Perithecia thickly gregarious, depressed, subconic, flattened 

 below so as to appear to be partially immersed in the substratum 

 but in reality entirely superficial, when removed leaving a ring- 

 like scar I mm. across, the diameter of the base of the peri- 

 thecium, ostiolum large, circular and rather prominent, the entire 

 perithecium covered with a brownish floccose coat or entirely 

 black, sparingly clothed with delicate erect bristles which also 

 occur on the substratum surrounding the perithecia; hairs very 

 dark brown or blackish, septate, rather blunt, 10-12 />(, in diameter 

 at the base ; asci clavate, 8-spored ; spores vermiform with blunt 

 ends, abruptly bent near the center, 8-guttulate, becoming /-sep- 

 tate, subhyaline or slightly yellowish, 50-60 X 7 ,* paraphyses 

 numerous and filiform {pi. i, f. 1-3).
