Apothecia gregarious or more often densely crowded, forming 

 continuous masses often several cm. in diameter, at maturity 

 scutellate with the margin slightly elevated, externally dark 

 reddish-brown and clothed with hairs which are closely adpressed 

 and not extending above the margin of the apothecium, reaching 

 a diameter of 3-5 mm. or rarely 1 cm. ; hymenium slightly con- 

 cave, plane or convex, very variable in color, ranging from pale- 

 to bright-orange or dark-brown ; hairs flexuous, brown, sparingly 

 septate, the ends blunt, of variable length ; excipular cells large, 

 rounded or angular, with brown cell walls, reaching a diameter 

 of 35 m; asci cylindric or subcylindric, reaching a length of 

 150-200 yu and a diameter of 12-14 /x, rather abruptly narrowed 

 below; spores 1 -seriate, parallel with the ascus or slightly oblique, 

 or occasionally irregularly disposed, containing one or more, 

 commonly two oil-drops, ellipsoid, smooth, hyaline, 7-10 X 16- 

 2\ fx; paraphyses enlarged upwards, reaching a diameter of 4-6 fx 

 at their apices, reddish. 



On burnt ground and charcoal beds.

Apothecia gregarious or crowded, at first subglobose, ex- 

 panding and becoming scutellate to discoid, the margin of the 

 apothecium even or irregularly wavy, externally pale-yellow and 

 clothed with a mass of rather pale hairs, attached to the sub- 

 stratum by a mass of coarse, white mycelium, reaching a diameter 

 of about 5 mm.; hymenium concave or plane, bright-orange, 

 brighter than the outside of the apothecium (the type described 

 as pale-scarlet), becoming paler in dried specimens; excipular 

 cells large and irregularly polygonal, reaching a diameter of
