Sporules from loculi of Phyllachora on Calamagrostis cana¬ 
densis have been observed. They were fusoid-cylindrical, guttu- 
late, continuous, 16-20 x3/x. Doubtless a spermogonial state. 
Septoria bromi Sacc. On Bromus altissimus. Bruce. The 
record of the occurrence of S. graminum Desm. on this host in 
“Notes’’ V (p. 694) was based on a very poor specimen and should 
be canceled. 
Septoria verbenae Rob. & Desm. 
On Verbena bracteosa. Wild Rose. Sporules 35-75 x 
Septoria atropurpWea Pk. 
On Aster puniceus. Sullivan and Spooner. 
Sacidiwm ulmi-gallae Kell. & Sw. 
On TJlmus americana. Wild Rose. 
Record has been made of the occurrence of Gloeosporium salicis 
West, in Wisconsin on willows of European origin. A correspond¬ 
ing Melanconiacea on the upper surface of the leaves of native 
willows, however, I am referring to Marssonina kriegeriana (Bres.) 
Magn. 
Collections have been made as follows: 
On Salix longifolia. Madison. 
S. discolor. Racine. 
S. cordata. Shiocton. 
S. syrticola. Two Rivers. 
S. petiolaris. Arcadia. On this host the acervuli are hypo- 
phyllous, sporules 13-17 x 314 - 6 /*,, usually curved, finally 
septate toward the narrower end. 
Marssonina rubiginosa (Ell. & Evht.) which was recorded in 
“Notes” V is apparently merely a form of this. Examination of 
a portion of the type collection of Marsonia nigricans Ell. & Evht. 
(Proc. Acad. Nat. Sci. PJiila. 1891, p. 84) kindly sent by Pres. 
Dearness leads me to believe that the host is Populus balsamifera 
and the parasite Marssonina popnli (Lib.) Magn. 
Piricularia grisea (Cke.) Sacc. 
On Leersia virginica. Blue Mounds and Maiden Rock. Leersia 
oryzoides. Millston. Leersia sp. indet. Hixton. Setaria italica 
(cult.) Madison. This fungus appears to be divided into several 
physiological races. P. oryzae Cav. and P. setariae Nishikado have
