within, white ; spores elHptic, pale yellow, .00035 of an inch long, 

 .00025 of an inch broad. 



Pileus 2-3 inches broad; stem 8-12 lines long, 5-6 lines thick. 



Dry ground in woods and bushy places. Fulton and Essex coun- 

 ties. July and August. 



Closely related to the next following species and like it somewhat 

 related to the subgenus Fragiles in some of its characters. 



Russula olivascens Fr. 



PALE OLIVACEOUS RUSSULA 



Pileus convex or nearly plane, umbilicate, olivaceous or pale green, 

 becoming yellowish in the center, even on the margin, flesh white, 

 taste mild ; lamellae narrowed toward the stem, close, slightly ad- 

 nexed, nearly equal, rarely forked, white becoming yellowish; stem 

 firm becoming spongy within, even, white; spores subglobose, yel- 

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



Pileus 2-3 inches broad ; stem 1-2 inches long, 4-8 lines thick. 



Woods. Suffolk county. August. 



This species differs from the preceding in the greenish color of 

 the cap, the gills more equal and rarely forked, the absence of a 

 bitterish flavor and in the more globose yellowish spores. 



Russula furcata (Pers.) Fr. 

 FORKED RUSSULA 



Pileus convex becoming nearly plane, centrally depressed or in- 

 fundibuliform, glabrous, the thin pellicle separable on the thin, even, 

 acute margin, varying from pale yellowish green to dark brownish 

 green, sometimes slightly tinged with purple, flesh white, taste mild ; 

 lamellae thickish, subdistant, often forked, unequal, adnate or 

 slightly decurrent, white ; stem equal or nearly so, solid or spongy 

 within, white; spores white, subglobose, .0003.-.00035 of an inch 

 long, .00025-0003 of an inch broad. 



Pileus 2-4 inches broad; stem 1.5-3 inches long, 5-8 lines thick. 



Woods. Albany county. July. 



The European plant is said to have a mild taste becoming bitter- 

 ish, and no purplish tints are attributed to the piJeus. In our plant 

 the bifurcations of the lamellae occur mostly near the inner and 

 outer extremities. It is thus far limited to a single locality near 

 Albany.
