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

 (nearly sulphur yellow), with a papillose ostiolum, 125-165 /j. 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)x2J-3J p. sporidia, distinctly constricted at the sep- 

 tum, ends rounded or obtusrly pointed.

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

 contracted base, covered with a sulphur-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 /JL. Sporidia subbiseriate, allantoid, 

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

 Differs from JV. aiirea, S. c\: S.. in its smaller Sporidia.
