  Xylaria

  Acer 
  saccharinum.

  This 
  species 
  is 
  quite 
  variable. 
  Specimens 
  growing 
  in 
  the 
  same 
  

   group 
  and 
  under 
  the 
  same 
  conditions 
  had 
  the 
  stroma 
  terete 
  or 
  com- 
  

   pressed, 
  simple 
  or 
  divided 
  above 
  into 
  two 
  or 
  more 
  branches, 
  or 
  two 
  

   or 
  more 
  would 
  be 
  united 
  at 
  the 
  base 
  only 
  as 
  if 
  growing 
  from 
  a 
  single 
  

   starting 
  point. 
  Occasionally 
  two 
  clubs 
  are 
  confluent 
  or 
  grown 
  

   together 
  throughout 
  their 
  entire 
  length. 
  The 
  apex 
  may 
  be 
  either 
  

   rather 
  bluntly 
  acute 
  or 
  acuminate 
  and 
  sterile, 
  but 
  sometimes 
  it 
  is 
  

   obtuse. 
  The 
  stem 
  may 
  be 
  either 
  short 
  or 
  long 
  and 
  wholly 
  glabrous 
  

   or 
  at 
  the 
  very 
  base 
  involved 
  in 
  mucedinous 
  tomentum. 
  The 
  clubs 
  in 
  

   our 
  specimens 
  were 
  very 
  fragile 
  when 
  fresh. 
  

  

  Var. 
  tenuis 
  n. 
  var. 
  Clubs 
  slender, 
  i 
  to 
  1.5 
  lines 
  thick, 
  with 
  the 
  

   sterile 
  apex 
  commonly 
  more 
  conspicuous; 
  perithecia 
  less 
  crowded 
  

   and 
  more 
  prominent 
  ; 
  stem 
  elongated, 
  commonly 
  flexuous. 
  

  

  This 
  variety 
  was 
  found 
  growing 
  on 
  the 
  same 
  trunk 
  with 
  the 
  ordi- 
  

   nary 
  form 
  but 
  lower 
  down 
  on 
  the 
  sides 
  and 
  partly 
  beneath, 
  and 
  

   probably 
  depends 
  chiefly 
  on 
  its 
  place 
  of 
  growth 
  for 
  its 
  peculiar 
  devel- 
  

   opment. 
  The 
  spores 
  both 
  in 
  it 
  and 
  in 
  the 
  typical 
  form 
  are 
  .0007 
  to 
  

   ,0009 
  in. 
  long. 
  

  

  Var. 
  Americana 
  diflfers 
  chiefly 
  in 
  its 
  shorter 
  spores, 
  which 
  are 
  about 
  

   ,0005 
  in. 
  long. 
  This 
  is 
  our 
  most 
  common 
  form 
  and 
  the 
  dimensions 
  

   of 
  its 
  spores 
  are 
  given 
  in 
  the 
  work 
  on 
  North 
  American 
  Pyrenomy- 
  

   cetes 
  as 
  representing 
  the 
  spores 
  of 
  the 
  species 
  in 
  this 
  country. 
  It 
  

   may 
  be 
  a 
  question 
  whether 
  this 
  fungus 
  would 
  better 
  be 
  considered 
  a 
  

   variety 
  of 
  X. 
  digitata 
  or 
  a 
  distinct 
  species.

  NEW 
  YORK 
  SPECIES 
  OF 
  FLAMMULA. 
  

  

  Flammula 
  J^r. 
  

  

  Pileus 
  fleshy, 
  its 
  margin 
  at 
  first 
  involute; 
  lamellae 
  decurrent 
  or 
  

  

  adnate 
  without 
  a 
  sinus; 
  stem 
  fleshy-fibrous, 
  not 
  mealy 
  on 
  the 
  upper 
  

  

  part; 
  veil 
  fibrillose 
  or 
  none. 
  

  

  The 
  genus 
  Flammula 
  is 
  not 
  represented 
  in 
  our 
  territory 
  by 
  a 
  large 
  

   number 
  of 
  species. 
  It 
  is, 
  nevertheless, 
  not 
  very 
  sharply 
  distinct 
  from
