STUDIES OF AMERICAN FUNGI. 



KicrKK 



has led Hennings to place the plant in Karsten's genus (Engler and 

 PrantI, Pflanzenfamilien) Chalymotta, as Chalymotta retirugis. The 

 plants have several times been eaten raw by me, and while they 

 have a nutty flavor and odor, the taste is not entirely agreeable in 

 this condition, because of the accompanying slimy sensation. 



A number of smaller species, among them P. fimicola Fr., and P. 

 papilionaceus Fr., occur in similar places. Panaeolus solidipes Pk., is a 

 large spt-cies with a long, solid stem, growing on dung. Psilocybe 

 foenisecii, abundant in lawns and grassy places during late spring and 

 summer, resembles a Pan:i>olus. The cap shows zones of light and 

 dark color, due to different amounts of water, which disappear as 

 the plant matures, it belongs to the purple-brown-spored agarics. 



PSATHYRELLA Fr. 



The pileus is thin, membranaceous, striate, the margin not ex- 

 tending beyond the edge of the gills, and when young the margin 

 of the pileus lies straight against the stem. The gills are black to 



fuliginous, of a 

 uniform color, i.e., 

 not spotted as in 

 PaniTolus and An- 

 nellaria. The 

 spores are black. 

 The plants are all 

 fragile. Only one 

 species is men- 

 tioned here. In 

 appearance the 

 species are like 

 Psatliyra of the 

 pur p 1 e- b r own- 

 spored agarics, 

 but much thinner. 

 Peck describes 

 three species in 

 the 23d Report N. 

 Y. State Mus., p. 

 102 et seq. Only 

 one species is de- 

 scribed here.
