  velvety 
  when

  by 
  the 
  

   aid 
  of 
  a

  This 
  is 
  due 
  to 
  the 
  abundance 
  of 
  the

  This 
  plant 
  is 
  manifestly 
  closely 
  allied 
  to 
  Hygrophoriis 
  conicus, 
  and 
  

   might 
  easily 
  be 
  considered 
  a 
  mere 
  variety 
  of 
  it. 
  It 
  differs, 
  however, 
  

   in 
  being 
  less 
  regularly 
  and 
  acutely 
  conical, 
  in 
  having 
  no 
  orange, 
  

   scarlet 
  or 
  red 
  hues, 
  in 
  its 
  paler 
  or 
  whitish 
  lamellae 
  and 
  specially 
  in 
  

   its 
  unchangeable 
  color. 
  Specimens 
  of 
  H. 
  conicus 
  collected 
  at 
  the 
  

   same 
  time 
  and 
  place

  tO' 
  the 
  same 
  method 
  of 
  drying 
  

   turned 
  black, 
  as 
  usual, 
  but 
  these 
  retained 
  their 
  colors.
