Stroma pulvinate or depressed-conical, erumpent, becoming more 

 or less superficial, black, of pseudoparenchymatic structure, often 

 reduced to a thin crust, connecting the bases of the perithecia, and 

 inconspicuous or nearly wanting. Perithecia at first sunk in the 

 stroma, often remaining so, but also finally more or less prominent, so 

 as to present a botryoidal aspect, mostly small and globose, with an 

 inconspicuous, papilliform ostiolum. Asci 8-spored, paraphysate. 

 Sporidia oblong, elliptical or ovate, hyaline, continuous.
