1. AGARICUS AFFINIS Related Agaric.

A. Small, with a subcarnose somewhat fleshy campanulate bell-shaped pileus cap of a dilute violet color, lamellae gills of a clay-cinnamon color, and a punctate-fibrillose dotted and fibrous subcylindrical stipe stem.

It inhabits woods here and there on the ground in autumn.

The stipe is 2 inches and more in length, solid, sometimes hollow, 1-2 lines approx. 2-4 mm thick, concolorous of the same color with the pileus, fibrillose on the surface, but more truly powdery.

The lamellae are ascending, obovate egg-shaped with the wider end at the top, 2 lines and more in width, attached to the stipe, at first whitish-violet, then gradually they become a dirty clay-cinnamon.

The pileus is 1 inch wide, fragile, subpellucid somewhat translucent, umbonate having a central bump, either smooth or fibrillose, then especially on the disc center of the cap it becomes pale.

In size, shape, and the color of the lamellae, it agrees exactly with the Agaricus argillaceus Clay-colored Agaric OBS. MYCOL. 1. P. 51.. In the tenderness, especially of the stipe, it differs sufficiently from the Agaricus violaceus Violet Agaric of Linnaeus and species related to it.

The first table, Figure 1, shows this species in its natural size; 'a' shows it dissected perpendicularly, by which the lamellae appear more distinctly.
