Saccardo in his Sylloge describes no less than fifteen edible species of Amanita as found in different parts of the world. Of those I have personally been able to identify but three which are common in this country, and which have been well tested. Specimens of these three species are illustrated in Plates XIV and [XIV½] of this pamphlet. They are each and all found in varying abundance in different parts of the United States.
Plate XIV.
Figs. 1 to 4. Ag. (Amanita) Cæsareus Scop. (Amanita Cæsarea). "Orange Amanita," "True Orange."
Edible.
Cap at first convex, afterwards well expanded; smooth, free from warts, striate on the margin; color orange-red or bright lemon-yellow, with red disk; gills lemon-yellow, rounded near the stem, and free from it; stem equal or slightly tapering upwards, stuffed with cottony fibrils, or hollow (color clear lemon-yellow), bearing a yellowish ring near the top and sheathed at the base with large, loose, membranous, white volva. Odor faint but agreeable. Spores white, elliptical.
The whole plant is symmetrical in form, brilliant in coloring, clean and attractive in appearance. The American plant seems to differ in some slight respects from the European as figured and described in European works. In Europe the pileus or cap is said to vary in color, being sometimes white, pale yellow, red or even copper color, although it is usually orange-yellow. My own observation of the American plant of this species agrees with that of Prof. Peck in that the cap is uniform in color, being at first bright reddish-orange or even brilliant red, fading with age to yellow, either wholly or only on the margin. No white specimens have been as yet recorded in this country. The red color disappears in the dried specimens. The striations of the margin are usually quite deep and long and almost as distant as in the edible species Amanitopsis vaginata. Some European writers have described the flesh or substance of the cap as yellowish. In our plant the flesh is white, but stained with yellow or red immediately under the cuticle. Amanita Cæsarea is the only one of the Amanitas which has yellow gills.
Berkeley, in his "Outlines of British Fungi," describes A. Cæsarea as it is found in some parts of Continental Europe, but states that up to the date of his writing it had not been found in Great Britain. It is not recorded in the more recent lists of British fungi by M. C. Cooke nor in that of Australian fungi by the same author. The species has a wide range in this country, and though not very common in the North, in some localities, as in the pine and oak woods of North Carolina, it is found in great abundance. Dufour states that it is much esteemed as an esculent in France, and though rare in the northern part of that country, it is common in the center and the south of France in autumn. It is well known in different portions of Continental Europe, and is frequently figured in contrast with its very poisonous congener, Amanita muscaria, or "False Orange," commonly known as the "Fly Amanita," or "Fly-Killer."
