Preliminary List of Manitoba Fungt. 93 
been made in Manitoba, except in the case of Professor Macoun’s 
list of lichens. References to various Manitoba fungi are, how- 
ever, given in “Researches on Fungi’ and other papers by 
im. H. R. Buller. 
The nomenclature used varies somewhat: Dr Kauffman was 
followed for names of Agarics, Dr Overholts for Polypores, and 
Saccardo for many fungi. In general the writers have endea- 
voured to use the standard names for the fungi included. The 
names of hosts are taken largely from Britton and Brown's 
Flora. 
Dr Davis has furnished the description of a new Cercospora 
for this list, and Mr Lloyd has considered a Ptychogaster sent 
him to be a new form. Two or three species are recorded for 
the first time for North America. In almost every case, however, 
the fungi found were those which had already been described 
for North America. Further and more critical search will of 
course extend this list, and the writers believe that a survey 
of Northern Manitoba will reveal a number of interesting fungi. 
This list contains 574 fungi, as follows: Myxomycetes 34, 
Bacteria 8, Phycomycetes 20, Ascomycetes 62, Imperfect fungi 
38, Smuts 20, Rusts 80, Polypores 63, Agarics 108, Thelephora- 
ceae 36, other Basidiomycetes 57, Lichens 48.
