Exoascus communis Sadeb. “On fruit of wild plum” Madi¬ 
son. (A. B. Seymour, Econ. Fungi 31) and Racine. 
In the preliminary list of parasitic Fungi of Wisconsin Tre¬ 
lease recorded Exoascus pruni Fckl. “On the fruit of Prunus,” 
causing ‘ ‘ plum pockets ” or “ bladder plums. ’ ’ This may have 
been, in part at least, what is now known as Exoascus communis 
Sadeb. on native plums. Atkinson, however, referred to speci¬ 
mens on Prunus domestica from Wisconsin {Cornell University 
Ag’l Exp. Station bulletin 73: 329).

In specimens of what appears to be Phyllosticta decidua Ell. 
& Kell, on leaves of Agrimonia striata collected at Long Lake

another collection on the same host, same locality and same day 
the sporules (4-7x3/*) have a fuligineous coloration.
