Stromata scattered, ovate-glolxise, 1-2 mm. diam., the base sunk 

 in the bark, but not penetrating to the wood, the upper part erumpent 

 and closely embraced l>y the ruptured epidermis, black outside, cine- 

 reous with a reddish tint within. Perithecia 1-7 in a stroma, ovate, 

 about I mm. high and \ mm. broad, subcircinate near the bottom of 

 the stroma, brownish, attenuated into rather long, stout necks (which 

 show as light-colored points on a cross section), terminating in stout, 

 angular, black, subpyramidal ostiola mostly converging so that the 

 erumpent part of the stroma appears deeply sulcate. Asci cylindrical, 

 short-stipitate, 200-230x18-20 ,u, with stout (3-4 ^ thick), jointed 

 paraphyses. Sporidia 4^8 in an ascus, elliptical or oblong-elliptical,
