Agaricus (Crepidotus) Herbarum, Peck. 
Pileus thin, at first resupinate, with the margin incurved, clothed with white 
down, at length somewhat reflexed, less downy, the margin spreading ; lamellae 
narrow, not crowded, diverging from a naked lateral or eccentric point, white, 
then tawny ; spores slightly curved, .00028' x .00014’. 
Pileus 2''-4'' broad. 
Dead stems of herbs. North Greenbush. October. 
Agaricus (Psalliota) diminutivus, Peck. 
Pileus expanded or centrally depressed, sometimes with a slight umbo, dry, 
alutaceous, the disk rosy-brown and spotted with small appressed silky scales ; 
lamellae close, thin, free, ventricose, brownish-pink, becoming black; stem 
equal or slightly tapering upward, hollow or stuffed with a whitish pith, 
smooth, pallid; annulus thin, persistent, white; spores .0002' x .00015’. 
Plant 1.5'-2' high, pileus 1'-1.5' broad, stem 1/-2” thick. 
Ground in woods. Croghan. September. 
Sometimes the whole pileus is reddish-brown. The flesh is quite 
brittle. 
Agaricus (Stropharia) Howeanus, Peck. 
Pileus convex, then expanded, fragile, smooth, subumbonate, yellowish ; 
lamellae close, thin, rounded behind, eroded on the edge, whitish becoming 
ferruginous-brown; stem smooth, hollow, slightly thickened at the base; 
annulus thin, fugacious, sometimes adhering to the margin of the pileus; flesh

Center. June. 
The surface of the pileus sometimes cracks into areas. The taste 
is bitter. The color of the spores is not a decided brown, and the 
plant might with almost equal propriety be referred to the subgenus 
Phohota.

Pileus hairy-squamulose, hygrophanous, grayish-brown when moist, gray 
when dry; lamellae narrow, rounded at the stem, gray, then brown; stem 
short, firm, equal, hollow, slightly hairy-squamulose and colored like the 
pileus ; spores subelliptical, nucleate, .00025' long.
