  Agaricus 
  (Naucoria) 
  contraritjs 
  n. 
  sp. 
  

  

  Pileus 
  thin, 
  convex, 
  then 
  plane 
  or 
  centrally 
  depressed, 
  some- 
  

   times 
  umbilicate 
  and 
  striate 
  on 
  the 
  margin, 
  glabrons, 
  alutace- 
  

   ous 
  ; 
  lamellae 
  loose, 
  adnate, 
  very 
  broad 
  behind, 
  becoming 
  

   ventricose 
  and 
  subtriangular, 
  ochraceous 
  ; 
  stem 
  equal, 
  hollow, 
  

   reddish 
  or 
  reddish-brown, 
  adorned 
  with 
  a 
  few 
  silky-fibrils 
  and 
  

   minute 
  fragments 
  of 
  the 
  white 
  floccose 
  veil 
  ; 
  spores 
  yellow, 
  

   elliptical, 
  .0003' 
  long, 
  .0002' 
  broad. 
  

  

  Plant 
  gregarious 
  or 
  subcaespitose, 
  about 
  1' 
  high, 
  pileus 
  6"-10" 
  

   broad. 
  

  

  Grassy 
  ground 
  in 
  pastures. 
  Schenevus 
  and 
  West 
  Albany. 
  

   September. 
  

  

  The 
  color 
  of 
  the 
  pileus 
  fades 
  a 
  little 
  with 
  age, 
  but 
  the 
  bright 
  

   color 
  of 
  the 
  lamellae 
  is 
  retained 
  longer. 
  There 
  is 
  usually 
  an 
  

   abundant 
  white 
  mycelium 
  at 
  the 
  base 
  of 
  the 
  stem. 
  Often 
  min- 
  

   ute 
  fragments 
  of 
  the 
  floccose 
  veil 
  may 
  be 
  seen 
  on 
  the 
  margin 
  of 
  

   the 
  young 
  pileus. 
  

  

  Agaricus 
  (Stropharia) 
  umbonatescens 
  n. 
  sp. 
  

  

  Pileus 
  at 
  first 
  conical, 
  subacute, 
  then 
  expanded 
  and 
  umbon- 
  

   ate, 
  smooth, 
  viscid, 
  yellow, 
  the 
  umbo 
  inclining 
  to 
  reddish 
  ; 
  

   lamellae 
  plane, 
  broad, 
  at 
  length 
  ventricose, 
  blackish-brown 
  with 
  

   a 
  slight 
  olivaceous 
  tint 
  ; 
  stem 
  equal, 
  slender, 
  hollow, 
  generally 
  

   a 
  little 
  paler 
  than 
  the 
  pileus 
  ; 
  spores 
  purplish-brown, 
  almost 
  

   black, 
  .0006 
  '--0007' 
  long, 
  .0004' 
  broad. 
  

  

  Plant 
  3-4' 
  high, 
  pileus 
  6"-12" 
  broad. 
  

  

  Dung 
  in 
  pastures. 
  Schenevus. 
  September. 
  

  

  This 
  is 
  evidently 
  closely 
  allied 
  to 
  A. 
  stercorarius 
  and 
  A. 
  

   semiglobatus 
  with 
  which 
  it 
  has 
  probably 
  been 
  confounded, 
  but 
  

   the 
  pileus 
  in 
  our 
  plant 
  is 
  so 
  peculiar 
  in 
  form 
  that 
  I 
  am 
  con- 
  

   strained 
  to 
  regard 
  it 
  as 
  a 
  distinct 
  species. 
  The 
  viscid 
  pellicle 
  

   of 
  the 
  pileus 
  is 
  separable. 
  When 
  old 
  it 
  sometimes 
  cracks 
  into 
  

   areas.

  Our 
  specimens 
  do 
  not 
  agree 
  in 
  all 
  respects 
  with 
  the 
  published 
  

   description 
  of 
  the 
  species. 
  The 
  pileus 
  is 
  sometimes 
  wholly 
  

   destitute 
  of 
  scales 
  and 
  sometimes 
  densely 
  clothed 
  with 
  hairy 
  

   erect 
  ones. 
  The 
  species 
  is 
  manifestly 
  variable.
