Davis—Notes on Parasitic Fungi in Wisconsin — VI. 705 
NOTES IN PARASITIC FUNGI IN WISCONSIN-VI 
J. J. Davis. 
A provisional list of parasitic fungi in Wisconsin was pub¬ 
lished in the Transactions of the Wisconsin Academy of Sciences 
Arts and Letters 17 2 : 846-984 [1914]. Notes bearing a supple¬ 
mentary relation thereto were issued through the same medium: 
18 1 : 78-109 and 251-271 [1915] : 19 : 
In the provisional list Urophlyctis major Schroet. was given 
as occurring on Rumex verticillatus. All of the Wisconsin 
specimens appear to be on R. Britannica. 
Peck should be cited as the author of the binomial Phyllosticta 
hamamelidis, not Cooke as given in the provisional list. 
The merging of Marssonina castagnei (Desm. & Mont.) Magn. 
with M. populi (Lib.) Magn. by Lind ( Danish, Fungi, 2761) did 
not surprise me and I am now using the latter name, instead 
of the former. 
The classification of Septoria on Solidago, Aster and Erigeron 
is in an unsatisfactory state and probably will remain so until 
aided by the results of investigation by inoculation methods. A 
collection on Solidago serotina (Adams, June 21, 1917) that I 
have referred to Septoria davisii Sacc. bears sporules 42-75 x 
1% - 2/a. 
The sporules of Septoria bacilligera Wint. as it occurs in Wis¬ 
consin are not typical. I find them to vary from 10-50 x 1-2/x. 
Haymaker who has made studies of Monilia at the University 
of Wisconsin considers the forms on Prunus serotina and P. vir- 
45—S. A. L.
