This genus differs from the genus Agaricus from the fact that its gills are attached to the stem and its stem is destitute of a ring.

Plate XXXVII. Figure 262.—Hypholoma incertum.
Incertum, uncertain. Prof. Peck, who named this species, was uncertain whether it was not a form of H. candolleanum, to which it seemed to be very closely related; but as the gills of that plant are at first violaceous and of this one white at first, he concluded to risk the uncertainty on a new species.
The pileus is thin, ovate, broadly spreading, fragile, whitish, margin often wavy and often adorned with fragments of the woolly white veil, opaque when dry, transparent when moist.
The gills are thin, narrow, close, fastened to the stem at their inner extremity, white at first, then purplish-brown, edges often uneven.
