Perithecia membranous, orbicular or discoid, 1-2 mm broad,

 to which it is adnate at the base, erumpent, black; spores com- 

 pact, ellipsoid or oblong, 16-24 ^^ong, ia-12 /a broad, supported 

 on more or less slender filiform hyaline sporophores. 



Dead branches of Ailanthus glandulosus Desf. 

 Stockton, Kansas. September.' E. Bartholomew. 



The perithecia are so imperfectly developed that the fungus 

 might easily be mistaken for a species of Melanconium. Hence the 

 specific name.
