 Perithecia irregularly monostichous, globose, small, with very short 

 necks, and small, obtuse, wrinkled, conical, not sulcate ostiola. Asci 

 cylindric-clavate, long-stipitate, 8-spored, p. sp. 30-50x2-3 fi. 



On decorticated limbs, Lyndon ville, N. Y. (Fairman), Carolina

Probably not uncommon, but the specc. quoted are the only ones 

 we have seen.

 sulcate. Asci narrow-clavate, very long-stipitate, 8-spored, 30 x 5-6 ft
