SOME ERYSIPHE^E FROM CAROLINA AND 



ALABAMA. 



BY GEO. F. ATKINSON. 



During the past four years the writer has collected occasionally 

 species of this group in parts of North and South Carolina and 

 Alabama, some of which are of interest in showing the extended 

 range of species found elsewhere, while others throw some light 

 on the relationships of imperfectly known forms. 



The descriptions of the species enumerated are in reality notes 

 upon the forms collected in tliis comparatively circumscribed 

 region, so that in some cases the specific description may seem to 

 lack the broader character which would be given from a descrip- 

 tion based upon a comparison of specimens from widely different 

 latitudes and on a much greater variety of host plants. 



The paper is not monographic, but professes the simpl char- 

 acter of being a contribution to a knowledge of some juthern 

 forms. Bearing this in mind, it is hoped the small contribu- 

 tion given will not be devoid of interest to students of this 

 fascinating group of microscopic plants. 



A list of the works consulted will be found at the close of 

 the article. In prescribing the limitations of the species I have 

 tried to follow the admirable work of Professor Burrill on the 

 Erysiphece of Illinois* so far as consistent with the characters of 

 the specimens.
