Murrill: Poisonous Mushrooms

from all accounts, while L. torminosa, L. fuliginosa, L. vellerea, 

 L. pyrogala, and L. theiogala are either pronounced poisonous or 

 suspicious by most authors. Care should be exercised in collect- 

 ing members of this genus for the table. 



Lepiota Morgani Peck 



This species, which occurs rather abundantly from Indiana to 

 Kansas and south to Texas, may be readily distinguished from 

 Lepiota americana and other species of the genus by its green 

 spores. It is harmless to some persons but poisonous to others, 

 though never fatal. Old specimens appear to contain more poi-

Marasmius peronatus Fries 



Considered slightly poisonous to some persons. It occurs in 

 woods and is sufficiently distinct from M. oreades to avoid con- 

 fusing the two. It is probably only a form of M. urens. 

 Marasmius urens Fries 



This species, long considered slightly poisonous, grows in pas- 

 tures and should be carefully distinguished from M. oreades. 



Panaeolus campanulatus Fries 

 A century ago this species was reported poisonous, inducing 

 sleep. Macllvaine has tried it in small quantities without harm- 

 ful results. 



Panaeolus papilionaceus Fries 

 Said to produce hilarity and a mild form of intoxication if 

 eaten in quantity. 



Panus stypticus Fries 

 Extremely astringent and disagreeable, and considered poison-

 account of its small size and apparently tough consistency, few 

 persons would think of eating it. 



RUSSULA 



It seems to be pretty well established for the American species 

 of this genus that have been investigated that all having an agree-
