It is undoubtedly _poisonous_ to a high degree. Its juices in minute quantity, carefully and scientifically injected into the circulation of etherized cats, kill in less than a minute. A raw piece of the cap, the size of a hazel nut, affects me sensibly if taken on an empty stomach. Dizziness, nausea, exaggeration of vision and pallor result from it. The pulse quickens and is full, and a dreaded pressure affects the breathing. I have not noticed change in the pupil of the eye. Nicotine from smoking a pipe with me abates the symptoms, which entirely disappear in two hours, leaving as reminiscence a torturing, dull, skull-pervading headache. If, as is asserted on good authority, the Siberians use it as an intoxicant, they certainly suffer the accustomed penalty. It is possible that persons may, in a degree, become immune to its poison, as they do to arsenic, strychnia, opium, nicotine, or it may be that a portion of the poison is extracted by boiling. It is, however, extremely dangerous to rely upon extracting by any means the poison of the Amanita, and to eat the residue. Acetic acid or vinegar does _not_ destroy the poison; it dissolves it to an extent and extracts it, and becomes as poisonous as the plant itself. There is no means of telling how much of the poison remains in the plant after such treatment. The safe plan is to eat, only, of toadstools which do not contain any poison to extract. One redeeming virtue, alone, rests with A. muscaria—it kills flies. =A. Frost´iana= Pk.—in honor of Charles C. Frost. POISONOUS. (Plate VI, fig. 5, p. 6.) =Pileus= convex or expanded, bright-orange or yellow, warty, sometimes nearly or quite smooth, striate on the margin. =Gills= free, white or slightly tinged with yellow. =Stem= white or yellow, stuffed, bearing a slight, sometimes evanescent ring, bulbous at the base, the bulb _slightly margined_ by the volva. =Spores= _globose_, 8–10µ in diameter. =Plant= 2–3 in. high. =Pileus= 1–2 in. broad. =Stem= about 2 lines thick. June to October. This appears like a very small form of the Fly Agaric, to which, as var. minor, it was formerly referred. The only decided characters for distinguishing it are its small size and globose spores. Our plant sometimes grows in company with A. muscaria, but it seems to prefer more dense woods, especially mixed or hemlock woods. It is generally very regular and beautiful and has the stem quite often of a yellow color, and the bulb margined above with a collar-like ring. _Peck_, 33d Rep. N.Y. State Bot.
