The  Thelephoraceae  of  North  America  XL — E-  A.  Burt  discusses 
the  generic  characters  of  Tulasnella,  Veluticeps,  Mycobonia,  Epithele 
and  Lachnocladium,  as  well  as  the  characteristics  of  three  species 
of  Tulasnella,  two  species  of  Veluticeps,  two  species  of  Mycobonia, 
two  species  of  Epithele,  and  12  species  of  Lachnocladium.  Fifteen 
figures  and  one  clear  plate  of  nine  figures  accompany  the  article. 
A  Subterranean  Alga  Flora.  By  G.  T.  Moore  and  J.  L.  Karrer. — 
The  authors,  in  this  valuable  investigation,  inoculated  ten 
different  series  of  culture  bottles  with  soil  samples  from  various 
parts  of  the  Missouri  Botanical  Garden,  Woods  Hole  and  Santa 
Ana,  California.  The  cultures  were  taken  at  varying  depths  up  to 
one  meter  and  the  varieties  of  soil  examined  were  heavy  clay,  loose 
clay,  sand,  sandy  alkali,  sandy  gravel  and  humus.  The  subter- 
ranean cultures  were  obtained  from  places  where  the  soil  had  not 
been  disturbed  for  at  least  a  number  of  years,  in  order  that  the 
algal  growths  obtained  would  represent  those  typical  of  subterranean 
conditions  and  not  merely  surface  infections. 
They  tabulate  their  results  in  nine  tables,  Series  A  being  omitted 
in  their  tabulations.  The  authors,  however,  mention  that  Proto- 
derma  viride  and  Anabaena  appeared  in  the  latter.  From  the  records 
in  these  tables  the  authors  conclude: 
1.  That  there  exists  a  subterranean  algal  flora,  independent  of 
the  nature  of  the  soil  and  the  locality. 
2.  That  Protoderma  viride  occurs  constantly  at  the  greatest  depth. 
3.  That,  as  pointed  out  by  Esmarch,  the  flora  undoubtedly 
originated  from  the  surface  flora. 
4.  That  the  greatest  growth  in  the  cultures  was  at  a  depth  of 
5-60  cm.  A  list  of  seventeen  different  algae  found  in  the  cultures 
is  given,  together  with  a  statement  of  the  greatest  depth  at  which 
each  occurred. 
Culture  Experiments  with  Melampsora  in  Japan.  Three-  figs. 
By  Takashi  Matsumoto. — This  article  comprises  supplementary 
notes  on  cultural  experiments  with  Melampsora  on  species  of  Salix 
and  Populus.  It  is  a  sequel  to  the  writer's  first  article  which  was 
reported  in  Japan  in  1915.  Heber  W.  YoungkEN.
