 sporidia 25-35 x 6-7 //, 5-7 -septate, only slightly constricted and ob- 

 scurely appendiculate,

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

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

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

 to the sporidia.
