Brief Description: [See More | Edit]

The pileus is thin, two to two and a half inches broad, broadly ovate, becoming convex, or nearly plane, somewhat striate on the margin, adorned with a few thin whitish floccose warts or with whitish flocculent patches, whitish or grayish, sometimes tinged with yellow.

The gills are close, reaching the stem, and sometimes forming decurrent lines upon it, floccose crenulate on the edge, the short ones truncate at the inner extremity, white.

The stem is equal, bulbous, floccose mealy above, stuffed or hollow, white, the annulus slight, evanescent. Spores broadly elliptic or subglobose, 7.5–10 long, nearly as broad, usually containing a single large nucleus. Peck, Bull. Tor. Bot. Club.

The stem is bulbous at the base but the volva is rarely seen upon it although slight patches are frequently seen on the pileus. The ring is very evanescent and soon disappears.
