Mycologia 
resembles C. atrialba and, like that species, reminds one of Colly- 
bia platyphylla. It is characterized by its innate-fibrillose, avel- 
laneous cap and glabrous or finely fibrillose stem. 
Clitocybe brunnescens sp. nov. 
Pileus rather thin, slightly depressed, rarely infundibuliform, 
reaching 4 cm. broad ; surface slightly viscid when moist, smooth, 
glabrous, dull-avellaneous, margin entire, concolorous ; context 
thin, whitish, with strongly farinaceous odor ; lamellae decurrent, 
subcrowded, narrow, dull-avellaneous, becoming dark-fuliginous, 
especially on the edges ; spores globose, smooth, hyaline, 3-3.5 ja ; 
stipe subequal, smooth, glabrous, concolorous above, whitish-to- 
mentose below, stuffed or hollow, 3-4 cm. long, 4-7 mm. thick. 
Type collected among sticks in woods near Seattle, Washing- 
ton, October 20-November i, 1911, IV. A. Miirrill dpp. This 
species is similar in form and color to C. cyathiformis, but differs 
decidedly in its spore characters, as well as in other important 
ways. 
Clitocybe cuticolor sp. nov. 
Pileus convex to subplane, thin, 3 cm. broad; surface smooth, 
glabrous, hygrophanous, dull-rosy-isabelline with a fulvous tint, 
margin entire, concolorous, incurved on drying; lamellae adnate, 
close, nearly plane, narrow, dull-rosy-isabelline ; spores broadly 
ellipsoid, smooth, hyaline, about 4.5 X 3-5 stipe eccentric, taper- 
ing upward from a bulbous base, fleshy, solid or stuffed, smooth, 
glabrous, rosy-isabelline, 4 cm. long, 7 mm. thick. 
Type collected on the ground in woods near Seattle, Washing- 
ton, October 20-November i, 1911, JV. A. Murrill 552. This 
species is colored throughout very much like the skin on the back 
of a man’s hand. Its affinities are with Tricholoma, reminding 
one of Tricholoma nudum, but the gills are distinctly adnate, not 
at all sinuate. 
Clitocybe griseifolia sp. nov. 
Pileus large, fleshy, convex to expanded or slightly depressed, 
usually solitary, reaching 9 cm. broad; surface slightly viscid 
when moist, smooth, glabrous, grayish-white, avellaneous, tinted 
with brownish-avellaneous at the center, margin thin, somewhat 
lobed, slightly paler, strongly incurved on drying; context white, 
fragrant; lamellae rather broad and close, short-decurrent or
