  but 
  when 
  growing 
  upon 
  small 
  trunks 
  or 
  branches, 
  which 
  seem 
  

   to 
  be 
  a 
  favorite 
  habitat, 
  and 
  which 
  it 
  partly 
  surrounds 
  or 
  clasps 
  

   by 
  its 
  base, 
  it 
  becomes 
  somewhat 
  reniform. 
  Sometimes 
  it 
  is 
  

   quite 
  orbicular, 
  in 
  which 
  case 
  it 
  usually 
  occurs 
  on 
  the 
  under 
  

   side 
  of 
  a 
  branch 
  to 
  which 
  it 
  is 
  attached 
  by 
  its 
  vertex, 
  or 
  on 
  the 
  

   upper 
  side 
  to 
  which 
  it 
  is 
  attached 
  by 
  an 
  eccentric 
  or 
  the 
  central 
  

   point 
  of 
  the 
  hymenium. 
  It 
  is 
  normally 
  and 
  repeatedly 
  zonate 
  

   and 
  more 
  or 
  less 
  sulcate, 
  with 
  the 
  zones 
  usually 
  quite 
  narrow 
  

   and 
  not 
  differing 
  very 
  much 
  in 
  color 
  from 
  the 
  general 
  hue 
  of 
  

   the 
  pileus. 
  Slight 
  radiating 
  rugae 
  or 
  elevations 
  are 
  generally 
  

   present, 
  and 
  these, 
  in 
  passing 
  over 
  the 
  furrows, 
  sometimes 
  ren- 
  

   der 
  the 
  surface 
  rough 
  or 
  scabrous. 
  This 
  roughness 
  is 
  occasion- 
  

   ally 
  increased 
  to 
  such 
  an 
  extent 
  that 
  the 
  surface 
  becomes 
  very 
  

   uneven, 
  especially 
  toward 
  the 
  base. 
  Not 
  very 
  rarely 
  a 
  kind 
  of 
  

   tough 
  appressed 
  and 
  at 
  length 
  hardened 
  and 
  giabrated 
  tomen- 
  

   tum 
  overspreads 
  a 
  part 
  or 
  the 
  whole 
  of 
  the 
  pileus 
  and 
  thus 
  con- 
  

   ceals 
  to 
  a 
  greater 
  or 
  less 
  extent 
  the 
  zones 
  and 
  radiations. 
  This 
  

   coating 
  can 
  sometimes 
  be 
  separated 
  from 
  the 
  pileus 
  in 
  scales 
  or 
  

   flakes 
  like 
  a 
  kind 
  of 
  crust. 
  It 
  is 
  most 
  often 
  limited 
  to 
  the 
  basal 
  

   or 
  central 
  portions 
  of 
  the 
  pileus. 
  Its 
  unequal 
  distribution 
  gives 
  

   a 
  rough 
  and 
  unnatural 
  appearance 
  to 
  the 
  plant. 
  In 
  some 
  speci- 
  

   mens 
  the 
  pileus 
  is 
  dull 
  and 
  opaque, 
  in 
  others 
  it 
  is 
  smooth 
  and 
  

   shining. 
  In 
  size 
  it 
  occurs 
  from 
  half 
  an 
  inch 
  to 
  three 
  and 
  a 
  half 
  

   inches 
  in 
  diameter. 
  The 
  substance 
  is 
  usually 
  rather 
  thin, 
  

   sometimes 
  much 
  thinner 
  than 
  the 
  hymenium. 
  The 
  upper 
  

   surface 
  is 
  plane 
  or 
  slightly 
  convex, 
  though 
  specimens 
  are 
  not 
  

   wanting 
  in 
  which 
  the 
  pileus 
  is 
  much 
  thickened 
  behind 
  so 
  that 
  

   it 
  approaches 
  an 
  ungulate 
  form. 
  I 
  have 
  seen 
  it 
  in 
  different 
  

   individuals 
  both 
  umbonate 
  and 
  depressed 
  at 
  the 
  base, 
  but 
  these 
  

   are 
  rare 
  and 
  exceptional 
  forms. 
  In 
  color 
  there 
  is 
  considerable 
  

   diversity, 
  some 
  specimens 
  being 
  whitish, 
  or 
  gray, 
  others 
  having 
  

   a 
  dark 
  reddish-brown 
  or 
  chestnut 
  color. 
  Between 
  these 
  ex- 
  

   tremes 
  there 
  is 
  a 
  great 
  variety 
  of 
  intermediate 
  hues, 
  but 
  a 
  kind 
  

   of 
  pallid 
  wood-color, 
  more 
  or 
  less 
  tinged 
  with 
  rufous 
  or 
  cervine 
  

   hues, 
  prevails. 
  The 
  thin 
  margin 
  is 
  usually 
  concolorous, 
  but 
  

   sometimes 
  in 
  pale 
  specimens 
  it 
  is 
  more 
  highly 
  colored 
  than 
  the 
  

   rest. 
  Occasionally 
  the 
  whole 
  plant 
  assumes 
  a 
  ruddy 
  hue 
  in 
  

   drying. 
  The 
  substance 
  has 
  a 
  color 
  similar 
  to 
  that 
  of 
  the 
  surface 
  

   of 
  the 
  pileus, 
  but 
  in 
  dark 
  specimens 
  it 
  is 
  a 
  little 
  paler. 
  

  

  The 
  hymenium 
  varies 
  if 
  possible 
  more 
  than 
  the 
  hymenophore. 
  

   There 
  are 
  four 
  typical 
  forms 
  which 
  for 
  convenience 
  may 
  be 
  

   called 
  lenzitoid, 
  dcedaleoid, 
  trametoid 
  and 
  polyporoid. 
  In 
  the 
  

   first 
  the 
  dissepiments 
  are 
  lamellae, 
  here 
  and 
  there 
  forked 
  or 
  

   dichotomouslyhranched 
  and 
  sometimes 
  slightly 
  anastomosing, 
  

   especially 
  at 
  the 
  base. 
  Such 
  specimens 
  would 
  be 
  referred 
  to 
  

   Lenzites. 
  In 
  the 
  second 
  the 
  pores 
  are 
  unequal, 
  some 
  of 
  them 
  

   elongated 
  and 
  flexuous 
  or 
  labyrinthiform. 
  Such 
  specimens 
  

   belong 
  to 
  Dcedalea. 
  In 
  the 
  third, 
  rotund 
  and 
  straight 
  elongated 
  

   pores 
  are 
  intermingled 
  and 
  generally 
  arranged 
  in 
  a 
  radiating 
  

   manner. 
  These 
  belong 
  to 
  Trametes. 
  In 
  the 
  fourth 
  the 
  pores
