  The 
  smoothish-stemmed 
  Boletus 
  is 
  well 
  marked 
  by 
  its 
  cylindric 
  

   minutely 
  scurfy 
  stem 
  which 
  is 
  colored 
  like 
  the 
  tubes. 
  Its 
  cap 
  is 
  

   smooth 
  and 
  nearly 
  always 
  some 
  shade 
  of 
  red 
  or 
  bay. 
  Specimens 
  

   occur 
  occasionally 
  in 
  which 
  it 
  approaches 
  grayish 
  brown 
  or 
  wood- 
  

   brown. 
  The 
  flesh 
  is 
  white 
  and 
  unchangeable 
  when 
  cut 
  or 
  broken. 
  

  

  The 
  tubes 
  at 
  first 
  have 
  a 
  nearly 
  plane 
  surface 
  but 
  this 
  becomes 
  

   somewhat 
  convex 
  with 
  age, 
  and 
  slightly 
  depressed 
  around 
  the 
  stem. 
  

   The 
  tube 
  mouths 
  are 
  small 
  and 
  nearly 
  round. 
  The 
  color 
  of 
  the 
  

   tubes 
  is 
  at 
  first 
  a 
  beautiful 
  pale 
  yellow 
  but 
  it 
  becomes 
  darker 
  or 
  

   slightly 
  greenish 
  yellow 
  with 
  age. 
  

  

  The 
  stem 
  is 
  colored 
  very 
  nearly 
  like 
  the 
  tubes, 
  but 
  sometimes 
  it 
  

   has 
  a 
  slight 
  reddish 
  tint 
  toward 
  the 
  base^. 
  Its 
  peculiar 
  feature 
  con- 
  

   sists 
  of 
  the 
  minute 
  branny 
  particles 
  upon 
  it. 
  They 
  are 
  so 
  small 
  and 
  

   pale 
  that 
  they 
  are 
  easily 
  overlooked. 
  

  

  There 
  is 
  a 
  variety 
  in 
  which 
  the 
  cap 
  is 
  corrugated 
  or 
  irregularly 
  

   pitted 
  anl 
  wrinkled. 
  Its 
  name 
  is 
  Boletus 
  subglabj'ipes 
  corrugis 
  Pk. 
  

  

  The 
  cap 
  is 
  i-| 
  to 
  4 
  in. 
  broad, 
  the 
  stem 
  is 
  2 
  to 
  3 
  in. 
  long 
  and 
  

   4 
  to 
  8 
  lines 
  thick. 
  The 
  plants 
  are 
  found 
  in 
  woods 
  in 
  July 
  and 
  

   August.

  Plate

  Pileus 
  fleshy, 
  convex, 
  glabrous, 
  grayish 
  red, 
  bay 
  red 
  or 
  chestnut 
  

   color, 
  flesh 
  white, 
  unchangeable; 
  tubes 
  at 
  first 
  concave 
  or 
  nearly 
  

   plane, 
  white 
  and 
  stuffed, 
  then 
  convex, 
  slightly 
  depressed 
  around 
  the 
  

   stem, 
  ochraceous 
  yellow; 
  stem 
  mostly 
  obclavate 
  and 
  reticulate 
  to 
  the 
  

   base; 
  spores 
  oblong-fusiform, 
  .0005 
  to 
  .0006 
  in. 
  long, 
  .00016 
  to 
  

   .0002 
  broad. 
  

  

  The 
  club-stemmed 
  Boletus 
  is 
  so 
  closely 
  related 
  to 
  the 
  edible 
  

   Boletus 
  and 
  so 
  closely 
  connected 
  by 
  intermediate 
  forms 
  that 
  it 
  seems 
  

   to 
  be 
  only 
  a 
  variety 
  of 
  it, 
  but 
  one 
  worthy 
  of 
  illustration. 
  It 
  differs 
  

   in 
  the 
  more 
  uniform 
  color 
  of 
  the 
  cap, 
  in 
  having 
  the 
  tubes 
  less 
  de- 
  

   pressed 
  around 
  the 
  stem 
  and 
  less 
  tinted 
  with 
  green 
  when 
  mature 
  and 
  

   in 
  having 
  the 
  stem 
  more 
  club-shape 
  and 
  commonly 
  reticulated 
  to 
  

   the 
  base. 
  The 
  lower 
  reticulations 
  are 
  usually 
  coarser 
  but 
  less 
  per-
