 :ii first. STEM pale lilac-violaceous to whitish. Otherwise like

This is a pretty little plant, and is usually combined with I. geo- 

 phylla. It is usually found in gregarious groups of several indi- 

 viduals and not mixed with /. geophylla. This fact and its 

 constantly independent color, leads me to believe that it does 

 not arise from the same mycelium as I. geophylla. The general ap- 

 pearance during development and the character of the surface of 

 the cap, although not easily differentiated in words, seem sufficient- 

 ly different from the white species.
