  A 
  singular 
  species 
  remarkable 
  for 
  its 
  boletoid 
  or 
  porous 
  hyme- 
  

   nium. 
  It 
  is 
  thus 
  far 
  peculiar 
  to 
  this 
  country. 
  Its 
  spores, 
  according 
  

   to 
  Prof. 
  A. 
  P. 
  Morgan, 
  are 
  bright-yellow. 
  They 
  are 
  larger 
  than 
  in 
  

   any 
  of 
  our 
  other 
  species 
  of 
  Paxillus. 
  The 
  author 
  of 
  the 
  species 
  

   makes 
  the 
  remark 
  that 
  " 
  without 
  examining 
  the 
  fructification 
  it 
  

   might 
  be 
  taken 
  for 
  a 
  Boletus." 
  It 
  is 
  admitted 
  that 
  the 
  spores 
  are 
  

   broader 
  in 
  proportion 
  to 
  their 
  length 
  than 
  are 
  the 
  spores 
  of 
  most 
  

   Boleti, 
  but 
  in 
  Boletus 
  strobilaceus 
  the 
  spores 
  make 
  quite 
  as 
  wide 
  a 
  

   departure 
  from 
  the 
  ordinary 
  form. 
  In 
  fresh 
  specimens 
  the 
  radiating 
  

   lamellae 
  are 
  distinguishable, 
  being 
  somewhat 
  broader 
  than 
  the 
  con- 
  

   necting 
  veins 
  or 
  branches, 
  but 
  in 
  the 
  dried 
  specimens 
  this 
  difference 
  

   is 
  so 
  obscured 
  that 
  the 
  hymenium 
  appears 
  in 
  no 
  manner 
  to 
  differ 
  

   from 
  that 
  of 
  some 
  of 
  the 
  large 
  and 
  angular-pored 
  Boleti. 
  Indeed 
  

   this 
  same 
  kind 
  of 
  union 
  of 
  radiating 
  lamellae 
  is 
  discernible 
  in 
  the 
  

   hymenium 
  of 
  Boletus 
  paluster 
  in 
  which 
  the 
  spores 
  approach 
  much 
  

   more 
  closely 
  to 
  the 
  ordinary 
  form 
  of 
  Boletus 
  spores 
  ; 
  from 
  which 
  it 
  

   may 
  be 
  inferred 
  that 
  if 
  the 
  species 
  just 
  described 
  is 
  a 
  genuine 
  

   Paxillus, 
  the 
  distinction 
  between 
  that 
  genus 
  and 
  the 
  genus 
  Boletus 
  

   is 
  very 
  slight 
  indeed, 
  consisting 
  in 
  this 
  case 
  merely 
  in 
  the 
  eccentric 
  

   or 
  lateral 
  stem. 
  

  

  The 
  stem 
  in 
  P. 
  porosus 
  is 
  most 
  often 
  lateral, 
  and 
  at 
  the 
  point 
  of 
  

   its 
  insertion 
  there 
  is 
  generally 
  an 
  excavation 
  in 
  the 
  margin 
  of 
  the 
  

   pileus 
  which 
  gives 
  to 
  it 
  a 
  somewhat 
  reniform 
  outline. 
  The 
  pileus 
  

   has 
  been 
  described 
  as 
  " 
  viscid 
  when 
  moist," 
  but 
  I 
  have 
  never 
  ob- 
  

   served 
  this 
  character 
  in 
  our 
  plant. 
  The 
  color 
  of 
  the 
  hymenium 
  in 
  

   the 
  fresh 
  plant 
  is 
  a 
  bright 
  chrome-yellow. 
  The 
  fresh 
  plant 
  some- 
  

   times 
  emits 
  a 
  disagreeable, 
  dirt-like 
  odor. 
  

  

  Paxillus 
  strigosus 
  Pk. 
  does 
  not 
  have 
  the 
  lamellae 
  branched 
  or 
  

   crisped 
  at 
  the 
  base, 
  and 
  it 
  has 
  been 
  omitted. 
  It 
  probably 
  belongs 
  

   rather 
  to 
  Inocybe.
