Davis — Parasitic Fungi in Wisconsin — III. 259 



(Schw.) and Septogloeum uhneum. Both the American and 

 European specimens that I have seen have shorter sporules 

 (often 30 — 40/*) than the description indicates and are variable. 



Gloeosporium septorioides Sacc. On Quercus rubra. St. 

 Croix Falls. In this collection the sporules are mostly 18-22/* 

 long, continuous. 



Gloeosporium caryae Ell. & Dearn. On Carya cordiformis. 

 Trempealeau and St. Croix Falls. In these collections the acer- 

 vuli are epiphyllous. This fungus received a second description 

 under the same name by Ellis & Everhart, hence the citation of 

 these authors in the provisional list.
