Ramularia acalyphae sp. nov. 



Amphigenous on spots which first appear on upper surface as 

 yellowish indefinite areas 2-3 mm. in diameter, lower surface 

 appearing faintly brownish and frosted as with powdery mildew, 

 later the central portion becomes dead and is then surrounded 

 by a circle of yellowish tissue, ultimate diameter of spots (in this 

 material) being 4-5 mm. ; conidiophores appearing first on under 

 side, later also on upper, but always more copious on lower, con- 

 tinuous, guttulate, yellowish (almost hyaline), denticulate above, 

 single or* fasciculate, 25-50X4/^; conidia pluriseptate-guttulate, 

 yellow-hyaline, cylindric to spindle-form, 20-50 X 3-4

Ramularia saururi (E. & E.) 



Described in Journal of Mycology 3 : 14 as Cercospora saururi 

 E. & E., but the conidia being unquestionably catenulate in our 

 material places the species in the genus Ramularia.
