mixed with yellowish-farinaceous matter. Pustules convex, 1^2 mm. 

 across, formed of the scarcely changed substance of the inner bark, 

 and not circumscribed. Asci p. sp. about 30 x 6 /*, 8-spored. Sporidia 

 allantoid, subbiseriate, hyaline, 9-12 x 1J-2 /i.

Stromata convex-hemispherical, about 2 mm. diam., often 2-3 con- 

 fluent, covered by the loosened epidermis. Perithecia numerous, 30 

 or more closely packed in a single layer in the bottom of the stroma, 

 small, necks slender, with their small, black, shining ostiola erumpent 

 in a brown, abruptly elevated disk which is soon obliterated. Asci 

 clavate, 26-40 x 5-6 //, 8-spored. Sporidia biseriate, cylindrical, hya- 

 line, slightly curved, with a nucleus in each end, 6-8 x 1 \-l\ (i (10 fi 

 long, Cke.). 



On oak wood cut and piled for market, Newfield, N. J. 



The stromata are numerous, and the tufts of erumpent, but scarcely 

 exserted ostiola loosen the epidermis. The surface of the inner bark 

 is of a uniform, dull black color, but there is no circumscribing line.

Pustules small, erumpent. Perithecia black, subglobose, nestling 

 in the bark, surrounded by the fissured epidermis. Ostiola subrugose, 

 truncate, emerging in an orbicular disk. Asci clavate, subsessile, short, 

 8-spored. Sporidia allantoid, smoky -hyaline, 8 x 2 fi.

V. piillula, B, & C. Grev. XIV, p. 47. 



Pustules small, at first covered. Asci clavate, 8-spored. Spo- 

 ridia cylindrical, slightly curved, rounded at the ends, hyaline, 8 p long.

Erumpent, prominent, truncate. Perithecia 6-8, nestling in the 

 inner bark, globose, black, the necks united in an orbicular or ellipti- 

 cal disk which is pierced by the ostiola, and generally pulverulent on 

 the margin. Asci small, lanceolate. Sporidia minute, sausage-shaped, 

 hyaline, 8-10 fi long. Spermogonia cytisporoid, disk erumpent, trun- 

 cate, pulverulent in the center, sometimes having a bilabiate appear- 

 ance. Spermatia amber in the mass, minute, linear.
