 sessile to subpedicellate, 0.25 to 1,25 mm. wide, numerous, often covering the 

 small thallus patches; disk concolorous with thallus, from slightly concave 

 becoming convex, smooth or rugulose, shining, the larger ones immarginate. 

 Epithecium continuous, pale brown, 6o/z high; paraphyses coherent; hypothe- 

 cium colorless; asci clavate; spores 8, colorless, simple, oblong-ellipsoid, Sfx to 

 i^n long, 2/z to 4/i thick, juvenile spores with ends acuminate, the matured 

 more blunted; hymen, gel. with iodine blue then becoming sordid greenish, 

 KHQ— ; hypothallus indistinct. 



On bark of Lebocedrus decurrens Torr., at "Pinecrest," San Bernardino

Thallus crustaceous, subdeterminate, light creamy gray, distantly rimulose,

 thick, prominent, glistening proper margin, later convex and margin almost 

 excluded; epithecium subcontinuous, blackish blue, gradually paling downward; 

 thecium colorless or dingy pale brown, 76/i to 84^ high; paraphyses coherent 

 the tips clavate; hypothecium blackish brown; asci narrowly clavate; spores 8, 

 narrowly fusiform, both ends blunted, but one more gradually attenuate than 

 the other, straight or gently once or twice curved, 8 to 10 septate, but the septa
