UNKNOWN HOSTS. Tasmania, type collection of Thelephora viridis (herb. Kew); type collection of Hypochnus chlorinus (herb. Kew). New South Wales, Garie Beach.
Hymenophore annual, membranous, fragile, loosely attached, effused forming small irregular areas to 6 x 1.5 cm; hymenial surface finely granulose, yellow-green, ferruginous when dry, sparsely creviced; margin thinning out, concolorous, loosely attached, fibrillose. Context tinted yellow, to 120 µm thick, basal layer of a few repent hyphae to 5 µm diameter, walls tinted, intermediate layer of mainly erect hyphae 3 µm diameter; generative hyphae 3-4.5 µm diameter, walls 0.2 µm thick, some bearing yellow granules of mucilage, hyaline, beneath the hymenium, tinted yellow in the base, branched, septate, with clamp connections. Hymenial layer to 35 µm deep, a loose palisade of clusters of basidia and paraphyses. Basidia clavate, 16-20 x 4.5-5 µm, bearing 4 spores; sterigmata arcuate, slender, to 4 µm long. Paraphyses subclavate, 12-16 x 3.5-4 µm. Spores globose or subglobose, apiculate, 4.5-6 µm diameter, walls not sinuate, golden-yellow, finely sparsely verruculose, 0.2 µm thick, spines to 0.5 µm long.
DISTRIBUTION: Tasmania, Australia.
HABITAT: Bark and decorticated dead branches.
T. viridis may be recognised readily by the yellow-green granulose surface, delicate context, small basidia, and small subglobose spores. Context hyphae of the base are 4.5-5 µm diameter with walls tinted yellow, 2.5-3 µm diameter and hyaline in the bulk of the context. A few in the base bear irregular granules of yellow mucilage. Spores are globose or subglobose, walls are golden yellow, not sinuate, and covered with scanty verrucae about 0.5 µm long. Only the three collections listed are known. On the type sheet of 'Thelephora' viridis is placed a specimen from New Zealand which is part of the type of Coniophora viridis.
TYPE LOCALITY: Tasmania.
