SOME COMMON MUSHROOMS AND HOW TO KNOW THEM 9 
Great care must be exercised to distinguish species of Amanitopsis 
from those of Amanita from which the ring has disappeared. 
AMANITOPSIS VAGINATA. SHEATHED AMANITOPSIS 
(eS 70) 
In this species the cap is thin and fragile, ovate to bell-shaped, sometimes 
umbonate, gray, mouse colored, or brown, smooth, shining, margin striate; 
the gills are white, broad, free; the stem is slender, fragile, smooth, or mealy, 
not bulbous; the volva is sheathing, white, easily separable from the stem, 
often remaining in the ground. 
FIGURE 6.—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
