  deeper 
  hues 
  and 
  may 
  be 
  tinged 
  with 
  ferruginous 
  in 
  the 
  center. 
  The 
  

   margin 
  is 
  generally 
  adorned 
  with 
  pale 
  yellow 
  or 
  whitish 
  webby 
  fibrils 
  

   which 
  are 
  sometimes 
  slightly 
  interwoven. 
  Usually 
  they 
  are 
  appen- 
  

   diculate 
  to 
  the 
  margin 
  of 
  the 
  expanded 
  pileus, 
  but 
  occasionally 
  they 
  

   adhere 
  in 
  part 
  to 
  the 
  stem 
  and 
  form 
  a 
  kind 
  of 
  evanescent 
  annulus. 
  

   The 
  lamellae 
  vary 
  at 
  their 
  inner 
  extremity, 
  being 
  either 
  rounded 
  

   behind, 
  adnate 
  or 
  slightly 
  decurrent. 
  The 
  plants 
  do 
  not 
  inhabit 
  

   alders 
  alone 
  as 
  might 
  be 
  inferred 
  from 
  the 
  specific 
  name, 
  but 
  they 
  

   also 
  occur 
  on 
  birch 
  and 
  wood 
  of 
  other 
  deciduous 
  trees 
  and 
  on 
  the 
  

   ground.

  of

   tainous 
  districts. 
  Summer 
  and 
  autumn. 
  

  

  Our 
  specimens 
  were 
  found 
  on 
  wood 
  of 
  both 
  coniferous 
  and 
  decidu- 
  

   ous 
  trees. 
  The 
  plants 
  are 
  sometimes 
  caespitose. 
  The 
  pileus 
  becomes 
  

   more 
  highly 
  colored 
  in 
  drying. 
  The 
  spores 
  are 
  pale 
  ferruginous 
  

   approaching 
  ochraceous. 
  In 
  Sylloge 
  the 
  spores 
  of 
  this 
  species 
  are 
  

   described 
  as 
  pale 
  yellowish.
