ing, avellaneons on the small umbo, margin entire, concolorous, 
inflexed on drying; lamellae decurrent, rather broad and distant, 
white, becoming discolored on drying; spores ellipsoid, smooth, 
hyaline, 5-6 X 2. 5-3. 5 /a ; stipe equal, smooth, pruinose, especially 
above, white changing to pale-fumosus on drying, hollow, 3-4 
cm. long, 2-3 mm. thick. 
Type collected in humus in woods near Seattle, Washington, 
October 20-November i, 1911, W. A. Murrill ^16. 
Clitocybe variabilis sp. nov. 
Pileus fleshy but rather thin, plane or slightly depressed, rarely 
umbonate when young, gregarious, reaching 6 cm. broad ; sur- 
face dry, smooth, glabrous, white, margin thin, usually entire, 
concolorous ; lamellae narrow, usually more or less crowded, de- 
current, white ; spores ovoid, smooth, hyaline, uninucleate, about 
6X4 /a; stipe tapering upward from a thickened base, smooth, 
glabrous, white, whitish-mycelioid at the base, hollow, reaching 
6 cm. broad and 8 mm. thick, scarcely 3 cm. long in one collection. 
Type collected in humus in woods, near Mill City, Oregon, 
November 9, 1911, W. A. Murrill 797. Also collected on the 
ground in fir forests near Corvallis, Oregon, November 6-1 1, 
1911, IV. A. Murrill 8<^y, and in a similar locality near Salem, 
Oregon, January, 1911, Morton E. Peck. This species varies 
greatly in the length of the stipe and the closeness of the gills. 
The specimens collected near Corvallis differ so greatly from the 
types in these two characters as to constitute a distinct variety, 
which may be called Clitocybe variabilis brevipes. 
Clitocybe violaceifolia sp. nov. 
Pileus convex, somewhat gibbous, solitary, 3 cm. broad; sur- 
face slightly viscid when moist, smooth, glabrous, grayish-violet 
tinted with brown at the center, margin entire, slightly paler ; 
lamellae very narrow, adnexed to slightly decurrent, rather 
crowded, arcuate, pale-violet; spores ellipsoid, smooth, hyaline, 
X 3 - 5 “ 4 - 5 j stipe equal, fleshy, solid, smooth, glabrous, 
grayish-violet, mycelioid at the base, 3 cm. long, 6 mm. thick. 
Type collected on decaying wood near Salem, Oregon, January, 
1911, Morton E. Peck.
