  The 
  relationship 
  of 
  this 
  plant 
  is 
  with 
  L. 
  serifluus, 
  to 
  

   which 
  it 
  was 
  formerly 
  referred, 
  but 
  from 
  which 
  I 
  am 
  now 
  

   satisfied 
  it 
  is 
  distinct. 
  The 
  hollow 
  stem 
  is 
  a 
  constant 
  

   character 
  in 
  our 
  plant, 
  and 
  affords 
  a 
  ready 
  mark 
  of 
  distinc- 
  

   tion. 
  The 
  plant, 
  though 
  large, 
  is 
  very 
  fragile, 
  and 
  breaks 
  

   easily. 
  The 
  taste 
  is 
  mild 
  or 
  but 
  slightly 
  acrid. 
  Sometimes 
  

   there 
  is 
  an 
  obscure 
  zonation 
  on 
  the 
  pileus, 
  which, 
  in 
  large 
  

   specimens, 
  is 
  apt 
  to 
  be 
  irregular 
  and 
  much 
  worm-eaten. 
  

   The 
  milk 
  looks 
  like 
  little 
  drops 
  of 
  water 
  when 
  first 
  issuing 
  

   from 
  a 
  wound, 
  but 
  it 
  becomes 
  a 
  little 
  less 
  clear 
  on 
  exposure 
  

   to 
  the 
  atmosphere. 
  The 
  decided 
  but 
  agreeable 
  odor 
  of 
  the 
  

   dried 
  specimens 
  persists 
  a 
  long 
  time.

  The 
  small 
  size 
  and 
  white 
  mealy 
  pruinosity 
  are 
  distin- 
  

   guishing 
  features 
  in 
  this 
  species. 
  But 
  for 
  the 
  obtuse 
  edge 
  

   of 
  the 
  lamellae 
  it 
  might 
  readily 
  be 
  taken 
  for 
  some 
  small 
  

   Omphalia, 
  especially 
  as 
  the 
  lamellae 
  are 
  not 
  branched.
