but paler than the pileus ; spores bright ochraceous buff, globose, 

 .0004 of an inch broad. 



Pileus 2-4 inches broad; stem 1.5-2.5 inches long, 6-10 lines 

 thick. 



Ground under oak trees. Albany county. July. Rare. Edible'. 



There is a var. a 1 b i p e s Pk. in which the pileus is deeper red 

 and the stem white. If this mushroom is stewed in milk or cream 

 without peeling, it imparts a pinkish purple hue to the liquid.

Pileus nearly hemispheric becoming broadly convex, plane or cen- 

 trally depressed, dry, pruinose or minutely pulverulent, dark crim- 

 son or purplish, sometimes darker in the center than on the margin, 

 rarely striate on the margin when old, flesh white, pinkish under 

 the cuticle, taste mild or slightly and tardily acrid ; lamellae rather 

 close, adnate, white becoming yellowish with age ; stem equal, solid 

 or slightly spongy within, colored like or a little paler than the 

 pileus, usually white at each end, rarely entirely white ; spores pale 

 yellow, globose, .0003 of an inch broad. 



Pileus 1-3 inches broad; stem 1-2 inches long, 3-5 lines thick. 



In woods and in open places. Common. July and August. 

 Edible. 



This species is easily distinguished by its pruinose or minutely 

 granular cap. When moistened and rubbed on white paper it com- 

 municates reddish stains to it. A few of the lamellae are forked at 

 the base. The pileus sometimes fades with age, specially in purplish 

 specimens, and on the margin. Such specimens resemble Russula 

 d e p a 1 1 e n s (Pers.) Fr. as shown in Cooke's figure 102 1. 



Russula lactea (Pers.) Fr. is omitted; the specimens re- 

 ferred to it belong to R u s s u 1 a a 1 b e 1 1 a Pk. 



Heterophyllae Fr. 



Pileus fleshy, firm, with a thin viscid adnate pellicle and a thin, 

 usually striate margin ; lamellae unequal, some of them forked ; 

 stem stout, solid, spongy within. 



The viscid pileus and striate margin separate this tribe from the 

 preceding one; the firm pileus, adnate pellicle and unequal lamellae
