Pennsylvanica. The characters by which it is separated from EH. Penn- 
sylvanca are, according to the author of the species, “its slender culms 
and panicle, the very short cauline leaves, the longer and wider lower 
elume, the more obtuse upper one and the shorter obtuser flowering 
glumes.” The flowers have a peculiarly blunt appearance by which the 
plant may be easily recognized.

Our specimens do not agree rigidly with the description of the spe- 
cies to which we have refered them. The pileus is either obtuse or 
umbonate, even or radiately rugose-wrinkled, and is generally even 
and regular on the margin. The stem also is either equal or slightly 
thickened at the base, but these variations are not of specific impor- 
tance. The flesh of the stem is yellowish as in Lepiota amianthinus to 
which this species is closely related, both in color and structure, but 
from which it may be distinguished by its habitat, its larger size and 
its entire membranous persistent annulus. 
Lepiota arenicola, ». sp. 
Pileus at first broadly conical, then convex or nearly plane, obscurely 
punctate with minute granular squaifules, whitish or cinereous, sub- 
striate and crenulate on the margin; lamelle broad, subventricose, 
distant, free, white; stem slender, equal, stuffed, glabrous, whitish, 
the annulus imperfect, obsolete or quickly evanescent; spores oblong 
or subfusiform, acute at one end, .0005 to .0006 in. long, .0002 to 
.00024 broad. 
Pileus 3 to 6 lines broad; stem 8 to 12 lines long, about 5 lines thick. 
Sandy soil. Karner, Albany county. August. 
The spores indicate an affinity of this species with L. metulispora, 
of which it might be regared as a dwarf variety, but it differs in its 
smaller size, more expanded pileus, distant lamelle and glabrous 
stem. The mycelium binds the sand into a globose mass at the base 
of the stem.
