaceum, adnatum, ellipticum, 1-5 x 0.5-1.5 cm; superficie alba, velutina, rimosa. Hyphae contextus fibulatae, 3-3.5 µ diam., nudae. Basidia subclavata, 12-16 x 5-6 µ, 4 sporis. Cystidia. subulata, eminentia, 110-190 x 10-14 µ, caelata, velut si crystallis tenuibus tecta. Sporae late ellipticae vel obovate, 5-6 x 4-5 µ, subtiliter verruculosae, hyalinae.
Close to P. gladiola, differing in the smaller basidia, smaller elliptical spores with finely verruculose walls, and absence of paraphysate hyphae.
Griselinia lucida Forst. Auckland: Glen Esk Valley, Piha, May, 1951, J.M. Dingley, type collection, P.D.D. herbarium, No. 11442.
CORNACEAE. Griselinia lucida: Auckland, Glen Esk Valley, Piha, 250 m, type collection, P.D.D. herbarium, No. 11442
Hymenophore annual, membranous, adherent, effused forming numerous small elliptical colonies in bark crevices, 1-5 x 0.5-1.5 cm; hymenial surface white, velutinate, scantily creviced; margin thinning out, arachnoid, white, adherent. Context white, to 60 µ thick, basal layer delicate, of a few parallel hyphae, intermediate layer of scanty, mainly erect, short-celled hyphae; generative hyphae 3-3.5 µ diameter, walls 0.2 µ thick, often encrusted, freely septate, with clamp connections. Cystidia arising from the base of the intermediate layer and projecting for the greater part of their length, subulate with slightly inflated bases and long-acuminate apices, 110-190 x 10-14 µ, thick-walled, rugulose-roughened or etched, sometimes bearing a few crystals and enmeshed in delicate hyphal sheaths. Hymenial layer to 20 µ deep, a loose palisade of basidia, paraphyses, and cystidia. Basidia subclavate, 12-16 x 5-6 µ, bearing 4 spores, soon collapsing; sterigmata slender, to 4 µ long. Paraphyses subclavate, 8-12 x 4-5 µ. Spores broadly elliptical, ovate, obovate, sometimes flattened on one side, 5-6 x 4-5 µ, walls finely verruculose, hyaline, 0.5 µ, thick, soon collapsing.
TYPE LOCALITY: Glen Esk Valley, Auckland, New Zealand.
DISTRIBUTION: New Zealand.
HABITAT: Effused on bark of dead branches.
Close to T. gladiola, differing in the smaller basidia, smaller elliptical spores with finely verruculose walls, and absence of paraphysate hyphae.

Litschauerella hastata (G. Cunn.) Stalpers & P.K. Buchanan 1991

Basidiome membranaceous, white. Hyphae thinwalled; clamped at all septa, encrusted in the subiculum. Cystidia projecting, subulate, thickwalled (wall crystal-covered), swollen at the base, c. 130-185 x 10-15 µm, with climbing hyphae. Mature basidia not seen. Spores hyaline, verrucose, ellipsoid to obovoid, 6-7.8 x 5-5.8 µm, not amyloid. The ornamentation of the wall consists of irregularly arranged, thin, erect, angular (often rectangular) projections; it is distinct in Melzer's reagent but only faintly visible in KOH suggesting partial dissolution.
The species is close to Litschauerella gladiola, as recognised by Cunningham (1955, 1963) and Weresub (1961). The rather small ellipsoid spores and the relatively coarse ornamentation distinguish it from both L. clematitis and L. gladiola. The latter species also has encrusted cystidioles. Weresub (1961) suggested that the poor condition of the holotype of L. hastata "could be ascribed to growth of P. clematitis under unfavourable circumstances of some kind". However, a more recent collection of L. hastata (PDD 48739, Fig. 11), agrees with the holotype (Fig. 10) in spore characters. Studied with SEM, the erect, angular projections of L. hastata (Fig. 10-11) are different from the rounded warts on spores of L. gladiola and also from the cubical projections of L. clematids spores. It may be identical with Litschauerella sp. Bourdot 32350 (= L. Corbière 5) as described by Eriksson & Ryvarden (1976).
Holotype: on Griselinia lucida Forst. f., New Zealand, Auckland, Piha, Glen Esk Valley, coll. J.M. Dingley, 12 May 1951 (PDD 11442).
