  our 
  plant. 
  The 
  threads 
  of 
  the 
  subiculum 
  are 
  obscurely 
  septate 
  and 
  

   sometimes 
  slightly 
  branched. 
  The 
  more 
  classical 
  name 
  " 
  leucostoma 
  " 
  

   is 
  here 
  substituted 
  for 
  "albidostoina." 
  

  

  Zigiioella 
  lmmulina. 
  

  

  Perithecia 
  small, 
  .011 
  to 
  .014 
  in. 
  broad, 
  depressed-hemispherical, 
  

   slightly 
  sunk 
  in 
  the 
  matrix, 
  subglabrous, 
  black, 
  with 
  a 
  minute 
  papil- 
  

   late 
  ostiolum 
  ; 
  asci 
  cylindrical, 
  .0025 
  to 
  .003 
  in. 
  long, 
  .0003 
  to 
  .0004 
  

   in. 
  broad 
  ; 
  spores 
  uniseriate 
  or 
  obliquely 
  monostichous, 
  elliptical, 
  

   four-locular, 
  appearing 
  obscurely 
  triseptate, 
  colorless, 
  .0005 
  to 
  .0006 
  

   in. 
  long, 
  .00025 
  to

  The 
  spores 
  are 
  not 
  distinctly 
  triseptate, 
  and 
  the 
  species 
  apparently 
  

   belongs 
  to 
  the 
  subgenus 
  Zignoina. 
  The 
  perithecia 
  have 
  a 
  dull, 
  

   squalid, 
  unpolished 
  or 
  subscabrous 
  appearance. 
  

  

  Acrosperinuin 
  album. 
  

  

  Perithecia 
  elongated, 
  subfusiform, 
  somewhat 
  compressed, 
  pointed 
  

   at 
  the 
  apex, 
  narrowed 
  below 
  into 
  a 
  short, 
  terete, 
  stem-like 
  base, 
  

   white 
  ; 
  spores 
  very 
  long, 
  filiform.

  This 
  resembles 
  A. 
  compressum 
  in 
  size, 
  but 
  it 
  is 
  at 
  once 
  distinguished 
  

   from 
  that 
  and 
  other 
  related 
  species 
  by 
  its 
  persistently 
  white 
  color.
