Solitary or subcaespitose. In grassy places in woods or <»n 

 debris. Ann Arbor, New Richmond, infrequent. 



The persistently white umbo, deep color of the uills. fragile 

 texture and the silvery shining-white pileus when dry, characterize 

 the species. The size varies in differenl collections, normally rather 

 small, hnt in favorable situations becoming larger than figured in 

 the plates. The stem tends t<» elongate and is very fragile. The 

 color is not retained <>n drying. The spine- are a little large in 

 some specimens i»nt do nol agree with the large size given by 

 Saceardo and Massee, each of whom musl have deall with ;i differ 

 eni species. The surface of the pileus lacks any kind of differ- 

 entiated cuticle. The trama of the .uills is parallel and the margin 

 of the cap is a1 firsi incurved.
