which renders it practically worthless. Later Professor Trelease 

 published a list of parasitic species and collected largely in other 

 groups. These collections are at the Missouri Botanic Gardens. 

 Later collections were made by A. B. Seymour, L. S. Cheney, and 

 particularly Dr. J. J. Davis, of Racine, who has published a 

 supplemental list of parasitic species bringing the number up to 

 five hundred. Special papers bearing on this flora are as follows : 



Bundy. A partial List of the Fungi of Wisconsin with Descrip- 

 tions of new Species. Geology of Wisconsin, i: 396-401. 1883. 



Includes a list of over three hundred species, with two new 

 species.

A supplementary List of parasitic Fungi of Wisconsin. 



Trans. Wis. Acad. Sci. g: 153-188. 1892. 



Includes 233 species additional to Trelease' s list with notes.

Comparatively little has been done in the direction of local 

 studv of fungi in this state. Professor Aven Nelson has collected 

 a 'io.w species in connection with his work on the higher flora of 

 the state, and Professor T. A. Williams and David Griffiths have 

 collected largely the parasitic fungi in connection with other work. 

 Most of these collections are as yet unstudied. The only paper 

 bearing on the local flora pertains equally well to the flora of the 

 states of Montana and South Dakota.

In order to supplement the foregoing, since our southern flora 

 partakes in part of adjoining lands and our northern flora is not 

 limited by the artificial boundaries of lakes and rivers and paral-
