This genus has brown spores, and no volva at the base of the stem. The veil remains as a fringe attached to the margin of the pileus, but is not always apparent in old specimens; no portion remains as a ring on the stem. The gills are attached or grown fast to the stem at their inner extremity. In this respect, and also in having the stem destitute of a collar, the genus differs from the genus Agaricus.

Genus Stropharia

There are about seven species of this genus in America. The spores are brown, there is no volva, the stem has a collar, and the lamellae are united with the stem. They have no special economic importance.

Genus Psathyra

Two American species are reported for this genus. The spores are dark brown, there is no volva, the veil is inconspicuous or wanting, and the lamellae attached to the stem or notched at the inner extremity. The margin of the cap in the young plant and mature plant is always straight.

Genus Psilocybe

Eleven American species are reported for this genus. The spores are dark brown. There is no volva, the veil is inconspicuous or wanting, and the lamellae are attached to the stem or notched at the inner extremity. In the young plant the cap curves in at the margin.

Genus Pilosace

This genus has but one American species recorded. The spores are dark brown. There is no volva, and the veil is inconspicuous or wanting. The lamellae are free from the stem.

Genus Deconica

But one American species is reported. This has dark brown spores, and the lamellae growing down on the stem. The veil is inconspicuous or wanting, and there is no volva.
