Cercospora lespedezae Ellis & Dearness 

 On living leaves of Lespedeza hirta (L.) Hornem. 

 Karner, Albany county, H. D. House, August 21, 19 19. 



Cercospora sagittariae Ellis & Kellerman 

 On living and languishing leaves ofSagittaria latifolia 

 Willd. Oneida, Madison county, H. D. House, August 26, 1918. 



Cladosporium aphidis Thumen 

 On leaves of Helianthus annuus L. Karner, Albany 

 county, H. D. House, September 9, 1919. The leaves were heavily 

 infested with aphids (Aphis helianthi Monell) , which doubt- 

 less serves as the host of the Cladosporium. All the leaves 

 contained in addition a Septoria which matches Septoria heli- 

 anthi E. & K. (in herb. Dearness), but which does not fully 

 agree with the published description. P u c c i 11 i a helianthi - 

 mollis Schw. was also frequent upon the same leaves. 



Cylindrosporium toxicodendri (Curtis) Ellis & Everhart 

 On living and languishing leaves of Rhus Toxicodendrum 

 L. Albany, H. D. House, August 21, 1919. See Mycologia, 8: 105. 



Cylindrosporium clenatidis Ellis & Everhart 

 On languishing leaves of Clematis v i r g i n i a n a L. 

 Panther lake, Oswego county, H. D. House, October T4. 



Diatrype albopruniosa (Schw.) Cooke 

 On dead branches ofQuercus i 1 i c i folia Wang. Albany, 

 H. D. House, November 23, 1919. This fungus is frequent upon oak 

 and other hosts, and this record is interesting only as a record for 

 it upon one of the oaks of limited distribution in New York. 



Diatrype stigma (Hoffm.) Er. 

 On dead decorticated branches of Opulaster p u 1 i f o 1 i u s 

 (L.) Kuntze. Albany, H. D. House, November 15, 1919. This 

 form, with the strongly cleft ostiola, was originally designated by 

 Ellis asD. dearnessei, but later he found variations between 

 it and D. stigma so numerous and gradual, that the distinction 

 could not be maintained. 



Diatrypella Frostii Peck 

 On dead branches of Acer saccharum Marsh. Oriskany 

 Falls, Oneida county, H. D. House, May 26. The same limbs yielded 

 Massaria inquinans (Tode) Fr., and Diatrype 

 stigma (Hoffm.) Fr.
