Ridgeway. 
Ascochyta pisi Lib. On Vida angustifolia segetalis, Barneveld 
and Ridgeway. 
Ascochyta lophanthi lycopina Davis. This has been collected on 
Lycopus virginicus and it is quite possible that other collections are 
on this species of host. 
Darluca filum (Biv.) Cast. On Puccinia asteris growing on 
Aster Tradescanti, Blue River. Two telial hosts were given in 
^ ‘ Notes VI, p. 707. 
Septoria annua Ell. & Evht. On Poa annua. Black Earth. 
(McFarland & Davis.) 
Septoria caricinella Sacc. & Roum. A specimen on Car ex chordo- 
rrhiza from Lost Lake, Vilas County (July 4, 1901) is referred to 
this species. 
Septoria polaris Karst. Specimens on Ranunculus septentrion- 
alis from Richland County opposite Muscoda are provisionally re¬ 
ferred to this species. The sporules are 20-30xl-l%ju-. 
Septoria oenotherae West. On Oenothera rhombipetala. Mus¬ 
coda. 
Septoria sii Rob. & Desm. On Cicuta hulhifera. Oconto. 
Septoria solidaginicola Pk. On Solidago patula. Cecil. Aster 
lateriflorus. Woodman. Of the latter collection it was noted ‘ ‘ not 
abundant on this host and some of the spots atypical”. 
Septoria atropurpurea Pk. On Aster paniculatus. Lone Rock. 
The strongly curved sporules range up to more than 100xl%-2/x. 
Phleospora ulmi (Fr.) Wallr. On TJlmus fidva. Richland 
County opposite Boscobel. Sporules mostly about 30x7ja. 
A Marssonina on leaves of Salix lucida collected at Shawano I 
do not distinguish from forms on Populus and have labeled it 
Marssonina populi (Lib.) Magn. The aeervuli are amphigenous 
but more abundant and better developed below where they have a 
resinous appearance. The curved sporules are 13-17x3-4/ji. A 
collection on Populus halsamifera from Little Suamico has hypo- 
phyllous subcuticular aeervuli with sporules ll-17x3%-5|a.
