44 THIRTY-2HIRD ANNUAL REPORT OF THE 
or on the margin only. Sometimes the fading process goes on until 
the pileus 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. & C. 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 notalways yellow. It may 
be either white or orange according to the color exhibited by the pileus. 
The lamelle 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. & R.) Pilens 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. wmbrinus with a thin, brown or livid 
pileus and dark-brown disk I have not seen. 
The species isrenowned 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, Pk. Frost’s Agaric. Pileus convex or ex- 
panded, bright-orange or yellow, warty, sometimes nearly or quite 
smooth, striate on the margin; lamelle 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. to3 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 ovate, 
then broadly convex or nearly plane, warty, slightly viscid when young
