Cercospora all haeinaSacc. 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.
