Stromata cortical, not discolored, minute, about I mm. dfam., sunk 

 to tlie wood. Perithecia 3-8. Ostiola short-cylindrical, obtuse, per- 

 forated, erumpent in a short, compact fascicle rising from the center of 

 the pulvinulate stroma, and rupturing the closely enveloping epidermis 

 in a stellate manner. Asci subcylindrical. Sporidia crowded Or bi-

Stroma mostly conical, adnate to the wood, concentrically substri- 

 ate, black, dusky inside, about 2 mm. diam. Perithecia 5-9 in a 

 stroma, sphaeroid, black. Ostiola bound together in a compact disk 

 which raises the epidermis in a pustuliform manner and ruptui'es it, 

 but scarcely rises above it. Asci sessile, cylindric-clavate, 54-58 x 7- 

 9 fi, 8-spored. Sporidia biseriate, clavate-oblong, 4-nucleate, greenish- 

 hyaline, 13-15 X 3| fi, with a short, bristle-like appendage at each end.

Stromata scattered, slightly convex, orbicular or elliptical, seated 

 on tfie inner bark and covered by the epidermis, which is raised into 

 slight pustules, but not discolored, 2-3 mm. diam., sulphur-yellow. 

 Perithecia 4-10 in a stroma, subcircinate, bedded in the bark, globose, 

 at length flattened, tolerably large, their ostiola united in a small, 

 round, or subellii)tical, erumpent disk which rises but slightly above 

 the epidermis. Asci siil)clavate or fusoid, sessile, 80-90x12-14 fi. 

 Sporidia biseriate, oblong, narrowed and rounded at the ends, septate 

 in the middle, 20-24 x 7 /i, with a small, globose appendage at each 

 end.
