NEW SPEOIES OF NEW YOKE FUNGI. 



Trieholoma infantilis. 



Pileus thin, convex or nearly plane, even, minutely silky, moist 

 in wet weather, reddish-gray, the margin when young incurved 

 and whitish ; lamellae subdistant, plane or slightly veiitricose, 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 Trieholoma cozlata, 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 lamellae eroded. Trieholoma 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 ; lamellae 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 .0003 in. long. 



Plant single or caespitose, 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.
