Perithecia gregarious, membranaceous, depressed-spherical, soon 

 collapsing to cup-shaped, 350-400 p diam., smooth above, seated on a 

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

 Asci oblong-clavate, sessile, 8011 2 x 20-25 p. Sporidia biseriate, 

 clavate-fusoid, hyaline, 5-7 -septate, nearly straight, 30-40 x 5-7 p (ex- 

 ceptionally 8-10 p 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 always found the sporidia hyaline.

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

 hairy, seated on and surrounded by a more or less dense, felt-like 

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

 oblong, 2- or more-septate, brown or w T ith the terminal cells hyaline.

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 subiculum. Asci 

 slightly clavate-thickened above and a little narrowed below, sessile, 

 8-spored, 95-108 p long, 16-21 p thick. Sporidia biseriate, short- 

 cylindrical, rounded at the ends, 3-septate, the two middle cells brown 

 and longer, and the two terminal cells hyaline, shorter and more or less 

 curved, 28-38x8-9 p\ paraphyses filiform. 



On rotten elm wood, Carolina and Missouri. 



Var. phceostromoides, (Pk.), (Sphceria phwostromoides, Pk. 

 28th Rep. p. 77, t. II, fig. 30-35) is said to differ in its shorter (25 p 

 long) sporidia and uniseptate conidia. Specimens from Missouri (De-
