Murrill: Amanitas of Eastern North America 77 
11. Venenarius russuloides (Peck) 
Agaricus (Amanita) russuloides Peck, Bull. Buf¥alo Soc. Nat. 
Sci. 1:41. 1873. 
Described from Greenbush, New York, and found in grassy 
ground in open woods or groves in New York and Massachusetts. 
According to Beardslee, it is not distinct from Amanita junquillea 
Quel., which, according to Boudier, is the same as A. vernalis Gill, 
and A. Amici Gill. The descriptions of V. russuloides and A. 
junquillea appear to be identical, except for the “ tuberculate 
margin” of the former. Boudier’s figures come nearer to repre- 
senting our plant than do those of Quelet. 
12. Venenarius crenulatus (Peck) 
Amanita crenulata Peck, Bull. Torrey Club 27: 15. 1900. 
Described from eastern Massachusetts, and known to occur in 
low shaded places in that part of the state. It resembles V. rus- 
suloides and V. cothurnatus in many ways, but the surface has a 
peculiar flocculent or webby covering similar to that of V. mus- 
cariiis, and the base of the, stipe is not ocreate.
