THE MYXOMYCETES OF WISCONSIN 
Alletta F. Deaf.'

T3ie Mycetozoa include about 400 known species, tb© greater 
part of which are contained in the group of the Myxomycetes, 
or Slime-Moulds (the Myxogasteres of Fries,) and the smaller 
part in the group of the Acrasieae. 
The nearly 400 species are distributed among 50 genera. 
In the United States 200 or more species have been recognized. 
McBride, in 1894, reported 75 species from eastern Iowa. 
The present paper embodies the results of collections and 
studies begun in 1903. Down to the present year I have identi¬ 
fied seventy-four species of Myxomycetes collected in the state 
of Wisconsin. The specimens upon which this list is based 
are in the herbarium of the University of Wisconsin. Collec¬ 
tions have been made in relatively few localities within the 
state. A more extended search would doubtless considerably 
increase the number of species. 
In the determination of species I have consulted mostly 
Saeeardo’s Sylloge Fungorum, Lister’s Mycetozoa, Massee’s 
Myxogasteres. and Ma©bride’s North American Slime-Moulds. 
In the descriptions which follow 7 I shall refer to these works 
simply by the names of their authors. 
When in doubt in naming a specimen I have followed Mac- 
bride, except that in the cases of Fuligo sepiica Ganelin, and 
Enteridium liozeanum Wing, I have followed the usage of 
Lister which seems to me to be more nearly in accordance with 
the rules laid down by the International Botanical Congress of
