REPORT OF THE STATE BOTANIST. 133 
The elliptical spores and viscid pileus are distinguishing char- 
acters in this species. The pileus is often stained by the spores 
and it then has a sordid or squalid appearance. When not so 
stained it is very white if dry, watery-white if moist. The 
margin is very thin. The lamelle are dingy, when young, and 
they become darker with age. The stem is wanting or merely 
rudimentary. The pileus is attached by white filaments. 
AGARICUS (CREPIDOTUS) TILIOPHILUS, 7. sp. 
Pileus rather thin, convex, minutely pulverulent or subglabrous, 
hygrophanous, watery-brown and striatulate on the margin 
when moist, dingy buff-color when dry; lamellw# rather broad, 
subdistant, rounded behind, adnexed, colored like the pileus, be- 
coming ferruginous-cinnamon; stem very short, often curved, 
solid, eccentric, whitish, pruinose, with a white pubescence at the 
base ; spores ovate or subelliptical, brownish-ferruginous, -0002’— 
-00025' long, -00016’—-00018’ broad. 
Pileus 6"—12" broad, stem 2"—4" long, 1” thick. 
Dead trunks and branches of basswood, Tilia Americana. East 
Berne. August. 
Sometimes the plants are so closely crowded that they appear 
cexespitose . 
AGARICUS (HYPHOLOMA) NITIDIPES, 7. sp. 
Pileus fleshy, firm, convex, glabrous or obscurely fibrillose, 
whitish or yellowish ; lamellz close, adnexed, wh'tish or subcin- 
ereous, becoming rosy-brown, generally white on the edge; stem 
equal or slightly thickened at the base, solid, silky, shining, 
whitish ; spores ovate, rosy-brown, -0002’—- 00025’ long, -00016’— 
-00018' broad. 
Plant 2—4' high, pileus 2’—3’ broad, stem 3’—4” thick. 
Damp, shaded ground. Albany. September. 
Externally this species resembles A. precox, from which its solid 
stem and smaller spores at once distinguish it. 
AGARICUS (PAN OLUS) EPIMYCES, 7. sp. 
Pileus fleshy, at first subglobose, then convex, white, silky- 
fibrillose, flesh soft, white or whitish ; lamelle rather broad, some- 
what close, rounded behind, adnexed, dingy-white, becoming 
brown or blackish, with a white edge; stem short, stout, tapering 
upwards, strongly striate and minutely mealy or pruinose, solid 
in the young plant, hollow in the mature plant, but with the 
cavity small, hairy or substrigose at the base; spores elliptical, 
black, -0003'—-00035’ long, -0002—-00025’ broad. 
Plant 1’—1-5' high, pileus 8’—12" broad, stem 3’—4’ thick. 
Parasitic on fungi. North Greenbush. November.
