 biseriate, clavate-oblong, continuous, hyaline, 6-8x2J-3 // sporidia. 

 The subiculum appears to be obsolete, the perithecia being immersed 

 in the hymenium of the host. As no notes were taken from the fresh 

 specimens, the color of the perithecia can not be certainly stated, but 

 in the dry specimens they are nearly or quite black.
