The North American Species of Pholiota

Stipe 5-9 cm long, 5-7 mm thick at apex, equal or slightly enlarged
downward, tubular to hollow, surface over lower portion pale yellowish
white from a thin coating of white fibrils extending to an evanescent zone
left by broken veil, yellowish beneath the fibrils, apex yellow and silky,
on aging becoming rusty brown from base upward and glabrescent.
Spore deposit yellow-brown ("snuff-brown"); spores 5-6 x 2.5-3 pU,
smooth, elliptic to oblong in face view, in profile subelliptic to slightly
bean-shaped; color pale ochraceous in KOH and Melzer's reagent; wall
thin, apex blunt but not truncate, no apical pore visible.
Basidia 4-spored, 16-18 x 4-5,u, yellowish in KOH. Pleurocystidia
32-47 x 10-15 pt, clavate-mucronate to fusoid-ventrocise, as revived in
KOH with a highly refractive central body. Cheilocystidia mostly chrysocystidia (like the pleurocystidia) but a few basidiole-like leptocystidia
present also. Gill trama subparallel, hyphae non-gelatinous, walls yellowish to brownish revived in KOH; subhymenium scarcely distinct. Pileus
epicutis a layer of appressed subgelatinous narrow (2-4 p, yellowish
hyphae with smooth to faintly asperulate walls; hypodermium of inflated
rusty ochraceous hyphae. Clamp connections present. All hyphae inamyloid.
HABIT, HABITAT, AND DISTRIBUTION: Caespitose to gregarious on decaying conifer logs, Pacific Northwest, in the fall, often late.
OBSERVATIONS: This species, like P. astragalina, is difficult to dry. It
discolors badly if even slightly overheated. The pale ochraceous viscid
pileus, numerous chrysocystidia and the fact that the spores are not
truncate characterize it.
