NOTES ON PARASITIC FUNGI IN WISCONSIN—VII. 
J. J. Davis 
The season of 1918 was not favorable for the parasitic fungus 
flora, apparently because of lack of precipitation. Even forms 
that occur on marsh or swamp plants seem to require rain for 
full development. 
Plasmopara humuli Miyabe & Takahashi was found on Humulus 
Lupulus in 1918 at Bruce. This adds to the probability that it 
is indigenous in Wisconsin. 
[Also found in small quantity at Little Suamico on the west 
shore of Green Bay in September 1921.] 
Of a collection on Smilax hispida referred to Stagonospora 
smilacis (E. & M.) Sacc. it was noted that in some of the pycnidia 
the sporules were 15-20 x6-7y, somewhat fusoid, hyaline, con¬ 
tinuous, while in other pycnidia they were elliptical to ovate, sub- 
fuligineous, 10-13 x 6-7^ and many of them uniseptate. 
In “Notes” IV (p. 68) reference was made to a Septoria on 
leaves of wheat which was referred to S, glumarum Pass. In a 
collection on Triticum vulgare (cult.) made at Bailey’s Harbor, 
July 28, 1918, the pycnidia are located in the somewhat paler 
central portion of more or less elongate brown spots which are 
surrounded by a yellow discoloration of the leaf. The somewhat 
depressed, ostiolate pycnidia are 90-130/x in diameter, the sporules 
15-26 x 3 p, appearing continuous but showing 1-3 divisions of the 
endoplasm when stained. Septoria fusispora Died, may be the 
same fungus (Kryptogamenflora der Mark Brandenburg 9: 467). 
The delicate spore tendrils have a pink tinge. 
In the provisional list two species of Septoria were given as 
occurring on Viola in Wisconsin. In the Enumeration and De¬ 
scription of North American Septorias Dr. George Martin gave 
399
