The New York specc. differ from the above diagnosis (from Sacc. 

 Syll.), in having the asci and sporidia smaller; asci 75-90 x 12-15 n ; 

 sporidia 25^5 x 6-7 fi, 5-7-septate, only slightly constricted and ob- 

 scurely appendiculate.

Perithecia scattered, black, immersed, elevating and pushing 

 through the matrix with their narrow, elongated ostiola. Asci clavate. 

 Sporidia biseriate, 5-septate, with occasional longitudinal septa, con- 

 stricted, brown, each end at first furnished with a hyaline beak bent 

 at both ends in the same direction, so as to give a curved appearance 

 to the sporidia. 



On decorticated twigs. 



The above description is from Cooke's Handbook. Peck reports
