Leucosporae 



unchangeable. Stem solid, obese, of the same color as the pileus. Russuia. 

 Gills adnate then decurrent, thin, crowded, unequal, white then dingy, 

 not reddening when touched. Fries. 



Spores subglobose, almost smooth, 8-9/x Massee. 



In pine and mixed woods. 



West Virginia, Pennsylvania, New Jersey, in pine woods and in mixed 

 woods. August to frost. Mcllvaine. 



R. adusta is solitary but often in small troops. It is easily recognized 

 by the brownish blotches upon its cap, and the crowding of its thin gills. 



The solid flesh must be well cooked. It is then of good flavor. 



E. bre'vipes Pk. brews, short; pes, a foot. Pileus 3-5 in. 



broad, at first convex and umbilicate, 

 then infundibuliform, dry, glabrous 

 or slightly villose on the margin, 

 white, sometimes varied with red- 

 dish-brown stains. Flesh whitish, 

 taste mild, slowly becoming slightly 

 acrid. Lamellae thin, close, adnate 

 or slightly rounded behind; white. 

 Stem solid, white. 



Spores globose, verruculose, 10- 



(Plate XLV.)

RUSSULA BREVIPES. 



After Prof. Peck. 



Stem 6-10 lines long, 6-10 lines 

 thick. 



Sandy soil in pine woods. Quogue. September. 



This species is related to Russuia delica, but is easily distinguished 

 by its short stem and crowded gills. The pileus also is not shining and 

 the taste is tardily somewhat acrid. From Lactarius exsuccus it is 

 separated by the character of the gills and the very short stem which is 

 about as broad as it is long. The spores also are larger than in that 

 species. The gills in the young plant are sometimes studded with 

 drops of water. They are not clearly decurrent. Some of them are 

 forked at the base. The pileus is but slightly raised above the surface 

 of the ground and is generally soiled by adhering dirt and often marked 

 by rusty or brownish stains. The plants grew in old roads in the woods 

 where the soil had been trodden and compacted. Peck, 43d Rep. N. Y.
