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

 nun. diam., membraDaceous, black, ostiolum not prominent. Asei 

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

 7<>-76 x 15-20 /A. Paraphyses not abundant. Sporidia mostly biseri- 

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

 x 6-8 //.

Peritliecia coriaceo-carbonaceous, black, rather thin-walled. J-J 

 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 

 1--15 //., with filiform paraphyses. Sporidia uniseriate or partly bi- 

 -ri-iate above, rather acutely elliptical, endochrome, 3-times divided, 

 hyaline, 18-22 x 7-0 //. The upper part of the perithecium at length 

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

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

 distinct from M. corticola, Fckl. It differs however in its denuded 

 perith<Ti;i. longer and broader asci, and rather longer Sporidia. The 

 sporidia of J/. leiostega, are mostly 1418x7-8 //, very few reaching 



20 fji long.

 surrounded with a hyaline envelope, 6-nucleate, becoming 5-septate, 

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