Perithecia gregarious, superficial, spherical, becoming concave l)y 

 collapsing, subpapillate, reddish-orange, fading at length, subpilose at 

 base, soft, about \ mm. diam. Asci very shortly pedicellate, cylin- 

 drical or clavate-cylindrical, 80-90 x 8-10 (i, when young, subcristate

N. sulphurea, Ell. & Calkins. Journ. Mycol. IV, p. 57. 



Scattered on a thin farinose-tomentose, yellow subiculum extend- 

 ing for a centimeter or more. Perithecia ovate-conical, pruinose, yellow 

 (nearly sulphur yellow), with a papillose ostiolum, 125-165 // diam. 

 In the specimens thus far seen, the asci had disappeared, but there 

 was an abundance of oblong or clavate-oblong, hyaline, uniseptate, 

 7-12 (mostly 8-9) x 2|-3| ^i sporidia, distinctly constricted at the sep- 

 tum, ends rounded or obtusely pointed.

N. sulphurkta, E. & E. Proc. Phil. Acad. July, 1890, p. 248. 



Perithecia gregarious, minute (200 //), subglobose with a slightly 

 contracted base, covered with a sulphui'-yellow, granulose-pruinose 

 coat which finally disappears and leaves the perithecia black; col- 

 lapsed above when dry and more or less distinctly radiate-sulcate. 

 Asci subcylindrical, 65-70x6-7 fi. Sporidia subbiseriate, allantoid, 

 hyaline, with a small nucleus near each end, slightly curved, 7-12x2 ix. 

 Differs from N. aurea, S. & S., in its smaller sporidia.
