  Sph^eria 
  Collinsii 
  Schw. 
  

  

  This 
  occurs 
  in 
  the 
  Adirondack 
  region 
  on 
  leaves 
  of 
  Spircea 
  

   salicifolia. 
  The 
  branches 
  in 
  this 
  as 
  in 
  AmelancMer 
  Canaden- 
  

   sis 
  are 
  swollen 
  and 
  distorted 
  by 
  the 
  fungus.

  I 
  am 
  satisfied 
  that 
  this 
  is 
  only 
  a 
  form 
  of 
  BpJi&ria 
  ditricha 
  

   Fr., 
  a 
  species 
  which 
  has 
  been 
  referred 
  to 
  Sphserella, 
  though 
  in 
  

   my 
  opinion 
  it 
  is 
  a 
  good 
  Yenturia.
