  The 
  perithecia 
  are 
  epiphyllous, 
  the 
  spores 
  are 
  obovate 
  or 
  sub- 
  

   angular 
  and 
  are 
  involved 
  in 
  mucus. 
  The

  The

   The 
  species 
  is 
  remarkable 
  for 
  its 
  long, 
  pale, 
  wooly 
  hairs 
  

   and 
  its 
  light-colored 
  perithecia. 
  These 
  are 
  sometimes 
  so 
  

   crowded 
  together 
  that 
  they 
  appear 
  to 
  form 
  a 
  continuous 
  fleecy 
  

   stratum. 
  A 
  relationship 
  with 
  the 
  genus 
  Trichoderma 
  is 
  

   indicated.

  The
