Apothecia gregarious or more densely crowded, at first 

 globose, becoming concave-hemispheric and resembling in gross 

 characters P. albida but much smaller, occasionally becoming 

 expanded and scutellate, reaching a diameter of 4~5 mm. ; 

 hymenium concave, becoming nearly plane, white or whitish ; 

 the excipular cells rounded or angular, giving rise to hairs which 

 are usually borne in clusters; hairs closely adpressed to the sides 

 of the apothecium, the marginal ones projecting, giving rise to 

 a delicate fringe-like border, septate, blunt at their apices when 

 young, becoming sharp-pointed as they mature, reaching a 

 length of 150-300 ju and a diameter of 10-12 /x, pale-brown; 

 asci cylindric or subcylindric above, reaching a length of 300 fx 

 and a diameter of 17 m; spores 1 -seriate, the ends overlapping, 

 ellipsoid to fusoid, filled with oil-drops, becoming sculptured, 

 reaching a length of 20-27 ij. and a diameter of 10-13 fx; spore-
