  Agaric 
  us

  Fr. 
  

  

  In 
  the 
  new 
  edition 
  of 
  Epicrisis 
  this 
  species 
  is 
  described 
  as 
  having 
  

   globose 
  spores 
  ; 
  it 
  therefore 
  becomes 
  necessary 
  to 
  regard 
  as 
  a 
  distinct 
  

   species 
  the 
  plant 
  reported 
  under 
  this 
  name 
  in 
  the 
  23d 
  Report, 
  p. 
  72. 
  

   I 
  propose 
  for 
  it 
  the 
  name 
  Agaricus 
  (Lepiota) 
  naucinoides, 
  and 
  add 
  

   to 
  the 
  description 
  already 
  given 
  the 
  following 
  : 
  Spores 
  subelliptical, 
  

   .0003 
  -.00035' 
  long, 
  .0002 
  -.00025' 
  broad, 
  generally 
  with 
  a 
  single 
  large 
  

   nucleus. 
  

  

  The 
  difference 
  in 
  the 
  spores, 
  the 
  smoother 
  pileus 
  and 
  absence 
  of 
  

   an 
  umbo 
  will 
  separate 
  this 
  from 
  A. 
  naucinus. 
  

  

  There 
  is 
  also 
  another 
  closely 
  related 
  species, 
  A. 
  Schulzeri 
  Kalchb., 
  

   which 
  is 
  said 
  to 
  have 
  ovate 
  spores, 
  a 
  small 
  annulus, 
  an 
  umbonate 
  

   pileus 
  and 
  a 
  nauseous 
  taste, 
  characters 
  by 
  which 
  it 
  may 
  be 
  readily 
  

   distinguished 
  from 
  our 
  plant. 
  A. 
  IcBvis 
  Krombh., 
  and 
  A. 
  cretaoeus 
  

   Fr., 
  are 
  also 
  liable 
  to 
  be 
  confused 
  with 
  this 
  plant 
  if 
  the 
  spores 
  be 
  

   neglected, 
  the 
  former 
  being 
  distinguished 
  by 
  its 
  rosy 
  or 
  flesh-colored 
  

   spores, 
  the 
  latter 
  by 
  its 
  brown 
  spores. 
  Thus 
  it 
  appears 
  that 
  there 
  

   are 
  five 
  species 
  that 
  are 
  not 
  easily 
  separated 
  except 
  by 
  their 
  spore 
  

   characters 
  ; 
  a 
  strong 
  indication 
  of 
  the 
  importance 
  of 
  publishing 
  these 
  

   characters 
  with 
  the 
  descriptions 
  of 
  species.

  This 
  name 
  being 
  preoccupied 
  is 
  changed 
  to 
  Agaricus 
  magnive- 
  

   laris 
  Pk. 
  

  

  Agaricus 
  coprinoides 
  Pk. 
  Report

  This 
  name 
  also 
  has 
  been 
  applied 
  to 
  a 
  European 
  species 
  and 
  I 
  

   would 
  therefore 
  name 
  the 
  American 
  plant 
  Agaricus 
  plicatellus 
  Pk. 
  

  

  Agaricus 
  lilacinus 
  Pk. 
  Report 
  24, 
  p. 
  63. 
  

  

  This, 
  too, 
  is 
  applied 
  in 
  Europe 
  to 
  a 
  different 
  species. 
  I 
  would 
  

   therefore 
  substitute 
  for 
  it 
  the 
  more 
  appropriate 
  one, 
  Agaricus 
  lilaci- 
  

   folivs 
  Pk.

  In 
  the 
  first 
  edition 
  of 
  Epicrisis 
  the 
  genus 
  Trogia 
  is 
  limited 
  to 
  

   coriaceous 
  Agaricini 
  having 
  the 
  lamellae 
  or 
  folds 
  longitudinally 
  

   channelled 
  on 
  the 
  edge. 
  In 
  the. 
  Handbook 
  of 
  British 
  Fungi 
  the 
  

   generic 
  character 
  of 
  Trogia 
  is 
  so 
  modified 
  as 
  to 
  include 
  species 
  with 
  

   crisped 
  lamellae, 
  and 
  Cantharellus 
  crispus 
  is 
  referred 
  to 
  this 
  genus. 
  

   Also, 
  in 
  the 
  second 
  edition 
  of 
  Epicrisis 
  the 
  phrase 
  "in 
  spec. 
  Europsea 
  

   modo 
  crispae" 
  is 
  parenthetically 
  inserted 
  in 
  the 
  generic 
  description 
  

   of 
  Trogia 
  and 
  C. 
  crispus 
  becomes 
  Trogia 
  crispa. 
  If 
  this 
  classifica- 
  

   tion 
  is 
  to 
  be 
  adopted 
  and 
  followed 
  then 
  Plicatura 
  Alni 
  must 
  be 
  

   changed 
  to 
  Trogia 
  Alni. 
  The 
  reasons 
  for 
  its 
  adoption 
  are 
  twofold. 
  

   First 
  it 
  is 
  the 
  arrangement 
  of 
  the 
  venerable 
  Fries, 
  the 
  life-long 
  student 
  

   of 
  fungi, 
  who 
  probably 
  has 
  no 
  equal 
  in 
  the 
  knowledge 
  of 
  the 
  Agaricini
