Preface 
When in 1917 the late Mr. James M. Macoun, C.M.G., Chief of the 
Division of Biology of the Museum branch, Department of Mines, arranged 
with the author of this bulletin to have a survey made of the mushrooms 
and other fleshy fungi of Ottawa district, he did this because there 
was afforded the opportunity of utilizing the services of a competent and 
enthusiastic collector in an investigation of varieties of plant life that are 
rather imperfectly known scientifically, and concerning which it was desir- 
able that more accurate information should be available. 
Mr. Odell has up to date placed on record nearly 400 species and 
varieties of mushrooms and other fleshy fungi from Ottawa district. 
Although there are, no doubt, still more to be discovered, it is felt that the 
list is sufficiently complete to warrant its publication. 
It should also be emphasized that although the list herewith presented 
deals only with the species in Ottawa district, a large number of them 
have such a wide geographical distribution that the publication of the list 
will no doubt prove of interest not only locally but to students of fungi 
all over eastern Canada, as well as to specialists outside the Dominion.
