Hymenophore annual, membranous, adherent, effused forming linear areas 10-30 x 2-4 cm; hymenial surface cream, then alutaceous or buff towards the centre, spinose with projecting fascicles, at length closely areolately creviced; margin thinning out, white, fibrillose, adherent. Context white, 100-150 µ thick, basal layer compact, of mainly repent hyphae, intermediate layer of loosely intertwined hyphae; generative hyphae 2-3.5 µ diameter, walls 0.2 µ thick, with clamp connections. Dendrophyses with stems 3-5 µ diameter, scantily branched near apices and sometimes inflated at junctions of branches, at first naked, soon encrusted with fine crystals. Gloeocystidia absent. Fascicles arising in the base of the subhymenium or upper part of the context, projecting for the greater part of their length, 160-230 x 65-90 µ, composed of 100-350 filiform hyphae 3-4 µ diameter, with naked walls. Hymenial layer a close palisade of basidia, paraphyses, and dendrophyses interrupted by fascicles. Basidia subclavate, soon collapsing, 50-64 x 11-14 µ, bearing 4 spores; sterigmata arcuate, stout, to 16 µ long. Paraphyses clavate, 25-40 x 6-9 µ. Spores obovate or sometimes limoniform, strongly apiculate, 13-16 x 8-10 µ, walls smooth, hyaline, 0.25 µ thick, nonamyloid, soon collapsing.

TYPE LOCALITY: Carterton, Wellington, New Zealand.
DISTRIBUTION: New Zealand.

HABITAT: Effused on bark or wood of dead branches and stems.

Hymenophorum membranaceum, adnatum, effusum; superficie cremea deinde alutacea vel bubalina, plerumque velutinata, dense areolato rimosa. Hyphae generatoriae fibulatae, 2-3.5 µ diam. 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).
