On maple limbs, London, Canada (Dearness). 



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

 of that species in Desin. PL Crypt. 1755, have the sporidia fusiform, 

 4-nucleate, acute, and only 3-3J p. thick, and the black stratum en- 

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

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

 specimens.
