in. high. Dr. Cooke and Prof. Peck both give this asa species, though 
Fries considers it a variety of A. phalloides. It is readily distin- 
guished from white forms of A. vaginatus, or of A. volvatus by the pre- 
sence of the annulus. 
b. Volva definitely circumscissile, the margined base persistent, the 
upper part separating into thick warts upon the pileus, 
3. A. MuscaARIUS, Linn. Pileus convexo-expanded; the margin stri- 
ate; the flesh beneath the viscid cuticle yellowish. Stipe cobwebby 
within, soon hollow, ovate-bulbous at the base; the volva adnate, con- 
centrically scaly-margined; the annulus superior, lax. Lamelle reach- 
ing the stipe and decurrent instriz. Spores .008 X .006 mm. 
In woods, not abundant in our region. This species does not appear 
in Lea’s Catalogue, but I have met with it in all localities; it is very 
common in the Eastern States. Pileus 3-6 in. broad, stipe 4-8 in. high, 
The color of the European plant is commonly orange or scarlet, but in 
this country it is usually bright yellow, sometimes varying to whitish. 
The lamelle are white, sometimes with a yellowish tint. Itis always 
to be distinguished by the scaly-margined bulbous base of the stipe: 
This plant, as its name indicates, is called the “Fly Agaric,” because its | 
flesh has been used to poison flies, bugs, etc. Is sufficient quantities, 
it is a highly narcotic violent poison, producing delirium and death, 
It is habitually used by some of the Tartar tribes of Eastern Asia to 
produce intoxication : a curious account of this may be found in Gold- 
smith’s Letters of a “ Citizen of the World,” letter xxxii. This state- 
ment has recently been verified by George Kennan in a volume entitled 
“Tent-life in Siberia,” page 203. 
4, A. PANTHERINUS, DC.—Pileus convexo-expanded ; the margin 
striate ; the flesh beneath the viscid cuticle white. Stipe stuffed, then 
hollow, nearly glabrous ; the base ochreate by the volva, the margin of 
which is entire and obtuse. Lamelle attenuate, free. Spores .0076 x 
.0048 mm. 
In pastures along the borders of woods. Pileus 4-6 in. in diameter, 
stipe 5-7 in. long. Pileus white or brownish, never yellow or red, when 
dry, soft to the touch like kid leather; the annulus is usually midway 
of the stipe or distant from its apex, it is often found deflexed or with — 
its margin turned upward; the volva invests the base of the stipe 
smoothly, and has a separable or free margin, which is bluntly obtuse 
or truncate. ‘The species is reputed poisonous.
