  Hydro 
  cybe 
  praepallens. 
  

  

  Pileus 
  fleshy, 
  thin, 
  subcorneal, 
  then 
  convex 
  or 
  expanded, 
  glabrous, 
  

   hygrophanous, 
  watery-brown 
  or 
  chestnut-colored 
  when 
  moist, 
  pale- 
  

   ochraceous 
  when 
  dry, 
  flesh 
  yellowish-white 
  ; 
  lamellae 
  close, 
  lanceolate, 
  

   rounded 
  behind 
  or 
  slightly 
  emarginate, 
  reddish-umber, 
  becoming 
  

   tawny-cinnamon

  The 
  difference 
  in 
  the 
  color 
  of 
  the 
  moist 
  pileus 
  and 
  the 
  dry 
  one 
  is 
  

   quite 
  decided. 
  The 
  change 
  from 
  the 
  dark-chestnut 
  color 
  of 
  the 
  one 
  

   to 
  the 
  dingy-yellow 
  or 
  isabelline 
  hue 
  of 
  the 
  other 
  is 
  very 
  noticeable 
  

   and 
  suggestive 
  of 
  the 
  specific 
  name. 
  The 
  fibrils 
  of 
  the 
  veil 
  are 
  

   grayish-white, 
  and 
  the 
  margin, 
  which 
  is 
  at 
  first 
  incurved, 
  is 
  apt 
  to 
  

   become 
  wavy, 
  irregular 
  or 
  reflexed 
  in 
  large 
  specimens. 
  In 
  the 
  

   thinner 
  specimens 
  it 
  is 
  striatulate 
  when 
  moist. 
  The 
  lamellae 
  are 
  nar- 
  

   rowed 
  toward 
  the 
  outer 
  extremity 
  and 
  when 
  young 
  are 
  of 
  a 
  peculiar 
  

   reddish-brown 
  or 
  dark-ferruginous 
  hue. 
  The 
  stem 
  is 
  usually 
  hollow, 
  

   but 
  apparently 
  from 
  the 
  erosion 
  of 
  insects. 
  The 
  species 
  belongs 
  to 
  

   the 
  section 
  Firmiores. 
  

  

  Hygrophorus 
  minutulus. 
  

  

  Pileus 
  thin, 
  submembranous, 
  convex 
  or 
  expanded, 
  subumbilicate, 
  

   bright-red, 
  viscid 
  and 
  distantly 
  striatulate 
  when 
  moist, 
  pale-red 
  or 
  

   yellowish 
  when 
  dry 
  ; 
  lamellae 
  rather 
  broad, 
  subdistant, 
  sometimes 
  

   ventricose, 
  adnate 
  or 
  subsinuate 
  and 
  slightly 
  clecurrent, 
  whitish, 
  

   tinged 
  with 
  red 
  or 
  yellow 
  ; 
  stem 
  short, 
  slender, 
  fragile, 
  solid, 
  viscid 
  

   when 
  moist, 
  yellowish 
  ; 
  spores 
  narrowly 
  elliptical, 
  .0004 
  in. 
  long, 
  

   .0002 
  in. 
  broad, 
  borne 
  on 
  slender 
  spicules 
  which 
  are 
  .0002 
  to 
  .0003 
  

   in. 
  long. 
  

  

  Plant 
  6 
  to 
  10 
  lines 
  high, 
  pileus 
  3 
  to 
  5 
  lines 
  broad, 
  stem 
  scarcely 
  

   half 
  a 
  line 
  thick. 
  

  

  Grassy 
  ground 
  in 
  pastures. 
  Sandlake. 
  July. 
  

  

  This 
  is 
  one 
  of 
  our 
  smallest 
  species 
  of 
  Hygrophorus. 
  Its 
  nearest 
  

   relative 
  is 
  H. 
  aurantiacoluteus 
  B. 
  & 
  C, 
  from 
  which 
  the 
  viscid 
  pileus 
  

   and 
  stem 
  and 
  less 
  clecurrent 
  lamellae 
  separate 
  it. 
  As 
  the 
  moisture 
  

   escapes 
  from 
  the 
  fresh 
  plant 
  the 
  pileus 
  becomes 
  paler 
  and 
  assumes 
  a 
  

   slight 
  silky 
  appearance, 
  but 
  often 
  the 
  thoroughly 
  dried 
  specimens
