ADDITIONAL SPECIES. 
An enumeration of species not recorded in previous Wiscon¬ 
sin lists. 
662. Frankia alni (Wor.) 
Forming tubercles on the roots of Alnus incana Willd. 
Madison. (Prof. R. A. Harper.) 
663. Frankia ceanothi Atk. 
On roots of Ceanothus Americanus L. Madison. 
(Mr. E. G. Artzberger.) 
664. Synchytrium scirpi Davis. 
On Scirpus atrovirens Muhl. Kenosha county and 
Racine. Three stations are known to me where 
this fungus occurs and sometimes rather abun¬ 
dantly. 
665. Protomyces gravidus Davis. 
On Bidens cemua L. and Bidens connata Muhl., Dous- 
man; on the same species and sparingly on Bidens 
frondosa L., Racine; on Bidens cemua L., Berry- 
ville and Burlington; on Ambrosia trifida L. and 
Ambrosia artemisiaefolia L., Racine. 
Before the description of this species was published 
hut too late for the addition of a foot note I 
found it at Racine on Ambrosia trifida L. and 
soon after on A. art emisiae folia L. On the former 
host it was abundant but confined to one station; 
on the latter scarce but more widely distributed. 
In the description, which was based on specimens 
occurring on Bidens, the spores were stated to be 
30—55 microns long. In my specimens on Am¬ 
brosia trifida L. they average about 60 microns
