﻿J2 
  Sixteenth 
  Annual 
  Report 
  of 
  the 
  

  

  call 
  it 
  for 
  the 
  present 
  Cryptosporium 
  macrospermum 
  N. 
  sp., 
  in 
  al- 
  

   lusion 
  to 
  this 
  character. 
  They 
  are 
  fusiform, 
  curved 
  and 
  generally 
  

   terminate 
  at 
  each 
  end 
  in 
  a 
  very 
  acute 
  or 
  subulate 
  point, 
  though 
  

   sometimes 
  one 
  end 
  is 
  less 
  sharply 
  pointed 
  than 
  the 
  other. 
  The 
  

   length 
  of 
  the 
  spore 
  is 
  60-80 
  mm. 
  Its 
  breadth 
  in 
  the 
  widest 
  part 
  

   is 
  5-6 
  mm. 
  

  

  Inasmuch 
  as 
  I 
  find 
  the 
  fungus 
  threads 
  or 
  mycelium 
  in 
  the 
  bark, 
  

   both 
  near 
  to 
  and 
  remote 
  from 
  the 
  pustules 
  my 
  impression 
  is 
  that 
  

   the 
  disease 
  in 
  the 
  balsam 
  fir 
  at 
  least 
  is 
  caused 
  by 
  the 
  fungus. 
  In 
  

   the 
  spruce 
  I 
  have 
  not 
  yet 
  been 
  able 
  to 
  find 
  pustules 
  of 
  the 
  fungus, 
  

   nor 
  even 
  its 
  mycelium 
  in 
  the 
  dead 
  bark. 
  This 
  casts 
  a 
  doubt 
  upon 
  

   the 
  identity 
  of 
  the 
  disease 
  in 
  the 
  two 
  trees, 
  or 
  upon 
  the 
  correctness 
  

   of 
  the 
  theory 
  that 
  the 
  fungus 
  is 
  the 
  cause 
  of 
  the 
  disease 
  in 
  the 
  

   balsam. 
  

  

  Probably 
  the 
  quickest 
  and 
  most 
  satisfactory 
  way 
  to 
  settle 
  the 
  

   question 
  would 
  be 
  by 
  experiment. 
  The 
  inoculation 
  of 
  young 
  and 
  

   healthy 
  trees 
  both 
  of 
  balsam, 
  fir 
  and 
  spruce 
  with 
  the 
  spores 
  of 
  this 
  

   fungus 
  ought 
  to 
  show 
  whether 
  it 
  is 
  the 
  cause 
  of 
  the 
  disease 
  or 
  

   merely 
  a 
  consequence." 
  

  

  This 
  disease 
  has 
  also 
  been 
  studied 
  by 
  Dr. 
  Perley 
  Spaulding 
  of 
  

   the 
  Bureau 
  of 
  Plant 
  Industry, 
  U. 
  S. 
  Department 
  of 
  Agriculture, 
  

   and 
  various 
  inoculations 
  have 
  been 
  made, 
  but 
  no 
  results 
  yet 
  

   obtained.
