Conceptacle rather large, black, but covered, as well as the effused 

 black crust around the base, with a dirty brownish, pulverulent mass. 

 Several conceptacles are often confluent beneath the epidermis, which 

 is stellately ruptured with revolute laciniae. Perithecia rather large, 

 subcircinate, compressed in the conceptacle, surrounded by a cinereous- 

 brown stroma, with a horn-colored nucleus, necks elongated-connate. 

 Ostiola 6-12, short-cylindrical, rising tog-ether through the whitish or 

 cinereous disk, rounded and nearly smooth at the tips. Sporidia 5-6 

 xli-2//.

Conceptacle nearly free in the inner bark, making a round, sub- 

 elevated tubercle, at length erumpent through the revolute-fissured 

 epidermis. Disk dark brown. Ostiola black, subprominent, rather 

 long, densely crowded, cylindric-conical, at length deciduous. Stroma 

 in which the perithecia lie, cinereous. Diameter of the conceptacle
