authentic specimen of this species. The specimens which I have 
referred here have depressed-globose pycnidia 40-60/* in di¬ 
ameter with a round apical pore which is surrounded by a thick 
black ring. The long-fusoid sporules are 7—septate, 40-60x 
31 / 2 - 5 /*. 
Septoeia andropogonis, n. sp. Causing narrow elongated 
areas of a reddish-yellow color sometimes becoming sordid; 
pycnidia epiphyllous, subseriate or scattered, dark brown, de¬ 
pressed globose, little prominent, 75-100/*; sporules hyaline, 
straight or slightly curved, more acute at one end, becoming 2-4 
septate, 30-50x2-3/*. On leaves of Andropogon furcatus, Gas- 
lyn, Burnett Co. July 31, 1911. 
Septoria polita n. sp. Pycnidia scattered, globose, innate, 
black, ostiolate, 65-100/*; sporules hyaline, straight or somewhat 
curved, truncate to obtusely rounded at each end, becoming 3-5 
septate, 35-50x2%-3/*. On Car ex sp. indet. (stellulata?) Gas- 
lyn, Wisconsin, Aug. 4, 1911. This attacks the distal portion 
of the very narrow leaves of the host which becomes sere. The 
sporules have a very smooth or polished appearance and are not 
at all constricted at the septa. 
Septoria carpinea (Schw. ?) n. comb. Spots subcircular 
to angular, numerous, reddish brown becoming sordid in the 
center, somewhat paler below, 1-5 mm. in diameter; pycnidia 
epiphyllous, few, scattered, prominent, black, globose, ostiolate, 
about 65/*; sporules hyaline, usually curved, frequently arcuate, 
pluriguttulate, 25-40x2-3/*. On Carpinns caroliniada, Gaslyn, 
Wisconsin, Aug. 8, 1911. It seems quite possible that this is the 
fungus called Xyloma by Schweinitz and Depazea by Fries. 
Septoria Polymniae Ell. & Evht. The specimens on Polym- 
nia canadensis, collected near Somers in 1903, which I hes¬ 
itatingly refer to this species show suborbicular spots %-1 cm. in 
diameter which become brown above, darker toward the margin. 
The pycnidia correspond with those of this species. My notes 
of the size of the sporules read 40-45x1V2-2/*. 
Sacidium microspermum (Pk.) n. comb. (Septoria micro- 
sperma Pk.) On fallen leaf of Betula alba papyrifera. But¬ 
ternut, Oct. 8, 1911. Hypophyllous on indefinite brown areas 
which show a tendency to extend along the veins; basidia and
