In woods. 



Care must be taken not to confound the present with 

 bleached forms of other species. Distinguished by every 

 part being persistentl}' snow-white from the youngest stage, 

 the very narrow, crowded gills, and the very small spores. 



Russula semicrema. Fr. 

 Mild. Pileus about 3 in. across, flesh thick equally so np 

 to the margin, persistently white, firm ; convex then ex- 

 panded and depressed, sometimes wavy, polished white, nn- 

 changeable; margin incurved, glabrous, even; gills rather 

 decurrent, thin, crowded, 11-2 lines broad, persistently 

 white ; stem 1-3 in. long, up to 1 in. and even more thick,

 Among leaves. 



Intermediate between H. adusta and B. delica, but readily 

 distinguished from both. Stem fleshy, solid, firm, 2-3 in. 

 long, white, but becoming greyish and at length blackish 

 inside when broken. Pileus compactly fleshy, convex then 

 plane, even, glabrous, dry; disc umbilicate, margin at first 

 involute, always even ; colour in every stage persistently 

 white, flesh also, and juiceless ; gills decurrent, crowded, 

 thin, persistently white. Smell none, taste mild. (Fries.) 



Difl'ers from JR. adusta and B. densifolia in the persistently 

 white pileus (flesh also) and gills ; and from it. delica in the 

 flesh of the stem becoming blackish. The outside of the 

 stem often becomes dark with age.
