  The 
  iEcidiacei 
  or 
  Cluster-cup 
  fungi 
  consist 
  essentially 
  of 
  small 
  

   cup-shaped 
  or 
  cylindrical 
  receptacles 
  which 
  contain 
  the 
  mostly 
  yellow 
  

   or 
  orange-colored 
  simple 
  spores. 
  These 
  cups 
  are 
  sometimes 
  scattered 
  

   over 
  the 
  leaves 
  but 
  they 
  are 
  more 
  frequently 
  clustered 
  together 
  on 
  

   discolored 
  spots. 
  

  

  In 
  Rmtelia 
  they 
  are 
  lacerated 
  and

  spores 
  brownish,

  In 
  ^Ecidium 
  the 
  cups 
  are 
  scolloped 
  or 
  toothed 
  on 
  the 
  margin. 
  

   In 
  Peridermium 
  they 
  rupture 
  irregularly
