  Decaying 
  wood 
  of 
  hemlock. 
  Adirondack 
  mountains. 
  August. 
  

  

  This 
  is 
  Sphceria 
  scopula 
  C. 
  & 
  P. 
  in 
  the 
  Thirty 
  -second 
  Report. 
  It 
  

   is 
  here 
  referred 
  to 
  the 
  genus 
  Acanthostigma 
  because 
  of 
  the 
  shape 
  of 
  

   the 
  spores. 
  From 
  A. 
  Clintonii 
  it 
  may 
  be 
  distinguished 
  by 
  its 
  larger 
  

   perithecia 
  and 
  longer 
  spores. 
  

  

  Lasiosphaeria 
  intricata. 
  

  

  Perithecia 
  scattered 
  or 
  crowded, 
  somewhat 
  elongated, 
  .025 
  to 
  .035 
  

   in. 
  long, 
  .018 
  to 
  .02 
  broad, 
  generally 
  narrowed 
  toward 
  the 
  base, 
  

   obtuse, 
  subfragile, 
  tomentose-hairy, 
  brown 
  or 
  blackish-brown 
  ; 
  subi- 
  

   culum 
  very 
  thin 
  or 
  none 
  ; 
  asci 
  slender, 
  elongated, 
  .005 
  to 
  .008 
  in. 
  

   long, 
  .0004 
  to 
  .0005 
  broad 
  ; 
  spores 
  crowded, 
  linear, 
  curved 
  or 
  flexu- 
  

   ous, 
  greenish-yellow, 
  .0016 
  to 
  .0025 
  in. 
  long, 
  .00016 
  to 
  .0002 
  broad. 
  

  

  Decaying 
  wood 
  and 
  leaves 
  in 
  damp 
  places. 
  Sandlake. 
  

  

  The 
  species 
  belongs 
  to 
  the 
  section 
  Leptospora. 
  The 
  perithecia, 
  

   though 
  small, 
  resemble 
  in 
  shape 
  those 
  of 
  Bombardia 
  fasciculata. 
  

   The 
  minute 
  papillate 
  ostiolum 
  is 
  often 
  concealed 
  by 
  the 
  tomentum 
  of 
  

   the 
  perithecia. 
  This 
  is 
  composed 
  of 
  intricate, 
  matted, 
  slender, 
  sep- 
  

   tate, 
  brown 
  filaments, 
  which, 
  by 
  their 
  soft, 
  tomentose 
  character, 
  read- 
  

   ily 
  distinguish 
  this 
  species 
  from 
  the 
  related 
  L. 
  strigosa, 
  L. 
  hispida, 
  

   L. 
  hirsuta, 
  etc. 
  

  

  Herpotricliia 
  leucostoma. 
  

  

  Perithecia 
  small, 
  .012 
  to 
  .018 
  in. 
  broad, 
  numerous, 
  somewhat 
  

   crowded, 
  subglobose, 
  seated 
  upon 
  or 
  involved 
  in 
  a 
  blackish-brown 
  

   tomentum, 
  the 
  ostiola 
  naked, 
  not 
  prominent, 
  whitish 
  when 
  moist, 
  

   grayish 
  or 
  sordid 
  when 
  dry 
  ; 
  asci 
  cylindrical 
  or 
  subclavate, 
  .006 
  to 
  

   .008 
  in. 
  long, 
  .0004 
  to 
  .0006 
  broad 
  ; 
  spores 
  crowded 
  or 
  biseriate, 
  

   oblong- 
  fusiform, 
  at 
  first 
  uniseptate, 
  constricted 
  at 
  the 
  septum 
  and 
  

   containing 
  two 
  or 
  three 
  nuclei 
  in 
  each 
  cell, 
  then 
  three 
  to 
  five-septate, 
  

   colorless, 
  .0015 
  to 
  .002 
  in. 
  long, 
  .0003 
  to 
  .00035 
  in. 
  broad. 
  

  

  Dead 
  branches 
  of 
  mountain 
  maple-bush, 
  Acer 
  spicatum. 
  Catskill 
  

   mountains. 
  September. 
  

  

  The 
  whitish 
  ostiola 
  constitute 
  a 
  marked 
  feature 
  in 
  this 
  species. 
  It 
  

   is 
  distinguished 
  from 
  Herpotrichia 
  Schiedermayeriana 
  Fckl. 
  by 
  its 
  

   much 
  smaller 
  perithecia, 
  and 
  the 
  more 
  numerous 
  septa 
  of 
  the 
  spores. 
  

   I 
  have 
  observed 
  no 
  globose 
  appendages 
  at 
  the 
  ends 
  of 
  the 
  spores 
  in
