  This 
  is 
  allied 
  to 
  A. 
  gracilis 
  Fr., 
  but 
  the 
  edge 
  of 
  the 
  lamellae 
  

   is 
  not 
  rosy. 
  When 
  drying 
  the 
  moisture 
  leaves 
  the 
  disk 
  of 
  the 
  

   pileus 
  first, 
  the 
  margin 
  last. 
  When 
  dry 
  the 
  plant 
  bears 
  some 
  

   resemblance 
  to 
  large 
  forms 
  of 
  A. 
  tener.
