  The 
  species 
  of 
  this 
  genus 
  are 
  related 
  to 
  the 
  Agarici 
  on 
  one 
  hand, 
  

   and 
  to 
  the 
  Boleti 
  on 
  the 
  other. 
  The 
  important 
  distinguishing 
  char- 
  

   acter 
  is 
  afforded 
  by 
  the 
  lamellae, 
  which 
  are 
  easily 
  and 
  smoothly 
  sep- 
  

   arable 
  from 
  the 
  pileus, 
  just 
  as 
  the 
  tubes 
  of 
  a 
  Boletus 
  are 
  from 
  the 
  

   pilous 
  that 
  supports 
  them. 
  This 
  relationship 
  between 
  thePaxilli 
  and 
  

   Boleti 
  is 
  still 
  further 
  indicated 
  by 
  the 
  anastomosing 
  of 
  the 
  lamellae, 
  

   which 
  in 
  one 
  species, 
  Paxillus 
  ptorosus. 
  is 
  carried 
  to 
  such 
  an 
  extent 
  

   that 
  the 
  hymenium 
  is 
  as 
  distinctly 
  porous 
  as 
  it 
  is 
  in 
  some 
  Boleti. 
  On 
  

   the 
  other 
  hand, 
  the 
  close 
  relationship 
  that 
  exists 
  between 
  this 
  genus 
  

   and 
  the 
  genus 
  Agaricus 
  may 
  be 
  inferred 
  from 
  the 
  fact 
  that 
  Agaricus 
  

   personatus 
  and 
  A. 
  cinerascens 
  are 
  still 
  retained 
  by 
  Fries 
  among 
  the 
  

   Agarici, 
  although 
  he 
  makes 
  the 
  remark 
  that 
  they 
  belong 
  rather 
  to 
  

   the 
  Paxilli. 
  In 
  the 
  second 
  edition 
  of 
  Epicrisis 
  he 
  has 
  modified 
  the 
  

   diagnosis 
  of 
  the 
  genus, 
  and 
  at 
  the 
  same 
  time 
  admitted 
  that 
  it 
  is 
  " 
  not 
  

   yet 
  correctly 
  defined." 
  Neither 
  is 
  the 
  limitation 
  of 
  the 
  two 
  tribes 
  

   into 
  which 
  he 
  divides 
  the 
  species 
  very 
  satisfactory, 
  for 
  a 
  central 
  stem 
  

   and 
  sordid 
  spores, 
  characters 
  assigned 
  to 
  Lepista, 
  are 
  not 
  always 
  

   associated 
  together, 
  nor 
  are 
  ferruginous 
  spores 
  found 
  only 
  in 
  species 
  

   with 
  the 
  stem 
  commonly 
  lateral 
  or 
  eccentric. 
  It 
  has, 
  therefore, 
  

   seemed 
  best 
  to 
  me, 
  for 
  the 
  present, 
  to 
  refer 
  to 
  this 
  genus 
  such 
  species 
  

   only 
  as 
  have 
  the 
  spores 
  colored 
  and 
  the 
  separable 
  lamellae 
  more 
  or 
  

   less 
  branched, 
  crisped 
  or 
  anastomosing. 
  This 
  reduces 
  our 
  species 
  to 
  

   five, 
  three 
  of 
  which 
  are 
  found 
  also 
  in 
  Europe. 
  They 
  grow 
  chiefly 
  

   in 
  woods 
  and 
  occur 
  in 
  the 
  latter 
  part 
  of 
  summer 
  and 
  in 
  autumn. 
  

   The 
  separable 
  character 
  of 
  the 
  hymenium 
  can 
  only 
  be 
  ascertained 
  by 
  

   the 
  mutilation 
  of 
  a 
  specimen.
