Perithecia covered by the epidermis, then denuded, depressed- 

 globose. Asci thick cylindric-clavate, 95-105 x 30-33 /jl, with a rather 

 thick membrane, 8-spored. Sporidia biseriate, oblong-elongated, 30-

Exsicc. Rehm Asc. 92. 



Perithecia gregarious on a dark red spot, innate and at first cov- 

 ered, but finally erumpent and partly free, brownish-black, globose, 

 collapsing and more or less flattened or even cup-shaped, 150-200// 

 diam. Asci clavate-cylindrical, 45-65 x 6-7 /jl, short-stipitate, par- 

 aphysate. Sporidia subbiseriate, narrow-fnsoid, 3-septate, slightly 

 curved, the second cell from the lower end slightly swollen when 

 mature, pale yellow, 22-25 x 2|-3 /i (45 x 2J-3 /i, Winter).

Perithecia scattered or gregarious, at first covered by the epider- 

 mis, at length bare and superficial or nearly so, hemispherical, black, 

 smooth, J-| mm. in diameter. Ostiolum short-cylindrical, with a 

 large circular opening. Asci cylindrical, 100-114 x 10-12 /i, 8-spored. 

 and surrounded with filiform paraphyses. Sporidia in a single series. 

 lying end to end, elliptical, yellow-brown, 4 septate and constricted at 

 the septa, 18-22 x 7-9 /x, obtusely pointed above and regularly 

 rounded below. The perithecia are much like those of Leptosphmruc 

 smbconica, C. & P., but the ostiolum is shorter.
