The spec, of this species in Herb. Schw. agrees fairly well with 

 the alove diagnosis except the ostiola which are tuberculiform-hemis- 

 pherical. distinctly papilliform at first, finally perforated orirregularh 

 sublaciniate-dehiscent, and tlie peri thecia small, ovate-globose, less than 

 i nun. diam. Asci clavate-fusoid, o()-35 x 5 /JL. Sporidia subbiseriate, 

 allantoid, yellowish. 5-6 x 1^ /JL. The stroina becomes at length quite 

 superficial, forming a black crust less than 1 nun. thick, and ridged 

 like the furrows of a plowed field. Allied to E. iintum, sec. Schw.

Stroina widely effused, continuous, innate in the wood or bark, 

 uneven from the irregularly emergent, scattered perithecia, brown or 

 cinereous, becoming black. Perithecia monostichous, immersed in the 

 wood or bark which is not discolored within, more or less protuberant, 

 globose, about \ mm. cliani., necks very short or almost none. Ostiola 

 obtusely conical or subhemispherical, entire or rarely obscurely sul- 

 cate. Asci cylindric-clavate, long-pedicellate, p. sp. 40-45x4-5 //. 

 Sporidia subbiseriate, elongated, curved or nearly straight, yellowish. 

 8-12xlJ-2 /JL. Spermogonia hemispherical or subconical, simple, 

 immersed in the young stroina. Spermatia slender-cylindrical, vari-

 rirrhi, 18-22x1 //.
