Davis—Notes on Parasitic Fungi in Wisconsin—VIII. 427 
black, flattened, orbicular, astomous, irregularly rugose, 140-200/a; 
sporules hyaline, oblong to short cylindrical, 2-6 x 3^-1/x ; sporo- 
phores hyaline, filiform, straight, constipate, about 12/a long. On 
leaves of Vaccinium canadense. Tomahawk, Wisconsin, August 
25, 1919. The spots usually extend from the leaf margin to the 
midrib, but are sometimes terminal and sometimes include nearly 
the entire leaf. The clypeus is membranous and often punctulate 
as in Sacidium or finely rugulose. 
Gloeosporium bicolor n. sp. 
Spots circular to irregular, immarginate, olivaceous, sometimes 
confluent, *A -2 cm. in diameter, with a sterile, reddish brown 
central portion 2-4 mm. in diameter; acervuli hypophyllous, 
small, subolivaceous, scattered on the olivaceous portion of the 
spot; sporules, hyaline, fusoid-cylindrical, rarely curved, contin¬ 
uous, 7-26 x 3-6 /a, basidia short or obsolete. On leaves of Quer- 
cus hicolor. Chippewa Falls, Wisconsin, September 14, 1918. The 
central portion of the spot resembles that caused by Marssonina 
martini (Sacc. & Ell.) Magn. 
Gloeosporium ramosum Ell. & Evht. 
On Polygala sanguinea. Nekoosa. In this collection the acer¬ 
vuli are mostly on the stems, speedily killing the host. The spor¬ 
ules are 8-13/a long, mostly more or less lunate. 
Gloeosporium fraxineum Pk. 
On Fraxinus pennsylvanica. Mosinee. Gloeosporium irregulare 
Pk. is evidently not distinct from G. aridum Ell. & Hoi. 
Colletotrichum magnusianum Bres. 
On Malva rotundifolia. Madison (A. C. Foster). Referred to 
this species because of the host. In this collection the spots are 
not white and arid but brown and subindefinite, the acervuli 
bright cinnamon brown, the sporules 10-14 x 4-5/a, the setae less 
numerous than in typical C. malvacearum (Br. & Gasp.?) South- 
worth. A specimen on the same species of host from Maryland 
(C. A. Schwarze, May 22, 1919) bears setae up to 100/a in length. 
Spiraea tomentosa was given as a host of Septoria salicifoliae 
(Trek) in the provisional list and the character of the fungus on 
this host referred to in the appendix (Trans. Wis. Acad. 17 2 :- 
983-984). It appears to be distinct from Cylindrosporium salici¬ 
foliae (Trek) Davis, and should doubtless be referred to Cylindro- 
sporium spiraeicolum Elk & Evht. When the sporules become free 
the flagelliform basal portion is usually curved. As C. spiraei- 
colum was founded on material from Idaho I was led to re-ex-
