 slightly constricted, with the lower cell a little narrower, and the peri-

Perithecia cespitose, ovoid, smooth, bright red, papilliform, about 

 200 (I diam., usually not collapsing, seated on a yellowish, slightly 

 erumpent stroma, which is often nearly obsolete. Asci subcylindrical.

 scarcely constricted, rather acutely elliptical, 12-15 x 4-5 p (12-16 x

Perithecia mostly cespitose, bright red, subovate, more or less 

 collapsing, small (200 jx diam.), seated mostly around the margin of 

 the small, pale, tuberculiform stroma, which, together with its group 

 of perithecia, is mostly less than 1 mm. diam. Asci cylindrical, 75 \ 

 8-10 p.. Sporidia uniseriate, narrow-elliptical, 14-16 x 6-7 ti. yellow- 

 ish-'subhy aline, becoming uniseptate. 



On bark of living alder, West Chester, Pa. (Everhart & Haines). 



Distinguished from ' N. coccinea by its broader, more obtuse, yel- 

 lowish sporidia and its more distinctly superficial stroma, which, in 

 some cases at least, seems to arise from the remains of dead scale 

 insects which are abundant on the bark. 



The above description is from the Pennsylvania specimens of 

 N. subcoccinea, S. & E., which are the same as the specimens of iV.
