Perithecia gregarious, membranaceous, depressed-spherical, soon 

 collapsing to cup-shaped, .'>">0-4UO p. diam., smooth above, seated on a 

 thin, black or olivaceous-black subiculum of interwoven, septate hyplne. 

 Asci oblong-clavate, sessile, 80-112x20-25 /JL. Sporidia biseriate, 

 clavate-fusoid, hyaline, 5-7-septate, nearly straight, 30-40 x 5-7 /j. (Ex- 

 ceptionally 8-10 /JL thick). 



On decaying wood and bark, Carolina, New Jersey, Ohio and 

 Missouri. 



Cooke, in his Synopsis, places this among the brown-spored species, 

 but we have ahvays found the sporidia hyaline.

Perithecia spherical or pear-shaped, carbonaceous, more or less

 subiculum of brown, septate hyphae. Sporidia mostly fusoid or fnsoid-

Perithecia crowded, often in patches of considerable extent, spher- 

 ical or pear-shaped, black, rough, with a broad, wrinkled ostiolum, 

 bare above, but sending out around the base abundant, stiff, straight, 

 dark brown hairs, which also form a tangled, bristly subiculuni. Asci 

 sliirhtlv clavate-thickened above and a little narrowed below, sessile.

8-spored, 95-108 // long, 16-21 t u thick. Sporidia biseriate, short-

 curved, 28-38x8-9 ft ; paraphyses filiform. 



On rotten elm wood, Carolina and Missouri.
