Dicaeoma verans (Farl.) Kuntze.

It was stated in the 1915 list that the specimen on which this record was 
based (Lafayette, Tippecanoe Co., May 22, 1902, Wm. Stuart) was not 
available and the determination was doubtful. The specimen has since been 
located and deposited in the Arthur herbarium. It is found to be correctly 
determined. An earlier collection, which was overlooked, was made at 
Lafayette, July 11, 1900, by Wm. Stuart and distributed in Arthur & Hol- 
way’s Uredineae Exsiccati et Icones, No. 58a and 58d. 
Collections were also made by the writer in 1920 at two different points on 
Wea Creek, south of Lafayette, on Sept. 15 and Oct. 23.

105. The rust on Potentilla canadensis L. so common throughout the state 
and recorded as Kuehneola obtusa (Strauss) Arth. in the 1915 list has been 
restudied and its affinities determined to be with Phragmidium rather than 
Kuehneola. It is a brachy-Phragmidium and on this account, Dr. Arthur 
has erected the genus Frommea (Bull. Torrey Club 44:503. 1917) to in- 
clude this and one other species. The name is written Frommea obtusa 
(Strauss) Arth. (Phragmidium Tormentillae Fekl.). European authors in 
general do not consider the American species identical with the European. 
Those who accept this view should write the name of the American species 
Phragmidium triarticulatum (B. & C.) Farl. (Aregma triarticulatum B. & 
Oris
