by the thin, closely adhering epidermis, black, white within. Ostiola 

 perforated. Asci clavate, obtuse, 100-125 x 16-20 [x, with abundant, 

 conglutinated paraphyses. Sporidia crowded or biseriate, oblong or 

 subfusoid, straight or slightly curved, at first uniseptate, quadri- 

 nucleate, strongly constricted at the septum, finally 3-septate, hyaline, 

 30-40x10-12/^. 



On dead branches of Myrica Gale, lying partly in water, New 

 York State. 



The epidermis is so closely adherent that the perithecia appear as 

 if superficial or merely innate at the base. The nuclei of the sporidia 

 are large. Sporidia with 3 septa were rare, Ijut this may have been 

 due to immaturity.

Perithecia minute, black, covered by the epidermis which at 

 length ruptures in a stellate manner or irregularly. Asci? Sporidia 

 biseriate, colorless, constricted in the middle, 3-5-septate, 20-25 p. 

 long, the two parts formed by the central septum unequal in diameter.

Perithecia gregarious, pustuliform, entirely covered by the epi- 

 dermis which is usually not ruptured or blackened over them, sub- 

 prominent, of medium size. Asci cylindrical, 80-100 x 10-12 /i, 

 abruptly narrowed below into a short, stipe-like base, not paraphysate. 

 Sporidia uniseriate, elliptical, nearly hyaline, 3-septate, 12-18x7-8 //.

 N. J., and on Rihes, London, Canada (Dearness). 



This is certainly very near M. corticola, (Fckl.), but we have no 

 specc. of that species for comparison. It is also closely allied to Lep- 

 tosphceriafuscella, (B. & Br.), but that has olivaceous sporidia (see p. 

 353).
