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

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

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

Perithecia gregarious, minute (200 p\ subglobose with a slightly 

 contracted base, covered with a sulphur-yellow, granulose-pruinoee 

 coat which finally disappears and leaves the perithecia Mack: col- 

 lapsed above when dry and more or less distinctly radiatc-sulcatc. 

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

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