buried in the inner bark which is more or less blackened, 
but without any distinct circumscribing line, their bases 
slightly penetrating the wood which is not discolored. 
Ostiola short-cylindrical or clavate-cylindrical, faintly sulcate 
or often smooth, united in a dirty black disk erumpent throng 
the epidermis which is scarcely raised. Asci (p.sp.) clavate, 
20 x 4 4, 8-spored, with a slender base, and indistinetly par- 
aphysate. Sporidia biseriate above, allantoid, hyaline 
(slightly yellowish in the mass), 3$ to 44 x 1} m, moderately

penetrating the inner bark, evenly scattered. Perithecia 
6 to 10 in a stroma, closely packed, dark brown, thick

brown ostiola united in a compact cluster erumpent through 
the closely embracing epidermis. Asci clavate-cylindrical,
