A SUPPLEMENTARY LIST OF PARASITIC FUNGI OF 
WISCONSIN. 
BY J. J. DAVIS, RACINE, WIS. 
In the Transactions of the Wisconsin Academy of Science 
Arts and Letters, Vol. VI., there was published A Prelimin¬ 
ary List of the Parasitic Fungi of Wisconsin, by Wm. Trelease, 
Sc. I). It was presented to the Academy in December, 1882. 
Since that time considerable additional material has been 
collected which, it would seem, ought to be used for the exten¬ 
sion of the list. 
To this end, Prof. Trelease has kindly contributed notes and 
specimens, Prof. A. B. Seymour of Cambridge, Mass., sent me 
his Wisconsin collections, other collectors have aided me with 
notes and specimens and my own collection has been used. 
Owing to lack of time, Prof. Seymour has been unable to work 
up his Wisconsin specimens and they were largely undeter¬ 
mined. I have identified as many of them as I was able to, but 
a considerable number remain until he shall find time to name 
them. Of course these lists do not approach, a complete enum¬ 
eration of the Parasitic Fungi of Wisconsin, and it is to be 
hoped that those who collect within the limits of the state will 
work towards the completion of the undertaking so well begun 
by Professor Trelease. The name of the collector is given in 
all cases except when the specimens were collected by me and 
are preserved in my herbarium. 
The notes on distribution and quantity refer to the vicinity 
of Racine, and are jotted down from recollections of field exper¬ 
ience, which, as every collector knows, varies much from year 
to year. The words common and rare are used with reference 
to distribution, abundant and scarce with reference to quan- 
tity. 
In addition to Profs. Trelease and Seymour, I desire to ex- 
press my ooligations to Mr. E. W. D. Holway of Decorah,
