Perithecia minute (80-90 u.). ovate-globose, white inside, rough 

 Mini Mack outride, mostly radiate-sulcate around the ostioluni, which is 

 not prominent and finally rather broadly perforated, densely crowded 

 .nid partly sunk in a flat, blackish-brown, subcarbonaceous stroma 

 -1 cm. across or. by confluence, more, much resembling the sterile 

 -rroma of some Hypoxylon. Asci clavate-cylindrical. 55-60 x 10-12 ft. 

 with abundant paraphyses. Sporidia obliquely uniseriate. ovate, uni-

Stroma convex, penetrating to the wood, but not limited by any 

 I thick circumscribing line, brownish-black, whitish within, l|-2 mm. 

 diam. Perithccia 10-15 in a stroma. J mm. cliani., the upper part 

 mostly proinint'iit and free. Sometimes the stroma is wanting, the 

 perithecia being then simply cespitose or subsolitary. Ostiola obtusely 

 conical, nearly smooth or indistinctly radiate-sulcate. Asci clavate- 

 eylindrical, subsessile, 75-80x12/7., with paraphyses. Sporidia uni- 

 -eriate or subbiseriate above, ovate-elliptical, uniseptate and con- 

 stricted, hyaline and granular at first, becoming yellow-brown. 15-

 superficial. Asci cylindrical, sessile, paraphysate, 180-200x35 t u. 

 Spnridia overlapping-imiseriate or biseriate. oblong, uniseptate and

 becoming brown. 50-60 x 15-1 8 p., each cell with a large nucleus.
