This plant has a wide distribution in this country. The specimens figured were collected by H. H. York near Sandusky, Ohio, and were photographed by Dr. Kellerman. I have found them at various points in Ohio.

Figure 108.—Marasmius rotula. Natural size. Caps white or pale-buff.

Rotula means a little wheel.

The pileus is one to three lines broad, hemispherical, umbilicate, and minutely umbonate, plaited, smooth, membranaceous, margin crenate, white, or pale buff, with a dark umbilicus.

The gills are broad, distant, few, equal, or occasionally with a few short ones, of the color of the pileus, attached to a free collar behind.
