  from 
  its

  by 
  its

  color.

  differs 
  in 
  having

   a

  JVoIanea 
  delicatulus 
  is 
  a 
  more 
  slender, 
  delicate 
  plant 
  

   with 
  a 
  smoother 
  pileus 
  and 
  not 
  at 
  all 
  umbilicate. 
  

  

  Psilocybe

  Pileus 
  thin, 
  at 
  first 
  convex 
  or 
  subcorneal, 
  then 
  expanded 
  or 
  slightly 
  

   depressed, 
  glabrous, 
  hygrophanous, 
  chestnut-colored 
  or 
  umber-brown 
  

   and 
  striatulate 
  on 
  the 
  margin 
  when 
  moist, 
  pale-alutaceous 
  when 
  dry, 
  

   flesh 
  a 
  little 
  paler 
  than 
  the 
  surface 
  of 
  the 
  pileus 
  ; 
  lamellae 
  close, 
  

   adnate 
  or 
  slightly 
  rounded 
  behind, 
  at 
  first 
  pale-brown, 
  then 
  purplish- 
  

   brown 
  ; 
  stem 
  equal, 
  flexuous, 
  hollow 
  or

  with 
  a 
  whitish 
  pith, 
  

   slightly 
  silky-fibrillose, 
  brownish 
  or

  June. 
  

  

  The 
  species 
  appears 
  to 
  be 
  closely 
  allied 
  to 
  Agaricus 
  squalens, 
  

   which 
  may 
  be 
  distinguished 
  by 
  its 
  lurid 
  color, 
  decurrent 
  lamellae 
  

   and 
  ferruginous-brown 
  spores. 
  Moreover 
  its 
  habitat 
  is 
  unlike 
  that 
  

   of 
  our 
  plant. 
  In 
  very 
  wet 
  weather 
  both 
  the 
  pileus 
  and 
  lamellae 
  

   sometimes 
  have 
  a 
  watery-brown 
  appearance, 
  and 
  then 
  the 
  striations 
  

   of 
  the 
  former 
  sometimes 
  extend 
  to 
  the 
  disk, 
  which 
  is 
  rarely 
  slightly 
  

   umbonate. 
  In 
  drying, 
  the 
  moisture 
  first 
  disappears 
  from 
  the 
  center 
  

   of 
  the 
  pileus. 
  The 
  young 
  pileus 
  is 
  usually 
  chestnut-colored, 
  and 
  its 
  

   margin 
  and 
  the 
  stem 
  are 
  adorned 
  with 
  a 
  few 
  whitish 
  fibrils. 
  

  

  Psilocybe 
  fuscofulva. 
  

  

  Pileus 
  thin, 
  convex 
  or 
  subcampanulate, 
  subumbonate, 
  glabrous, 
  

   hygrophanous, 
  dark 
  watery-brown 
  and 
  striatulate 
  on 
  the 
  margin 
  

   when 
  moist, 
  subochraceous 
  when 
  dry 
  ; 
  lamellae 
  rather 
  broad, 
  mod- 
  

   erately 
  close, 
  adnate, 
  subventricose, 
  purplish-brown 
  ; 
  stem 
  slender, 
  

   flexuous, 
  stuffed, 
  slightly 
  silky, 
  reddish-brown 
  ; 
  spores 
  purplish- 
  

   brown, 
  .0004 
  to 
  .0005 
  in. 
  long, 
  .00025 
  to 
  .0003 
  in. 
  broad. 
  

  

  Plant 
  1.5 
  to 
  2.5 
  in. 
  high, 
  pileus 
  6 
  to 
  12 
  lines 
  broad, 
  stem 
  1 
  to 
  2 
  

   lines 
  thick. 
  

  

  Among 
  sphagnum. 
  Karner. 
  October. 
  

  

  The 
  species 
  is 
  related 
  to 
  Agaricus 
  atrobrunneus, 
  but 
  its 
  smaller 
  size 
  

   and 
  cliflerently 
  colored 
  lamellae 
  will 
  serve 
  to 
  distinguish 
  it.
