Additional Hosts 
Not previously recorded as bearing the fungi mentioned in Wis¬ 
consin. 
It is customary in collecting in Wisconsin to find each year sori 
of Synchytrium on an additional host at a single station and in 
small quantity and they have usually been referred to Synchytrium 
aureum Schroet. Such a collection was made July 25, 1921, on 
leaves of Acalypha virginica in the Wisconsin Kiver bottom lands 
at Lone Rock. In this collection the sori are first pale yellow be¬ 
coming castaneous with age. The galls are hypophyllous, discrete, 
hemispherical, but little larger than the sori which are globose to 
elliptical, 125-175fi in diameter with wall about 5/>t thick.

A Phyllachora forming black patches with effused ascomata on 
leaves of Panicum virgatum has been collected at Muscoda. Pro¬ 
visionally it is labeled P/i. graminis panici (Schw.) Shear although 
it differs widely in macroscopic appearance from specimens on 
other species of Panicum.
