GENERA AND SPECIES OF MUSHROOMS 



Cap rather thin; smooth or adorned when young with a 

 few adherent fragments of the veil (warty); bell-shaped to 

 expanded; sometimes umbonate; deeply (striated) furrowed 

 at the margin; regular in form but fragile and easily broken; 

 exceedingly variable in color, ranging from reddish white to 

 reddish-brown or leaden-brown; 2 to 4 inches broad. 



Gills free from stem; white or whitish; fragile. 



Stem without a ring but sheathed at the base by the torn 

 remains of the rather long, thin, flabby volva (veil or wrapper) ; 

 smooth or adorned with minute scales; variable in color; 

 hollow or stuffed; portions of the conspicuous white volva 

 are sometimes carried up as patches on the cap. Murrill. 

 3 to 5 inches long, K to ^ inch thick. 



Spores white; globular; smooth; glassy (hyaline); 8-10 

 microns in diameter. 



The sheath or wrapper at the base of the stem adheres so 

 slightly to the stem that if the plant is carelessly pulled the 

 sheath is left in the ground. My own experience indicates 

 that it is a fairly good mushroom, but there are many others 

 that I like better. Peck. 



This attractive and very variable species is abundant in 

 woods throughout Europe and North America during summer 

 and autumn and possesses excellent edible qualities. It may 

 be distinguished from species of Amanita, some of which are 

 deadly poisonous, by the total absence of a ring on the stem, 

 although the conspicuous volva at the base suggests its close 

 relationship to that genus. The variations in color presented 

 by this species are often very bewildering to the beginner. 

 Murrill.
