  angular 
  or 
  subrotund, 
  pale-yellow 
  when 
  young, 
  becoming 
  dingy- 
  

   ochraceous, 
  changing 
  to 
  purplish-brown 
  where 
  bruised 
  ; 
  stem 
  equal 
  

   or 
  slightly 
  thickened 
  at 
  the 
  base, 
  straight 
  or 
  flexuous, 
  annulate, 
  

   yellow 
  at 
  the 
  apex, 
  elsewhere 
  reddish 
  or 
  reddish-brown, 
  sometimes 
  

   stained 
  with 
  yellow, 
  slightly 
  reticulate 
  at 
  the 
  apex 
  by 
  the 
  decurrent 
  

   walls 
  of 
  the 
  tubes, 
  annulus 
  whitish 
  or 
  yellow, 
  persistent, 
  forming 
  a 
  

   thick 
  tomentose 
  band 
  about 
  the 
  stem 
  ; 
  spores 
  brownish- 
  ochraceous,

  to

  or 
  rarely

  to 
  

   5 
  in. 
  long,

  Mossy 
  ground 
  in 
  woods 
  and 
  grassy 
  ground 
  in 
  open 
  places 
  ; 
  gener- 
  

   ally 
  under 
  or 
  near 
  larch 
  trees. 
  

  

  This 
  fine 
  species 
  is 
  apparently 
  the 
  American 
  analogue 
  of 
  the 
  Euro- 
  

   pean 
  B. 
  elegans, 
  from 
  which 
  it 
  differs 
  in 
  its 
  generally 
  darker 
  color, 
  

   in 
  its 
  persistent, 
  not 
  fugacious, 
  annulus, 
  and 
  in 
  its 
  stem, 
  which 
  is 
  not 
  

   at 
  all 
  dotted, 
  either 
  above 
  or 
  below 
  the 
  annulus. 
  It 
  is 
  edible, 
  and 
  

   has 
  a 
  mild 
  taste 
  in 
  the 
  fresh 
  uncooked 
  state. 
  It 
  has 
  occurred 
  once 
  

   in 
  Washington 
  Park, 
  Albany, 
  near 
  some 
  larch 
  trees, 
  with 
  which 
  it 
  was 
  

   probably 
  introduced. 
  

  

  Boletus 
  luteus 
  L. 
  

   Yellow- 
  brown 
  Boletus. 
  

  

  Pileus 
  gibbous 
  or 
  convex, 
  sometimes 
  nearly 
  plane, 
  viscid 
  or 
  glutin- 
  

   ous 
  when 
  moist, 
  virgate-spotted, 
  yellowish-brown, 
  flesh 
  white 
  or 
  yel- 
  

   lowish 
  ; 
  tubes 
  small, 
  simple, 
  adnate, 
  at 
  first 
  pale-yellow, 
  then 
  dingy- 
  

   ochraceous 
  ; 
  stem 
  stout, 
  rather 
  short, 
  annulate, 
  rough 
  with 
  dots 
  and 
  

   yellowish 
  above 
  the 
  ring, 
  brownish-white 
  or 
  yellowish 
  below, 
  the 
  annu- 
  

   lus 
  large, 
  membranous, 
  whitish 
  or 
  brownish- 
  white 
  ; 
  spores 
  ochraceo- 
  

   ferruginous, 
  nearly 
  fusiform, 
  .0003 
  in. 
  long, 
  .00015 
  broad. 
  

  

  Gregarious 
  or 
  rarely 
  subcaespitose, 
  pileus 
  2 
  to 
  5 
  in. 
  broad, 
  stem 
  

   1 
  to 
  2 
  in. 
  long, 
  5 
  to 
  8 
  lines 
  thick.

  This 
  is 
  the 
  only 
  instance 
  in 
  which 
  I 
  have 
  observed 
  this 
  species 
  in 
  our 
  

   State. 
  Possibly 
  it 
  may 
  have 
  been 
  introduced 
  in 
  this 
  place 
  with 
  the 
  

   young 
  pines 
  under 
  which 
  it 
  was 
  growing. 
  Its 
  annulus 
  is 
  very 
  conspicu- 
  

   ous. 
  It 
  is 
  sometimes 
  torn 
  and 
  partly 
  adherent 
  in 
  fragments 
  to 
  the 
  mar- 
  

   gin 
  of 
  the 
  pileus. 
  In 
  short-stemmed 
  specimens 
  it 
  extends 
  downwards 
  

   and 
  covers 
  the 
  lower 
  part 
  of 
  the 
  stem 
  like 
  a 
  sheath, 
  resembling 
  in 
  this 
  

   respect 
  the 
  western 
  Boletus 
  sj)hcerosporus, 
  a 
  related 
  species. 
  In 
  other 
  

   specimens 
  it 
  forms 
  a 
  broad 
  band 
  with 
  the 
  uppei 
  margin 
  widely 
  spread- 
  

   ing. 
  In 
  the 
  dried 
  specimens 
  the 
  pileus 
  has 
  assumed 
  a 
  dull-brownish 
  

   or 
  reddish-brown 
  hue. 
  The 
  plant 
  is 
  edible.
