  This 
  plant, 
  which 
  was 
  formerly 
  reported 
  under 
  the 
  name 
  Sphcero- 
  

   nema 
  Spina, 
  has 
  recently 
  been 
  characterized 
  by 
  Dr. 
  Berkeley 
  as 
  

   having 
  very 
  small 
  globose 
  spores. 
  The 
  plant 
  which 
  we 
  had 
  regarded 
  

   as 
  belonging 
  to 
  this 
  species 
  (Schweinitz 
  gives 
  no 
  description 
  of 
  the 
  

   spores), 
  has 
  spores 
  quite 
  different 
  and 
  must 
  be 
  described 
  as 
  distinct. 
  

  

  Sppi^eronema 
  Fraxini 
  n. 
  sp. 
  

  

  Perithecia 
  nestling 
  in 
  the 
  inner 
  bark, 
  covered 
  by 
  the 
  epidermis 
  

   which 
  is 
  pierced 
  or 
  ruptured 
  by 
  the 
  long 
  black 
  rigid 
  spiniform 
  ostiola 
  ; 
  

   globule 
  whitish 
  ; 
  spores 
  long, 
  slender, 
  curved 
  or 
  flexuous, 
  gradually 
  

   tapering 
  to 
  a 
  point 
  at 
  each 
  end, 
  generally 
  multinucleate, 
  colorless, 
  

   .002'-.0025' 
  long. 
  

  

  Dead 
  branches 
  of 
  ash, 
  Fraxinus 
  Americana. 
  

  

  The 
  long 
  rigid 
  ostiola 
  render 
  the 
  branch 
  prickly 
  to 
  the 
  touch. 
  

   The 
  fungus 
  is 
  sometimes 
  found 
  intermingled 
  with 
  Tympanis 
  Fraxini 
  

   of 
  which 
  it 
  may 
  be 
  a 
  condition.

  But 
  few 
  species 
  of 
  the 
  first 
  great 
  family 
  of 
  fungi, 
  the 
  Hymenomy- 
  

   cetes, 
  are 
  inabitants 
  of 
  living 
  plants. 
  A 
  single 
  species 
  and 
  the 
  mem- 
  

   bers 
  of 
  a 
  single 
  anomalous 
  genus 
  comprise 
  all 
  with 
  such 
  a 
  habitat 
  that 
  

   have 
  hitherto 
  been 
  found 
  within 
  our 
  limits. 
  The 
  species 
  of 
  Fxobasi 
  

   ditim 
  attack 
  and 
  transform 
  the 
  buds 
  and 
  leaves 
  of 
  Ericaceous 
  plants 
  

   into 
  soft 
  gall-like 
  swellings 
  or 
  excrescences. 
  It 
  is 
  not 
  known 
  that 
  they 
  

   actually 
  kill 
  the 
  plants 
  they 
  attack.

  Of 
  the 
  second 
  family, 
  the 
  Gasteromycetes, 
  probably 
  no 
  member 
  is 
  

   strictly 
  an 
  inhabitant 
  of 
  living 
  plants 
  though 
  several 
  species 
  occur 
  on 
  

   both 
  living 
  and 
  dead 
  plants. 
  Stemonitis 
  herbatioa 
  has 
  as 
  yet 
  been 
  

   detected 
  only 
  on 
  living 
  leaves 
  and 
  grass, 
  but 
  I 
  do 
  not 
  think 
  its 
  

   habitat 
  is 
  thus 
  limited. 
  

  

  The 
  third 
  family, 
  the 
  Coniomycetes, 
  doubtless 
  furnishes 
  more 
  fungi
