  A 
  large 
  species 
  externally 
  resembling 
  Lactarius 
  vellereus, 
  and 
  per- 
  

   haps 
  hitherto 
  confused 
  with 
  it, 
  but 
  easily 
  distinguished 
  from 
  it 
  by 
  the 
  

   absence 
  of 
  a 
  milky 
  juice 
  and 
  by 
  the 
  lamellae 
  which 
  are 
  crisped 
  near 
  

   the 
  base 
  and 
  which 
  soon 
  assume 
  a 
  peculiar 
  salmon-yellow 
  hue, 
  which 
  

   also 
  appears 
  in 
  the 
  spores 
  when 
  collected 
  on 
  white 
  paper. 
  This 
  

   change 
  of 
  color 
  begins 
  in 
  the 
  crisped 
  portion 
  near 
  the 
  stem 
  and 
  gradu- 
  

   ally 
  advances 
  toward 
  the 
  outer 
  extremity. 
  In 
  the 
  dried 
  specimens 
  the 
  

   lamellae 
  are 
  ochraceous-brown 
  and 
  they 
  have 
  the 
  edge 
  more 
  or 
  less 
  

   beaded 
  with 
  white 
  granules. 
  They 
  are 
  often 
  forked 
  near 
  the 
  outer 
  

   extremity 
  as 
  well 
  as 
  toward 
  the 
  inner. 
  The 
  length 
  of 
  the 
  stem 
  some- 
  

   times 
  scarcely 
  exceeds 
  its 
  breadth. 
  In 
  but 
  a 
  single 
  instance 
  was 
  it 
  

   eccentric, 
  and 
  in 
  that 
  case 
  the 
  pileus 
  was 
  lobed 
  and 
  irregular. 
  The 
  

   surface 
  of 
  the 
  pileus 
  is 
  sometimes 
  roughened 
  with 
  minute 
  pustules 
  or 
  

   papillae 
  and 
  sometimes 
  has 
  a 
  pitted 
  appearance. 
  Rarely 
  the 
  margin 
  

   is 
  obscurely 
  zonate. 
  The 
  taste 
  is 
  bitterish 
  and 
  unpleasant, 
  and 
  some 
  

   times 
  the 
  plant 
  emits 
  a 
  subacid 
  odor. 
  It 
  is 
  a 
  singular 
  species.

  Involute 
  Paxillus. 
  

  

  Pileus 
  compact, 
  convex 
  or 
  expanded, 
  sometimes 
  centrally

   pressed,

  viscid 
  when 
  moist, 
  varying 
  in 
  color 
  from 
  grayish
