I am indebted to Mr. H. G. MacMillan of the Wisconsin Ag¬ 
ricultural Experiment Station for identification of specimens in 
this group. 
Stagonospora intermixta (Cke.) Sacc. To this species I have 
referred specimens of which the following notes were made. On 
elongated light brown dead areas which soon spread over the 
whole leaf; pycnidia epiphyllous, scattered, dark brown, glob¬ 
ose or depressed-globose, 60-100/* in diameter; sporules at first 
hyaline and cylindrical becoming acute at one end with a cen¬ 
tral row of small guttulae, finally septate and tinted, 26-52x3-4/*. 
On Phalaris arundinacea. Devils Lake, Wisconsin, August 5th, 
1913. The pycnidial wall is usually thin at the base while the 
outer portion is thick and blackened. 
Sept oria agrimoniae-eupatorii Bomm. & Rouss. On Agri- 
monia gryposepala. Potosi and Glen Haven. 
Septoria cacaliae Ell. & Kell. On Cacalia atriplicifolia. Lake 
Mills. Oct. 26, 1901. 
Septoria silphii Ell. & Evht. On Heliopsis scabra. Madison. 
Sporules 26-36 x 1/*. This species was described as having 
sporules 35-50 x ly, but in specimens on Silphium perfoliatum 
collected at Madison they are but 26-36 x ly. The spots tend to 
become white and arid with age. 
Entomosporium maculatum Lev. var. cydoniae Sacc. On 
Pyrus Aucuparia. Devils Lake. Sporules 20(16-23) x 8(6-10)/*. 
Gloeosporium septorioides Sacc. On Quercus rubra. Devils 
Lake. In these specimens the sporules have a narrow median di¬ 
vision of the cytoplasm which is sometimes apparent without 
staining. 
Gloeosporium robergei Desm. On Ostrya virginiana. Somers, 
South Milwaukee and Devils Lake. In all the specimens which 
I have collected on this host the cuticle on the upper surface of 
the spots is rugose forming white dendritic lines. It is labeled 
var. dendriticum in our herbaria.
