"A 



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 Isew Manual of Botany, 7th edition and 

 emendations made by the authors of the Manual in Ilhodora 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. F. D. Kern of Purdue University for expert assist- 

 ance in the Uredinalcs.
