Perithecia densely cespitose, bright red, becoming darker, rough, 

 with a papilliform ostiolum, seated on a pulvinate, tuberculiform, 

 fleshy stroma (Tubercularia vulgaris Tode). Asci clavate-cylindrical, 

 subattenuated above, 70-90 x 8-11 p. Sporidia subbiseriate, oblong, 

 obtuse at the ends, straight or slightly curved, uniseptate, hyaline, 

 mostly 12-15x5-7 p. 



On dead limbs of almost every kind of deciduous trees, common 

 and variable.

Cespitose on a tubercular base {Tubercularia Sambuci, Cda.) 

 Perithecia 4-12 on a stroma, ovate-globose, pruinose, pale red, about 

 J mm. diam., strongly collapsed above when dry. Ostiolum papilli- 

 form, finely fimbriate. Asci oblong-clavate, 50-60 x 6-7 p (p. sp.), 

 without paraphyses. Sporidia biseriate, oblong, uniseptate, straight 

 or slightly curved, hyaline, 12-20 x 3-4| p. The Tubercularia has 

 allantoid, hyaline conidia 6-8 x l|-2 p, on basidia 35-40 p long, 

 branched above. This is, according to the specimens in De Thiimen's 

 Mycotheca and in Roumeguere's Fungi Gallici, the T. Sambuci, Cda. 



On Sambucus Canadensis, Lincoln, Nebraska (Webber) 



Possibly a var. of N. cinnabarina. 



N. pithoides, E. & E. Proc. Phil. Acad. July, 1890, p. 247. 



Densely cespitose, forming suborbicular tufts 1 J 2J mm. diam. 

 Perithecia ovate, dark red, about 200 p diam.., muriculate-roughened, 

 collapsing above so as to appear slightly truncate and slightly concave, 

 appearing in profile like small jars. Ostiolum papilliform, only 

 slightly prominent. Asci cylindrical, 75-80x5 p. Paraphyses not 

 seen. Sporidia uniseriate, oblong-elliptical, 2-nucleate, becoming 

 uniseptate, 6-10 x 3-3 \ p, smoky -hyaline. The perithecia are seated 

 on a convex, yellow stroma, 50-100 together, and when young are 

 clothed with a few short, white, glandular hairs. Nearly allied to 

 N. microspora, C. & E. which has less numerous, paler red, smoother, 

 more irregularly collapsed perithecia. The specific name from Greek 

 pithos a barrel. 



On dead alders, British Columbia, May, 1889 (Macoun, 122).

" Cespitose, red, inclining to brown. Ostiolum papilliform, at 

 length sunk from collapsing. Sporidia cymbiform, uniseptate, 15-20 p 

 long. On elm, New England, Russell)." Var. Magnolim, Sacc.
