  Pileus 
  thin, 
  campanulate 
  or 
  convex, 
  obtuse, 
  glabrous, 
  hygroph- 
  

   anous, 
  brown 
  or 
  reddish 
  brown 
  when 
  moist, 
  paler 
  when 
  dry 
  ; 
  gills 
  

   broad, 
  adnate, 
  minutely 
  crenulate 
  on 
  the 
  edge, 
  ventricose, 
  subdis- 
  

   tant, 
  brown 
  ; 
  stem 
  slender, 
  nearly 
  straight, 
  hollow, 
  rigid, 
  fragile, 
  

   glabrous, 
  pruinose 
  at 
  the 
  top, 
  pallid 
  or

  spores 
  brown,

  The 
  haymakers 
  psilocybe 
  is 
  a 
  small 
  but 
  very 
  regular, 
  neat 
  and 
  

   attractive 
  species 
  which 
  gets 
  its 
  name 
  from 
  its 
  usual 
  place 
  of 
  

   growth. 
  This 
  is 
  in 
  grassy 
  places, 
  on 
  lawns 
  or 
  in 
  meadows, 
  where 
  

   it 
  is 
  often 
  destroyed 
  by 
  the 
  mower 
  while 
  cutting 
  grass. 
  Its 
  cap 
  

   is 
  conic 
  or 
  somewhat 
  bell 
  shaped 
  when 
  young, 
  but 
  it 
  becomes 
  

   more 
  convex 
  with 
  age. 
  When 
  fresh 
  and 
  moist 
  it 
  is 
  dark 
  brown 
  or 
  

   reddish 
  brown 
  and 
  is 
  usually 
  marked 
  on 
  the 
  margin 
  by 
  darker 
  

   parallel 
  radiating 
  lines. 
  By 
  the 
  escape 
  of 
  the 
  surplus 
  moisture 
  

   these 
  lines 
  disappear 
  and 
  the 
  cap 
  becomes 
  paler, 
  assuming 
  a 
  

   grayish 
  or 
  ashy 
  gray 
  color. 
  The 
  moisture 
  generally 
  escapes 
  first 
  

   from 
  the 
  center 
  of 
  the 
  cap 
  though 
  the 
  flesh 
  is 
  thicker 
  there 
  than 
  

   on 
  the 
  margin. 
  This 
  gives 
  a 
  somewhat 
  variegated 
  appearance 
  to 
  

   the 
  cap 
  while 
  the 
  moisture 
  is 
  escaping, 
  but 
  after 
  the 
  evaporation 
  

   is 
  completed 
  the 
  color 
  is 
  nearly 
  uniform. 
  Sometimes 
  the 
  center 
  

   of 
  the 
  cap 
  has 
  a 
  reddish 
  or 
  tan 
  colored 
  hue, 
  in 
  which 
  case 
  this 
  

   color 
  is 
  generally 
  retained 
  for 
  a 
  time 
  after 
  the 
  escape 
  of 
  the 
  

   moisture. 
  The 
  cap 
  is 
  generally 
  brown 
  in 
  completely 
  dried 
  and 
  

   shriveled 
  specimens. 
  The 
  gills 
  are 
  rather 
  broad, 
  not 
  crowded, 
  

   somewhat 
  narrowed 
  behind 
  and 
  attached 
  to 
  the 
  stem. 
  They 
  are 
  

   pale 
  brown 
  when 
  young, 
  blackish 
  brown 
  when 
  old. 
  The 
  stem 
  is 
  

   slender, 
  usually 
  long 
  and 
  nearly 
  straight, 
  hollow, 
  easily 
  broken 
  

   and 
  paler 
  than 
  the 
  moist 
  cap. 
  It 
  is 
  sometimes 
  tinged 
  with 
  red. 
  

   The 
  spores 
  in 
  our 
  plant 
  slightly 
  exceed 
  the 
  dimensions 
  given 
  to 
  

   the 
  spores 
  of 
  the 
  Euror>ean 
  plant. 
  

  

  The 
  cap 
  is 
  6-12 
  lines 
  broad; 
  the 
  stem 
  2-3 
  inches 
  long, 
  about 
  1 
  

   line 
  thick. 
  This 
  mushroom 
  grows 
  gregariously 
  in 
  rich 
  grassy 
  

   places, 
  generally 
  appearing 
  in 
  May 
  and 
  June. 
  Sometimes 
  it 
  ap- 
  

   pears 
  in 
  great 
  numbers 
  and 
  in 
  successive 
  crops, 
  otherwise 
  it 
  would
