plants, in some of the other species it may sometimes appear but it 

 is exceptional. This character militates against the character of the 

 subgenus and connects with the next following one. Sometimes the 

 cuticle cracks on the margin very much as in R. cutefracta 

 but the paler and different colors of the pileus, the white flesh 

 beneath the cuticle and the striate margin easily prevent any con- 

 fusion of these species. The scales of the pileus often appear as if 

 formed from the breaking up of a crustose cuticle. This sometimes 

 has a grayish appearance. 



Russula modesta n. sp. 



MODEST RUSSULA 



Pileus firm but thin and flexible, broadly convex, becoming nearly 

 plane or centrally depressed, dry, pruinose, even or obscurely striate 

 on the margin, greenish gray, paler on the margin, flesh white, taste 

 mild ; lamellae thin, close, many forked at the base, a few short ones, 

 narrowed toward each end, adnate or slightly decurrent, white be- 

 coming yellowish, the interspaces venose ; stem short, cylindric, solid, 

 glabrous, white ; spores subglobose, pale yellowish, .00025-.0003 of 

 an inch long, nearly as broad. 



Pileus 1-2.5 inches broad; stem 1-1.5 inches long, 3-5 lines thick.

This species differs from its allies in the pruinose appearance of 

 the surface of the pileus. Under a lens, this is seen to be due to a 

 minute whitish tomentose pubescence. A form of this species with 

 the pileus more distinctly green has been received from Miss T. L. 

 Smith who collected it under oak trees and reports it to be edible.

YELLOWISH RUSSULA 

 State Mils. Bui. 105. 1906. p. 38, pi. 97, fig. 1-6. 



Pileus firm, convex becoming nearly plane or centrally depressed, 

 dry, frequently sprinkled with minute mealy yellowish particles, 

 specially on the margin, pale yellow, sometimes brighter yellow or 

 orange in the center, flesh white, taste mild ; lamellae rather thick, 

 moderately close, entire or nearly so, adnate, white ; stem equal or 

 slightly tapering upward, solid, sometimes becoming spongy within, 

 occasionally cavernous, colored like the pileus or a little paler, some- 

 times brighter at the base ; spores yellowish, subglobose, .0003 of an 

 inch long, nearly as broad.
