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

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

 rranged, white inside. Ostiola obsolete. 



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



dec. thick. 



This seems doubtfully distinct from D. vernicosa.

Sphixria loculaia, Lev. 1. v.-. 



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

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

 3al. Asci and sporidia as in the other species. Stipe short, some-

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

 ;arnose-suberose and clothed with a pulverulent, cinereous, conidial 

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

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

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

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

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

 md tough, at length very brittle and hollow, centrally attached. 

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

 )stiola only projecting. Asci narrow-cylindrical, pedicellate, 8-spored, 

 250 X 8-10 fi (p. sp.). Paraphyses slender, evanescent. Sporidia 

 jbliquely uniseriate, fusoid, inequilateral or slightly curved, finally 

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

 iccount of this fungus.
