  Agaricus 
  (Collybia) 
  coistigenoides 
  Ellis. 
  

  

  Buried 
  pine 
  cones. 
  West 
  Albany. 
  October. 
  

  

  The 
  pileus 
  in 
  our 
  specimens 
  is 
  fuscous, 
  being 
  darker 
  than 
  in 
  

   the 
  type. 
  It 
  seems 
  to 
  be 
  near 
  A. 
  semihcerens 
  B. 
  & 
  C, 
  if 
  not 
  

   indeed 
  the 
  same 
  species. 
  

  

  Agaricus 
  (Collybia) 
  delicatellus 
  n. 
  sp. 
  

  

  Snowy- 
  white 
  throughout, 
  smooth, 
  subcaespitose 
  ; 
  pileus 
  con- 
  

   vex 
  or 
  broadly 
  campanulate, 
  submembranaceous, 
  slightly 
  

   thicker 
  on 
  the 
  disk 
  ; 
  lamellae 
  narrow, 
  close, 
  emarginate 
  ; 
  stem 
  

   slender, 
  equal, 
  hollow, 
  slightly 
  white-villous 
  at 
  the 
  base. 
  

  

  Plant 
  1' 
  high, 
  pileus 
  2"-3" 
  broad, 
  stem 
  .5" 
  thick. 
  

  

  Among 
  fallen 
  leaves. 
  North 
  Greenbush. 
  September. 
  

   From 
  the 
  character 
  of 
  the 
  lamellae 
  it 
  is 
  evidently 
  a 
  Collybia 
  

   but 
  the 
  substance 
  is 
  rather 
  tender.

  elliptical, 
  

   .0002'

  a 
  long 
  time 
  persistent.

  Apparently 
  near 
  A

  but 
  smaller 
  and 
  easily 
  

   known 
  by 
  its 
  decided 
  and 
  peculiar 
  odor 
  which 
  is 
  retained 
  by 
  

   the 
  dried 
  specimens 
  for 
  a 
  long 
  time.
