Perithecia 3-6, circinating in the inner bark, decumbent, large, 

 mm. diam., ovate. Ostiola short, large, obtuse, erumpent in a small, 

 black tubercle, but not connate. The pustules are thickly scattered, 

 but the bark is only slightly raised above them. Asci oblong-clavate, 

 stipitate, p. sp. 50-75 x 8-10 ft. Sporidia biseriate, allantoid, only 

 slightly curved, smoky-hyaline, 12-18 x 3-4 ft.

Perithecia 2-4 together (mostly 3), buried in the unaltered suit- 

 stance of the bark, subglobose, black, |-| mm. diam., necks decum- 

 bent. Ostiola large, obtuse, at length perforated, short, erumpent 

 together in the form of a minute, black, flattish tubercle. Pustules 

 numerous, subseriate, only slightly raising the bark. Asci clavate, 

 p. sp. 60-70 x 8-10 ft. Sporidia crowded-biseriate, allantoid, not 

 much curved, hyaline, 12-20 x 3-4| ft, mostly 12-15 x 4 ft. Spermo- 

 gonia (Cytispora sp.), minute, 1 mm. diam., conical, multilocular, 

 grayish-black inside, opening by a single pore at the apex. Spermatia 

 allantoid, hyaline, 5-6x1 ft, on lanceolate basidia 12-15 ft long, 

 thickened below. 



6n dead limbs of Acer rubrum, New Jersey and New York. 



This is scarcely more than a depauperate form of V. quaternata.. 

 unless the spermogonia warrant its separation as a species.

Pustules small. Perithecia 4-15 in a pustule, nestling in the 

 inner bark, their necks converging and united in a small (less than 1
