Stromata numerous and generally thickly scattered, snrroimdinu 

 and extending for some distance along the limbs, orbicular or ellip- 

 tical at base, and 1 1-3 mm. broad, obtusely conical above and, for the 

 most part, distinctly pustulate-prominent, covered by the closely 

 adherent epidermis, which is pierced by the erumpent disk or stel- 

 lately cleft with the laciniae adhering, Perithecia 4-20 (mostly 6-10).. 

 subcircinate in the unaltered substance of the inner bark, about J mm. 

 diam., and mostly not crowded, necks slender, decumbent, with their 

 large, depressed-spherical, black ostiola erumpent around the margin 

 of the small, whitish disk or irregularly arranged, crowded and obliter- 

 ating the disk. Sometimes the epidermis is slightly depressed just 

 around the disk, with a circle of slight protuberances indicating the 

 position of the subjacent perithecia. Asci (p. sp.) 40-55 x 12-15 ju>, 

 4-8-spored y with a slender, stipe-like base 30-35 // long. Sporidia 

 conglomerate or subbiseriate, allantoid, hyaline, slightly curved, 

 obtuse, 14-24 x 3-5 jut in the 8-spored asci, in the 4-spored asci, 24-36 

 x 5-8 IJL. 



On dead limbs of various deciduous trees, common, at least 

 throughout the northern U. S. and Canada. 



We have specc. from Canada on ash, hawthorn, elm, oak, bass- 

 wood and hickory; from Iowa, on Pymis coronaria; from Montana, 

 on Shepherdia Canadensis; from New York, on Acer rubrum; from 

 Nebraska, on Sambucus; from New Jersey, on Nyssa, Liquidambar,
