  PEEFACE 
  TO 
  THE 
  THlftD 
  EDITION. 
  

  

  A 
  Third 
  Edition 
  of 
  this 
  little 
  work 
  having 
  been 
  demanded, 
  

   I 
  have 
  taken 
  the 
  opportunity 
  of 
  making 
  a 
  few 
  verbal 
  cor- 
  

   rections 
  and 
  of 
  entirely 
  revising 
  the 
  Plates. 
  Some 
  of 
  the 
  

   figures 
  have 
  been 
  replaced 
  by 
  others 
  more 
  characterise 
  

   of 
  the 
  species, 
  but 
  in 
  no 
  case 
  has 
  the 
  individual 
  species 
  

   been 
  altered 
  from 
  what 
  it 
  was 
  in 
  the 
  first 
  and 
  second 
  

   editions. 
  In 
  the 
  colouring, 
  as 
  well 
  as 
  in 
  the 
  drawing, 
  

   it 
  is 
  hoped 
  that 
  the 
  illustrations 
  to 
  the 
  present 
  edition 
  

   will 
  be 
  found 
  more 
  satisfactory 
  than 
  in 
  either 
  of 
  the 
  

   preceding. 
  

  

  The 
  apologies 
  made 
  in 
  the 
  earlier 
  editions 
  of 
  this 
  work 
  

   for 
  its 
  production 
  are 
  no 
  longer 
  necessary, 
  since 
  its 
  ready 
  

   sale 
  has 
  justified 
  its 
  publication. 
  During 
  the 
  period 
  which 
  

   has 
  elapsed 
  a 
  considerable 
  addition 
  has 
  been 
  made 
  to 
  the 
  

   number 
  of 
  students 
  of 
  Fungi 
  in 
  this 
  country, 
  and 
  facilities 
  

   are 
  now 
  afforded 
  for 
  the 
  prosecution 
  of 
  that 
  study 
  which 
  

   were 
  unknown 
  when 
  this 
  work 
  first 
  made 
  its 
  appearance. 
  

  

  It 
  may 
  be 
  permitted 
  me 
  to 
  indicate 
  here, 
  for 
  the 
  benefit 
  

   of 
  those 
  who 
  may 
  desire 
  to 
  pursue 
  the 
  study 
  further 
  than 
  

   the 
  present 
  volume 
  will 
  carry 
  them, 
  where 
  they 
  may 
  find 
  

  

  C_r>the 
  assistance 
  they 
  require 
  for 
  such 
  an 
  extension. 
  In 
  the 
  

   .-'first 
  place 
  the 
  general 
  structure, 
  relations, 
  affinities, 
  and 
  

  

  * 
  — 
  differences 
  of 
  the 
  principal 
  groups 
  are 
  treated 
  much 
  more 
  

  

  ' 
  fully 
  and 
  completely 
  than 
  they 
  could 
  be 
  in 
  a 
  work 
  such 
  

  

  as 
  the 
  present 
  in 
  a 
  volume 
  entitled 
  ' 
  Fungi, 
  their 
  Nature, 
  

  

  Uses, 
  Influences, 
  &c.,' 
  written 
  by 
  me
