REPORT OF THE BOTANIST. OM 
Plant subceespitose, 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 7%. sp. 
Pileus thin, convex, obtuse, smooth, hygrophanous, reddish-brown or chest- 
nut color when moist, reddish-alutaceous when dry; lamelle narrow, close, 
adnexed, serrate on the edge, white; stem equal, substriate, slightly pruinose 
at the apex, white. 
Plant about 2’ high, pileus 6’—10' broad, stem 1” thick. 
Ground in wooded swamps. Root, Montgomery County. June. 
The serrated lamellz and white substriated stem will serve to distinguish 
this species from A. dryophilus. 
AGARICUS (COLLYBIA) ATRATOIDES 7. sp. 
Pileus thin, convex, subumbilicate, glabrous, hygrophanous, blackish- 
brown when moist, grayish-brown and shining when dry ; lamellze 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 subcespitose, about 1’ high, pileus 6-10" broad, 
stem .5’’-1” thick. 
Decaying mossy sticks and logs in woods. Gansevoort. Aug. 
The species belongs to the section Tephrophanz, and is apparently related 
to A. atratus. 
Agaricus (MycENA) LUTEOPALLENS 7. sp. 
Pileus thin, convex, smooth, striatulate on the margin when moist, bright 
yellow, becoming paler when dry; lamellz moderately close, subarcuate, 
yellow ; stem equal or slightly tapering upward, smooth, hollow, yellow, with 
yellow hairs and fibrils at the base. 
Plant single or czespitose, 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 parvulus by its 
subezspitose habit, and the yellow hairs at the base of the stem. 
Agaricus Epricuysium Pers. 
Decaying prostrate trunks of trees. Indian Lake. Aug. 
AGARIcUSs (PLUTEUS) TOMENTOSULUS 7. sp. 
Pileus thin, convex or expanded, subumbonate, dry, minutely squamulose- 
tomentose, white, sometimes pinkish on the margin; lamelle 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.
