Most of the lichens of Newfoundland and Labrador were collected 
from the following localities: Trinity Bay, on the southeastern 
coast; others from Notre Dame Bay, and a few from White Bay, 
further north from Placentia Bay to the Labrador. On the La- 
brador the collection was principally made in the Straits of Belle 
Isle, then along the coast from Battle Harbor north to Seal Is- 
lands, and thence about Sandwich and Gross waters to Hamilton 
Inlet.
