  As 
  soon 
  as 
  the 
  characters 
  of 
  this 
  species 
  were 
  published 
  by 
  Rev. 
  

   M. 
  J. 
  Berkeley, 
  it 
  became 
  evident 
  that 
  the 
  plant 
  I 
  had 
  hesitatingly 
  

   referred 
  to 
  it 
  and 
  described 
  in 
  the 
  location 
  cited 
  was 
  distinct. 
  There 
  

   is 
  no 
  pulverulence 
  to 
  our 
  plant 
  nor 
  does 
  it 
  have 
  " 
  pilei 
  arising 
  from 
  

   a 
  common 
  base." 
  I 
  would, 
  therefore, 
  give 
  it 
  the 
  name 
  Boletus 
  orna- 
  

   tipes. 
  Either 
  this 
  or 
  a 
  closely 
  related 
  form 
  is 
  regarded 
  by 
  my 
  friend, 
  

   Mr. 
  C. 
  0. 
  Frost, 
  as 
  a 
  variety 
  of 
  B. 
  griseus, 
  but 
  the 
  yellow 
  flesh 
  and 
  

   the 
  tubes, 
  which 
  are 
  also 
  yellow 
  from 
  the 
  first, 
  indicate 
  to 
  my 
  mind 
  

   a 
  specific 
  difference. 
  It 
  is 
  by 
  having 
  respect 
  to 
  such 
  a 
  difference 
  in 
  

   color 
  that 
  the 
  whole 
  genus 
  has 
  been 
  divided 
  into 
  primary 
  series, 
  and 
  

   it 
  hardly 
  seems 
  fitting 
  to 
  throw 
  together, 
  as 
  varieties 
  of 
  one 
  species, 
  

   forms 
  thus 
  separated. 
  

  

  Thelephoea

  This 
  name, 
  being 
  preoccupied, 
  must 
  be 
  changed. 
  I 
  would 
  substi- 
  

   tute 
  for 
  it, 
  Thelephora 
  Schweinitzii.

  Since 
  the 
  publication 
  of 
  this 
  species, 
  for 
  the 
  authenticity 
  of 
  which 
  

   I 
  depended 
  upon 
  specimens 
  received 
  from 
  the 
  late 
  Dr. 
  Curtis, 
  Rev. 
  

   Dr. 
  Berkeley 
  has 
  published 
  in 
  Grevillea, 
  1874, 
  p. 
  53, 
  under 
  the 
  same 
  

   name, 
  a 
  species 
  which 
  is 
  clearly 
  quite 
  different. 
  He 
  also 
  finds 
  Pucci- 
  

   nia 
  Saxifragarum 
  on 
  Tiarella 
  leaves. 
  Neither 
  can 
  this 
  be 
  our 
  plant, 
  

   for 
  P. 
  Saxifragarum 
  has 
  its 
  spores 
  much 
  broader 
  and 
  more 
  obtuse. 
  

   In 
  view, 
  therefore, 
  of 
  the 
  peculiar 
  circumstances 
  attending 
  the 
  publi- 
  

   cation 
  of 
  these 
  two 
  species 
  under 
  the 
  same 
  name, 
  I 
  deem 
  it 
  the 
  most 
  

   courteous, 
  if 
  not 
  the 
  most 
  correct 
  way, 
  to 
  drop 
  the 
  name 
  P. 
  Tiarellm 
  

   from 
  its 
  connection 
  with 
  the 
  plant 
  described 
  in 
  the 
  25th 
  Report, 
  and 
  

   substitute 
  for 
  it 
  the 
  name 
  Puccinia 
  spreta 
  Pk., 
  thus 
  leaving 
  P. 
  

   Tiarellm 
  B. 
  & 
  C. 
  for 
  the 
  species 
  to 
  which 
  it 
  has 
  been 
  applied 
  by 
  Dr. 
  

   Berkeley.

  Some 
  account 
  of 
  the 
  synonymy 
  of 
  this 
  species 
  seems 
  desirable. 
  In 
  

   the 
  synopsis 
  of 
  the 
  Fungi 
  of 
  North 
  Carolina, 
  Dr. 
  Schweinitz 
  describes 
  

   a 
  fungus 
  under 
  the 
  name 
  Tlredo 
  Oaladii, 
  giving 
  Caladium 
  as 
  its 
  

   habitat. 
  In 
  his 
  Synopsis 
  of 
  North 
  American 
  Fungi, 
  he 
  changes 
  the 
  

   name 
  of 
  this 
  fungus 
  to 
  Tlredo 
  Ari- 
  Virginici, 
  adding 
  the 
  remark, 
  

   perhaps 
  as 
  a 
  reason 
  for 
  the 
  change, 
  " 
  it 
  is 
  not 
  Caladium 
  but 
  Arum 
  on 
  

   which 
  it 
  is 
  found 
  frequently." 
  This 
  remark 
  admits 
  of 
  two 
  interpre- 
  

   tations 
  depending 
  upon 
  the 
  stress 
  given 
  to 
  the 
  last 
  word. 
  He 
  may 
  

   have 
  found 
  the 
  fungus 
  at 
  first 
  on 
  Caladium 
  and 
  afterwards 
  more 
  fre- 
  

   quently 
  on 
  Arum, 
  or 
  he 
  may 
  at 
  first 
  have 
  mistaken 
  the 
  host 
  plant, 
  

   Arum, 
  for 
  Caladium, 
  in 
  which 
  case 
  the 
  remark 
  must 
  have 
  been
