147 
microns and are 4 to 9 septate. There seems to be no doubt as to the identity 
of the fungus as the remainder of the description corresponds admirably. 
Cercospora bartholomaei Ell. & Kell. On living leaves of Rhus glabra, 
summer of 1911. Sutton. 
Cercospora condensata Ell. & Kell. Summer of 1911. Sutton. 
Cercospora elongata Pk. On Dipsacus sylvestris, Harrodsburg. July 7, 
1915. Spores attain a length of 275 microns. Peck gives 50 to 150 microns. 
Cercospora kellermani Bubak. On leaves of Althaea rosea, October 5, 
1915. This species seems too closely related to C. malvarum Saece. and to 
C. althaeina Sace.. Conidiophores to 110 microns long and spores from 20 
to 152 microns. 
Cercospora plantaginis Sacc. On leaves of Plantago rugelii, Campus, 
October 5, 1915. Very common. Forms brown spots. Conidiophores as 
much as 250 microns long. Spores, 75 to 175 microns long. 
Cercospora rhoina E. & E. On leaves of Rhus glabra, Unionville, October 
Deed MI. Ve dai Pt W.. : 
Cereospora ribis Earle. On cultivated Ribes rubrum, autumn of 1912. 
Very severe on its host. 
Cereospora rosicola Pass. On Rosa carolina, Campus, October 26, 1915. 
The description of this species gives the measurement of the conidiophores 
20 to 40 by 3 to 5 microns and spores, 30 to 50 by 33 to 5 and 2 to 4-septate. 
Our conidiophores are 20 to 75 by 4 to 5 and spores 30 to 80 by 5 to 7 microns 
and are mostly 3-septate. The very dark hemispherical base from which 
the conidiophores arise, is very characteristic of this species. 
Cercospora sambucina Ell. & Kell. On leaves of Sambucus canadensis, 
Campus, October, 1915. 
Cercospora septorioides E. & E. On leaves of Rubus villosus, Harrods- 
burg, August 7, 1915. This species has many characters which place it 
near C. rubi Sace., C. rubicola Thuem. and C. rosicola Pass. The spots are 
very characteristic and the resemblance of the spores to those of a Septoria 
is very striking. 
Cereospora toxicodendri (Curt.) EK. & KE. On leaves of Rhus toxicoden- 
dron, Harrodsburg, August 7, 1915. 
Haplographium apiculatum Pk. On leaves of Hammamelis virginiana, 
Griffey Creek, October 3, 1914.
