umbilicate

This plant will be recognized by its smoky or grayish color, umbilicate pileus, and viscid stem.

It is minutely velvety on the upper surface, reddish-brown or cinnamon in color; expanded or umbilicate to nearly funnel-shaped.

Umbilicate, with a minute abrupt depression in the center of the cap.

In some of the species of Omphalia the pileus is not umbilicate, but here the gills are plainly decurrent.

The pileus is fleshy, oval to bell-shaped, becoming plane, and sometimes umbilicate.
