58 JOURNAL OF THE 



spores in a young condition may sometimes be hyaline. 

 Prof. B. T. Galloway, Chief of the Division of Veg. 

 Pathology, has kindly permitted me to examine the speci- 

 men of Hebninthosporium Petersii in Rav. Fung. Am., 

 166, from Smilax. It is identical with my specimens from 

 Alabama. I have no doubt that B. & C.'s specimens on 

 Smilax are the same. I have not seen the fungus on 

 LauriLS Baisoin and I have arranged the synonymy for the 

 specimens on Smilax.
