﻿60 
  TWENTY-TSTNTH 
  REPOKT 
  ON 
  THE 
  STATE 
  MUSEUM. 
  

  

  is 
  at 
  first 
  olive-brown 
  in 
  color, 
  but 
  at 
  length 
  black 
  spots 
  appear 
  upon 
  

   it. 
  These 
  gradually 
  enlarge 
  until 
  the 
  whole 
  surface 
  becomes 
  black. 
  

   With 
  this 
  change 
  in 
  the 
  color 
  of 
  the 
  subiculum, 
  the 
  perithecia 
  appear, 
  

   but 
  they 
  do 
  not, 
  apparently, 
  perfect 
  their 
  spores 
  until 
  the 
  following 
  

   spring, 
  spore-bearing 
  specimens 
  having 
  been 
  found 
  in 
  May. 
  The 
  

   affected 
  leaves 
  adhere 
  to 
  the 
  branch 
  during 
  the 
  winter 
  and 
  the 
  early 
  

   part 
  of 
  the 
  following 
  summer. 
  These 
  dry 
  leaves, 
  when 
  seen 
  among 
  

   the 
  surrounding 
  green 
  leaves 
  that 
  put 
  forth 
  before 
  these 
  have 
  fallen, 
  

   together 
  with 
  the 
  drooping 
  branch 
  that 
  bears 
  them, 
  are 
  deceptively 
  

   imitative 
  of 
  dead 
  leaves 
  on 
  a 
  branch 
  that 
  has 
  been 
  broken 
  down 
  but 
  

   still 
  adheres 
  by 
  a 
  shred 
  to 
  the 
  parent 
  trunk. 
  The 
  young 
  fungus 
  

   commences 
  its 
  growth 
  before 
  the 
  old 
  one 
  of 
  the 
  previous 
  year 
  has 
  

   disappeared. 
  I 
  have 
  taken 
  from 
  the 
  same 
  tree, 
  at 
  the 
  same 
  time, 
  old 
  

   leaves 
  bearing 
  the 
  mature 
  Sphseria, 
  and 
  young 
  leaves 
  bearing 
  the 
  

   subiculum 
  and 
  young 
  perithecia 
  of 
  the 
  succeeding 
  crop. 
  The 
  fungus 
  

   does 
  not 
  appear 
  to 
  kill 
  the 
  branch 
  it 
  attacks. 
  

  

  As 
  Schweinitz 
  does 
  not 
  describe 
  the 
  fruit 
  of 
  this 
  fungus 
  I 
  subjoin 
  

   the 
  following 
  description 
  of 
  its 
  characters 
  : 
  

  

  Asci 
  cylindrical 
  ; 
  spores 
  uniseriate, 
  abruptly 
  narrowed 
  at 
  one 
  end 
  

   and 
  divided 
  by 
  an 
  obscure 
  septum 
  into 
  two 
  very 
  unequal 
  parts, 
  color- 
  

   less, 
  .0004'-. 
  0005' 
  long. 
  

  

  This 
  fungus 
  is 
  manifestly 
  closely 
  allied 
  to 
  Sphceria 
  morbosa, 
  which 
  ' 
  

   some 
  European 
  mycologists 
  have 
  referred 
  to 
  the 
  genus 
  Cucurbitaria^ 
  

   but 
  as 
  the 
  erumpent 
  character 
  of 
  the 
  Cucurbitarige 
  is 
  not 
  present 
  in 
  

   S. 
  Collinsii, 
  the 
  species 
  is 
  left 
  where 
  Schweinitz 
  placed 
  it.
