apical germ-pore. Cystidia present or absent. Growing on wood, more rarely on 
the ground, often densely caespitose or fasciculate.” — Eea. 
The species grow on decaying wood, often forming dense caespitose masses 
at the bases of stumps, or on the ground. The veil of the young state does not 
leave any ring on the stem but may remain as a fringe on the edge of the pileus. 
The species are divided into two sections, one with the pileus compact and firm 
and the other with it thin and fragile.
