perfectly paraphysate. Sporidia biseriate, oblong-elliptical, 2-nucleate, 

 becoming uniseptate, 8-12 x 3-4 ;z, hyaline. The asci are contracted 

 at the apex into a short truncate apiculus.

 Minn., Bull. No. 3, p. 33. 



Perithecia gregai-ious and subconfluent, 150-200 n diam., rough 

 pruinose-furfuraceous, pale at first, becoming orange-red, depressed- 

 globose, ostiolum papilliform and collapsing when dry, so as to appear 

 broadly perforated above. Asci clavate-cylindrical, 75 x 7-8 n, with- 

 out paraphyses. Sporidia obliquely uniseriate, elliptical or subovate, 

 uniseptate, hyaline or with a faint tinge of rose-color, 8-12x5-6 fi. 

 This comes very near N. vulpina, Cke., and possibly may not be spe- 

 cifically distinct.

Perithecia scattered, adnate, ovoid, rarely subsphseroid, smooth, 

 blood-red, rarely JJesh-color, soft, about 180^ diam. Ostiolum papil- 

 liform. Asci cylindrical, 50-60 x 5-6 ji, 8-spored. Sporidia obliquely 

 uniseriate, elliptical or subelliptical, unequally uniseptate, slightly con- 

 stricted, hyaline or with a slight tinge of rose-color, 7-10 x 4-5 n- 



Common on moist, decaying wood and bark of various dpciduous 

 trees. Saccardo properly observes that this scarcely differs from N. 

 episphmria, Fr., except in its ovoid, scarcely collapsing perithecia and 

 its less distinctly septate sporidia.

Exsicc. Ell. N, A. F. 1332. 



Perithecia gregarious, minute (125-150 fi), flesh-colored, subglo- 

 bose or ovate, the apex flattened into a circular, granular-roughened 

 disc, with the edges slightly projecting. Ostiolum in the center of the 

 disc, minute, papilliform, brown. Asci sublanceolate, 35 x 5 /i. Spo- 

 I'idia biseriate, oblong-fusiform, subhyaline, uniseptate and slightly con- 

 stricted around the middle, 11-13 x2|-3 fi. 



On the inside of white cedar bark, stripped from the living tree 

 and left lying on the ground, Newfield, N. J., Sept., 1882.
