The smooth stem, the pale fibers on the cap that become brownish
with age, the thick ring, and the yellowing flesh in the stem base characterize
this woodland, West-Coast species. It often has a phenolic odor, best detected
by crushing the flesh in the base of the stem--but the odor can be hard to
detect in some collections.
Description:
Ecology: Saprobic; growing alone, scattered, gregariously, or in
fairy rings in conifer and hardwood forests, frequently where woody debris is
present; fall and winter; on the West Coast from British Columbia to
California.
Cap: 6-15 cm; convex, becoming broadly convex or flat; dry; fairly
smooth or, more commonly, with appressed fibers that are initially pale but
darken to brown or reddish brown as the mushroom matures; whitish to pale
pinkish brown beneath the fibers.
Gills: Free from the stem; close; whitish at first, becoming
pinkish and, eventually, brown.
Stem: 7-20 cm long; 1-2.5 cm thick; equal or slightly tapered
toward apex (sometimes with a swollen base); smooth; whitish, becoming pale
brownish with age; with a persistent, thick ring.
Flesh: Thick and white throughout; often yellowing on exposure,
especially in the stem base. A pinkish stage may follow the yellowish stage in
the cap and upper stem.
Odor and Taste: taste not distinctive; odor usually phenolic,
especially when the stem base is crushed.
Chemical Reactions: Cap yellow with KOH.
Spore Print: Dark brown.
Microscopic Features: Spores 4.5-6 x 3-4 ยต; elliptical; smooth. Pleurocystidia absent; cheilocystidia not
easily distinguished from basidioles.
