aps are quite smooth and are frequently concentrically cracked or
wrinkled, much as in Clitopilus noveboracensis.

It is found growing on leaves in mixed woods, after a rain, in August
and September. When young the margin is incurved but wavy in age. It is
quite a hardy plant.

_Clitocybe adirondackensis. Pk._

[Illustration: Figure 71.--Clitocybe adirondackensis. Three-fourths
natural size. Caps white.]

Adirondackensis, so called because the plant was first found in the
Adirondack Mountains of New York.

The pileus is thin, submembranaceous, funnel-form, with the margin
decurved, nearly smooth, hygrophanous, white, the disk often darker.

The gills are white, very narrow, scarcely broader than the thickness of
the flesh of the pileus, crowded, long, decurrent, subarcuate, some of
them forked.

The stem is slender, subequal, not hollow, whitish, mycelio-thickened at
the base. _Peck._

The pileus is one to two inches broad and the stem is one to two and a
half long. This is quite a pretty mushroom and has the Clitocybe
appearance in a marked degree. The long, narrow, decurrent gills,
sometimes tinged with yellow, some of them forked, margin of the pileus
sometimes wavy, will assist in distinguishing it. I have no doubt of its
edibility. Found among leaves in woods after heavy rains. With us it is
confined to the wooded hillsides. The specimens in Figure 71 were found
in Michigan and photographed by Dr. Fischer. Found in July and August.

THE CLAY-PURPLE CLITOCYBE. EDIBLE.

Plate XI. Figure 72.--Clitocybe ochropurpurea.]

Ochropurpurea is from _ochra_, ocher or clay color; _purpureus_, purple;
it is so called because the caps are clay-color and the gills are
purple. The caps are convex, fleshy, quite compact, clay-colored,
sometimes tinged with purple around the margin, cuticle easily
separating, margin involute, often at first tomentose, old forms often
repand or wavy.

The gills are purple, sometimes whitish in old specimens from the white
spores, broad behind, decurrent, distant.

The stem is paler than the cap, often tinted with purple, solid,
frequently long and swollen in the middle, fibrous. The spores white or
pale yellow.

The first time I found this species I never dreamed that it was a
Clitocybe. It was especially abundant on our wooded clay banks or
hillsides, near Chillicothe, during the wet weather in July and
