Disc immersed, encircled by a dehiscent, substellate, 

 distinct, suberose, friable ring ; asci cylindrical, slender 

 elongated ; sporidia 8, filiform. (Plate XII. fig. 74.)

 thin membrane, which is wholly adnate to the matrix, 

 at first closed, then open ; the mouth encircled by a 

 superficial, more or less persistent, usually white ring. 

 The asci are very long and slender, splitting at their 

 summits, allowing the still slenderer, nearly equally long, 

 filiform sporidia to escape. S. Berkeleyana is sometimes 

 superficial.
