Cercospom copalUna, Cke., Grev. XII, p. 31, Rav. Fungi Amer. 586, 

 is said to be "quite different," bat it is not stated in what the difference 

 consists. As far as v^e can see, the specimen in F. Am. 586 does not 

 differ in any way from the A. F. specimens. There are the same 

 olive brown tufted liyphse in both. The spots and conidia also appear to 

 be the same.
