 Atkinson. These specimens do not agree very well with 

 N. A. F. 2478, the hyphffi being much shorter and the 

 conidia not colored. The material is scanty and it does 

 not seem best to separate it. 



45. Cercospora Elephaxtopodis E. & E. Spots 

 brown with dirty yellowish indefinite border, orbicular, 

 less distinct on under surface. Hyphte epiphyllous, very 

 short, scarcely raised above the tuberculate stroma, faintly
