when dry, contracted above into short necks, terminated by small, 

 globose ostiola, subseriately arranged and erumpent through a small 

 crack in the bark. Asci (p. sp.) 80-85x15 fj.. Sporidia biseriate, 

 oblong-elliptical, hyaline, faintly subglobose-appendiculate and granu- 

 lar at first, becoming brown and 2-septate, and slightly constricted at 

 the septa, 25-30 x 10-14 //. Pycnidia central, bearing cylindrical 3- 

 septate, hyaline stylospores, 40-55x10-12 [i, on short basidia. 



On bark of dead Acer spicatum, London, Canada (Dearness). 



The drawing was made from a young specimen and does not show 

 the two septa in the sporidia. The appendages also were accidentally 

 omitted. They are very obscure and easily overlooked.

Stromata scattered, buried, erumpent through transverse cracks 

 in the bark, dark brown or black above, brownish inside, laterally 

 compressed so as to become lanceolate, not rising much above the 

 bark, of carnose-suberose consistence, 1-3 mm. long. Perithecia 4-10 

 in a stroma, irregularly crowded, globose, black, rather large | (mm.), 

 necks cylindrical, with their ostiola only slightly projecting through 

 the lance-shaped disk. Asci oblong-cylindrical, narrowed below, 8- 

 spored, 150-160 x 26-28 fi. Sporidia biseriate, oblong, ends broadly 

 rounded, 3-6-septate, with a large nucleus in each cell, not constricted 

 at the septa, brown, straight, 35-48 x 12|-15 fi. Paraphyses very
