Cercospora althaeina Sacc. On Callirhoe triangulata. Prairie 
du Chien and Grant County. The relationship to the form on 
Althaea is questionable. The conspicuous black-purple raised 
border of the spots in this collection give it a quite different ap¬ 
pearance. I have labeled it var. praecincta.

florus. Pepin.

Lake.
