The writer has not had opportunity to eat A. Cæsarea. If such should occur he would go about it very cautiously. No suspicion attaches to it abroad, but evidence is accumulating in the hands of the writer (not yet convincing) that either locality may render it poisonous or that A. muscaria varies so much in appearance as to deceive even the expert into mistaking it for A. Cæsarea. It is possible that A. muscaria is, at times, in certain localities, harmless; but no such exception as this is noted in the entire fungoid realm. It is not so common that collectors should mourn its waste. It is better, far, to let it alone. ** _Volva splitting regularly all around; pileus bearing thick warts, etc._ =A. musca´ria= Linn.—_musca_, a fly. (Plate VI, fig. 4, p. 6. Plate IX.) POISONOUS. =Pileus= 4 in. and more broad, normally at first blood-red, soon orange and becoming pale, whitening when old, globose, then convex and at length flattened, covered with a _pellicle_ which is _at first thick_, and in wet weather _glutinous_, but which gradually disappears, and sprinkled with thick, angular, separating fragments of the volva; _margin_ when full-grown _slightly striate_. =Flesh= not compact, white, _yellow under the pellicle_. =Stem= as much as a span long, shining white, firm, torn into scales, at first stuffed with lax, spider-web fibrils, soon _hollow_; the _adnate base of the volva_ forms an ovate bulb, which is _marginate with concentric scales_. =Ring= very soft, torn, even, inserted at the apex of the stem, which is often dilated. =Gills= free, but reaching the stem, decurrent in the form of lines, crowded, broader in front, white, rarely becoming yellow. Var. _rega´lis_, twice as large. =Stem= stuffed, _solid when young_, as much as 1–2 in. thick, becoming light-yellow within; the volva terminates in 8–10 concentric squamoso-reflexed rows of scales. =Pileus= very glutinous, bay-brown or the color of cooked liver. =Gills= yellowish. Var. _formo´sa_, soft, fragile. =Pileus= at first _lemon-yellow_, with mealy, lax, yellowish, easily-separating warts, often naked. =Gills= often becoming yellow. A. formosa, with the warts rubbed off. Var. _umbri´na_, thinner and _more slender_. =Stem= hollow, often twisted, bulb narrowed. =Pileus= at first _umber_, then livid, with the exception of the disk, which is dingy-brown. =Gills= at length remote. _Stev._ [Illustration: Photographed by Dr. J.R.
