Mycologia 5(4): 223. 1913.
Common Name: none
Cap 5-15 cm broad, at first broadly conic with an inrolled margin, expanding to nearly plane, the margin then wavy and sometimes uplifted; surface viscid when moist, pallid to cream, becoming streaked, pale to medium cinnamon-brown, the margin lighter; in age darker brown overall and often innately fibrillose; flesh white, moderately thick, firm; odor and taste farinaceous.
Gills notched, broad, close, pallid, darkening slightly in age, the edges bruising or discoloring brown.
Stipe 6-13 cm tall, 1-4.5 cm thick, varying from stout to "leggy," stuffed at maturity; equal to enlarged at the base; surface moist, white, finely striate at the apex, fibrillose brown over a pallid background below, bruising and discoloring brown in age; flesh white unchanging; veil absent.
Spores 5-6 x 4-4.25 µm, elliptical, smooth; spore print white.
Scattered to gregarious, or clustered under oak, especially coast liveoak (Quercus agrifolia); fruiting from late fall to mid-winter.
This oak-loving Tricholoma is often found fruiting partially buried in duff. When immature, the cap is nearly white, but soon develops pinkish to cinnamon brown streaks, the margin remaining pallid. In age the pileus becomes cinnamon-brown to medium-brown overall and innately fibrillose. Tricholoma manzanita also has a pallid cap when young but is more orange-brown at maturity, has a pale yellow stipe apex, lacks a farinaceous odor, and as the species name suggests, occurs under species of Arctostaphylos. Although Tricholoma dryophilum is typically associated with Quercus agrifolia, we have found two collections under Eucalyptus.
