Amanita caesarea Scop. 
Pileus 4 to 10 inches broad, smooth, varying from bright scarlet 
to orange or dingy yellow, distinctly striate on the margin; gills 
yellow, free; stipe firm, stuffed, usually yellow and flocculose, 
with a large, persistent annulus. Volva large thick loose, persis- 
tent, white. Spores elliptical, 10 to 12 by 5 to 6 me. 
This is easily the finest and most striking of the Amanitas. It 
is very abundant in Western North Carolina, but is rare farther to 
the north. It is highly esteemed in Europe as an edible species, 
but like all the Amanitas should only be used for food when it has 
been identified beyond all possibility of mistake. It should be 
remembered that several species of Amanita are highly dangerous. 
Amanita spreta Peck. 
Pileus 2-6 inches broad, usually gray, or brownish gray, but 
varying to white. Smooth or nearly so, striate on the margin; 
gills white, free; stipe cylindrical, not bulbous, stuffed or hollow. 
Volva loose, free, persistent. Spores 10-12 by 7-8 me, elliptical. 
This is very abundant and also very variable. The common 
form at Asheville is large and robust, with the margin nearly even, 
and the pileus brown or dark gray. Other forms are found which 
are slender and occasionally almost pure white. The more slen- 
der forms are much like A. cinerea Pres, which is the European 
form of this species. One interesting form occurs on our dry hilh
