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

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

 arranged, white inside. Ostiola obsolete. 



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

 1 dec. thick. 



This seems doubtfully distinct from D. vernicosa. 



D. loculata, (Lev.) 



Sphceria loculata, Iyev. 1. c. 



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

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

 ical. Asci and sporidia as in the other species. Stipe short, some- 

 what rough. 



On trunks, America.

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

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

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

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

 ostiola, Asci pedicellate, 8-spored, paraphysate. Sporidia ovoid- 

 fusiform, continuous, dark-colored.

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

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

 colliculose and black; s'ubstance almost gelatinous at first, then hard 

 and tough, at lerigth very brittle and hollow, centrally attached. 

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

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

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

 obliquely uniseriate, fusoid, inequilateral or slightly curved, finally 

 opake, 32-40 x 8-10 p.. Tode, 1. c, gives a very minute and accurate 

 account of this fungus.
