  in 
  the 
  character 
  of 
  the 
  lamellae 
  this 
  plant 
  bears 
  some 
  

   resemblance 
  to 
  Marasmius 
  oreades, 
  but 
  in 
  other 
  respects 
  it 
  is 
  far 
  dif- 
  

   ferent.

  belongs 
  to

  is 
  related 
  to 
  

   C. 
  acervata, 
  C. 
  Familia, 
  etc. 
  The 
  plants 
  are 
  quite 
  regular

  This 
  

   species 
  is 
  very 
  rare 
  with 
  us, 
  but 
  it 
  is 
  well 
  marked

  the 
  gelatinous 
  

   upper

  The 
  plants 
  referred 
  to 
  this 
  species 
  in 
  Report 
  24, 
  p.

  proved 
  to 
  be 
  

   distinct 
  and 
  were

  The 
  plants 
  now 
  under 
  consideration 
  agree 
  well 
  with 
  

   the 
  description 
  and 
  figures 
  of

  are
