Marasmius nigripes. Schw.

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.
