The whole plant in drying becomes of a dull pinkish-red 

 color. This plant was noticed in a previous report as A. 

 rachocles, but upon further investigation I am satisfied it is 

 a species distinct by its umbonate, not depressed pileus, 

 sub striate margin, fixed annulus, and peculiar elongated 

 bulbous base. 



* Species marked with the asterisk have been before reported, but are repeated for 

 the sake of the description, 

 t Having an abrupt obtuse elevation or boss in the center.
