picion by some. I collected the plant also
at Blowing Rock, N. C., in September, 1899. The caps of these specimens
measure 4 cm. in diameter.

=Agaricus diminutivus= Pk., is a closely related species. It is
distinguished chiefly by its somewhat larger size, and purplish to
reddish brown hairs on the surface of the pileus, and by the somewhat
larger spores, which, however, are small. I have found it at Ithaca, the
surface of the pileus hairy, with beautiful, triangular, soft,
appressed, purplish scales.

HYPHOLOMA Fr.

In the genus _Hypholoma_ the spores are purple brown, the gills attached
to the stem, and the veil when ruptured clings to the margin of the cap
instead of to the stem, so that a ring is not formed, or only rarely in
some specimens. The stem is said to be continuous with the substance of
the cap, that is, it is not easily separated from it. The genus is
closely related to _Agaricus (Psalliota)_ and _Stropharia_, from both of
which it differs in the veil not forming a ring, but clinging to the
margin of the cap. It further differs from _Agaricus_ in the stem being
continuous with the substance of the cap, while _Stropharia_ seems to
differ in this respect in different species. The plants grow both on the
ground and on wood. There are several species which are edible and are
very common. Peck gives a synopsis of six species in the 49th Report New
York State Mus., page 61, 1896, and Morgan describes 7 species in Jour.
Cinn. Soc. Nat. Hist. =6=: 113--115.

=Hypholoma sublateritium= Schaeff. =Edible=, _bitter sometimes_. The
name of this species is derived from the color of the cap, which is
nearly a brick red color, sometimes tawny. The margin is lighter in
color. The plants grow usually in large clusters on old stumps or
frequently appearing on the ground from buried portions of stumps or
from roots. There are from six to ten, or twenty or more plants in a
single cluster. A single plant is from 8--12 cm. high, the cap is 5--8
cm. broad, and the stem 6--8 mm. in thickness.

The =pileus= is convex to expanded, smooth, or sometimes with loose
threads from the veil, especially when young, even, dry. The flesh is
firm, whitish, and in age becoming somewhat yellowish. The =gills= are
adnate, sometimes decurrent by a little tooth, rather crowded, narrow,
whitish, then dull yellow, and becoming dark from the spores, purplish
to olivaceous. The =stem= usually tapers downward, is firm, stuffed,
smooth, or with
