RUSvSULA. 95 



R. sordida. Pk. 



Pileus, three to five inches broad, firm, convex, then de- 

 pressed in center, dry. sordid white. 



Gills, close, white, some few forked. 



Stem, thick, equal, solid, concolor, when wounded becom- 

 ing at first rusty, then bluish black. 



Common in open woods throughout the Valley. It has a disgusting 

 odor in drying. 



R. furcata. Pers. 



Pileus, greenish, entire, fleshy, compact, margin even, 

 convex, plane depressed, margin thin, at first inflexed, pellicle 

 separable in spots. 



Gills, adnate, decurrent, rather thick, attenuated at both 

 ends, frequently forked, shining white. 



Stem, solid, white, attenuated downwards. 



Taste bitter, considered poisonous. May easily be mistaken 

 for R. virescens (which are edible) owing to the green color ; 

 but the gills are decurrent and the pellicle of the pileus is even, 

 not arcolated like in R. virescens. 



In open woods. Frequent. July and August. 



R. depallens. Pers. 



Pileus, pale red, inclining to darker red, fleshy, firm, gen- 

 erally irregular shaped and undulated, even, the thin adnate 

 pellicle changing color, the spreading margin even, slightly 

 striated when older, flesh white. 



Gills, adnexed, forked at base, often with shorter ones 

 mixed, white. 



Stem, solid, attenuated downwards, white, becoming 

 cinereous when older. 



Connnon in woods. July and August.
