  Lake 
  Harris 
  and 
  Lake 
  Jimmy, 
  Essex 
  county. 
  At 
  the 
  latter 
  

   lake 
  it 
  is 
  associated 
  with. 
  Utricularia 
  resupinate 
  and 
  Myriop- 
  

   hyllum

  I 
  have 
  recently 
  received 
  these 
  three 
  species 
  

   from 
  Long 
  Island.

  Lake 
  Harris 
  and 
  Lake 
  Jimmy. 
  The 
  former 
  lake 
  affords 
  a 
  

   variety 
  of 
  water 
  plants, 
  including 
  Brasenia 
  peltata, 
  J\ 
  T 
  ymp7icea 
  

   odorata, 
  NupTiar 
  advena, 
  JV.

  Potamogeton

  Agaricus 
  detersibilis 
  PJc. 
  

  

  I 
  find 
  that 
  this 
  name 
  is 
  preoccupied 
  and 
  must 
  therefore 
  be 
  

   changed. 
  I 
  would 
  substitute 
  for 
  it 
  Agaricus 
  erinaeeetlus 
  Pk. 
  

  

  Agaricus 
  Johnsoneanus 
  P7c. 
  

  

  This 
  species 
  occurred 
  the 
  past 
  season 
  in 
  the 
  original 
  locality. 
  

   I 
  had 
  not 
  seen 
  it 
  till 
  then 
  since 
  its 
  discovery 
  in 
  1869. 
  

  

  Agaricus 
  (Crepidotus) 
  yersutus 
  n. 
  sp. 
  

  

  Pileus 
  at 
  first 
  resupinate, 
  then 
  reflexed, 
  sessile, 
  thin, 
  pure 
  

   white, 
  covered 
  by 
  a 
  soft 
  downy 
  villosity, 
  the 
  margin 
  incurved 
  ; 
  

   lamellae 
  rather 
  broad 
  and 
  subdistant, 
  terminating 
  in 
  an 
  eccen- 
  

   tric 
  point, 
  rounded 
  behind, 
  pale, 
  then 
  ferruginous 
  ; 
  stem 
  none 
  ; 
  

   spores 
  ferruginous-brown, 
  subelliptical, 
  .0004' 
  long. 
  

  

  Plant 
  gregarious, 
  4*-10* 
  broad. 
  

  

  Much 
  decayed 
  half-buried 
  wood, 
  vegetable 
  mold 
  and 
  even 
  

   rocks. 
  

  

  This 
  plant 
  was 
  reported 
  under 
  the 
  name 
  A. 
  cliimonopliilus 
  

   B. 
  & 
  Bi\, 
  but 
  it 
  is 
  evidently 
  a 
  distinct 
  species. 
  It 
  loves 
  very 
  

   damp 
  shaded 
  places, 
  frequently 
  growing 
  in 
  cavities 
  and 
  on 
  half 
  

   buried 
  wood, 
  as 
  if 
  avoiding 
  the 
  light. 
  The 
  villosity 
  is 
  of 
  a 
  

   peculiar 
  soft 
  and 
  delicate 
  character 
  and 
  is 
  easily 
  destroyed 
  by 
  

   handling 
  the 
  specimens. 
  

  

  CORTEN'ARIUS 
  COMMUNIS 
  Pk. 
  

  

  The 
  spores 
  of 
  this 
  plant 
  have 
  a 
  dull 
  brownish 
  tinge, 
  unlike 
  

   those 
  of 
  true 
  Cortinarii 
  and 
  much 
  like 
  those 
  of 
  some 
  species 
  of 
  

   Pholiota. 
  I 
  have 
  also 
  found 
  it 
  growing 
  from 
  buried 
  pine 
  chips,
