 anything to its history. The apices of the branches of the speci- 

 men examined are punctate with dark spermogones.

 compressed, stramineous to virescent, occasionally blackening; 

 cortex glabrous, dull, striate, often sulciform; primary branches 

 remotely dichotomous, subterete to compressed, tortulous (max. 

 length 45 cm.) ; secondary branches subremotely dichotomous, 

 subterete, tortulous ; fibrils capillaceous, terete. Apothecia not

 shire (Tuckerman) to Greenland (Macoun, Stizenberger) on the 

 Atlantic coast, though I have seen only reduced examples from as 

 far north as Newfoundland. The intermediate records are Maine 

 (Eckfeldt) , Cape Breton (Macoun) , Anticosti (Macoun) , New- 

 foundland (Eckfeldt, Arnold), Labrador {Eckfeldt, Macoun, 

 Cummings) . Dr. Eckfeldt has also recorded it from New Jersey,
