  In 
  this 
  section 
  the 
  species 
  have 
  the 
  pileus 
  either 
  viscid 
  or 
  glutinous 
  

   when 
  moist, 
  and 
  in 
  most 
  of 
  them 
  the 
  viscid 
  pellicle 
  is 
  separable 
  from 
  

   the 
  flesh. 
  The 
  flesh, 
  when 
  cut 
  or 
  exposed 
  to 
  the 
  air 
  does 
  not, 
  with 
  

   one 
  exception, 
  assume 
  the 
  bluish 
  tints 
  so 
  often 
  seen 
  in 
  some 
  of 
  the 
  

   members 
  of 
  other 
  sections, 
  yet 
  in 
  some, 
  dull-pinkish 
  or 
  more 
  obscure 
  

   tints 
  appear. 
  In 
  mature 
  plants 
  it 
  generally 
  becomes 
  soft, 
  almost 
  

   floccose 
  or 
  cottony 
  in 
  texture. 
  The 
  tubes 
  are 
  mostly 
  adnate 
  or 
  even 
  

   slightly 
  decurrent. 
  In 
  rare 
  instances 
  they 
  may 
  be 
  somewhat 
  de- 
  

   pressed 
  around 
  the 
  stem. 
  The 
  pores 
  are 
  usually 
  of 
  medium 
  or 
  large 
  

   size 
  and 
  frequently 
  angular. 
  The 
  dissepiments 
  are 
  often 
  uneven 
  or 
  

   dentate. 
  The 
  mouths 
  are 
  colored 
  like 
  the 
  rest 
  of 
  the 
  tubes. 
  Yellow 
  

   or 
  ochraceous 
  hues 
  prevail, 
  but 
  the 
  tubes 
  when 
  young 
  are 
  paler 
  than 
  

   when 
  mature. 
  The 
  stem 
  is 
  not 
  distinctly 
  bulbous, 
  is 
  always 
  solid 
  

   and 
  generally 
  glabrous 
  or 
  merely 
  dotted. 
  It 
  is 
  annulate 
  in 
  some, 
  

   naked 
  in 
  others. 
  In 
  several 
  closely 
  related 
  central 
  species 
  of 
  the 
  

   group 
  it, 
  as 
  well 
  as 
  the 
  tubes, 
  exudes, 
  when 
  young, 
  drops 
  of 
  a 
  thick, 
  

   gummy 
  fluid, 
  which 
  soon 
  hardens, 
  becomes 
  darker 
  and 
  forms 
  sugary 
  

   granules 
  or 
  glandular 
  dots. 
  The 
  color 
  of 
  the 
  spores 
  is 
  by 
  no 
  means 
  

   uniform, 
  but 
  it 
  is 
  some 
  shade 
  of 
  ochraceous, 
  ferruginous 
  or 
  brown. 
  

   The 
  first 
  and. 
  last 
  species 
  here 
  described 
  are 
  exceptional 
  by 
  their 
  

   slight 
  viscidity. 
  The 
  first 
  is 
  also 
  exceptional 
  by 
  its 
  universal 
  tomen- 
  

   tose-pulverulent 
  veil. 
  Several 
  species 
  are 
  edible. 
  Nearly 
  all 
  occur 
  

   in 
  regions 
  inhabited 
  by 
  pine 
  or 
  other 
  coniferous 
  trees, 
  and 
  are 
  want- 
  

   ing 
  in 
  localities 
  destitute 
  of 
  these 
  trees.
