whether they grow down on the stem; and whether the stem is 
hollow, solid, or filled with web-like mycelium, and whether it is 
fleshy or has a tough and hard rind. The lamelle may be of 
different or of equal lengths, and their edges may be entire or 
toothed or thin or blunt. 
To know a genus of the gill-bearing fungi, one must know 
the cap, gills, stem, and habit of growth which characterise that 
genus. 
A very young plant of the genus Amanita is enveloped in a 
membranous wrapper. The relation of the young plant to the 
wrapper will readily be understood by cutting 
a young plant through its length. 
As the plant grows, the wrapper is ruptured, 
a part is left at the base

Wrapper. The cap is, as a 
wrapper 
rule, regular and 
broadly convex. It may be almost 
flat when mature. The stem has a 
conspicuous collar and the gills are 
free from the stem. 
There are twenty American species in the genus Amantta ; 
some of them are the most poisonous patches 
fungi known, while others are most
