In woods. Pileus 4-1 in. broad, stipe 1-14 in. high. A beautiful 
little Omphalia, growing on leaves, I have here referred to this species. 
Some of my specimens are a little brownish on the pileus, with the 
lamelleze rather pale. It may prove to be something different.

Upon turf or sod in swamps and pastures, also on rotten wood;
