and without striations ; lamellae thin, distant, decurrent, persistently 

 white; stem short, even, glabrous, white; spores subglobose, .0003- 

 .0004 of an inch long, .00024-.0003 broad. 



Pileus 2-4 inches broad ; stem 1-2 inches long, 4-6 lines thick. 



Woods. Saratoga county. Rare. 



The specimens referred to this species have the white color of 

 the lamellae more persistent than in any of the preceding species 

 and the lamellae are less crowded than in the short stem russula. 

 Nevertheless they have a pale yellowish hue in the dried state and 

 are scarcely as wide apart as the description of the species would 

 indicate, but the disagreement is so slight that it is not sufficient 

 cause for a separation of our plant. 



Furcatae Fr. 



Pileus compact, firm, even on the thin margin, the thin pellicle 

 closely adnate; lamellae unequal, some of them forked, commonly 

 narrowed toward each end. 



The thin but even margin wath acute edge and the forked lamellae 

 are the notable characters of this subgenus. The lamellae do not 

 show decided changes in color v^^ith age or in drying, as in most 

 species of the preceding subgenus. In some species the pellicle is 

 separable on the margin.
