Peritbecia scattered, suberumpent, depressed-hemispherical, |-| 

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

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

 70-76 x 15-20 /i. Paraphyses not abundant. Sporidia mostly biseri- 

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



x6-8/;.

 Metasphceria cavernosa, Sacc. Syll. 7030. 



Peritliecia 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 ju, with filiform paraphyses. Sporidia 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 perithecium 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 from M. corticola, Fckl. It differs however in its denuded 

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

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

 20 p long.

Peritliecia covered by the epidermis, densely and widely grega- 

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

 diam., papillulate, finally collapsing. Asci cylindric-clavate, 90-1 00 x 

 16 p, sparingly paraphysate, very short-stipitate, 8-spored. Sporidia 

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

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

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

 quently curved.
