have thinner walls, the FeSO4 reaction is bright green rather than dark
olive, and its spores are a darker brown in KOH.

Illustrations: Text figs. 319-321.
Pileus 3-6.5 cm broad, convex, sordid tawny to rusty, marginal portion pallid or yellowish and appressed-scaly, the scales darker, viscid,
fibrillose with fugacious veil-remnants on the margin. Context grayish
white; odor and taste not distinctive.
Lamellae adnate, white or pallid, becoming brownish ochraceous,
close, thin, medium broad.
Stipe 5-7.5 cm long, 4-8 mm thick, whitish to pale yellowish, apex
pruinose, the base staining rusty in age, more or less fibrillose-scaly, solid.
Veil buff or yellowish white, copious, forming an evanescent fibrillose
ring.
Spores 6-7.5 x 4-4.5 JL, smooth, apical pore absent to very minute.
Shape in face view elliptic to ovate, in profile obscurely bean-shaped to
somewhat inequilateral, color revived in KOH pale golden tawny to
ochraceous tawny, in Melzer's reagent paler ochraceous tawny to dull
pale ochraceous; wall about 0.25 u, thick.
Basidia 4-spored, 18-24 X 5-6.5 /L, narrowly clavate, yellowish in
KOH and in Melzer's reagent. Pleurocystidia abundant 50-75 x 8-12
(15) /i, fusoid-ventricose with obtuse apex, outline of neck often flexuous
to almost contorted, smooth or with some adhering gelatinous material,
wall thick in ventricose portion (~ 2 /i), thinning out in neck, neck
filled with a plug of hyaline to ochraceous homogeneous material, some
of this in some cells extruded in the form of a cap over apex of the cell,
walls hyaline to yellowish in KOH. Cheilocystidia subcylindric to fusoid
ventricose, 28-46 (55) x 7-12 /, walls thickened in most, with mucilaginous adhering material in many and content mostly ochraceous in KOH.
Caulocystidia present at apex of stipe, 40-60 x 10-16 FL, scattered, elliptic-pedicellate to fusoid-ventricose, walls thin to somewhat thickened.
Cheilocystidium-like cells also present in the caulohymenium.
Gill trama with a central strand of floccose-interwoven hyphae
yellowish in KOH, thin-walled, smooth and hyphal cells greatly inflated;
subhymenium a gelatinous layer of narrow interwoven hyphae hyaline
to faintly yellowish revived in KOH. Pileus cutis a gelatinous pellicle of
narrow (2-5 /z) encrusted hyphae, in age the collapsing hyphae transversely crinkled or creased; hypodermial region of tawny floccose hyphae
4-12,/ (or more) in diam., the incrustations as annular zones, plates etc.,
and ochraceous tawny in KOH. Context hyphae thin-walled mostly
smooth, walls hyaline to yellowish in KOH, cells greatly inflated at times.
Clamp connections present. All hyphae inamyloid.
