Description: 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.
Habitat: HABITAT: Crowded on bark of dead stems and branches.
Distribution: DISTRIBUTION: North America, New Zealand.
Notes: 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.
