Cercospora flagellaris E. & M. On living leaves of Phytolacca decandra, 

 Monroe County, July 28, 1923. Kay. 3966. Our specimens show 

 conidiophores to 150 by 4 to 6; conidia 40 to 175 by 3 to 5, and to 

 12 or more septate. They are described as being 8 to 10 septate. 

 They should be described as being pluri-septate. 



Cercospora Noveboracensis E. & E. On living leaves of Vernonia No- 

 veboracensis, Monroe County, September 10, 1921. 3888. This 

 fungus defoliates the plants at the base advancing upward. Agrees 

 well with the description, except: Spots very definite, brown, with 

 dark purplish border, circular or angular, to one cm. in diameter, 

 on old leaves spreading more indefinitely, or even without spots. 

 Spores 3 to 5 by 20 to 70, wider than described, and many taper- 

 ing above as is characteristic of the genus. 



Cercospora ocnlala E. & E. On living leaves of Vernonia, Monroe Coun- 

 ty, July 1, 1923. 3954. In our specimens, conidiophores 25 to 30 

 by 4 to 5, curved, nodulose or serrate at tip, olive; spores con- 

 tinuous to five septate (mostly three septate), long elliptic to at- 

 tenuate according to size of spore, sometimes with tapering truncate 

 base, 15 to 55 by 5 to 7. On leaves with a Staaonosporium which 

 makes similar spots. 



Cercospora Ribis Earle. On Ribes rnbrnin, defoliating them, Clark 

 County, October 20, 1922. 3932. 



Cercospora Rubi Sacc. On living leaves of Rubiis, Clark County, Octo- 

 ber 20, 1922. 3935. 



Cercospora Sanf/vinariae Pk. On living leaves of Sangiiinaria cana- 

 densis, Lawrence County, July 4, 1922. 3923. Agrees unusually 

 well with the description. Our material shows spores 35 to 70 by 

 3 to 4 and many 3-septate. Some taper from enlargement above 

 base as is typical of the genus. 



Ramularia Brunellae E. & E. Agrees well. Addition to description: 

 Conidiophores sometimes aiising from a dark-colored tuberculate 

 partly immersed base. Spores 6 to 17 in length, sometimes gut- 

 tulate at the center giving the appearance of a septum. (See Jour. 

 Mycol. 1889, p. 69.) 



Ramularia decipiens E. & E. (Jour. Mycol., Vol. I, p. 70.) On Rnmcx 

 obtusifolius, Monroe County, October 20, 1920. 3817. In this ma- 

 terial the spots are numerous, brown, with small white centers, and 

 surrounded by a greenish purple border. The spores are mostly 

 12 to 25 by 4 to 6, continuous, becoming 1-septate, slightly truncate 

 at point of attachment. This species is very common in this county. 



Ramularia Plantafjinis Pk. On Planiario Ruf/elii, Putnam County, June 

 27, 1922. Blaydes. 3942. The fungus was here associated with 

 Byssocystis textilis described herein. 

 Myxomycetes.
