  The 
  cells 
  of 
  the 
  spores 
  are 
  often 
  nucleate, 
  and 
  the 
  terminal 
  cell 
  is 
  

   sometimes 
  truncate 
  and 
  paler 
  than 
  the 
  others. 
  The 
  uncinate 
  base 
  of 
  

   the 
  pedicel 
  is 
  a 
  characteristic 
  feature.

  This 
  plant 
  was 
  formerly 
  reported 
  as 
  a 
  variety 
  of 
  Phragmidium 
  

   mucronatum, 
  but 
  having 
  compared 
  it 
  with 
  authenticated 
  European 
  

   specimens 
  of 
  both 
  forms 
  of 
  that 
  species, 
  I 
  am 
  satisfied 
  that 
  our 
  plant 
  

   is 
  distinct. 
  In 
  the 
  Uredo 
  form 
  the 
  spots 
  are 
  more 
  definite, 
  the 
  sori 
  

   and 
  spores 
  are 
  larger 
  and 
  the 
  latter 
  have 
  a 
  more 
  coarsely-roughened 
  

   epispore. 
  In 
  the 
  Brand 
  form 
  the 
  spores 
  are 
  longer 
  and 
  yet 
  more 
  

   narrow, 
  the 
  papillae 
  are 
  more 
  prominent 
  and 
  the 
  mucro 
  is 
  generally 
  

   longer 
  and 
  roughened.
