GENERA AND SPECIES OF MUSHROOMS 



The genus Marasmius 



The tough, leathery texture of the small, thin mushrooms 

 of this white- spored genus is their distinguishing feature. 

 They quickly wither or shrivel in dry weather but revive again 

 in wet weather or when put into water and regain their fresh 

 apper ranee. The fact that they do not decay is another 

 important feature by which they may be distinguished. 

 Many of the rarer species of marasmius when fresh possess 

 an odor of garlic. 



Mushrooms belonging to this genus resemble others of the 

 genera Collybia, Lentinus and Panus. The species of mar- 

 asmius, though, are usually smaller than those of the two 

 latter species. The central stem of marasmius also differs 

 from the often lateral stems of Panus and Lentinus.
