obscurely inequilateral; color in KOH pale cinnamon, in Melzer's reagent
paler, cinnamon to ochraceous; wall about 0.25 J thick.
Basidia 16-22 X 5-6 a, 4-spored, yellowish to hyaline in KOH and
yellowish in Melzer's reagent. Pleurocystidia 36-58 (65) x 7-15 /, fusoidventricose witli oltuse apex, smooth, thin-walled, content in the neck in
most amber-brown to raw-sienna and appearing wrinkled to striate or
near apex with needle-like crystals, some hyaline and homogeneous.
Cheilocystidia 17-26 X 4-9 /l, clavate to fusoid-ventricose, hyaline, thin
walled, content lhomogeneous and hyaline. Caulocystidia (none found
but very little material available for examination).
Gill trama with a floccose hyaline central strand of hyphae with
elongated cells 5-8 /x in diam. (inflating finally to larger) with smooth
1hyaline walls; subll)ymenium a gelatinous layer of narrow lhyaline hyphae
sul)parallel to interwoven. Pileus cutis a thick gelatinous pellicle of
interwoven narrow (1.5-4 /j) ochraceous to hyaline smooth hyphae;
lhypodermlial region rusty-fulvous from incrusted floccose hyphae of
variouls diameters (to 15 /u ~ at times). Context hyphae yellowish to
hyaline, tlin-walled, smooth, interwoven and cells more or less inflated.
Clampl connections present. All hyphae inamyloid.
HABIT, HABITAT, AND DISTRIBUTIO(N: On soil, California, January
Type studied.
OBSIERVATIONS: Tlle description of microscopic features in the above
description are taken from the type collection. This species has a brightly
colored pileus even in the (dried condition lbut is somewhat similar to
P. Iighlandensis in stature aside from the tlicker stipe and the features
placing it in Subgenus Flan7llloidcs. It differs further from P. highlanlcnsis in not growing on I1lrned ground, in l)righter colored lamellae
wlhen young and scaly stipe (as described by Murrill).

Illustrations: Text figs. 406-407; pl. 82.
Pileus 2-6 cm broad, viscid, convex to conic or campanulate, then
umbonate, at first "Kaiser-brown," then "tawny," or "cinnamon-rufous,"
"mars-orange" to "Sanford's-brown," disc "burnt-sienna" (bright ferruginous to orange-ferruginous) viscid, margin even, incurved and
appendiculate, glabrous except for evanescent veil-remnants. Context
"light ochraceous-salmon" to pale yellow, moderately thick in the disc,
but thin on margin; odor and taste mild.
Lamellae adnate to adnexed or emarginate, "straw-yellow" to
"Naples-yellow," finally "snuff-brown," broad, ventricose, close, or
crowded, edges at first fimbriate, finally even.
Stipe 4-8 cm long, 2-8 mm thick, apex pallid or yellow, dark or
dingy olive below, fibrillose, moist, stuffed, then hollow, often compressed,
