4:4 TiiiKTY-THiKi) Annual Report of the 



or on the margin only. Sometimes the fading process goes on until 

 the pilens is nearly white. In one variety the pileus is of a uniform 

 citrine or lemon-yellow color, in another it is wholly white. This form 

 I suspect is the same as A. subremotus, B. & 0. The margin is nar- 

 rowly and usually but slightly striate. Sometimes, especially after 

 heavy rains, it is not uncommon to find specimens almost or entirely 

 destitute of warts and even of the fragments of the volva at the base 

 of the stem. The flesh under the cuticle is not always yellow. It may 

 be either white or orange according to the color exhibited by the pileus. 

 The lamellae are sometimes faintly tinged with a yellowish or creamy 

 hue. The stem also, which is usually white, may be occasionally tinged 

 with yellow. The remains of the volva often encircle it at the base in 

 a somewhat concentric manner. The varieties already mentioned may 

 be characterized thus: 



Var. formosus (Amanita formosa, G. & E.) Pileus soft, fragile, 

 citrine-yellow, warts loose, white or yellowish. Var. albus. Pileus 

 white, warts rather firm, subacute. Var. regalis, a large form with 

 a liver-colored pileus, and Var. umbrinus with a thin, brown or livid 

 pileus and dark-brown disk I have not seen. 



The species is renowned for its intoxicating and poisonous properties. 

 Cordier states that it is one of the most active poisons and has caused 

 numerous accidents by being mistaken for the Orange Agaric. A kind 

 of fly poison is sometimes manufactured from it. If a moist plant be 

 placed where flies have access to it they will sip the viscid substance 

 from the surface of the pileus and pay the penalty with their lives. I 

 have seen it surrounded by a circle of dead flies thus destroyed. 



Agaricus Frostianus, Ph. Frost's Agaric. Pileus convex or ex- 

 panded, bright-orange or yellow, warty, sometimes nearly or quite 

 smooth, striate on the margin ; lamellae free, white or slightly tinged 

 with yellow ; stem white or yellow, stuffed, bearing a slight, sometimes 

 evanescent, annulus, bulbous at the base, the bulb slightly margined 

 by the volva; spores globose .0003 in. to .0004 in. in diameter. 



Plant 2 in. to 3 in. high, pileus 1 in. to 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 de- 

 cided characters for distinguishing it are its small size and glo- 

 bose spores. Relying mainly on the latter I have hesitatingly 

 admitted it as a species. It should yet be compared with Amanita 

 puella, G-. & R., which Fries regards as a mere form of A. muscarius, 

 characterizing it with the words "smaller, without warts." It is also 

 near, A. gemmatus Fr.,but that is described as having a solid exannulate 

 stem. Mr. Frost's manuscript description says " not often warty," but 

 I have nearly always found it more or less warty. The specific name 

 "affinis" which was given to this species by Mr. Frost, has been more 

 than once used, in connection with other species, and it seems best to 

 substitute another for it. Our plant sometimes grows in company 

 with A. muscarius, 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. 



Agaricus rubesceus, Pers. Reddish Agaric. Pileus at first ova>te, 

 then broadly convex or nearly plane, warty, slightly viscid when young
