Pustules small. Perithecia few, nestling in the inner bark. Osti- 

 ula lew. short. black, erumpent through small and mostly transverse 

 chinks in the bark, crowded or scattered. Asci lanceolate. Sporidia 

 crowded, elongated, sublinear, straight or slightly flexuons, obtuse, 

 slightly thickened at the ends, 35-75 /JL long. 



On dead alder limits, Albany, N. Y. (Peck), and California 

 (Harkness). 



Closely related to Cr. suffusa, but the sporidia are thickened at 

 the ends. The perithecia adhere to the epidermis and are torn away 

 with it.

 efflorescence of the bark, and sometimes remaining as an obscure white 

 ring, around the ostiola. Asci oblong-clavate, p. sp, 75-80 x 8-10 /JL, 

 stipitate and imperfectly paraphysate. Sporidia subfasciculate, 8 in an

The perithecia are of about the same color as in Diaporlhe

 only about 35-45 x3-3| //.
