odor. From R. granulosa Cke. it may be separated by its 

 glabrous stem, smaller spores and adnate lamellae. R. granu- 

 lata lepiotoides Atk. is a variety having the surface of the 

 pileus rimose squamose. 



Russula foetens (Pers.) Fr. 



FETID RUSSULA 



Pileus fleshy, fragile, subglobose or convex becoming plane or 

 centrally depressed, viscid when moist, widely tuberculose sulcate 

 or striate on the very thin margin, yellowish or dingy ochraceous, 

 flesh pallid, taste acrid, odor strong, amygdaline; lamellae rather 

 close, adnexed, unequal, some of them forked, whitish and often 

 studded with drops of moisture when young, becoming yellowish 

 with age, dingy where bruised, interspaces venose ; stem short, stout, 

 stuffed becoming irregularly hollow, white or whitish ; spores white, 

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



Pileus 3-5 inches broad; stem 1.5-2.5 inches long, 6-12 lines 

 thick. 



Woods and bushy places. Common. July to September. 



Readily recognized by its peculiar odor, acrid taste and widely 

 striate margin. Gregarious in habit and somewhat variable in 

 color. 



Russula foetentula n. sp. 



SLIGHTLY FETID RUSSULA 



Pileus thin, nearly plane, viscid, glabrous, striate on the margin, 

 reddish yellow, flesh white, taste tardily acrid, odor like that of 

 almonds; lamellae thin, narrow, close, adnexed or nearly free, 

 whitish, the interspaces venose ; stem equal, firm, cavernous, white 

 or yellowish white, usually spotted or stained with reddish brown 

 at the base; spores very pale yellow, globose, .0003-.00035 of an 

 inch broad. 



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



Among fallen leaves in woods. Suffolk county. August. 



This species is related to R. f o e t e n s Fr., to which it is similar 

 in odor but from which it differs in its closer lamellae and reddish 

 brown or burnt sienna color at the base of the stem. 



The specimens reported in State Museum Report 35, page 135 

 under the name Russula heterophylla Fr. are doubtful 

 and the species is therefore omitted.
