1 Marasmius polyphyllus Peck 



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 fx ; 

 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 1st. 



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. prasiosmus 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 . prasiosmus 

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

 the plant. It has been suggested that M. polyphyllus 

 may be known in Europe as TV1 . p r a siosmus.
