Obovate, erect, substipitate, outer layer laccate-crustaceous, of a 

 -Inning brown-black color. Perithecia buried in the stroma, zonately 

 arranged, white inside. Ostiola ol)solete. 



On trunks, near New York (Menaud). Stroma 1-2 dec. high, 

 1 dec. thick. 



This seems doubtfully distinct from D. vernicosa.

Sphasria loculata, L,ev. 1. c. 



Globose, substipitate, black, opake. Perithecia obovate, ini- 

 mersed in the stroma. Ostiola subprominent, shining, subhemispher-

Stroma superficial, subeffused, rather thick, determinate, at first 

 carnose-suberose and clothed with a pulverulent, cinereous, conidial 

 hymehium, finally rigid, carbonaceous, black and bare and generally 

 more or less hollow. Perithecia immersed, large, with papillifonn

Stroma superficial, subeffused, 3 cm. diam., repand, pulvinate, 

 thick (3-4 mm), surface even, white and subtomentose, finally undulate- 

 colliculose and black; substance almost gelatinous at first, then hard

Perithecia large, ovate, densely crowded, monostichous, the punctifbrm 

 ostiola only projecting. Asci narrow-cylindrical, pedicellate, 8-spored. 

 250 x 8-10 i (p. sp.). Paraphyses slender, evanescent. Sporidia 

 obliquely uniseriate, fusoid, inequilateral or slightly curved, finally 

 opake, 3240 x 8-10 /i. Tode, 1. c., gives a very minute and accurate 

 account of this fungus.
