These notes are intended to be supplementary to ‘ ‘ A provisional 
List of Parasitic Fungi in Wisconsin” published in Trans¬ 
actions of the Wisconsin Academy of Sciences, Arts and 
Letters. Vol. XVII, pt. 2, pp. 846-984. 
Plasmopara Jiumuli Miyabe & Takahashi. This was collected 
on wild Humulus Lupulus growing along the river bank at 
Racine in 1909-10 since which time the station has not been 
visited. The following notes of this fungus were made at 
Racine: Spots small, angular at first, limited by the vein- 
lets, brown-red or purplish above, below of a darker green 
than the leaf, giving the “water soaked” appearance. The 
spots are surrounded by an indeterminate yellowish discoloration 
especially early in the season, less marked as the leaves become 
firmer, and finally assume the lethal brown with the death 
of the tissues included. Conidiphores hypophyllous, grey, 
175-325x5-6 1 /2/a with usually two lateral branches each of which 
is about equal in development to the terminal portion and 1-3 
times branched, ultimate branchlets tapering, subacute; conidia 
fuligineous tinted, elliptical, somewhat acute at each end, fur¬ 
nished with an apical papilla of dehiscence, 20-33 x 12-17/x, usu¬ 
ally about 26 x 15 /x ; oospores scattered in the leaves; oogonia ir¬ 
regularly thickened, brown, subglobose, 36-40/x long, oospores 
filling the oogonia 30-33 y long. 
Asterina plantaginis Ellis. This is referred to Mycosphaer- 
ella by Theissen (Ann. Mycol. 10:2:196. (Apr. 1912). 
Asterina rxibicola Ell. & Evht. This is described by Theissen 
in the same communication (p. 195) but no new combination is 
proposed.
