Subiculum annual, delicate, arachnoid, yellow, effused forming linear areas to 8 x 2 cm. Pilei crowded, not confluent, subglobose or cupulate, 100-300 µm diameter, attached by narrow bases; pileus exterior finely radiate-striate, tomentose, abhymenial hairs filiform, 2.5-3 µm diameter, slightly tortuous, erect, walls light yellow brown, finely crystal encrusted; margin strongly inturned, obscuring the hymenium, tomentose, lacerate; hymenium even, grey, concave. Context white, to 50 µm thick, of radiately arranged densely compacted parallel hyphae; generative hyphae 2.5-3 µm diameter, walls 0.25 µm thick, hyaline. Hymenial layer to 40 µm deep, a close palisade of basidia and paraphyses. Basidia subclavate, 16-24 x 6-8 µm, bearing 4 spores; sterigmata erect, slender, to 5 µm long. Paraphyses subclavate, 12-20 x 5-6 µm. Spores globose or subglobose, apiculate, 6-8 x 5-6 µm, walls smooth, hyaline, 0.25 µm thick.

DISTRIBUTION: North America, New Zealand.

HABITAT: Crowded on bark of dead stems and branches.

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.
