 ranged m series, whitish, a long time covered by the elevated 

 epidermis; sporophores slender, erect, straight, crowded, 40-60 /« 

 long, T-2 // broad ; spores slender, curved, 5-6-nucleate, continu- 

 ous, hyaline, terminating at each end in a very thin bristle-like

Lower surface of leaves of Indian grass, Sorghastmm nutans 

 (L.) Nash. Stockton, Kansas. September. E. Bartholomew, 

 The species belongs to the subgenus Fiisa^nen. It is well marked 

 by the bristle-pointed spores, and is peculiar in having its recep- 

 tacles mostly arranged m lines and covered for a long time by the 



firm epidermis of the host plant
