the epidermis (whicli is not split or torn) in little fascicles, with 

 numerous light brown, coarse, tow-like hairs as long as or a little longer 

 than the ostiola, and causing the surface of the .bark to appear as if 

 covered with clumps of miniature, brush-like hairs. The ostiola are of 

 a carbonaceous character, as they readily break square off, so as to 

 appear truncate. The clusters of perithecia lie in parallel series, or 

 lines, extending for three or more centimeters, and the epidermis, 

 which remains closely attached, is scarcely eleva:ted by the subjacent 

 perithecia. Asci clavate, with a slender, thread-like base, spore-bear- 

 ing part 18-22 x 5 fi, with the upper part broader and obtuse. 8po- 

 ridia cylindrical, hyaline, or with a» faint yellow tint, rather strongly 

 curved, about 5 x 1 /i, with a faint nucleus near each end.

 (Langlois), on bark of Fraxinus, South Carolina (Ravenel). 



Saccardo finds conidia on the hyphomycetous growth ai'ound the 

 ostiola, obovoid, 6x5-6 [i. dark brown, 1 -nucleate. Harpographium 

 fasciculatum, Sacc. (N. A. F. 2000) he considers the macroconidial 

 stage. The species is widely diffused in Europe and probably here.

Stroma broadly effused, originating under the bark, which is soon 

 thrown off. Perithecia globose, black, thickly scattered, sunk in the 

 wood, the surface of which is not swollen or pustulate but even, atten- 

 uated above into short necks with conical, black, shining ostiola 

 rounded- and smooth at the apex, barely erumpent but not exserted. 

 Asci fusoid, long-stipitate, p. spi 22-26 x 3i-4 fi. Sporidia all^intoid, 

 pale olivaceous, slightly curved, 5-6 x 1 //.

Specc. on Acer campestre, found by Saccardo in Italy, have the

Stroma elongated, reaching one foot long and one inch wide, at 

 first subimmersed and covered by the cinerascent fibers of the wood, 

 finally entirely emergent, with an irregular outline, surface rivulose 

 and undulate, and when old narrowly sulcata longitudinally, and col-
