AMAXITOrSIS 



The cap and stem are read- 

 ily separable as in Amanita 

 and L e p i t a, but the entire ab- 

 sence of a ring at all stages dis- 

 tinguishes this genus from its rel- 

 atives. In our one species the 

 volva is large and sheathing. The 

 generic name indicates the rela- 

 tionship with Amanita. 



Amanitopsis vaginata

 cm. wide, gray, yellowish, mouse- 

 colored or brownish, thin, smooth,

 ed from the margin toward the 

 disk ; stem tall, 8-20 cm. by 



6-9 mm., white, mealy or smooth, stuffed or hollow, volva a soft close sheath which 

 collapses readily; gills free, white; spores globoid, S-lO/i. The name refers to 

 the sheathing volva.
