NOTES ON PARASITIC FUNGI IN WISCONSIN—VIII 
J. J. Davis 
In “Notes” IY (p. 681) it was stated that Synchytrium cellu- 
lare was confined to a very limited station from which it had dis¬ 
appeared and that it had not been found elsewhere. In 1919 it 
was rediscovered at Babcock in September, only resting sporangia 
being present. It was confined to a very limited area. [This has 
since been collected in other localities.] 
Coccochora rubi Davis was abundant at a station on Bruce Creek 
near Bruce on Rubus canadensis in 1918, but, as was so often the 
case that year, the reproductive bodies were not well developed. 
In “Notes” VI (p. 712) it was stated that the sporules of Sep- 
toria acerina Pk. were borne in acervuli as I had seen the fungus. 
Material collected at Mellen in 1919, however shows well de¬ 
veloped pycnidial walls. 
Specimens on Psedera from Wausau and from Nekoosa are re¬ 
ferable to Septoria ampelopsidis Ellis, the pycnidial walls being 
well developed and the sporules long and slender as described for 
that species. Septogloeum ampelopsidis (Ell. & Evht.) Sacc. 
seems to be the same fungus with imperfect pycnidial walls and 
shorter and broader sporules. To the description of Septoria 
ampelopsidia Ellis the author added the statement: “This ap¬ 
proaches Cylindrosporium on account of the imperfectly developed 
perithecia”. As the Septoria form may be considered the nor¬ 
mally developed state, it would be well to use Septoria ampelopsidis 
Ellis for the aggregate. 
The late E. W. Roark found, as a result of an extensive series 
of inoculations, that Septoria rubi West, includes two physiologi¬ 
cal races: one confined to blackberries (Eubatus), and the other 
to raspberries. Because of his untimely death, in the military
