  The 
  very 
  bitter 
  taste 
  is 
  suggestive 
  of 
  the 
  specific 
  name.

   is

  viscid

  The 
  late 
  Mr. 
  C. 
  C. 
  Frost 
  sent 
  me 
  specimens 
  and 
  manuscript 
  descrip- 
  

   tions 
  of 
  a 
  few 
  species 
  of 
  fungi 
  collected 
  by 
  him 
  in 
  Vermont. 
  He 
  gave 
  

   names 
  to 
  those 
  which 
  he 
  considered 
  new 
  species, 
  and 
  it 
  gives 
  me 
  

   pleasure 
  to 
  adopt 
  his 
  names 
  whenever 
  it 
  is 
  rendered 
  possible 
  by 
  the 
  

   discovery 
  of 
  the 
  species 
  within 
  our 
  limits. 
  The 
  plant 
  here 
  described 
  

   does 
  not 
  fully 
  agree 
  with 
  his 
  manuscript 
  description, 
  which 
  I 
  have 
  

   quoted, 
  but 
  it 
  approaches 
  so 
  near 
  an 
  agreement 
  that 
  there 
  cannot 
  be 
  

   much 
  doubt 
  of 
  the 
  specific 
  identity 
  of 
  the 
  two 
  plants. 
  In 
  our 
  plant 
  

   the 
  pileus 
  is 
  sometimes 
  split 
  on 
  the 
  margin. 
  The 
  change 
  in 
  the 
  color 
  

   of 
  the 
  pileus 
  and 
  stem 
  is 
  nearly 
  the 
  same, 
  but 
  the 
  lamellae 
  sometimes 
  

   become 
  darker 
  than 
  either. 
  When 
  drying, 
  the 
  specimens 
  emit
