  It 
  is 
  allied 
  to 
  C. 
  micaceus. 
  but 
  is 
  thinner, 
  more 
  fragile, 
  

   darker 
  in 
  color, 
  with 
  more 
  narrow 
  lamellae 
  which 
  are 
  

   darker 
  in 
  the 
  young 
  plant. 
  The 
  species 
  is

  This 
  seems 
  to 
  be 
  the 
  American 
  analogue 
  of 
  the 
  European 
  

   H. 
  oorusseus. 
  After 
  considerable 
  hesitation 
  I 
  have 
  ventured 
  

   to 
  separate 
  it 
  as 
  a 
  species 
  because 
  of 
  its 
  smaller 
  size 
  and 
  the 
  

   red 
  color 
  of 
  the 
  edge 
  of 
  the 
  lamella?, 
  a 
  singular 
  character 
  

   which 
  has 
  suggested 
  the 
  specific 
  name.

  The 
  stem 
  and 
  pileus 
  are 
  slightly 
  viscid 
  when 
  young 
  and 
  

   moist. 
  The 
  stem 
  is 
  sometimes 
  more 
  highly

  the 
  

   pileus.
