GENUS Amanita<br />

Those who eat mushrooms are again warned that to learn the<br />

common poisonous species and avoid them and to eat all others is<br />

risking serious illness or death! The edibility of all species is not<br />

known. The only safe procedure is to learn thoroughly a few of<br />

the common edible ones and to avoid all others. The purpose of including<br />

some of the more common poisonous kinds in this book<br />

is to show how these resemble, and how they can be distinguished<br />

from, the common edible kinds.<br />

The genus Amanita, named for Amanos, a mountain in Asia<br />

Minor, contains the more common deadly species of mushrooms.<br />

These may be identified by the following characteristics. Learn<br />

them well!<br />

1. White spores.<br />

2. Gills that are free from the stem; that is, they extend almost<br />

to the stem but do not touch it.<br />

3. A ring around the upper part of the stem. In newly expanded<br />

specimens this is always visible and usually prominent,<br />

but it often collapses, withers, and disappears in older specimens.<br />

The stem should be examined very closely for evidence of it.<br />

4. A cup, or volva, surrounding the base of the stem. In some<br />

species this is beneath the surface of the ground or buried in leaf<br />

litter or grass and thus will be missed unless one carefully digs up<br />

the entire stem. Moreover, this cup also withers and almost disappears<br />

with age.<br />

To make identification even more difficult, the volva, instead<br />

of being always a definite cup-like structure enclosing the base of<br />

the stem, is sometimes merely a series of partial and inconspicuous<br />

rings on the swollen base of the stem, permitting confusion with<br />

the genus Lepiota and even with young specimens of Agaricus.<br />

The prominent and movable ring on the stem of Lepiota procera<br />
