FUNGI— II 
Esther Young 
In the May number of Mycologia, there appeared a report by 
the writer of this article which was the first of a series on Porto 
Rican Parasitic Fungi. A second article, by Mr. Garman, was 
published in the November number of Mycologia. This is the 
third of the series and is a report on the genus Cercospora. The 
work was done according to the method used in work reported in 
the first paper, when acknowledgments were made for valuable 
assistance rendered. The specimens were all collected by Dr. F. 
L. Stevens during the years 1912 and 1913 and the material is in 
the herbarium of the University of Illinois.
