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 shoi't-cylindrical, with a 

 large circular opening. Asci cylindrical, 100-114 x 10-12 fi, 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 /i, obtusely pointed above and regulai^ly 

 rounded below. The perithecia are much like those of Leptosphairia 

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