This is closely allied to D. pu$tulata, Desm., but the specimens 

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

 4-nucleate, acute, and only 3-3^ fi 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 the Canada 

 specimens.
