Sphenolobus hellerianus (Nees) Steph. 

 Decaying wuud. Akaniont, Albany co. May. 



Sporodesmium pluriseptatum (K. & H.) Pk. 



Rind of sununer crookncck s(][uash, Cucurbita pepo L. 

 Menands, Albany co. September. 



This is Sporodesmium m u c o s u m var. p 1 u r i s e p - 

 t a t u m Karst. & Kar. but it differs so decidedly from S . 

 mucosuni that it is far more satisfactory to give it specific 

 rank than varietal. The spores in our specimens exceed in size 

 and in the number of septa the spores of the typical variety even 

 and therefore intensify the difference between it and S. mu co- 

 sum . In our specimens they are 40-80 !>■ long and 3-8-septate 

 with usually more than two longitudinal septa. The fungus forms 

 black velvety patches y^. to 3^ inch in diameter.
