The wide distribution and the economic importance of the Cercospora in this county has prompted the writing of this paper. This list by no means represents all of the species of this county, as no special effort has been made to collect Cercospora only. These collections were made while passing to and from other duties. With few exceptions, the species were collected in the immediate vicinity of Tuskegee.

The exceedingly warm and humid atmosphere, together with the very remarkable fluctuations of climate and rapid development of fungus diseases under these favorable conditions, has made the study doubly interesting. It is quite apparent that from year to year, by careful co-operation, much valuable information will be brought to light. None of our imperfect fungi have been worked over more carefully than the Cercosporeae. I have consulted the following works, Ellis and Everhart, whose work includes all of the North American species known to them when their work was written. Kellerman and Swingle for the descriptions of several new species. There are also descriptions of other species in the same journal.
