liculose, and then quite black. Ostiola prominent on the ridges, black, 

 subcylindrical, subelongated, apices subtruncate, rugose and perforated. 

 Perithecia lather large. Bubglobose, crowded, monostiehous, covered by 



the black stroma which is whitish above. 



On wood of Lanrus, Bethlehem, Pa. (Schw.). 



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

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

 pherical, distinctly papilliform at first, finally perforated or irregularly 

 sublaciniate-dehiscent, and the perithecia small, ovate-globose, less than 

 \ mm. diam. Asci clavate-fusoid, 30-35 x5/z. Sporidia subbiseriate, 

 allantoid, yellowish, 5-6 x 1| p. The stroma becomes at length quite 

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

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

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

 uneven from the irregularly emergent, scattered perithecia, brown or 

 cinereous, becoming black. Perithecia monostiehous, immersed in the 

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

 globose, about | mm. diam., 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 jut. 

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

 8-12xl|-2 fi. Spermogonia hemispherical or subcorneal, simple, 

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

 ously curved, subsessile, hyaline, at length expelled in rose-colored 

 cirrhi, 18-22x1 //. 



On dead limbs of various deciduous trees, common.
