Stromata convex-hemispherical, about 2 mm. diam., often 2-3 con- 

 fluent, covered by the loosened epidermis. Perithecia numerous, 30 

 or more closely packed in a single layer in the bottom of the stroma, 

 small, necks slender, with their small, black, shining ostiola erumpent 

 in a brown, abruptly elevated disk which is soon obliterated. Asci 

 clavate, 26-40x5-6 //, 8-spored. Sporidia biseriate, cylindrical, hya- 

 line, slightly curved, with a nucleus in each end, 6-8 x IJ-lg // (10 /j. 

 long, Cke.). 



On oak wood cut and piled for market, Newfield, N. J. 



The stromata are numerous, and the tufts of erumpent, but scarcely 

 exserted ostiola loosen the epidermis. The surface of the inner bark 

 is of a uniform, dull black color, but there is no circumscribing line.

Pustules small, erumpent. Perithecia black, subglobose, nestling 

 in the bark, surrounded by the fissured epidermis. Ostiola subrugose. 

 truncate, emerging in an orbicular disk. Asci clavate, subsessile, short. 

 8-spored. Sporidia allantoid, smoky-hyaline, 8x2 //.

Erumpent, prominent, truncate. Perithecia 6-8, nestling in the 

 inner bark, globose, black, the necks united in an orbicular or ellipti- 

 cal disk which is pierced by the ostiola, and generally pulverulent on
