character seems to be fairly constant. In P. graminis, however, 
there is some variation and it would seem as though the species 
described under that name would also include the variety " tupi" 
of Spegazzini. The divergence in this case from the typical P. 
graminis is sufficient, I think, to warrant the maintainance of the 
species name Andropogonis.

This fungus agrees in all features with the description given by 
Saccardo. In the specimens at hand, very little coloration occurs 
in the spores. Comparisons with exsiccati (Roum. Fungi Gall. 
4o6y), however, show that the form is without doubt Auers- 
waldia.
