Plant subcaespitose, 2 , -3 / high, pileus 1'— 1.5' broad., stem 2"-3" thick. 



Decaying half-buried wood. Knowersville. May. 



At first sight the young pileus is suggestive of the pileus of Hygrophorus 

 conicus, both in shape and color. When dry the color is pallid or subochra- 

 ceous. 



Agaricus (Collybia) lentinoides n. sp. 



Pileus thin, convex, obtuse, smooth, hygrophanous, reddish-brown or chest- 

 nut color when moist, reddish-alutaceous when dry ; lamellae narrow, close,, 

 adnexed, serrate on the edge, white ; stem equal, substriate, slightly pruinose 

 at the apex, white. 



Plant about 2' high, pileus G'-IO 1 ' broad, stem 1" thick. 



Ground in wooded swamps. Root, Montgomery County. June. 

 The serrated lamellae and white substriated stem will serve to distinguish 

 this species from A. drpophilus. 



Agaricus (Collybia) atratoides n. sp. 



Pileus thin, convex, subumbilicate, glabrous, hygrophanous, blackish- 

 brown when moist, grayish-brown and shining when dry ; lamellae rather broad, 

 adnate, subdistant, grayish- white, often venulose-connected and transversely 

 marked above with slender veins ; stem equal, hollow, smooth, grayish-brown, 

 with a whitish tomentum at the base ; spores nearly globose, about .0002' 

 across. 



Plant gregarious or subcaespitose, about 1' high, pileus 6"-10 ' broad, 

 stem ,5"-l" thick. 



Decaying mossy sticks and logs in woods. Gansevoort. Aug. 



The species belongs to the section Tephrophanae, and is apparently related 



to A. atratus.

Agaricus (Mycena) luteopallens n. sp. 



Pileus thin, convex, smooth, striatulate on the margin when moist, bright 

 yellow, becoming paler when dry ; lamellae moderately close, subarcuate, 

 yellow ; stem equal or slightly tapering upward, smooth, hollow, yellow, with 

 yellow hairs and fibrils at the base. 



Plant single or caespitose, 2' high, pileus 3' ; -6" broad, stem about 1" thick. 



Among fallen leaves in woods. Adirondack Mountains. Aug. 

 This species may be distinguished from Hygrophorus par cuius by its 

 subcaespitose habit, and the yellow hairs at the base of the stem. 



Agaricus Epichysium Pers. 



Decaying prostrate trunks of trees. Indian Lake. Aug. 



Agaricus (Pluteus) tomentosulus n. sp. 



Pileus thin, convex or expanded, subumbonate, dry, minutely squamulose- 

 tomentose, white, sometimes pinkish on the margin ; lamellae rather broad, 

 rounded behind, free, crowded, white, then flesh-colored ; stem equal, solid,, 

 striate, slightly pubescent or subtomentose, white; spores subglobose, .0003' 

 in diameter, generally containing a single large nucleus.
