Stroma broadly effused, mottling the surface of the bark and the 

 wood with oblong or variously shaped spots from 1 mm. to 1 cm. or 

 more long, with the black, limiting line penetrating the wood. Peri- 

 thecia gregarious, subglobose. of medium size, covered by the bark, and 

 more or less sunk in the wood. Ostiola erumpent, straight, slender, 

 spine-like, often 1 mm. long, but quite as often barely perforating the 

 bark. Asci fusoid. 8-spored, 50-60 x 9-10 p. Sporidia biseriate. 

 short-fusoid, uniseptate and constricted, 12-13 x 4J-5 //, 4-nucleate. 

 -ubobtuse, hyaline.

Stroma mostly broadly effused, covering the entire stem and

branches, closely covered by the unaltered epidermis, through which 

 is visible the black, circumscribing line of the stronia. Perithecia 

 tolerably large, irregularly scattered or gregarious, or even collected 

 2-4 together in valsoid groups, at first globose, but soon depressed, 

 nestling in the bark, their apices more or less prominent, and raising 

 the bark into little pustules, their very short ostiola erumpent through 

 cracks in the epidermis, but scarcely projecting. Asci narrow-clavate. 

 sessile, 8-spored, 52-60 x 8 /JL. Sporidia biseriate or oblique, narrow - 

 fusoid, subobtuse at the ends, cylindrical, straight, hyaline, 1-3-septate, 

 4-nucleate, not constricted, 16-18 p. long, 3 // thick.

Densely gregarious, perithecia subcuticular, depressed-hemispher- 

 ical, 200-250 /JL diam., rugose. Ostiola cylindrical, obtuse, minutely 

 roughened, 150-200 JJL long. Sporidia biseriate, oblong-fusoid, 2-4- 

 nucleate, and mostly constricted, hyaline, slightly curved, when younu 

 faintly appendiculate at each end, variable in length, 12-18 // long. 



On galls on dead canes of Rubus villosus, and on the canes them- 

 selves, Xewfielcl, N. J. 



The parts occupied by the fungus appear to the naked eye as it' 

 covered with a black pubescence, so thickly are they covered with tin- 

 hair-like ostiola.
