  The 
  species 
  is 
  closely 
  related 
  to 
  B. 
  granidatus, 
  from 
  which 
  it 
  differs 
  

   especially 
  in 
  its 
  copious 
  gluten, 
  darker-colored 
  pileus, 
  shorter 
  stem, 
  

   and 
  in 
  the 
  almost 
  entire 
  absence 
  of 
  granules 
  from 
  the 
  tubes 
  and 
  

   stem. 
  When 
  present 
  they 
  are 
  limited 
  to 
  the 
  upper 
  part 
  of 
  the 
  stem 
  

   and 
  are 
  extremely 
  minute 
  and 
  inconspicuous. 
  It 
  occurs 
  very 
  late 
  in 
  

   the 
  season. 
  B. 
  viscosus

  Pileus 
  convex, 
  even, 
  soft, 
  viscid 
  or 
  glutinous 
  when 
  moist, 
  some- 
  

   what 
  shining 
  when 
  dry, 
  tawny 
  or 
  chestnut 
  color, 
  flesh 
  whitish 
  tinged 
  

   with 
  yellow, 
  bluish 
  next 
  the 
  tubes 
  ; 
  tubes 
  rather 
  long 
  and 
  large, 
  

   angular, 
  adnate, 
  sinuate-depressed, 
  whitish-yellow, 
  becoming 
  tinged 
  

   with 
  green 
  ; 
  stem 
  nearly 
  equal, 
  rather 
  long, 
  even, 
  paler 
  than 
  the 
  

   pileus, 
  brownish-pruinose 
  ;

  The 
  dimensions 
  of 
  the 
  spores 
  are 
  derived 
  from 
  the 
  American 
  plant. 
  

   They 
  are 
  smaller 
  than 
  those 
  given 
  by 
  Karsten 
  for 
  the 
  European 
  

   plant. 
  We 
  have 
  observed 
  no 
  greenish 
  hue 
  to 
  the 
  tubes 
  nor 
  bluish 
  

   color 
  to 
  the 
  flesh, 
  and 
  to 
  this 
  extent 
  our 
  specimens 
  are 
  doubtful. 
  

   The 
  plant 
  needs 
  further 
  examination. 
  

  

  Boletus 
  piperatus 
  Bull. 
  

   Peppery 
  Boletus. 
  

  

  Pileus 
  convex 
  or 
  nearly 
  plane, 
  smooth, 
  slightly 
  viscid 
  when 
  moist, 
  

   yellowish, 
  cinnamon 
  or 
  sub 
  ferruginous, 
  flesh 
  white 
  or 
  yellowish, 
  taste 
  

   acrid, 
  peppery 
  ; 
  tubes 
  rather 
  long 
  and 
  large, 
  angular, 
  plane 
  or 
  con- 
  

   vex, 
  adnate 
  or 
  subdecurrent, 
  reddish-ferruginous, 
  generally 
  more 
  

   highly 
  colored 
  than 
  the 
  pileus 
  : 
  stem 
  slender, 
  nearly 
  equal, 
  tawny- 
  

   yellow, 
  bright 
  -yellow 
  at 
  the 
  base 
  ; 
  spores 
  ferruginous-broivn, 
  sub 
  fusi- 
  

   form, 
  .00035 
  to 
  .00045

  stem

  to

  Woods 
  and 
  open 
  places. 
  Common 
  and 
  variable. 
  July 
  to 
  October. 
  

  

  The 
  species 
  is 
  readily 
  known 
  by 
  the 
  peppery 
  taste 
  of 
  the 
  flesh, 
  and 
  

   the 
  bright 
  yellow 
  color 
  of 
  the 
  base 
  of 
  the 
  stem. 
  The 
  pileus 
  is 
  some- 
  

   times 
  rimose-scaly 
  or 
  rimose-areolate. 
  It 
  is 
  less 
  viscid 
  than 
  most 
  other 
  

   species 
  of 
  this 
  section. 
  The 
  color 
  of 
  the 
  spores 
  is 
  similar 
  to 
  that 
  

   of 
  the 
  spores 
  of 
  11. 
  Elbensis. 
  B. 
  ferruginatua
