Ascophore developing in the matrix, then erumpent, elon- 

 gated, narrow, dehiscing by a slit running the entire length 

 of the ascophore, gaping and exposing the whole of the disc ; 

 blackish, soft and coriaceous ; asci clavate, rather narrowed 

 at the apex, mostly narrowed downwards into a slender 

 pedicel, 8-spored ; spores very long and slender, continuous 

 or many-septate, hyaline, arranged in a parallel fascicle ;
