Peritliecia scattered or here and there gathered in groups of 3-5 

 or more, but not crowded, small, sunk more or less in the woody stem, 

 which is sometimes blackened on the surface, but is not penetrated by 

 any black line or otherwise discolored within. Ostiola erumpent, 

 conical or short-cylindrical, rather stout. Asci clavate-oblong, about 

 60x6 /i. ' Sporidia biseriate, fusoid, 4-nucleate, curved, hyaline, 15- 

 20 X 2i-3 n.

Stroma effused, at length blackening the surface of the stem, which 

 remains unchanged within. Perithecia scattered, small, pale at first, 

 buried moi-e or less deeply. Ostiola acute and, when well developed, 

 J-| mm. long, cylindrical, slender. Asci oblong, sessile, 40-55 x 

 6-7 fi. Sporidia mostly biseriate, navicular-fusoid, mostly acute, both 

 ends usually slightly curved in opposite directions, yellowish-hyaline, 

 12-16 X 3-3| fx, uniseptate, scarcely or only slightly constricted.

Found mostly near the base of the stem. Higher up are perithe- 

 cia filled with stylospores scarcely distinguishable from the ascospores.

Stioma more or less effused, often covering the stem for a consid- 

 erable extent, surface mostly blackened, sometimes not discolored or 

 only gray, internally composed of the unaltered substance of the stem 

 surrounded by a thin, black layer. Perithecia scattered, or here and 

 there approximated, entirely buried, mostly a little depressed, about 

 I mm. diam., contracted into a slender neck, erumpent in a cylindrical 

 or conic-cylindrical ostiolum, about as in D. orthoceras. Asci oblong- 

 clavate, sessile, 8-spored, 40-50 // long, 6-8 fj. wide. Sporidia biseriate, 

 fusoid, ends subacute, uniseptate, mostly slightly curved, scarcely con- 

 stricted, 10-14 x3-3| fjL (mostly about 12 /i long).
