138 FUNGUS-FLOKA. 



Among grass, under trees, &o. 



Clearly distinguished from C. dryophila by the broader, 

 thicker, less crowded gills ; and from" C. xanthopoda by the 

 absence of an umbo. 



CoUybia nummularia. Bull. 



Pileus about 1| in. across, dry, flesh thin; soon almost 

 plane and slightly depressed round the umbo, even, pallid 

 ■or whitish, often variegated with reddish or yellow stains ; 

 gills free, broadest behind, rather distant, white; stem 

 1^-2 in. long, 1 line or more thick, often slightly thinner 

 downwards, pallid, stuffed then hollow. 



Agaricus nummularius, BuUiard, Champ., t. 66 ; Cke., Illustr., 

 pi. 151b; Cke., Hdbk., p. 69. 



Among leaves. 



Distinguished by being entirely white or pallid, and by 

 the plane pileus being slightly depressed round the small, 

 obtuse umbo. 



CoUybia esculenta. Wulf. 



Pileus |-| in. across, flesh thin, tough, white, pleasant 

 tasted ; convex then plane, orbicular, obtuse, glabrous, even, 

 or slightly striate when old, ochraceous-tan or brownish; 

 gills adnexed, often with a very minute decurrent tooth, 

 then seceding from the stem, very broad, almost obovate, lax, 

 rather distant, whitish or with a tinge of tan-colour ; stem 

 1-2 in. long, scarcely 1 line- thick, tough, straight, in- 

 distinctly hollow, even, glabrous, rather shining, yellowish- 

 tan, ending in a long, perpendicular, usually glabrous, 

 rooting base. 



Agaricus esculentus, Wulf, in Jacq. Coll., xi. t. 14, f. 4; 

 Cke., Hdbk., p. 69 ; Cke., Illustr., pi. 152a. 



In woods, pastures, &c. 



Gregarious but never caespitose. C. tenacella is allied to 

 the present species, but differs in the rooting base of the 

 stem being fibrillose, and in the snow-white gills. 



The root is sometimes 6 in. long, and downy when 

 growing amongst leaves, either perpendicular or flexuous. 

 Much eaten in Austria, where, in the beginning of April 

 large baskets of it are brought to market under the name 

 of Nagelschwamme, which accords with Linneus's name
