NEW SPECIES OF NEW YORK FUNGI. 
Tricholoma infantilis, 
Pileus thin, convex or nearly plane, even, minutely silky, moist 
in wet weather, reddish-gray, the margin when young incurved 
and whitish ; lamellz subdistant, plane or slightly ventricose, often 
eroded on the edge, whitish ; stem short, equal or tapering upward, 
hollow, slightly silky, colored like the pileus or a little paler; spores 
broadly elliptical, .0003 to .00035 in. long, .0002 to .00025 broad, 
often containing a shining nucleus. 
Plant gregarious, pileus 4 to 12 lines broad, stem 1 to 1.5 in, 
high, 1 to 2 lines thick. 
Gravelly soil in fields. Sandlake. June. 
This is a very small species belonging to the section SERICELLA and 
related to Tricholoma ccelata, from which it is distinguished by its 
different color and the absence of an umbilicus from the pileus. 
This is sometimes papillate, and both it and the stem imbibe moist- 
ure. The latter is fleshy-fibrous, and its cavity is very small. In 
the larger specimens the margin of the pileus is often wavy, and the 
edge of the lamelle eroded. Tricholoma Hebeloma, a closely allied 
species, may be distinguished by its more conical pileus, slender 
habit and smaller spores. 
Clitocybe basidiosa. 
Pileus rather thin, convex, then expanded and umbilicate or cen- 
trally depressed, glabrous, hygrophanous, grayish-brown and striatu- 
late on the margin when moist, dingy-white or grayish-white when 
dry, flesh whitish ; lamelle arcuate or nearly plane, thick, distant, 
adnate or slightly decurrent, whitish with a violaceous tint; stem 
equal or slightly thickened above, glabrous, firm, whitish or pallid ; 
spores subglobose, .00016 to .0002 in. long, basidia elongated, .0024 
in. long, bearing spicules .0008 in. long. 
Plant single or cespitose, 1 to 2 in. high, pileus 16 to 18 lines 
broad, stem 1 to 2 lines thick. 
Woods and swamps. Sandlake and East Berne. August.
