New species of fungi 
CHARLES Horton PEcK 
Collybia subsulphurea_ 
Pileus fleshy but thin, somewhat tough, reviving under the 
influence of moisture, broadly convex, often becoming centrally 
depressed, glabrous, sulfur-yellow, sometimes tinged with pink or 
pale tan-color in the center, flesh hygrophanous, white when dry, 
odor strong, fungoid; lamellae thin, narrow, close, rounded be- 
hind, adnexed or nearly free, pale sulfur-colored or whitish; stem 
rather long, tough, glabrous, hollow, tapering downwards, even 
when moist, striate-sulcate when dry, sulfur-colored or pallid; 
Spores elliptic, 6 # long, 3 # broad. 
Pileus 2.5-6 cm. broad; stem 5-12 cm. long, 2-6 mm. thick. 
Cespitose. Among fallen leaves under oak trees. Stockton, 
Kansas. June. E. Bartholomew. 
Closely allied to C. dryophila (Bull.) Fr., but larger, more 
cespitose, of a different color, with a strong odor and smaller 
‘Spores, 
Omphalia vestita 
Pileus thin, membranaceous, convex nearly plane or slightly 
depressed in the center, minutely pruinose or tomentose, white ; 
lamellae few, very distant, adnate or decurrent, white or whitish ; 
Stem slender, short, solid or stuffed, pruinose-pubescent either 
wholly or on the basal half only, whitish or pallid, often becoming 
brownish with age ; spores subglobose, 4-5 /« in diameter. 
Pileus 2-3 mm. broad; stem 6-10 mm. long, 0.5-I mm. 
thick, 
Decaying vegetable matter in damp places. Horseshoe island, 
Ontario, Canada. August. C. Guillet. 
This is a very small white species closely related to O. znteg- 
rella Pers. and O. pusillissima Peck, from both of which it is sep- 
arated by the minute tomentose covering of the pileus. 
Omphalia curvipes 
Pileus submembranous, convex, umbilicate, glabrous, moist, 
Sometimes obscurely striate on the incurved margin, brown, gray- 
Ish-brown or dark-gray, sometimes paler in the center when dry ; 
lamellae thin, moderately close, arcuate, adnate or slightly decur-
