tevensoni._

[Illustration: Figure 429.--Peziza Stevensoni.]

This plant is sessile or nearly so, growing on the ground in dense
clusters. The specimens in Figure 429 grew in Dr. Chas. Miesse's cellar,
in Chillicothe. They grow quite large at times; are ovate, externally
grayish-white, covered with a minute down or tomentum, internally
reddish-brown, the rim of the cup finely serrated, as will be seen in
the figure below. They are found from May to July.

_Peziza semitosta._

[Illustration: Figure 430.--Peziza semitosta.]

Semitosta, from its scorched appearance, or umber-like color.

The cup is one to one and a half inches across, hemispherical,
hirsute-velvety without, date-brown within; margin indexed.

The stem is ribbed or wrinkled. Sporidia are subfusiform, .00117 inch
long.

These plants are found on the ground in damp places. It was formerly
called Peziza semitosta or Sarcoscypha semitosta. The plants in Figure
430 were found in August or September on the north side of the Edinger
Hill, near Chillicothe, and were photographed by Dr. Kellerman. No doubt
edible, but the writer has not tried them. This is called Macropodia
semitosta.

_Peziza aurantia. Fr._

ORANGE-GROUND PEZIZA. EDIBLE.

Aurantia means orange color.

Subsessile, irregular, oblique, externally somewhat pruinose, whitish.
The sporidia are elliptic, rough.

Found on the ground in damp woods. The cups are often quite large and
very irregular. Found in August and September.

_Peziza repanda. Wahl._

[Illustration: Figure 431.--Peziza repanda.]

Repanda means bent backward. These plants are found in dark moist woods,
growing on old, wet logs, or in well wooded earth. The cups are
clustered or scattered, subsessile, contracted into a short, stout,
stem-like base. When very small they appear like a tiny white knot on
the surface of the log. This grows, so that soon a hollow sphere with an
opening at the top is produced. The plant now begins to expand and
flatten, producing an irregular, flattened disk with small upturned
edges. The margin often becomes split and wavy, sometimes drooping and
revolute; disk pale or dark brown, more or less wrinkled toward the
center; externally the cup is a scurvy-white. The asci are 8-spored,
quite large. The paraphyses are few, short, separate, clavate, and
brownish at the tips. The spores are elliptical, thin-walled, hyaline,
non-nucleate, 14x9u.

Found from May to October. Edible.
