  Woods 
  and 
  copses. 
  Rensselaer, 
  Saratoga 
  and 
  Fulton 
  counties. 
  

  

  This 
  is 
  a 
  very 
  distinct 
  and 
  beautiful 
  species. 
  Mr. 
  Ravenel 
  remarks 
  

   in 
  his 
  notes 
  that 
  " 
  this 
  plant 
  is 
  not 
  infested 
  by 
  larvae, 
  and 
  preserves 
  

   more 
  constant 
  characters 
  than 
  any 
  other 
  Boletus 
  with 
  which 
  I 
  am 
  

   acquainted." 
  The 
  webby 
  powdered 
  filaments 
  constitute 
  a 
  universal 
  

   veil, 
  which 
  at 
  first 
  covers 
  the 
  whole 
  plant 
  and 
  conceals 
  the 
  young 
  

   tubes. 
  As 
  the 
  pileus 
  expands, 
  the 
  veil 
  generally 
  disappears 
  from 
  the 
  

   disk 
  and 
  ruptures 
  between 
  the 
  margin 
  and 
  the 
  stem, 
  a 
  part 
  adhering 
  

   to 
  each. 
  In 
  consequence 
  of 
  the 
  peculiar 
  veil 
  and 
  the 
  slight 
  viscidity 
  

   of 
  the 
  pileus 
  the 
  species 
  does 
  not 
  harmonize 
  well 
  with 
  the 
  associated 
  

   species, 
  and 
  but 
  for 
  the 
  slight 
  annulus 
  it 
  might 
  as 
  well 
  be 
  placed 
  near 
  

   B. 
  piperatus. 
  The 
  annulus 
  is 
  sometimes 
  stained 
  by 
  the 
  spores. 
  

   These, 
  when 
  caught 
  on 
  white 
  paper, 
  at 
  first 
  appear 
  to 
  have 
  a 
  slight 
  

   greenish 
  tint. 
  

  

  Boletus 
  spectabilis 
  Pk. 
  

   Showy 
  Boletus. 
  

  

  Pileus 
  broadly 
  convex, 
  at 
  first 
  covered 
  with 
  a 
  red 
  tomentum, 
  then 
  

   squamose, 
  viscid 
  when 
  moist, 
  red, 
  the 
  tomentose 
  scales 
  becoming 
  

   grayish-red, 
  brownish 
  or 
  yellowish, 
  flesh 
  whitish 
  or 
  pale-yellow 
  ; 
  tubes
