Crepidotus herens, Px. 
Sticky Agaric. 
Pileus thin, four to twelve lines broad, convex, sessile, cuneiform 
or dimidiate, glabrous, or slightly squamulose, hygrophanous, viscid 
and striatulate on the margin when moist, white or whitish when dry; 
Jamelle moderately close, narrow, tapering toward each end, sub- 
cinereous. then brownish; spores e/liptical, pale-ferruginous, .0003 in. 
long, .0002 broad.

The elliptical spores and viscid pileus are the distinguishing charac- 
ters of the species. I know of no other viscid Crepidotus. The pileus 
is watery white or gray when moist, and white when dry, unless stained 
by the spores. The margin is very thin and the pileus is attached to the 
matrix by white filaments. The species is rare, having been observed 
but once. 
Crepidotus haustellaris, /’. 
Kidney-shaped Agaric. 
Pileus thin, four to ten lines broad, lateral or‘eccentric, reniform 
or suborbicular, plane, moist, slightly tomentose when dry, alutaceous 
or pale-ochraceous; lamellae broad, subdistant, rounded behind, 
slightly adnexed or nearly free, pallid, then brownish-cinnamon; stem 
short, distinct, solid, bulbous thickened at the base, whitened with a 
slight tomentose villosity ; spores elliptical, .00035 to .0004 in. long, 
.0003 broad. ;

Our specimens differ from the European plant in being smaller and 
of a paler color. The pileus is also sometimes eccentric, though 
Fries describes it as “exactly lateral” in the European plant.. ‘The 
dimensions of the spores are taken from our specimens, no spore 
characters being given in any description of the species to which we 
have had access. Fries remarks that the species is “small, regular, 
not cxspitose, especially marked by the subconic stem and almost free 
lamellz.” 
Crepidotus tiliophilus, P/. 
Linden-loving Agaric. 
Pileus moderately thin, six to twelve lines broad, convex, minutely 
pulverulent, hygrophanous, watery-brown and _ striatulate on the 
margin when moist, dingy-buff when dry; lamelle rather broad, 
subdistant, rounded behind, adnexed, colored like the pileus, becom- 
ing ferruginous-cinnamon ; stem two to four lines long, about one 
line thick, solid, often curved, pruinose, with a white pubescence at
