On the ground in woods. 



Solitary, or usually growing in troops ; closely resembling: 

 C. digtorta in many respects, but more constant in form, and 

 differing in the gills not becoming spotted with red. 



Pileus 11- in. broad, snbcamose, convex, expanded, umbo- 

 nate, snbviscose, of a livid ochre or dull green, when quite- 

 young livid-brown ; the margin subrufesent, but a portion 

 below the umbo soon grows pale, so that the pileus appears- 

 of four colours. The umbo is always dark, but sometimes 

 the rest of the pileus is pale rafescent or ochraceous, margin 

 occasionally striate ; fle^un'hite mottled with rufous. Gills- 

 closeTTree, not jveotaicose, rounded, edge rather uneven 

 and notched. Spornles white. Stem li— 2 in. high, f in. 

 thick below, somewhat twisted, smooth, slightly striate,. 

 downy at the bullx)us base, stnffied white within, the outer- ;
