and distant margin; the portion covering the pileus divided into broad, Amanita, 

 irregular, somewhat separating scales. Gills annexed, crowded, nar- 

 row, shining, white. Fries. 



Odor stinking. The color is that of A. phalloides, with which A. 

 virosa exactly agrees, more rarely straw color, lemon-yellow, becoming 

 green. 



In mixed woods. Frequent. Stevenson.

POISONOUS. 



Probably but a variety of A. phalloides. 



A. spre'ta Pk.sfreta, hated. (Plate VI, fig. i, p. 6.) Pileus 



subovate, then convex or expanded, smooth or adorned with a few 

 fragments of the volva, substriate on the margin, whitish or pale-brown. 

 Gills close, reaching the stem, white. Stem equal, smooth, annulate, 

 stuffed or hollow, whitish, finely striate at the top from the decurrent 

 lines of the lamellae, not bulbous at the base, but the volva rather large, 

 loose, subochreate. Spores elliptical, generally with a single large 

 nucleus, io-i3x6-8/u-. 



Plant 4-6 in. high. Pileus 3-5 in. broad. Stem 4-6 lines thick.

This is a dangerous species, because containing a deadly poison and 

 resembling the most common forms of Amanitopsis, therefore likely to 

 be mistaken for them. Specimens sent by me to Professor Peck were 

 identified as his species. I add my own description. 



Pileus oval, broadly umbonate, date-brown toward and on umbo, 

 soft, dry, smooth, more or less sulcate on edge. Flesh white, thin, 

 except at center. Stem tapers rapidly above ring and at base, white 

 reddish-brown toward middle, narrows toward volva from which it is 

 almost free at the base, hollow, furfuraceous above ring. Gills white, 

 crowded, free. Ring white, thin, persistent, but at times hard to dis- 

 tinguish because clinging to stem. Volva free, fitting close, upper
