  Peridium 
  whitish, 
  fugacious, 
  except 
  at 
  the 
  base, 
  externally 
  

   mealy 
  with 
  lime

  stem 
  white,

  The 
  fragments 
  of 
  the 
  base 
  of 
  the 
  peridium 
  sometimes 
  remain 
  

   just 
  below 
  the 
  capillitium, 
  surrounding 
  the 
  stem 
  like 
  a 
  calyx 
  

   or 
  collar. 
  The 
  stem 
  is 
  even 
  and 
  generally 
  longer 
  than 
  the 
  

   peridium 
  which 
  it 
  penetrates. 
  After 
  the 
  spores 
  have 
  fallen 
  the 
  

   whitish 
  color 
  of 
  the 
  capillitium 
  becomes 
  apparent. 
  It 
  then 
  

   resembles 
  a 
  small 
  globose 
  tuft 
  of 
  wool. 
  The 
  plants 
  grew 
  on 
  

   the 
  branches 
  and 
  mosses 
  of 
  a 
  standing 
  dead 
  birch 
  tree. 
  

   Didymium

  This 
  is 
  a 
  very 
  pretty 
  and 
  distinct 
  species. 
  The 
  globose 
  

   peridia 
  and 
  rough 
  spores 
  make 
  it 
  easily 
  recognized. 
  It 
  is 
  near 
  

   D. 
  elegans 
  in 
  color, 
  but 
  at 
  once 
  distinguished 
  from 
  it 
  by 
  its 
  

   globose 
  peridium.
