Leucosporse 



whitish or yellowish warts, rarely smooth, narrowly and slightly striate Amanita. 

 on the margin, white, yellow or orange-red. Gills white. Stem equal 

 or slightly tapering upward, stuffed with webby fibrils or hollow, bear- 

 ing a white ring above, ovate-bulbous at the base, white or yellowish; 

 the volva usually breaking up into scales and adhering to the upper part 

 of the bulb and the base of the stem. Spores elliptical, 8-iox6-8/A. 



Plant 5-8 in. high. PileuS 3-6 in. broad. Peck, 33d Rep. N. Y. 

 State Bot. 



A white variety, with the pileus thickly studded with sharp warts, 

 occurs in Albany Rural Cemetery. July. Peck, 24th Rep. 



Var. atba Pk. It also occurs on Long Island in two forms, the 

 normal one and a smaller one, in which the warts of the pileus are 

 evanescent or wanting. Not unfrequently it makes a close approach to 

 white forms of A. pantherina, in having the upper part of the bulb uni- 

 formly margined by the remains of the definitely circumscissile volva, 

 but this margin is more acute than in that species. Peck, 46th Rep.

Spores spheroid-ellipsoid, 10-12x8-9^ K.; 6x9/^1 W. G. S.; ellip- 

 tical, 8-10x6-8/1 Peck. 



"At Cincinnati, yellow A. muscaria are all we find." Lloyd. 



Reported from most of the states. At Mt. Gretna I found it in great 

 quantity, and frequently three or four tightly crowded together. Many 

 pounds of it were sent to Professor Chittenden, Sheffield Laboratory, 

 Yale University. Near Haddonfield, N. J., large patches annually 

 grow under pines, gorgeous in their rich orange-red caps, usually scaly, 

 with at times lemon-yellow in the same clusters, smooth as A. Caesarea. 

 It grows from July until after hard frosts. 



It is undoubtedly poisonous to a high degree. Its juices in minute 

 quantity, carefully and scientifically injected into the circulation of ether- 

 ized cats, kill in less than a minute. A raw piece of the cap, the size 

 of a hazel nut, affects me sensibly if taken on an empty stomach. Diz- 

 ziness, nausea, exaggeration of vision and pallor result from it. The 

 pulse quickens and is full, and a dreaded pressure affects the breathing. 

 I have not noticed change in the pupil of the eye. Nicotine from 

 smoking a pipe with me abates the symptoms, which entirely dis- 

 appear in two hours, leaving as reminiscence a torturing, dull, skull- 

 pervading headache. If, as is asserted on good authority, the Siberians 

 use it as an intoxicant, they certainly suffer the accustomed penalty.
