﻿OF 
  BRITISH 
  FUNGI. 
  43 
  

  

  of 
  these 
  sub-genera 
  do 
  we 
  recognise 
  any 
  species 
  that 
  is 
  

   edible. 
  

  

  The 
  series 
  called 
  Dermini. 
  which 
  have 
  rust-coloured 
  

   or 
  tawny 
  spores, 
  is 
  also 
  divided 
  into 
  sub-genera, 
  the 
  first 
  

   of 
  which 
  is 
  Pholiota, 
  probably 
  derived 
  from 
  the 
  Greek 
  

   pkolidotos, 
  and 
  "signifying 
  covered 
  with 
  scales," 
  which 
  

   is 
  a 
  characteristic 
  of 
  many 
  of 
  the 
  species. 
  In 
  this 
  group 
  

   the 
  stem 
  is 
  furnished 
  with 
  a 
  ring. 
  It 
  has 
  been 
  stated 
  

   that 
  A. 
  mutabilis, 
  a 
  member 
  of 
  this 
  sub-genus, 
  is 
  escu- 
  

   lent 
  ; 
  and, 
  having 
  tested 
  the 
  truth 
  of 
  the 
  assertion, 
  we 
  

   admit 
  it 
  as 
  such, 
  though 
  with 
  no 
  special 
  commendation. 
  

   Another 
  species 
  (A. 
  squarrosus), 
  which 
  is 
  commonly 
  

   found 
  D-rowing 
  in 
  dense 
  clumps 
  on 
  trunks 
  of 
  trees, 
  with 
  

   its 
  cap 
  and 
  stem 
  rough, 
  and 
  bristling 
  with 
  innumerable 
  

   dark 
  scales, 
  has 
  been 
  found 
  to 
  be 
  wholesome, 
  but 
  we 
  

   have 
  many 
  others 
  far 
  more 
  worthy 
  of 
  recommendation. 
  

  

  In 
  this 
  same 
  group 
  occurs 
  a 
  more 
  commendable 
  species 
  

   {A. 
  pudicus), 
  but 
  unfortunately 
  it 
  cannot 
  be 
  called 
  

   common. 
  The 
  pileus 
  is 
  fleshy, 
  smooth, 
  and 
  of 
  a 
  

   dirty-white 
  colour. 
  The 
  stem 
  is 
  solid 
  and 
  of 
  the 
  same 
  

   size 
  throughout 
  its 
  length. 
  The 
  gills 
  are 
  at 
  first 
  

   whitish 
  and 
  ultimately 
  tawny. 
  This 
  fungus 
  will 
  be 
  found 
  

   growing 
  on 
  trees, 
  more 
  particularly 
  on 
  elder 
  trunks, 
  and 
  

   has 
  been 
  recommended 
  as 
  wholesome 
  and 
  agreeable. 
  

  

  In 
  Hebeloma, 
  the 
  veil, 
  when 
  present 
  at 
  oil, 
  is 
  thread- 
  

   like, 
  and 
  the 
  gills 
  have 
  a 
  sinus 
  or 
  depression 
  at 
  the 
  

   extremity 
  next 
  the 
  stem. 
  Several 
  species 
  are 
  very 
  

   common, 
  but 
  none 
  are 
  esculent. 
  

  

  The 
  sub-genus 
  Flammula 
  has 
  the 
  gills 
  either 
  firmly 
  

   attached 
  to 
  or 
  running 
  down 
  the 
  stem.
