Mycelium smoky-black, thin, composed of creeping, branching, 

 multiseptate, nucleate threads. Pycnidial perithecia brown-black, 

 setaceous, apices enlarged and subentire, 900x35//, containing hyaline, 

 uniseptate, oval or elliptical sporules 10-1 2 x 2 //. Ascigerous peri- 

 thecia brown-black, globose, at length depressed-sublentifbrm, (120 p), 

 with 10-12 straight, brown appendages, 100-120x4 /i. Asci sub- 

 clavate, 8-spored, 75-120x15-20 [i. Sporidia hyaline, clavate-cylin- 

 drical or fusoid-oblong, 4-5-nucleate and more or less constricted 

 between the nuclei, at length distinctly 4-5-septate, 30-45 x 6-7 u, 

 lying in 3 or 4 series in the asci. 



On leaves of Gelsemium sempervirens and Myrica, Florida 

 (Martin). Whether the subulate, pycnidial perithecia belong to this 

 is uncertain. 



B. Asci unknown; sporidia vnuriform.
