Hedgcock & Long (Phytopath. 7:66-67. 1917) record culture work 



which indicates that this species is identical with C. Vernoniae. Further 



information regarding this situation is to be found in Phytopathology

 Hedgcock & Hunt (Phytopath. 7:67. 1917) have shown that a pre- 

 viously undescribed foliicolous species of Peridermium, to which they 

 give the name /*. Ipomoeae, is the aecial stage of this species.

This species represents the type of the genus Gallowaya Arth. which 

 up to the present time remains monotypic. It is in its life history a 

 short cycle Coleosporium bearing the same relation to that genus that 

 Necium Arth. does to Melampsora Cast, and Chrysomyxa Ung. to Me- 

 lampsoropsis (Schrot.) Arth., etc., as proposed in the revised classifica- 

 tion of Arthur (1. c). 



Galloway (Bot. Gaz. 22:433-452. 1896) has made a very thorough 

 investigation of the life history, pathological histology and the effect of 

 this fungus on this host. A large series of inoculations were carried out
