  Sometimes 
  the 
  spots 
  are 
  angular, 
  being 
  limited 
  by 
  the 
  veinlets 
  of 
  

   the 
  leaf. 
  In 
  this 
  species 
  and 
  in 
  the 
  next 
  one 
  I 
  have 
  not 
  seen 
  the 
  

   spores 
  septate, 
  but 
  suspecting 
  that 
  the 
  nuclei 
  indicate 
  septa 
  in 
  more 
  

   mature 
  specimens, 
  I 
  have 
  referred 
  the 
  species 
  to 
  this 
  genus 
  for 
  the 
  

   present. 
  They 
  may 
  belong 
  rather 
  to 
  Cylindrium 
  or 
  Fusidium. 
  

  

  Ramularia 
  angustata. 
  

  

  Spots 
  small, 
  orbicular, 
  sometimes 
  confluent, 
  pale 
  greenish-yellow, 
  

   becoming 
  reddish-brown 
  or 
  browu, 
  frosted 
  on 
  the 
  lower 
  surface 
  by 
  

   the 
  fungus 
  ; 
  flocci 
  minute 
  ; 
  spores 
  narrowly 
  fusiform 
  or 
  subcylindrical, 
  

   .0003 
  to 
  .0004 
  in. 
  long, 
  about 
  .0001 
  in.

  often 
  containing 
  two 
  

   or 
  three 
  nucleoli.

  The 
  very 
  narrow 
  spores 
  suggest 
  the 
  specific 
  name. 
  

  

  Ramularia 
  lineola. 
  

  

  Spots 
  suborbicular, 
  sometimes 
  confluent, 
  brown, 
  concentrically 
  

   lineolate 
  ; 
  flocci 
  obscure, 
  tufted, 
  hypophyllous 
  ; 
  spores 
  slender, 
  

   cylindrical, 
  obtuse, 
  .0005 
  to 
  .0008 
  in. 
  long, 
  often 
  uniseptate. 
  

  

  Living

   July. 
  

  

  The 
  fungus 
  is 
  so 
  minute 
  that 
  it 
  is 
  scarcely 
  visible 
  to 
  the 
  naked 
  eye. 
  

  

  Sporotrichum 
  larvicolum. 
  

  

  Flocci 
  slender, 
  simple 
  or 
  branched, 
  forming 
  a 
  continuous, 
  dense, 
  

   soft, 
  white 
  or 
  yellowish 
  stratum 
  coating 
  the 
  whole 
  matrix 
  ; 
  spores 
  

   abundant, 
  minute, 
  globose, 
  .00008 
  to 
  .00012 
  in. 
  broad.

  July. 
  

  

  The 
  larvae 
  were 
  very 
  numerous 
  and, 
  but 
  for 
  the 
  check 
  imposed 
  

   upon 
  the 
  increase 
  of 
  the 
  species 
  by 
  the 
  attacks 
  of 
  this 
  fungus, 
  they 
  

   would 
  probably 
  in 
  a 
  short 
  time 
  have 
  completely 
  defoliated 
  all 
  the 
  

   alders 
  in 
  that 
  locality. 
  In 
  some 
  specimens 
  the 
  fungus 
  spores 
  were 
  so 
  

   abundant 
  that 
  the 
  surface 
  of 
  the 
  stratum 
  had 
  a 
  pulverulent 
  appearance.
