Agaricus congregatus. Bull.,' t. 94. 



On the ground, also in hothouses, &c. 



Eeadily distinguished by the densely caespitose mode of 

 growth, the small size, the vispid, ochraeeous, glabrous pileus 

 ■which remains elongato-cylindrical for some time, then 

 becomes campanulate, and finally expands and splits at the 

 margin. 



Densely caespitose, fragile, readily distinguished from 

 Coprinus digitalis by its much smaller size ; stem short, thin ; 

 pileus from cylindrical to campanulate, glabrous, ochraeeous, 

 giUs adfixed, linear, white, then black. (Pries.)
