50 The North American Species of Pholiota
Kauffman but Peck described it as having white flesh and a mild taste.
Pholiota tuberculosa (Fr.) Kummer is apparently very close to P. multifolia, but on the data available we do not regard them as synonyms.

Illustrations: Text figs. 3-4; pl. 4a.
Pileus (1) 2-5 (6) cm. broad, obtuse to convex, the margin incurved,
becoming broadly convex or nearly plane, at times with a low obtuse
umbo; surface dry, opaque, fibrillose, the epicutis becoming broken up
into small appressed to slightly recurved squamules, squamules around
the disc often small and inconspicuous, at times the extreme margin
lacerate-fibrillose or appendiculate from the remains of the thin veil;
color brilliant yellow to ferruginous yellow or finally ferruginous ("Mars
yellow" to "Cadmium-yellow" or "ochraceous-orange"). Context thin,
pliant, yellow. Odor and taste mild.
Lamellae moderately close to subdistant, broad, adnate, whitish in
small buttons but soon yellow and finally more or less cinnamon from
the spores, edges even but in age crenulate.
Stipe 2-5 (9) cm long, 2-5 (7) mm thick, curved or ascending, more
or less concolorous with the pileus, equal, tubular, apex clear yellow,
floccose fibrillose, becoming more or less rusty brown from handling. Veil
pale yellow, fibrillose, forming an evanescent fibrillose zone where it
breaks.
Spores 6-8.5 (9) X 3.5-4.5 (5) JL, rusty brown in KOH, smooth,
in face view elliptic to ovate, in profile somewhat bean-shaped, wall
scarcely thickened, no germ pore visible.
Basidia 20-26 x 4.5-6 /u, 4-spored, yellow in KOH or some with
rusty brown content, yellow pigment diffusing in the mount from the
hymenium. Pleurocystidia none. Cheilocystidia 24-42 (60) x 3-9 /,,
cylindric to narrowly clavate to more or less capitate and flexuous down
to the base, often in tufts, yellowish hyaline or with ochraceous to pale
tawny content, thin-walled, smooth. Caulocystidia 28-60 x 4-9,, similar
in shape to cheilocystidia but often more highly colored.
Gill trama parallel to somewhat interwoven, hyphal cells enlarged
in age, walls thin and yellowish in KOH, hyphae narrower near sub
