This is closely allied to D. pustulata, Desm., but the specimens 

 of that species in Desm. PI. Crypt. 1755, have the sporidia fusiform, 

 4-nucleate, acute, and only 3-3| (i thick, and the black stratum en- 

 closing the stroma is thicker and harder, both perithecia and stroma 

 coming off with the bark, which is not the case with th Canada 

 specimens.
