Davis—A Provisional List of Parasitic Fungi. 
847 
Botanical Garden, St. Louis, Mo., and in part in my own her¬ 
barium which is now at the University of Wisconsin, with a 
few exceptions noted in the original entries. The more recent 
additions are based on specimens in the herbarium of the Uni¬ 
versity of Wisconsin or in that of the Wisconsin Agricultural 
Experiment Station, or in both. The nomenclature of the 
hosts is that of Gray’s Mew Manual of Botany, 7th edition and 
emendations made by the authors of the Manual in Rhodora 11, 
33-61, (March, 1909). The authorities for the host names 
have been omitted as they can readily be found, if desired, in 
these publications. The arrangement of the species under the 
genera is in the order in which the hosts appear in the classifi¬ 
cation and under each species its hosts are enumerated in the 
same order. 
As some time may elapse before another general list is at¬ 
tempted this one has been made as concise as possible; all 
extraneous matter in the way of notes and comments, which 
might later become superfluous, being rigidly excluded. 
It is hoped that this list will be of service both to those to 
whom the parasitic fungi are interesting forms of life with 
peculiar vital relations and to those who view them more espe¬ 
cially as disease-producing organisms and that with this new 
point of departure the acquisition of knowledge of the para¬ 
sitic fungus flora of Wisconsin will be accelerated. 
Corrections and additions will be gratefully received with 
a view to future publication. I wish to thank Dr. J. C. Arthur 
and Dr. E. D. "Kern of Purdue University for expert assist¬ 
ance in the Uredinales.
