. epiphyllus in its habitat, in the papillate form of its
pileus and the stem's being flocculose, then smooth; also in that the
gills are united in a reticulated manner. Common. July to October.

_Marasmius epiphyllus. Fr._

THE LEAF MARASMIUS. EDIBLE.

Epiphyllus means growing on leaves.

The pileus is white, membranaceous, nearly plane, at length umbilicate,
smooth, wrinkled, plicate.

The gills are firmly attached to the stem, white, connected by veins,
entire, distant, few.

The stem is rather horny, bay, minutely velvety, apex pale, inserted.
The spores are 3x2u. This plant is abundant everywhere, on fallen leaves
in woods during rainy weather. July to October.

_Marasmius delectans. Morgan._

[Illustration: Figure 114.--Marasmius delectans. Natural size. Caps
white. Gills broad and distant.]

Delectans means pleasing or delightful.

The pileus is subcoriaceous, convex, then expanded and depressed,
glabrous, rugulose, white, changing in drying to pale alutaceous.

The gills are moderately broad, unequal, rather distant, trabeculate
between, white, emarginate, adnexed; the spores are lance-oblong,
hyaline, 7-9x4u.

The stem, arising from an abundant white-floccose mycelium, is long,
slender, tapering slightly upward, smooth, brown and shining, white at
the apex.

It is found growing on old leaves in woods. The plants in the figure
were collected in the woods at Sugar Grove, Ohio, by R. A. Young, July
28, 1906, and photographed by Dr. Kellerman. Found from July to October.

_Marasmius nigripes. Schw._

[Illustration: Figure 115.--Marasmius nigripes. Natural size. Caps and
gills white, stems black.]

Nigripes means black foot, so called because the stems are black.

Tremmelloid. Pileus very thin, pure white, pruinose, rugulose-sulcate,
convex then expanded.

The gills are pure white, unequal, some of them forked, adnate, the
interstices venulose.

The stem is thickest at the apex, tapering downward, black,
white-pruinose, the base insititious. _Morgan_.

It is found on old leaves, sticks, and old acorns and hickory-nuts. When
dry, the stem loses its black color and the gills become flesh-color. It
is quite common in thin and open woods. The spores are hyaline and
stellate, 3-5-rayed. Found from July to October.

This is called Heliomyces nigripes by some authors.

_Pleurotus. Fr._

Pleurotus is from two Greek words meaning side and ear, alluding to its
manner of growth on a log.
