  Spots 
  mostly 
  suborbicular, 
  convex 
  above, 
  concave 
  below, 
  some- 
  

   times 
  confluent 
  and 
  irregular, 
  discolored, 
  either 
  paler 
  or 
  darker 
  than 
  

   the 
  surrounding 
  tissues; 
  asci 
  epiphyllous, 
  subcylindric, 
  sometimes 
  

   a 
  little 
  contracted 
  just 
  above 
  the 
  basal 
  cell, 
  .0016 
  to 
  .002

   .0005

  the 
  stalk 
  cell 
  .0005 
  to

  in. 
  broad 
  and 
  

   nearly 
  as

  spores 
  commonly 
  8, 
  globose 
  or 
  broadly

   .00024

  This 
  species 
  is 
  allied 
  to 
  Exoascus 
  deformans, 
  from 
  which 
  it 
  may 
  

   be 
  distinguished 
  by 
  its 
  rather 
  larger 
  asci 
  and 
  spores 
  and 
  by 
  its 
  

   general 
  habit. 
  The 
  invaded 
  leaves 
  are 
  less 
  distorted, 
  even 
  when 
  the 
  

   spots 
  are 
  large 
  and 
  occupy 
  much 
  of 
  their 
  surface, 
  and 
  the 
  fungus, 
  

   so 
  far 
  as 
  I 
  have 
  seen, 
  occupies 
  the 
  upper 
  surface 
  only. 
  This 
  at 
  

   length 
  becomes 
  slightly 
  whitened 
  by 
  the 
  effusion 
  of 
  the 
  spores. 
  

   Generally 
  there 
  are 
  from 
  one 
  to 
  three 
  spots 
  on 
  a 
  leaf.

  in 
  an 
  orange 
  colored 
  to- 
  

   mentum, 
  orange 
  colored, 
  the 
  ostiola 
  slightly 
  darker;

  slender, 
  

   cylindric, 
  .0025 
  to 
  .003

  This 
  fungus 
  appears 
  to 
  have 
  been 
  included 
  by 
  Mr 
  Ellis 
  in 
  Hy- 
  

   pocrea 
  pallida, 
  with 
  which 
  it 
  agrees 
  in 
  spore 
  characters, 
  but 
  from 
  

   which 
  it 
  differs 
  so 
  greatly 
  in 
  its 
  formation 
  of 
  a 
  continuous 
  crust 
  and 
  

   in 
  the 
  orange 
  color 
  of 
  the 
  perithecia 
  and 
  tomentum 
  that 
  it 
  seems 
  to 
  

   me 
  to 
  merit 
  separation 
  as 
  a 
  distinct 
  species.
