ARTHUR: NEW SPECIES OF UREDINEAE—XV 59 
comb. nov., N. caryophyllina (Schrank) Arth., N. verruculosa 
(Schroet.) comb. nov., and N. Silenes (Schlecht.) Arth. In 
the same manner the new species here described becomes 
Pucciniola Betheli comb. nov. The last is not correlated with 
any of the others, for besides the lack of uredinia, the teliospores 
are more globose, less thickened above, and much more strongly 
sculptur 
I take especial pleasure in naming this new and interesting 
species in honor of Mr. Ellsworth Bethel, of Denver, Colorado, 
who has given many years to the extensive collection and close 
observation of the Uredinales, mobenas throughout the 
mountainous region of western North America
