HYMENOMYCETES.

Pileus at first ovate, then expanded or convex, rough with a few superficial 
warts or entirely smooth, viscid when moist, widely striate-tuberculate on the 
margin, pale yellow or straw color; lamellae close, free, narrowed toward the 
stem, white ; stem firm, smooth, stuffed, annulate, equal or slightly tapering 
upward, bulbous ; annulus thin, soon vanishing; volva fragile, subappressed ; 
spores broadly elliptical, .0004’* long, .0003’ broad. 
Plant 2’-3’ high, pileus 1.52’ broad, stem 3”}-5” thick. 
Grassy ground in open woods. Greenbush, June. This species 
is remarkable for the thin striate-tuberculate margin of the pileus 
which causes it to resemble some species of Russula. 
Agaricus (Lepiota) fuscosquameus, Peck. 
Pileus hemispherical or convex, rough with numerous erect pointed black- 
ish-brown scales; lamellae close, white, free; stem equal, thickened at the 
base, hollow or stuffed with a cottony pith, floccose, brown ; spores .0003' x 
00014’. 
Plant 2’-3' high, pileus 1.5’-2’ broad, stem 3” thick. 
Ground in woods. Croghan. September. 
Agaricus (Lepiota) oblitus, Peck. 
Pileus convex or expanded, subumbonate, smooth or obscurely squamose 
from the breaking up of the veil, viscid, alutaceous inclining to tawny, the
