  subrotund 
  or

   ameter, 
  erumpent, 
  penetrating 
  the 
  wood, 
  generally 
  with 
  a 
  

   thin 
  black 
  crust 
  beneath 
  and 
  around 
  them, 
  the 
  disk 
  convex 
  

   or 
  slightly 
  depressed, 
  rough, 
  brown 
  or 
  black, 
  sometimes 
  

   whitish-pulverulent; 
  perithecia 
  crowded, 
  deeply 
  imbedded 
  

   in

  elongated 
  ; 
  ostiola

  asci 
  short,

  crowded, 
  elliptical, 
  simple, 
  often

  The 
  pustules 
  sometimes 
  appear 
  in 
  long 
  lines 
  or 
  series. 
  

   The 
  peculiar 
  and 
  anomalous 
  character 
  of 
  this 
  species 
  is 
  

   found 
  in 
  its 
  unusual 
  spores 
  and 
  in 
  its 
  attacking 
  living 
  stems. 
  

  

  Melaistcoets 
  bicornis 
  Cootie. 
  

  

  Perithecia 
  circinating, 
  five 
  to 
  seven, 
  seated 
  beneath 
  the 
  

   epidermis 
  which 
  is 
  but 
  slightly 
  elevated 
  ; 
  ostiola 
  short, 
  con- 
  

   vergent, 
  just 
  piercing 
  the 
  epidermis, 
  with 
  a 
  regular 
  orifice 
  ; 
  

   spores 
  expelled 
  when 
  mature, 
  blackening 
  the 
  matrix 
  round 
  

   the 
  ostiola, 
  fasciculate, 
  obtusely 
  fusiform, 
  straight 
  or 
  curved, 
  

   triseptate, 
  brown, 
  .0026

  -.0033 
  / 
  long, 
  scarcely 
  constricted, 
  

   ultimate 
  cells 
  smallest, 
  each 
  extremity 
  tapering 
  into 
  a 
  hya- 
  

   line 
  at 
  first 
  straight 
  then 
  curved 
  or 
  flexuous 
  cornute 
  append- 
  

   age, 
  one-half 
  to 
  one-third 
  the
