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. 



Cereospora bartholomaei Ell. & Kell. On living leaves of Rhus glabra. 

 summer of 1911. Sutton. 



Cereospora condensata Ell. & Kell. Summer of 1911. Sutton. 



Cereospora elongata Pk. On Dipsacus sylvestris, Harrodsburg. July 7, 

 1915. Spores attain a length of 275 microns. Peck gives 50 to 150 microns. 



Cereospora kellermani Bubak. On leaves of Althaea rosea, October 5, 

 1915. This species seems too closely related to C. malvarum Sacc. and to 

 C. althaeina Sacc. Conidiophores to 110 microns long and spores from 20 

 to 152 microns. 



Cereospora 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. 



Cereospora rhoina E. & E. On leaves of Rhus glabra, Unionville, October 

 3, 1914. J. M. V. & P. 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 3^ 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. 



Cereospora sambucina Ell. & Kell. On leaves of Sambueus canadensis. 

 Campus, October, 1915. 



Cereospora septorioides E. & E. On leaves of Rubus villosus, Harrods- 

 burg, August 7, 1915. This species has many characters which place it 

 near C. rubi Sacc, 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 toxieodendri (Curt.) E. & E. On leaves of Rhus toxicoden- 

 dron, Harrodsburg, August 7, 1915. 



Haplographium apiculatum Pk. On leaves of Hammamelis virginiana, 

 Griffey Creek, October 3, 1914. 



Macrosporium eatalpae Ell. & Mart. On leaves of^Catalpa speciosa.
