42 Thirty-third Annuai "Report of the 



the " False Orange " or Ely Agaric, Agaricus muscarius. Agaricus 

 aurantius Bull, and Amanita aurantia, Pers., are given as synonyms. 



Agaricus spretus, Ph. Despised Agaric. Pileus subovate, then 

 convex or expanded, smooth or at first adorned with a few fragments 

 of the volva, slightly striate on the margin, whitish or pale-brown ; 

 lamellae close, reaching the stem, white; stem equal, smooth, slightly 

 pruinose above the white annulus, stuffed or hollow, whitish, finely 

 striate at the top, inserted at the base in the rather large persistent 

 membranous somewhat sheathing volva; spores elliptical, .0004 in. to 

 .0005 in. long, .00025 in. to .0003 in. broad, generally containing a 

 single large nucleus. 



Plant 4 in. to 6 in. high, pileus 3 in. to 5 in. broad, stem 4 lines 

 to 6 lines thick. August. 



This species occurs in bushy or open places and seems to prefer a 

 dry gravelly or sandy soil. It is not common. It sometimes grows in 

 clusters and then has the pileus more or less irregular. The stria- 

 tions of the margin of the pileus are rather short and not always 

 deep and distinct. The lamellae reach the stem and form little de- 

 current lines at its apex. The stem is without any bulb at its base, 

 which is more or less sheathed by the persistent volva much as in A. 

 vaginatus. In light sandy soil the stem penetrates the earth quite 

 deeply. The whole plant is sometimes white, but often the pileus and 

 stem are tinged with brown. It appears to be related in some respects 

 to A. 'porphyrins and A. recutitus, but it differs from both in its col- 

 oration and in other characters. 



Agaricus phalloides, Fr. Phallus-like Agaric. Pileus at first ovate 

 or subcampanulate, then expanded, slightly viscid when young and 

 moist, smooth or rarely adorned by a few fragments of the volva, even on 

 the margin, white, yellowish-brown or blackish-brown ; lamellae rather 

 broad, rounded behind, free, white; stem equal or slightly tapering 

 upward, stuffed!or hollow, smooth or slightly floccose, annulate, bulbous, 

 the ruptured volva either appressed loos^ or merely forming a narrow 

 margin to the bulb; spores globose, .0003 in to .00033 in. f broad. 



Plant 4 in. to 8 in. high, pileus 2 in. to 5 in broad, stem 3 to 

 6 lines thick. Summer and Autumn. 



This species is common and variable. It occurs everywhere in woods 

 and assumes such different colors that the inexperienced mycologist 

 is apt to mistake its different forms for distinct species. With us the 

 prevailing colors of the pileus are white, yellowish-Avhite, grayish-brown 

 and blackish-brown. It is remarkable that the form with a greenish 

 pileus, which seems to be common enough in Europe, does not occur 

 here. Fries also mentions aform having a white pileus with ablack disk. 

 A somewhat similar form occurs here, in which the pileus is grayish- 

 brown with a black disk. Some of the variously-colored forms were 

 formerly taken to be distinct species, in consequence of which several 

 synonyms have arisen, of which A. virescens, Fl. Dan., Amanita viridis, 

 Pers., and Amanita citrina, Pers., are examples. A. vermis, Bull., is a 

 variety having a white pileus, a rather thick annulus and an appressed 

 volva. It sometimes occurs early in the season; hence the specific 

 name. It also occurs late in the season and runs into the typical 

 form so that it is not easy to keep it distinct. The flesh and the 

 lamellae are white, the stem is white, pallid or brownish, and the 

 annulus is either white or brownish. The bulb is generally very broad
