Tue lichens of Eastern and parts of Northern 
Ontario have received fairly complete treatment at 
the hands of Professor John Macoun in his “ Cata- 
logue of Canadian Plants, Part WII,” to which 
acknowledgments are here made. Of the area cov- 
ered by Professor Macoun the part of main interest 
to us lies in the territory bordering on the north- 
eastern end of Lake Ontario. The southern portions 
of Northumberland and Hastings Counties, espe- 
cially in the neighborhood of Belleville and Brighton, 
have been worked over very thoroughly. West of 
Toronto some information has been contributed by 
several collectors, but most of all by Mr. James 
White, who made his collections in Snelgrove, a rural 
district of cultivated, forest, swamp, and sphagnum 
bog land lying in the vicinity of Brampton. As 
Toronto lies between the two in practically uninter- 
rupted continuity with both as regards soil, climate 
and topography, a departure has been made in this 
one group, in the absence of a list relating solely to 
Toronto, by going somewhat farther afield. Where 
the locality is not credited in the accompanying com-
