Stroma valsoid, pustuliform, covered by the epidermis which is 

 pierced by the ostiola, sometimes much reduced or wanting. Perithecia 

 mostly bedded in the unaltered substance of the inner bark, subcirci- 

 nate, with converging necks united in an erumpent disk. Asci 4-8- 

 spored, mostly without paraphyses. Sporidia hyaline, ovate or ellip- 

 tical, continuous (Cryptosporella) , oblong, fusoid, or cylindrical, con- 

 tinuous (Eucryptospora), septate or pseudoseptate (Calospora).

The following diagnosis is from Grev. XIII, p. 4(): 

 Receptacle somewhat swollen. Groups of perithecia 2-4 lines 

 across, surrounded by the ruptured epidermis. Perithecia black or 

 -cinereous. Ostiola very long, round, divergent, three times as long as 

 the diameter of the perithecia. Asci 8-spored. Sporidia subelliptical.
