  The 
  plant 
  is 
  widely 
  distributed 
  ou 
  both 
  Continents, 
  and 
  occurs 
  

   also 
  on 
  the 
  birch, 
  maple, 
  and 
  other 
  deciduous 
  trees.

  Character 
  and 
  distribution. 
  — 
  Another 
  wood 
  destroying 
  fungus 
  

   shaped 
  something 
  like 
  a 
  horse's 
  hoof, 
  but 
  much 
  more 
  irregular, 
  

   is 
  the 
  Trametes 
  pini 
  shown 
  in 
  plate 
  60. 
  This 
  photograph 
  is 
  

   taken 
  from 
  a 
  specimen 
  on 
  a 
  pine 
  log 
  collected 
  by 
  Professor 
  

   Harris 
  near 
  Mansfield, 
  lyouisiana, 
  during 
  the 
  winter 
  of 
  1898-99. 
  

   The 
  fruiting 
  surface 
  here 
  is 
  also 
  honey-combed, 
  but 
  there 
  are 
  

   other 
  characters 
  which 
  place 
  it 
  in 
  the 
  genus 
  Trametes, 
  instead 
  of 
  

   in 
  Polyporus 
  or 
  Fomes. 
  This 
  plant 
  is 
  also 
  perennial 
  and 
  each 
  

   consecutive 
  ring 
  represents 
  a 
  yearly 
  layer 
  added 
  by 
  growth, 
  the 
  

   lowermost 
  layer 
  being 
  that 
  of 
  the 
  last 
  year's 
  growth. 
  This 
  fun- 
  

   gus 
  occurs 
  on 
  pines 
  in 
  Europe, 
  and 
  also 
  in 
  the 
  southern 
  and 
  

   southwestern 
  United 
  States. 
  In 
  Europe 
  it 
  is 
  known 
  to 
  produce 
  

   a 
  characteristic 
  and 
  serious 
  disease 
  of 
  the 
  timber 
  pines.

  Characters 
  . 
  — 
  Another 
  very 
  interesting 
  fungus 
  is 
  that 
  shown 
  

   in 
  Plates 
  61 
  and 
  62. 
  It 
  is 
  the 
  Dcedalea 
  ambigua, 
  also 
  

   sometimes 
  called 
  the 
  Trametes 
  ambigua. 
  The 
  honey-combed 
  

   fruiting 
  surface 
  here 
  is 
  very 
  irregular, 
  sometimes 
  the 
  tubes 
  or 
  

   pores 
  are 
  cylindrical 
  with 
  rounded 
  mouths, 
  and 
  again 
  they 
  repre- 
  

   sent 
  elongated 
  or 
  sinuous 
  passages, 
  the 
  round 
  ones 
  illustrating 
  

   Trametes 
  while 
  the 
  elongated 
  or 
  sinuous 
  ones 
  xW.ws'vcdX^ 
  Dcedalea 
  . 
  

   Since 
  the 
  plant 
  in 
  this 
  character 
  varies 
  from 
  one 
  to 
  the 
  other, 
  it 
  

   is 
  rather 
  " 
  ambiguous 
  " 
  as 
  to 
  which 
  genus 
  it 
  appertains, 
  and 
  so 
  

   it 
  was 
  named 
  Dcedalea 
  ambigua. 
  This 
  plant 
  was 
  also 
  collected 
  

   by 
  Professor 
  Harris 
  in 
  Louisiana. 
  

  

  It 
  is 
  whitish 
  in 
  color, 
  of 
  a 
  very 
  beautiful 
  appearance, 
  grows 
  

   on 
  several 
  different 
  deciduous 
  trees, 
  and 
  forms 
  a 
  true 
  single 
  

   shelf. 
  An 
  individual 
  illustrated 
  in 
  Plate 
  61, 
  is 
  an 
  abnormal 
  

   form 
  and 
  shows 
  to 
  us 
  one 
  very 
  interesting 
  peculiarity 
  of 
  all 
  the.se 
  

   plants. 
  The 
  figure 
  to 
  the 
  left 
  represents 
  the 
  position 
  in 
  

   which 
  the 
  fungus 
  grew 
  when 
  the 
  tree 
  to 
  which 
  it 
  was 
  attached 
  

   was 
  standing. 
  At 
  this 
  time 
  the 
  broad 
  single 
  shelf 
  was 
  formed 
  

   so 
  that 
  the 
  shelf 
  was 
  horizontal, 
  or 
  parallel 
  with 
  the 
  surface 
  of 
  

   the 
  earth. 
  This 
  is 
  a 
  peculiarity 
  of 
  all 
  the 
  bracket 
  fungi, 
  and 
  of
