Perithecia densely gregarious, superficial, depressed-globose, soon 

 collapsing to flat cup-shaped, coarsely wrinkled, Mack, without any 

 distinct ostiolnm, |-| mm. diam., seated on a scanty, black, pilose 

 -ubiculum. Asci clavate with a slender stipe, 8-spored, 40-45x8-9 //., 

 Sporidia lying irregularly in the asci, oblong or clavate-oblong, mostly 

 straight, 4-nucleate, hyaline, 9-1 1 x 2-2 1 fjt. 



On bark, Carolina (Schw.), also Carolina and Maine (Berkeley). 



The specimen in Herb. Schw., 141 3, labeled "Sphceria cupularis" 

 is this species, having the perithecia J-j mm. diam.. and asci shorter 

 and broader than in 'S. cupidaris. Whether this is the Spheeria 

 h'istis, Tode, is doubtful. Persoon gives S. tristis, Tode, interroga- 

 tively as a synonym of his S. tristis. Both speak of the thin, tomen- 

 tose subiculum, but Tode says the perithecia are so small as to be 

 scarcely visible, which certainly does not apply to the species here 

 described as Nitschkia tristis, (Pers.) 



The specimen in Fungi Gallici, 1485, labeled Sphceria tristis, 

 Tode, is (in our copy) only a patch of black tomeritum without any 

 perithecia. In the specc. issued by Cooke and Plowright the sporidia 

 are 7-9x2-2| /*, the contents often divided by a pseudoseptum across 

 the middle. 



Specc. on rotten maple from Ohio (Morgan, 976) have abundant, 

 narrow-elliptical, hyaline sporidia? 6-8 x 3 , but no asci, and may be 

 the spermogonial stage of this species.

Perithecia densely gregarious, about \ mm, diam., or a little less ? 

 spherical, minutely tubercular-roughened, soon collapsing. Asci cla- 

 vate. Sporidia elliptical, continuous, smoky-hyaline, or pale brown, 



6-8 x 3J-4J fi. 



On bark of dead trunks of Fraxinus, So. Carolina (Ravenel). 

 The perithecia are seated on a thin subiculum of creeping, septate 

 hvpha?. with which thev are also mostly fringed at base.
