Sclerotiopsis concava (Desm.) Shear & Dodge. On Frag aria 
virginiana. Madison. Steironema ciliatum. Blue River. In the 
latter collection with the conidial form Hainesia lythri (Desm.) 
Hoehn. Connected with Pezizella lyth^d (Desm.) by Shear & 
Dodge. (Mycologia 13:135 et seq.) 
Stagonospora sparganii (Fckl.) Sacc. In leaves of Sparganium 
eurycarpum. Spring Green. 
In the provisional list Panicum depauperatum was given as 
a host of Septoria graminum Desm. In this specimen the pycnidia 
are on indefinite pale leaf areas; they are black, globose to ellipti¬ 
cal and lenticular, 100-150/x in diameter with firm walls composed 
of very small cells; the sporules are usually curved, sometimes very 
strongly so, 50-70xl-l%/x. I am now referring this to the South 
American Septoria tandilensis Speg. In his description the author 
notes resemblance to Puccinia coronata. The Wisconsin specimen 
came to me labeled Puccinia emaculata. The immersed pycnidia 
are sometimes laterally compressed. 
Septoria cenchrina n. sp. 
Spots linear, cinereous, variable in size, often confluent; pycnidia 
amphigenous, brown-black, globose to depressed-globose to elliptical 
with a thick wall which is often defective distally, 60-115/x in 
diameter; sporules filiform, continuous or indistinctly septulate, 
straight or more or less strongly curved, hyaline, 30-100xl%-3/>i. 
On leaves of Cenchrus carolinianus. Spring Green, Wisconsin, 
July 19, 1921. The longer sporules grow out through the widely 
open mouth of the pycnidium after the manner of those of Cylin- 
drosporium and the species approaches that genus but the Septoria 
condition seems to be the normal state. 
Septoria didyma Fckl. What is perhaps a short-spored form of 
this species is characterized as follows: Spots circular or sub- 
circular, brown with a raised purple border, becoming arid, about 
1 mm. in diameter; pycnidia few, pale, globose, epiphyllous, subepi- 
dermal, inconspicuous, 50-70/x in diameter; sporules hyaline, ob¬ 
long, usually curved, uniseptate, 14-27x3/m. On leaves of Salix 
longifolia. Lone Rock. 
Septoria aparines EU. & Evht. On Galium asprellum. Prairie 
du Sac. In the collection that I am recording under this name 
the pycnidia are scattered over the lower surface of the leaf
