SOME COMMON" MUSHROOMS AND HOW TO KNOW THEM \) 



Great care must be exercised to distinguish species of Amanitopsis 

 from those of Amanita from which the ring has disappeared. 



AMANITOPSIS VAGINATA. SHEATHED AMANITOPSIS 



(Fig. 7) 



In this species the cap is thin and fragile, ovate to bell-shaped, sometimes 

 umbonate, gray, mouse colored, or brown, smooth, shining, margin striate ;

Figuke G. — Amanita strobiliformis 



This is a very common and widely distributed species both in America and 

 in Europe and is subject to great variation in size, color, and habitat. It 

 may be found in woods, shaded situations, lawns, and sometimes on decaying 

 wood. 



LEPIOTA 



The genus Lepiota may be distinguished from Amanita and 

 Amanitopsis by the presence of a ring and the absence of a volva. 

 The cap is generally scaly or granular, and the stem is fleshy and
