In addition to these, other specialists whose names are given 
have determined certain species. 
Specimens from 500 to 1000 inclusive are at the University 
of Manitoba; other numbers are at the Manitoba Agricultural 
College. Where no locality is cited, Winnipeg or its environs is 
to be understood. Where no collector’s name is given, one or 
the other of the writers made the collection; the number indi- 
cates which one. Thus, “‘Arcyria occidentalis Lister, 673L, 
343E”’ means that both specimens were collected at Winnipeg, 
No. 673 by A. H. R. Buller, part of the collection being sent 
to Miss Lister, who made the determination; the remainder is 
filed at the University of Manitoba. No. 343 was collected by 
G. R. Bisby, and part of it sent to Dr Elliott, who furnished the 
name, the remainder being deposited at the Manitoba Agri- 
cultural College. It was not considered necessary to include 
dates of collection unless they were out of the ordinary. Collec- 
tions from the Swan River Valley were made on July Ist to 
13th, 1921; from Gilbert Plains and Ste. Rose du Lac and 
vicinity, July 25th to 31st, 1921. Collections from Minaki and 
Kenora have been made principally in September and October, 
and by A. H. R. Buller unless otherwise noted. 
Where no number is given in connection with a species the 
specimen is not preserved, but its authenticity is considered 
reasonably accurate, unless a question-mark is appended. 
This list is believed to cover nearly all the species of fungi 
that have ever been collected in Manitoba. The writers have 
gone over the list of the Manitoba fungi which are at Ottawa 
and have checked over the rust and smut portions of the North 
American Flora as well as certain other publications which 
might contain references to fungi from Manitoba. Apart from 
the collections of the writers and Messrs Fraser, Conners, and 
V. W. Jackson, probably few collections of fungi from this 
province have been made. Various references to Canadian fungi 
were checked, but in practically every case no collections had
