﻿REPORT 
  OF 
  THE 
  STATE 
  BOTANIST 
  II3 
  

  

  Decorticated 
  wood 
  of 
  spruce, 
  Picea 
  Mariana. 
  Adirondack 
  moun- 
  

   tains. 
  September. 
  

  

  This 
  fungus 
  forms 
  patches 
  several 
  inches 
  in 
  extent. 
  In 
  external 
  

   appearance 
  it 
  is 
  suggestive 
  of 
  H. 
  Artocreas, 
  but 
  it 
  is 
  much 
  thinner, 
  

   with 
  shorter, 
  more 
  compressed 
  and 
  serrate 
  teeth. 
  This 
  last 
  character 
  

   will 
  also 
  separate 
  the 
  species 
  from 
  H. 
  fasciculare. 
  

  

  Hydnochaete

  gen. 
  

  

  Subiculum 
  effused, 
  submembranous, 
  fioccose-tomentose, 
  setige- 
  

   rous; 
  aculei 
  subulate, 
  setigerous. 
  

  

  A 
  hydnoid 
  genus 
  of 
  which 
  the 
  typical 
  species 
  is 
  like 
  a 
  resupinate 
  

   Hydnum 
  or 
  more 
  nearly 
  like 
  Caldesiella 
  ferruginosa, 
  but 
  it 
  differs 
  in 
  

   having 
  its 
  hymenium 
  furnished 
  with 
  small 
  smooth 
  colored 
  setae, 
  

   which 
  gives 
  to 
  the 
  Hydnei 
  a 
  genus 
  corresponding 
  to 
  Hymenochsete 
  

   among 
  the 
  Thelephorei 
  and 
  to 
  Mucronoporus 
  among 
  the 
  Polyporei. 
  

  

  Hydnochaete 
  setigera 
  n. 
  sp. 
  

  

  Subiculum 
  thin, 
  at 
  first 
  grayish-tawny 
  or 
  pale 
  tawny, 
  tomentulose, 
  

   setigerous, 
  the 
  margin 
  even 
  and 
  concolorous 
  or 
  sometimes 
  somewhat 
  

   fimbriate 
  and 
  whitish 
  or 
  grayish-white 
  ; 
  aculei 
  at 
  first 
  short, 
  subcorn- 
  

   eal, 
  blunt, 
  pale 
  tawny, 
  becoming 
  subulate 
  with 
  age, 
  about 
  one 
  line 
  

   long, 
  villosely 
  setigerous, 
  persisting 
  through 
  the 
  winter 
  and 
  becom- 
  

   ing 
  ferruginous 
  or 
  dark 
  ferruginous, 
  the 
  plant 
  becoming 
  stratose 
  by 
  

   the 
  development 
  of 
  a 
  new 
  subiculum 
  and 
  new 
  aculei 
  over 
  the 
  old 
  

   ones 
  each 
  year, 
  the 
  setae 
  simple 
  or 
  branched, 
  .0016 
  to 
  .0024 
  in. 
  long, 
  

   slender, 
  sharp 
  pointed 
  ; 
  spores 
  pale, 
  subglobose 
  or 
  broadly 
  elliptical,, 
  

   .0002 
  to 
  .0003 
  in. 
  long. 
  

  

  Decaying 
  wood 
  of 
  pine, 
  spruce 
  and 
  hemlock. 
  Adirondack 
  moun- 
  

   tains. 
  July 
  to 
  September. 
  I 
  have 
  also 
  received 
  specimens 
  of 
  the 
  first 
  

   year's 
  growth 
  of 
  this 
  fungus 
  from 
  Professor 
  Underwood, 
  who 
  col- 
  

   lected 
  them 
  on 
  the 
  White 
  mountains. 
  

  

  Although 
  forming 
  strata, 
  this 
  species 
  must 
  be 
  very 
  distinct 
  from 
  

   the 
  plant 
  described 
  by 
  Rev. 
  M. 
  J. 
  Berkeley 
  under 
  the 
  name 
  Hydnum 
  

   stratosum. 
  In 
  its 
  first 
  year 
  it 
  is 
  so 
  similar 
  in 
  general 
  appearance 
  to 
  

   Caldesiella 
  ferruginosa 
  Sacc, 
  (Hydnum 
  ferruginosum 
  Fr.) 
  that 
  by 
  a 
  

   careless 
  observer 
  it 
  might 
  easily 
  be 
  mistaken 
  for 
  it, 
  but 
  its 
  paler 
  color 
  

   and 
  the 
  presence 
  of 
  set^ 
  will 
  at 
  once 
  separate 
  it.
