A NEW UROMYCES. 
BY BYRON D. HALSTED, AMES, IOWA. 
The following are the characteristic features of a species of Uromyces 
found near Ames, Iowa, upon leaves of Leersia Virgimca, Willd.: 
Uromyces digitatus, Halsted.—Sori mostly hypogenous, small, 
elongated, forming irregular rows ; uredospores 22 - 25 x 26—30 /q ellip¬ 
tical, light yellow, indistinctly echinulate, tips dark; teleutosori shining 
black, spores wedge-shaped and quite irregular, 17—30 x2>—33 pedicel 
about one-half the length of spore. The broad, free end of the spore is 
divided into 5—20 sharp or blunt projections, the longer with hyaline tips. 
This Uromyces approaches XJ. acumi7iatus, Arth., but differs from it 
greatly in the wedge or triangular shape of che tePuto-spore and the large 
number of blunt terminations which cover the broad, free end. These 
irregular projections make the spore look in shape like a boxing glove ; 
they frequently extend downward along the whole of one side of the 
spore. __
