Septoria cylindrospora n. sp. 
Pyenidia scattered, black, globose to lenticular with cellular 
walls, 125-200 in diameter; sporules hyaline, cylindrical, 
straight or slightly curved, 18-30 x 2-3/a. On calyces, bracts, 
leaves, and upper part of stems (especially on the south side) of 
Pedicularis canadensis. Solon Springs, June 1914. Under io¬ 
dine the sporules show a median division. I have not seen Bhab- 
dospora sceptri Karst, of which this may be only a form differing' 
in the straight cylindrical sporules. This might be referred to 
Ascochyta. 
Septpria xanthiifolia Ell. & Kell. On Iva xanthif olia. Alma. 
PJileospora celtidis Ell. & Mart. On Celt is occidentaiis. Wy- 
alusing. In this collection the sporules attain a length of 100/a, 
or more and become 8 or more septate. 
Gloeosporium trifolii Pk. On Trifplium pratense. Minocqua. 
Abundant at one station. 
Colletotrichum graminicolum (Ces.) Wilson. On leaves of 
Echinochloa crusgalli. Devils Lake. Setae 50-100 x 5-6/a, spor¬ 
ules 16-24 x 3%-6/x. Collected also at Alma and Maiden Pock. 
COLLETOTRICHUM SORD1DUM n. sp. 
Spots on the upper surface of the leaves varying from orbicu¬ 
lar to irregular, light brown with a darker margin, 5-15 mm. in 
diameter to indefinite and more or less confluent into indefinite 
areas, cinereous above from loosened cuticle, on the lower leaf 
surface indefinite; acervuli epiphyllous, scattered, small, flat; 
sporules hyaline, cylindrical with rounded ends, straight, 21-33 
x 6 /a ; setae dark brown to black, mostly incurved, 50-75 x 3-6/a. 
with a septum near the base below which the seta is abruptly 
dilated. The affected portions of the leaves become quite fri¬ 
able. On Menispermum canadense, Wisconsin river bottom op¬ 
posite Bridgeport, July 31, 1914. As there is a possibility that 
this may connect with Gloeosporium sordidum Speg. of South 
America I have used the same specific name. 
Didymaria astragali (Eil. & IIol.) n. comb. {Bamularia astrag¬ 
ali, Ell. & Hoi.) On leaves of Astragalus canadensis. St. Croix 
Falls.
