to the base of the large, rounded bulb, the limb usually free, con- 
spicuous, lobed, thick and fleshy, persistent, but at times breaking 
partly or wholly into irregular patches that are either carried up 
on the surface of the pileus or remain at the base of the stipe. 
This most deadly species of all the fleshy fungi has been often 
described at length. The reader is referred to Mycologia for 
November, 1909, for a discussion of its poisonous properties. 
The variety of colors assumed by this species — white, yellow, 
green, gray, brown, blackish — and the fact that the annulus and 
the limb of the volva may sometimes be lost make it necessary 
to use great caution in selecting any white-gilled species with 
bulbous stipe for food, whether an annulus is present or not. All 
species of Venenariiis and Vaginata, and several species of 
Lepiota must be examined with great care.

Pileus hemispheric to plane, sometimes slightly depressed, very 
variable in size, 2-8 cm. broad ; surface dull-white or yellowish, 
rarely reddish-brown at the center or entirely reddish-brown, pul- 
verulent, floccose-squamose, or with large volval patches ; lamellae 
free, rounded behind, broad, crowded, white; spores ellipsoid, 
smooth, hyaline, 10-12 X 6-7 /.i ; stipe very variable in size, 1-7 
cm. long, 3-8 mm. thick, equal or tapering upward, enlarged at 
the base, whitish, minutely floccose-squamose, stuffed or solid ; 
volva unusually large, firm, membranous, persistent, more or less 
lobed.
