  Maple

   This 
  species 
  is 
  apparently 
  allied 
  to 
  H. 
  LascMi 
  Nke., 
  and 
  

   approaches 
  in 
  some 
  respects 
  species 
  of 
  Nummularia.

  I 
  fail 
  to 
  see 
  why 
  Schweinitz 
  referred 
  this 
  fungus 
  to 
  the 
  

   genus 
  Hysterium 
  since 
  there 
  is 
  no 
  chink 
  or 
  linear 
  opening 
  in 
  

   any 
  of 
  the 
  specimens 
  that 
  have 
  come 
  under 
  my 
  inspection.

  Stroma 
  small, 
  slightly 
  prominent, 
  scattered 
  or 
  subconfluent, 
  

   often 
  irregular, 
  carbonaceous, 
  black 
  ; 
  nuclei 
  numerous, 
  white 
  

   within 
  ; 
  spores 
  crowded 
  or 
  biseriate, 
  lanceolate 
  or 
  subfusiform, 
  

   colorless,

   The 
  spores 
  may 
  possibly 
  be 
  uniseptate 
  when 
  fully 
  mature. 
  

   Those 
  examined 
  are 
  not 
  clearly 
  septate.

  Authors 
  do 
  not 
  all 
  agree 
  in 
  the 
  characters 
  they 
  ascribe 
  to 
  the 
  

   spores 
  of 
  Dothidea 
  filicina, 
  one 
  describing 
  them 
  as 
  " 
  elliptical 
  

   uniseptate," 
  another 
  as 
  " 
  triseptate." 
  Neither 
  of 
  these 
  descrip- 
  

   tions 
  will 
  apply 
  to 
  the 
  spores 
  of 
  the 
  species 
  just 
  characterized. 
  

   The 
  Dothidea 
  which 
  I 
  find 
  on 
  Pteris 
  aquilina, 
  the 
  habitat 
  

   assigned 
  to 
  D. 
  ftlicina, 
  has 
  the 
  spores 
  triseptate.
