  The 
  striated 
  appearance 
  of 
  the 
  lamellae 
  is 
  due 
  to 
  the 
  presence 
  

   of 
  small 
  transverse 
  vein-like 
  elevations. 
  The 
  stem 
  is 
  almost 
  

   chalky- 
  white. 
  The 
  odor 
  is 
  quite 
  perceptible 
  and 
  peculiar.

  A 
  small 
  species 
  remarkable 
  for 
  its 
  peculiar 
  habitat. 
  Some- 
  

   times 
  the 
  stems 
  of 
  two 
  or 
  three 
  plants 
  are 
  united 
  at 
  the 
  base, 
  

   thus 
  manifesting 
  a 
  tendency 
  to 
  become 
  caespitose.
