Have seen only the pure white form in Michigan. This Bpecies 

 approaches .1. panthcrina, common in Europe. The latter has a 

 brown to fawn-colored pileus which is Long-striate and has whitish 

 warts; its annnlus is median, and there are usually several oblique 

 rings <»r the volva a little above the bulb. .M m rill's figure in My- 

 cologia, VoL 5, PI. s7. is not of ;i typical plant. .1. cothurnata has 

 the bulb abruptly terminated by a close-fitting roll; its <;i|i may 

 have a slighl tinge of umber or yellow on the disk. Quelel and 

 Battaile give the spores of .1. pantherina as oval-elongate, LO-12
