REPORT OF THE BOTANIST. 43 
when dry ; lamelle ascending, rather broad, subdistant, brown, 
becoming blackish-brown, the edge whitish ; stem long, straight, 
fragile, hollow, smooth, white; spores blackish, elliptical, 
.0006—.00065' long, .0003—.00033' broad. 
Plant gregarious, 4-6’ high, pileus 1’ broad, stem 1” thick. 
Ground in an old door yard. Maryland. September. 
This is allied to A. gracilis Fr., but the edge of the lamelle 
is not rosy. When drying the moisture leaves the disk of the 
pileus first, the margin last. When dry the plant bears some 
resemblance to large forms of A. fener. Under a lens the text- 
ure of the surface of the pileus is seen to becomposed of matted 
fibrils. 
CORTINARIUS (PHLEGMACIUM) OPHIOPUS 2. sp. 
Pileus firm, convex or subcampanulate, then expanded, 
sometimes irregular, viscid, reddish-yellow, smooth, the paler 
margin sometimes roughened by adhering patches of the 
whitish veil ; lamellee close, often eroded on the edge, brown- 
ish-cinnamon ; stem stout, equal, solid, usually much bent or 
variously curved, at first shaggy-scaly from the subconcentri- 
cally arranged fragments of the copious veil, white or yellow- 
ish ; flesh white ; spores unequally elliptical, .00045—.0005' long, 
.00025—.0003' broad, usually containing a single nucleus. 
Plant 4’-6’ high, pileus 2-4 broad, stem 4’—6” thick. 
Among fallen leaves in woods. Maryland. September. 
The long crooked stem is a noticeable feature of the species.

Low grounds. Center. October. 
CoRTINARIUS (HYDROCYBE) REGULARIS 2. sp. 
Pileus convex or expanded, glabrous, hygrophanous, watery- 
brown when moist, reddish-ochraceous when dry, often slightly 
radiate-rugulose ; flesh whitish, becoming white when dry; 
lamelle close, slightly violaceous when young; stem long, 
nearly straight, stuffed, slightly tapering upward, silky-fibril- 
lose, white ; spores elliptical, .0004 long, .0003' broad. 
Plant gregarious, 3—5 high, pileus 1-2’ broad, stem 1’—2” thick. 
Ses ee marsh. Center. October. 
e plant has avery regular symmetrical appearance, whence 
the specific name.
