Frost's Amanita. Poisonous.

Frostiana, named in honor of Charles C. Frost.

The pileus is convex, expanded, bright orange or yellow, warty, sometimes smooth, striate on the margin, pileus one to three inches broad.

The gills are free, white, or slightly tinged with yellow.

The stem is white or yellow, stuffed, bearing a slight, sometimes evanescent, ring, bulbous, at the base, the bulb slightly margined by the volva. The spores globose, 8–10µ in diameter. Peck.

Great care should be taken to distinguish this species from A. cæsarea because of its often yellow stem and gills. I found some beautiful specimens on Cemetery Hill and on Ralston's Run. It is very poisonous and should be carefully avoided, or rather, it should be thoroughly known that it may be avoided. The striations on the margin of its yellow tinge might lead one to mistake it for the Orange Amanita. It is found in shady woods and sometimes in open places where there is underbrush. June to October.
