  iEciDIUM 
  PYROLATUM 
  ScJlW. 
  

  

  This 
  seems 
  to 
  be 
  one 
  of 
  the 
  connecting 
  links 
  between 
  iEcidium 
  

   and 
  Uredo. 
  Leaves 
  affected 
  by 
  it 
  are 
  more 
  erect 
  than 
  the 
  

   others 
  and 
  have 
  a 
  pale 
  sickly 
  appearance, 
  so 
  that 
  it 
  is 
  not 
  

   difficult, 
  in 
  looking 
  at 
  a 
  patch 
  of 
  the 
  round 
  leaved 
  Pyrola, 
  to 
  

   tell 
  at 
  a 
  glance 
  what 
  leaves 
  are 
  affected 
  by 
  the 
  fungus. 
  

  

  iEciDiux 
  Euphorbia 
  Pers. 
  

  

  This 
  species 
  occurs 
  quite 
  commonly 
  some 
  seasons 
  on 
  Euphor- 
  

   bia 
  maculata 
  in 
  company 
  with 
  Uromyces 
  Euphorbia*. 
  The 
  

   branches 
  whose 
  leaves 
  are 
  affected 
  by 
  it 
  are 
  more 
  erect 
  than 
  

   the 
  others 
  and 
  more 
  slender 
  in 
  their 
  mode 
  of 
  growth. 
  

  

  Nectria 
  pulicaris 
  Tul. 
  

  

  The 
  spores 
  in 
  this 
  species 
  are 
  described 
  in 
  the 
  Handbook 
  of 
  

   British 
  Fungi 
  as 
  "elliptical 
  or 
  pyriform." 
  In 
  the 
  fungus 
  

   inhabiting 
  old 
  corn-stalks 
  and 
  referred 
  by 
  some 
  botanists 
  to 
  

   this 
  species, 
  the 
  spores 
  are 
  oblong-fusiform. 
  

  

  Xylaria 
  digitata 
  Grev. 
  

  

  A 
  Xylaria 
  occurs 
  quite 
  frequently 
  in 
  our 
  woods 
  which 
  has 
  

   the 
  smooth 
  stem 
  of 
  this 
  species 
  and 
  the 
  short 
  spores 
  of 
  X. 
  

   Hypoxylon, 
  thus 
  ranking 
  intermediate 
  between 
  the 
  two. 
  I 
  am 
  

   not 
  fully 
  satisfied 
  whether 
  it 
  should 
  be 
  considered 
  a 
  distinct 
  

   species 
  or 
  a 
  variety 
  of 
  one 
  or 
  the 
  other. 
  The 
  true 
  X. 
  digitata 
  

   is 
  quite 
  rare 
  in 
  our 
  State. 
  

  

  RhYTISM 
  A 
  LINEARE 
  P7c. 
  

  

  This 
  should 
  be 
  referred 
  to 
  the 
  genus 
  Hypoderma. 
  It 
  is, 
  

   however, 
  quite 
  distinct 
  from 
  H. 
  nervisequum 
  to 
  which 
  one 
  

   writer 
  has 
  referred 
  it. 
  

  

  Hysterium 
  clavisporum 
  C. 
  & 
  P. 
  

  

  I 
  have 
  never 
  been 
  able 
  to 
  detect 
  the 
  narrow 
  linear 
  orifice 
  of 
  

   the 
  genus 
  Hysterium 
  in 
  this 
  species. 
  In 
  my 
  opinion 
  it 
  belongs 
  

   rather 
  to 
  the 
  genus 
  Dothidea. 
  The 
  same 
  may 
  also 
  be 
  said 
  of 
  

   Hystertum 
  Rimincola 
  Schw. 
  

  

  Dothidea 
  Dalibard^e 
  P7c. 
  

  

  This 
  rare 
  species 
  has 
  occurred 
  near 
  Mud 
  Pond 
  in 
  Hamilton 
  

   county. 
  

  

  Valsa 
  rufescens 
  Schw. 
  

  

  Mr. 
  J. 
  B. 
  Ellis 
  informs 
  me 
  that 
  the 
  specimens 
  of 
  this 
  plant 
  in 
  

   the 
  Schweinitzian 
  Herbarium 
  have 
  simple 
  cylindrical 
  spores, 
  

   .0003'-. 
  0004' 
  long. 
  This 
  would 
  make 
  it 
  distinct 
  from 
  V. 
  acu- 
  

   leans 
  Schw. 
  with 
  which 
  it 
  has 
  sometimes 
  been 
  confused.
