Ann. Rep't N. Y. State Mus., 51 : 286. 1898. 



Pileus fleshy, thin, convex or nearly plane, gregarious or cespitose, 

 2.5-5 cm broad ; surface smooth, whitish to pale reddish brown, disk 

 darker in dried plants ; context having the odor and taste of onions ; 

 lamellae adnexed or nearly free, very crowded, narrow, white, 

 becoming yellowish in dried plants ; spores minute, 5-6 by 3-4 fi ; 

 stipe equal, hollow, 4-7 cm long, 2-4 mm thick, reddish brown, 

 covered with a white tomentum which is more abundant toward the 

 base. 



Shaded damp ground. Minerva, Essex county. July ist. 



Peck says " the peculiar garliclike flavor of this mushroom re- 

 mains in the mouth a long time after tasting the flesh. This species 

 is closely related to M . p r a s i o s m u s Fr. from which it differs 

 in its larger size, more crowded lamellae and smaller spores." It is 

 interesting to note that Ricken's description of M . p r a s i o s m u s 

 (Die Blatter. Deutschl.) differs little from this except in the size cf 

 the plant. It has been suggested that M. polyphyllus 

 may be known in Europe asM.prasiosmus.
