The fungi of boreal Maine exhibit many close relationships with 
those of the old world, particularly with those found in northern 
Europe and Siberia. This is due to the Jand connections which 
existed in the north in a former geological age when a warmer 
climate and a richer flora extended through regions now boreal. 
One of the objects in mind during my trip was the gaining of all 
possible information throwing light upon questions of geograph- 
ical distribution and the history of divergence in the North 
American and the European fungus flora. When the collections 
made have been worked over, our ideas concerning the distribu- 
tion of certain northern species will doubtless be considerably 
clearer. 
A list of the various camps made during the trip with location 
and date is here given in a form convenient for reference
