relationship to this subgenus. From R. 1 a c t e a Fr. it differs in 

 its fragile texture, equal lamellae and the surface of the pileus not 

 cracking and forming areolae. 



Russula v€temosa Fr. 



LANGUISHING RUSSULA 



Pileus convex becoming plane or centrally depressed, covered 

 with a slightly viscid adnate pellicle, even on the margin, red or flesh- 

 colored, typically becoming whitish or yellowish in the center, flesh 

 white, taste acrid ; lamellae narrow, broader in front, close, adnate, 

 a few shorter ones intermingled, white becoming yellowish ; stem 

 equal, even, fragile, soft, spongy within becoming hollow, white ; 

 spores pale yellow, subglobose, .0003-.00035 of an inch long, nearly 

 as broad. 



Pileus 2-3 inches broad ; stem 2-3 inches long, 5-8 lines thick. 



Thin woods. Saratoga county. August. Rare. 



In our specimens the pileus is in some cases a little paler in the 

 center than on the margin, but none of them is centrally whitish or 

 yellowish as in the typical form. The red pileus with even margin, 

 the acrid taste and pale yellow spores are distinguishing characters 

 in this species. 



Russula integra (L.) Fr. 

 ENTIRE RUSSULA 



Pileus firm, becoming fragile, convex becoming plane or cen- 

 trally depressed, covered with a viscid separable pellicle, thin on the 

 margin which is at length coarsely tuberculose striate, variable in 

 color, flesh white, taste mild ; lamellae broad, nearly free, equal, dis- 

 tant, white becoming pale yellow, dusted by the spores ; stem at 

 first short, conic, becoming clavate, even, ventricose, sometimes 

 cylindric, spongy within, white ; spores pale yellow, subglobose, 

 .0003-.0004 of an inch long, nearly or quite as broad. 



Pileus 3-5 inches broad ; stem 1.5-2.5 inches long, 6-12 lines thick. 



Woods. Adirondack region. July and August. Rare. 



The specimens which we have referred to this species are dark 

 red and do not always have the margin distinctly tuberculose striate. 

 The stem is cylindric or sometimes thickened toward the base. 



Var. rubrotincta Pk. Stem tinged with red. Otherwise as 

 in the typical form.
