COPRIXUS. 309 



caused by the pressure of the edge of the pileus, in an early 

 stage of growth, which has somewhat the appearance of a 

 volva. (Berk.) 



Tufted. Pileus brownish-white or silvery grey, darker at 

 the summit, remaining campanulate for a long time, above 

 2 in. from the base to the apex, obtusely and irregularly 

 plicate, unequal, at length becoming plane and revolute. 

 Lamellae free, silvery grey, changing to black, contiguous 

 to each other, ventricose, dissolving in age. Stipes hollow, 

 white, 3-8 in. long, cylindrical, about ^ in. thick. This 

 species is well marked by the large folds or plaits which 

 often extend from the base to the very apex of the pileus. 

 (Grev.)

Amongst grass near to trunks, buried wood, &c. A very 

 large and beautiful species, distinguished from Coprinus 

 atramentarius, its nearest ally, by the larger size of every part, 

 the costate or waved lower portion of the pileus, the 

 truncate, depressed disc, with distinct squamules, the 

 whitish colour of the pileus, and the imperfectly hollow or 

 stuffed stem.
