REPORT OF THE BOTANIST. 
Agaricus (HypHonoma) uirtosquamutosus Peck. 
Pileus firm, convex or expanded, hairy-squamulose, hygrophan- 
ous, grayish-brown when moist, gray when dry; lamelle narrow, 
rounded at the stem, gray, then brown; stem short, firm, equal, 
hollow, slightly hairy-squamulose and colored like the pileus ; 
spores subelliptical, cymbiform, nucleate, .00025' long. 
Plant 1’ high, pileus 6"-10" broad, stem scarcely 1" thick. 
Prostrate trunks of maple trees in woods. Portville. September 
The minute hairy tufts of the pileus are similar in appearance to 
those on A. melleus. 
AGARICUS HIASCENS £7. 
Damp ground under willows. West Albany. June. 
CoprINvs VARIEGATUS Peck. 
Pileus fleshy, thin, fragile, oblong-ovate, then campanulate, 
obtuse, hygrophanous, pale watery-brown when moist, whitish or 
cream color when dry, variegated by scales or patches of a super- 
ficial ochraceous tomentum, the margin finely striate; lamelle 
lanceolate, crowded, ascending, free, white, then rosy-brown, finally 
black ; stem equal, brittle, hollow, white, at first peronate-annulate, 
then floccose-pruinose, with white branching root-like threads at 
the base; spores subelliptical, .00033' long. 
Plant densely cespitose, 8-5' high, pileus 1—1.5° broad, stem 
2"-4" thick. 
Thin soil and decaying leaves covering rocks. Slope of Crows 
Nest near West Point. June. 
When young the whole plant is coated by an abundant super- 
ficial floccose-tomentum. ‘This soon breaks up into loose scales or 
patches which peel off in flakes, revealing the smooth pileus 
beneath. This character will readily distinguish this plant from 
C. atramentarius to which it is allied. The slight abrupt annulus 
soon vanishes. 
HyGRrorHorvus CHLOROPHANUS /7. 
Mossy ground. Greenbush. June. 
Ours is a small form, var. coccinea, with the disk of the pileus 
bright red. This color gradually fades into yellow on the margin 
where it is varied by the brighter colored striations. 
Marasmivus semiuirtires Pech. 
Pileus thin, tough, nearly plane or depressed, smooth, sometimes 
striate on the margin, hygrophanous, reddish-brown when meist,
