STUDIES OF AMERICAN FUNGI. 



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

 Prantl, Pflanzenfamilien) Chalymotta, as Chalymotta retinigis. 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 species with a long, solid stem, growing on dung. Psilocybe 

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

 summer, resembles a Panasolus. 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 

 Pa n a- o his and 

 And! aria. The 

 spores are black. 

 The plants are all 

 fragile. Only one 

 species is men- 

 tioned here. In 

 appearance the 

 species are like 

 Psathyra of the 

 pur pie- b rown- 

 spored agarics, 

 but much thinner.
