Perithecia scattered, suberumpent, depressed-hemispherical, ^-| 

 mm. diam., membranaceous, black, ostiolum not prominent. Asci 

 oblong or ovate-oblong, sessile, mostly subattenuated above, but obtuse, 

 70-76 X 15-20 fx. Paraphyses not abundant. Sporidia mostly biseri- 

 ate or irregularly crowded, oblong-fusoid, 1-3-septate, hyaline, 22-25 

 x6-8/^.

Perithecia coriaceo-carbonaceous, black, rather thin-walled, \-\ 



mm. diam., sometimes 2-3 united, at first covered by the fibers of the 



bark, the upper half at length projecting and nearly bare. Ostiolum 



subtuberculiform, obtuse, broad. Asci clavate-cylindrical, 80-115 x 



12-15 /i, with filiform pai'aphysCvS. Spoiidia uniseriate or partly bi- 



seriate above, rather acutely elliptical, endochrome, 3-times divided, 



hyaline, 18-22 x 7-9 /i. The upper part of the peiithecium at length 



falls away, leaving the black, cup-shaped, hemispherical base bedded 



in the bark. Closely allied to M. leiostega, Ell., which is scarcely 



distinct fi-om M. corticola, Fckl. It differs however in its denuded 



perithecia, longer and broader asci, and rather longer sporidia. The 



sporidia of M. leiostega, are mostly 14-18 x 7-8 ji. very few reaching 



20 fi long.

Perithecia covered by the epidermis, densely and widely grega- 

 rious, so as to blacken the stem, globose-depressed, small, 120-180 n 

 diam., papillulate, finally collapsing. Asci cylindric-clavate, 90-100 x 

 16 u, sparingly paraphj-sate, very short-stipitate, 8-spored. Sporidia 

 biseriate or obliquely uniseriate, oblong-fusoid, at first broader and 

 surrounded with a hyaline envelope, 6-nucleate, becoming 6-septate, 

 the third cell thicker, constricted in the middle, 28-30 x 6J-7J [i, fre- 

 quently curved.
