X. perforata, E1L & Holvv. in Geol. and Nat. Hist. Survey of 

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



Perithecia gregarious and subconfluent, 150-200 /JL diam., rough 

 |>ruinose-furfiiraceous, 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 /./, with- 

 out paraphyses. Sporidia obliquely imiseriate, elliptical or subovate. 

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

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

 cifically distinct.

trees. Saccardo properly observes that this scarcely differs from J\ T . 

 episphceria, Fr., except in its ovoid, scarcely collapsing perithccia and 

 its less distinctly septate sporidia.

Perithecia gregarious, minute (125-150 /j), 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, 35x5 /jt. Spo- 

 ridia biseriate, oblong-fusiform, subhyaline, uniseptate and slightly con- 

 stricted around the middle, 11-13x2^-3 //.
