IVritluria in clusters of 4-12, buried in the inner bark, which i- 

 uniformly stained, of a ]>;de slate color, their bases scarcely penetrating 

 the wood, globose, about J nun. diani., with thick, coriaceous walls, 

 black and shining within. The surface of the bark is raised into dis- 

 tinct pustules over the perithecia. and is more or less cracked and 

 pierced by the cylindrical, rough, black, 1-2 mm. long ostiola, which 

 are distinctly quadrisulcate-cleft at their tips, and issue in a little fas- 

 cicle, with their bases more or less connate, but diverging above. 

 Asci minute, 12-14x4-5 p. (p. sp.), with a slender base. Spuridia 

 crowded in the asci, yellowish in the mass, allantoid, strongly curved, 

 with a nucleus in each end, 3-4 x 1 p. (mostly not over 3| p. long).

Differs from Eutypa heteracantha, Sacc., in the absence of bristles, 

 the sulcate ostiola, and smaller sporidia. More closely allied to En. 

 xcojK.ii'ia, from which it differs in its more scattered growth, mostly 

 fewer (4-8) perithecia in a stroma, and the absence of any circum- 

 scribing line. In En. xcop<tr'm also the stromata are often seriately- 

 connate.

Pustules small (1-1 g mm.), slightly elevating the bark, numerous. 

 Perithecia 2-8 in a pustule, globose, black, \ mm. diam., necks short, 

 erumpent in a pale, furfuraceous disk which is soon obliterated. 

 Ostiola globose-conical, finally more or less distinctly radiate-cleft. 

 Asci (p. sp.) about 30 x 5 /, 8-spored. Sporidia partly biseriate, oblong- 

 fusoid, slightly curved or subinequilateral, yellowish, 5-7 x 2-2 1 a, 

 (5 p. long, Cke.).

The fasciculate ostiola rise abruptly together, but they are riot 

 elongated much above the disk. The sporidia are mostly a little 

 thicker in the middle.

Stroma depressed-hemispherical, 1J-2 mm. diam., flattened above 

 and covered by a circular blackish -gray, definitely limited disk 1-1 1 

 mm. diam.. and pierced in the center by the fascicle of deeply 4-sul- 

 cate ostiola. Perithecia 6-15 in a stroma, seated on the surface of the 

 subjacent wood, ovoid or subangular from mutual pressure. J-J mm.
