  Nothing 
  stimulates 
  the 
  study 
  of 
  a 
  group 
  of 
  plants 
  more 
  than 
  a 
  good 
  

   synopsis 
  of 
  the 
  species. 
  This 
  is 
  especially 
  desirable 
  when 
  the 
  group 
  is 
  

   absolutely 
  unapproachable, 
  except 
  by 
  the 
  trained 
  specialist. 
  The 
  my- 
  

   cologists 
  are 
  rapidly 
  arousing 
  interest 
  in 
  their 
  department 
  by 
  the 
  prepa- 
  

   ration 
  of 
  just 
  such 
  monographs 
  as 
  the 
  one 
  before 
  us.

  fleshy 
  and 
  perishable 
  that 
  

   the 
  natural 
  form 
  and 
  coloration 
  have, 
  to 
  a 
  large 
  extent, 
  disappeared. 
  

   Professor 
  Peck 
  deserves 
  the 
  thanks 
  of 
  mycologists 
  for 
  thus 
  seeking 
  to 
  

   facilitate 
  the 
  study 
  of 
  a 
  group 
  difficult, 
  not 
  only 
  in 
  the 
  imperfection 
  of 
  

   Its 
  preservation, 
  but 
  also 
  in 
  the 
  widely 
  scattered 
  publication 
  of 
  our 
  Amer- 
  

   ican 
  species. 
  The 
  Hymenomycetes 
  Europa^i 
  contains 
  100 
  species 
  while 
  this 
  

   paper 
  presents 
  110, 
  36 
  of 
  which 
  occur 
  also 
  in 
  Europe. 
  This 
  large 
  number 
  

   of 
  endemic 
  species 
  indicates 
  that 
  the 
  United 
  States 
  is 
  rich 
  and 
  peculiar 
  in 
  

   Its 
  Boleti. 
  The 
  three 
  genera 
  are 
  Boletinus, 
  Boletus 
  and 
  Strobilomyces, 
  

   conUimng 
  5 
  103 
  and 
  2

  respectively: 
  The 
  large 
  genus 
  Boletus 
  is 
  

   d 
  vided 
  into 
  15 
  tribes, 
  and

  the 
  103
