Very variable. When young, pustuliform, black, small, forming, 

 like some of the other species, a conceptacle subimmersed in the 

 fibrous bark. Ostiola umbilicate, prominent, cylindrical. Finally the 

 stromata become confluent for one or two inches in length, bursting 

 out through longitudinal cracks in the bark, the apex of the concep- 

 tacles truncate above, and on this truncate surface are seen the short, 

 thick, irregular ostiola. Perithecia of medium size, immersed in a 

 cinereous flesh-colored stroma, 



Orj dead limbs of Bignonia, Carolina (Schw.). 



Sporidia (fide Cke. Grev. 1. c.) olive-brown, uniseptate, 15x8 //.

Perithecia gregarious, covered, at length erumpent through the 

 fissured bark, black, obtuse. Asci subcylindrical. Sporidia subellip- 

 tical, uniseptate, slightly constricted, brown, 28-30 x 10-12 //.

 (Curtis).

Stroma effused, thin, black. Perithecia small, oval, crowded, at 

 length flattened at the apex, opake, at length botryoid-aggregated, sub- 

 confluent. Asci cylindrical, 8-spored. Sporidia elliptical, uniseptate, 

 scarcely constricted, brown, 15x 7 ^. 



On bark, United States (Cooke, 1. c). 



Has the habit of Botryosphceria, with the fruit of Valsaria. In 

 Grev. Xni, p. 108, this is placed in a section having hyaline sporidia. 

 Not having seen a spec, we cannot say which is right.
