Hymenophore annual, membranous, adnate, effused forming small linear areas to 6 x 2 cm; hymenial surface tan or ochraceous, delicately pruinose, even, not creviced; margin thinning out, fibrillose, adnate, tan. Context to 500 µ thick, tan, of woven hyphae not organised into intermediate and basal layers; hyphal system monomitic; generative hyphae 3-5 µ diameter, walls 1-1.5 µ thick, clear fuscus, branched, sparsely septate, often inflated between septa, without clamp connexions. Hymenial layer to 65 µ deep, a close palisade of basidia and paraphyses. Basidia cylindrical, 30-55 x 6-7 µ, 2-4-spored; sterigmata arcuate, slender, to 8 µ long. Paraphyses subclavate, about half the length and diameter of the basidia. Spores obovate, elliptical, a few subglobose, with apices rounded and bases apiculate, 7-9 x 5-6.5 µ, walls olivaceous, smooth, 0.5 µ thick.

DISTRIBUTION: New Zealand.

HABITAT: Effused on decorticated wood.

Hymenophorum annuum, membranaceum, adnatum, effusum; superficies hymenii alutacea vel ochracea, tenuiter pruinosa, aequa, fibrilloso, adnato, alutacea margine. Contextus alutaceus. Hypharum systema monomiticum; hyphae generatoriae hyalinis, tenuibus parietibus, enodulosae. Basidia cylindricalia, eminentia, 30-55 x 6-7 µ. Sporae obovatae, ellipticae vel aliquot subglobosae, apiculatae, 7-9 x 5-6.5 µ, olivaceis parietibus, 0.5 µ crassis.

Specific features are the monomitic hyphal system with sepia or fuscous coloured thick-walled hyphae, small spores and rather slender, projecting, cylindrical basidia. Spores are the smallest of the species described.
