-LEPIOTA SUBLILACEA. 
Pileus thin, convex, obtuse or umbonate, dry, floccose-squamu- 
lose, brownish tinged with lilac, flesh white; lamellae rather 
broad, free, subdistant, whitish ; stem short, solid, colored like the 
pileus, but paler at the top, the annulus slight, evanescent; spores 
elliptical, .o004 in. long, .0002 broad, commonly containing a sin- 
gle large shining nucleus. Pileus 6-12 lines broad; stem 6-12 
lines long, 1—2 lines thick. 
Bare ground in pastures. Kansas. September. Bartholomew. 
This plant appears to have some points of resemblance to 
L. lilacea, from which it may be separated by its solid stem and 
larger spores. 
TRICHOLOMA ACRE. 
Pileus fleshy, but rather thin, broadly convex, nearly plane or 
even slightly depressed in the center, often wavy on the margin, 
dry, innately fibrillose, whitish or pale gray, flesh white or whitish, 
taste acrid; lamellae close, adnexed, subventricose, white; stem 
equal or slightly tapering downward, short, slightly fibrillose, 
stuffed or hollow, white; spores subglobose, .0002—.00025 in. 
long, .00016-.0002 broad. Pileus 1.5-2.5 in. broad ; stem I—2 in. 
long, 3-5 lines thick.

The species is closely related to the European 7: cmpolitum, 
from which it appears to differ in its paler pileus not becoming 
rimose-squamose, and inits stem, which is not at all squamose and 
which is stuffed or hollow rather than solid. Besides, its taste is 
only hot or peppery and not at all salty as in that species. 
‘TRICHOLOMA PALLIDUM. 
Pileus fleshy on the disk, thin towards the margin, convex or 
nearly plane, obtuse, glabrous, sometimes obscurely spotted on 
the disk with thin appressed brownish squamules, someWhat shin- 
ing, whitish tinged with yellow or brownish-yellow, flesh white, 
sometimes slowly assuming a faint pinkish hue where cut or 
broken, taste mild ; lamelJae broad, subdistant, rounded behind or 
adnexed, often eroded on the edge, white; stem equal or slightly 
thickened at the base, glabrous, white ; spores elliptical, .0002— 
.00025 in. long, .00016 broad. Pileus 1-2.5 in. broad; stem 1-2 
in. long, 3-6 lines thick.
