 FIG.  5.  S.  HEDEEJi.  
 THIS  generally  rifes through  the  cuticle  of  the  leaf  
 in  a  fomewhat  conical  form.  
 F I G .  6.  S.  BETULINA.  
 THIS  feems  to  fwell  the  cuticle,  forming  an  oblong  
 black  fpeck  on  the  furface,  and  a woolly  ferruginous  
 margin.  
 T A B .  CCCLXXN.  
 FIG.  I.  SPH^RIA  SALICINA.  
 T H I S  differs but  little from  the  I". Lauri,  t.  y]X-fig-  4.  
 and  ought  to follow it.  The  mouth  on  the  upper  fide  
 of  the  leaf  has a  fmaller  covering,  and  the  bottom  of  
 the  fphierule  by  its  peculiar  conftruaion,  after  penetrating  
 the  leaf,  forms  a black  circle,  foraetimes  with  
 a  black  dot  in  the  middle.  
 F I G .  2.  S.  PERFORATA,  
 T H I S  forms  roundiih  holes  through  the  cuticle  of  
 the  fticks on which  it  is  found,  iffuing  from  the  cortex  
 either  fingle  or  in  bundles,  with  their  mouths  a  little  
 beneath  the  holes.  
 FIG.  3.  S.  EL1.1PSOSPERMA  ?  Bull.  492. Jig.  3.  
 THE  feeds  were  fo  conglutinated  together  in  our  
 fpecimens,  that  we  could  not  pofitively  difcern  their  
 elliptic  forms,  though  we  were  almoft  confident  they  
 were  of  that  figure.  
 FIG.  4.  S.  BOMBARDICA.  Bolt.  
 A  VERY  common  Spharia,  often fpreading over  old  
 flumps  of  trees;  and  often  one  over  another,  not  unaptly  
 refembhng grains of  gun-powder.  In  the  young  
 ftate,  a white  powder  iffues from  the  mouths,  afterwards  
 a black  jelly  or  powder,  till  at  length  they  become  
 empty  fphajrules.  
 FIG.  5.  S.  CoRTicis.  
 THIS  Fungus  reaches  entirely  through  the  cortex.  
 The mouth perforating the  cuticle  fwells it a very  little,  
 and  fometimes  a  ftain  appears  round  it.  
 F I G .  6.  S.  ASPER.  
 WE  put  this  among  the  Sphasria from  its  refemblance, 
   although  it  feems deftitute  of  the  common  covering  
 of  the  genus.  It burfts  the  cuticle  in  fo  rough  
 a manner  as  to  give  the  ftick  it  grows  on  the  appearance  
 of  a  rafp  or  file.  
 FIG.  7.  S .  MARGINATA.  
 THE  mouth  of  this  Spbteria perforates  the  cuticle,  
 and  the  edges  turn  back  upon  it,  forming  a  broad  
 whitifh  border:  fometimes  thefe  have  2 or  3  perforations  
 in  them,  and  2 or  3 mouths  beneath.  
 F I G .  8.  S.  SUBIMMERSA.  
 ABOUT  half  of  each  fphaerule  rifes,  fwelling  the  
 cuticle  hemifpherically,  and  giving  it  a dark  greyiih  
 tinge.  
 F I G .  9.  S.  PUNCTUM.  
 THE  fphserule  is  nearly  round,  buried in  the  upper  
 part  of  the  cortex.  The  mouth  perforates  the  cuticle,  
 and  has  round  it  a  blackifli  ftain.  
 FIG.  10.  S.  EMERSA.  
 THIS  burfts  through  the  cortex,  forming  a  mouth  
 under  the  cuticle,  with  a fpreading  black  circle  round  
 it,  occafionally  perforating  the  cuticle  with  a  fmaller  
 circle  or  ftain  round  it.  
 F I G .  II.  S.  CRUSTACEA.  
 THE  cruftaceous  cover  of  this  Fungus  fpreads  on  
 the  outfide  of  the  wood,  in  parts  forming  little  puftulate  
 fphasrute,  wdth  fomewhat  pointed  mouths.  
 F I G .  12.  S.  INSIDENS.  
 ALWAYS  on  the  outfide  of  the wood,  or  nearly  fo;  
 fometimes  confluent, roughifla  and  hard.
