396 FUNGUS-FLORA. 



Distinguished amongst the Porphyrosporae by the presence 

 of a distinct ring in conjunction with adnate or adnexed 

 gills. 



The species usually grow on the ground or on dung. 



Stropharia corresponds with Pholiota and Armillaria. 



Agreeing with Psalliota in having a distinct ring on the 

 stem, but differing much in other respects, especially in 

 having the substance of the stem continuous with that of the 

 pileus, and in the structure, and more or less adnate attach- 

 ment of the gills to the stem. (Fries.)
