The North American Species of Pholiota

gin even, entire, incurved when dry. Context thin, pallid; odorless, taste
mild.
Lamellae adnate with decurrent tooth, ferruginous at maturity, inserted, broad, medium distant, entire.
Stipe about 5 cm long, 7 mm thick, subequal, smooth, glabrous, pale
yellowish above, fulvous below.
Spores 6-7.5 x 3.8-4.5 /I, more rarely 8-9 X 5 /j,, elliptic or more
rarely subovate in face view, inequilateral in profile; smooth; germ pore
minute. Basidia 22-25 X 5-6,/, 4-spored. Pleurocystidia 48-65 x 8-10 Ab,
ventricose, usually colorless, sometimes brown, apices sometimes with an
exudate; cheilocystidia 30-58 X 8-10 uA, similar.
Gill trama with a central stratum of hyphae subparallel and 3-5 /L
broad. Pileus trama radial. Cuticle a gelatinous zone of loose, narrow
(1-2.5,u broad), colorless hyphae, resting on a hypodermium of incrusted, brown hyphae. Clamp connections present. Caulocystidia none.
Pileus and gill trama pale yellowish in KOH; dark dingy brown in
Melzer's reagent (data by Hesler).
HABIT, HABITAT, AND DISTRIBUTION: On soil, humus, and rotten logs,
Florida, California, and Idaho, August and December. Type studied.
OBSERVATIONS: This may be too close to P. spumosa to recognize it
as a separate taxon, but the ferruginous gills may be distinguishing features, the gill color no doubt reflects a similar color in the spore deposit
though this remains to be established.

Pileus 3-6 cm broad, conic with an incurved margin, expanding to
conic-campanulate, or conic umbonate, the umbo acute, surface viscid,
fibrillose-streaked (virgate) beneath the viscid pellicle, margin with thin
patches of the fibrillose remains of the veil, "tawny-olive" on disc "honeyyellow," on margin or at extreme edge "Reed's yellow." Context pliant,
thin except on the disc, near "honey-yellow" (more dingy than gills);
odor none, taste mild.
Lamellae broadly adnate becoming subdecurrent, moderately close,
3 tiers of lamellulae, moderately broad (5-6 mm near stipe) tapered to
