 V E R Y  frequent  on  the  Shepherd's  Purfe,  T'hlajpi  
 Burfa-pajloris,  as  is  the  Uredo  Thlafpi,  tab.  340.  This  
 has  longer  ñems  than  that,  wliich  are  often  not  perceptible, 
   and  grows  on  the  outfide  of  the  plant,  without  
 the  cuticle  for  a  covering.  May  this  not  be  the  
 fame  one  lefs  deeply  feated  in  the  plant ?

 FARINARIA  SEMINARIA.  
 T H I S  little  produíUon,  found  on  leaves  of  a  Willow,  
 not  yet  defcribed  I  believe,  was  fent  me  by  the  Rev.  
 J. Holm  of  Cambridge.  It  appears  to  agree with  fome  
 other  things  in  my  colleftion  which  are  not  referable  
 to any  known  genus.  I therefore  call it Farinaria,  being  
 chiefly  compofed of  fine  powder.  
 No.  I.  
 Forms  a  little  white  neft  holding  black  compared  
 powder-like  feeds,  if I may  fo  call them  ;  fome I  found  
 empty,  with  the  impreffions  remaining  where  thefe  
 feeds  feemed to  have  been.  
 No.  a.  FARINARIA  AURANTIACA.  
 Are  fomewhat  ovate  particles  fcattered  on  the  leaf,  
 of  an  orange-colour,  more  or  lefs  in  bundles;  fome  
 in  a  compacted  mafs,  others  forming  a  kind  of  nail  
 mixed  with  a few  cottony  filaments  towards  the  edges.  
 No.  3.  FARINARIA  ROSEA.  
 Rofe coloured  particles  rather  indiflin¿l, and  neñling  
 with  fome  hairs  at  the  extremities more  or  lefs  enclofing  
 them.

 AGARICUS  vuLPiNus.  
 FOUND  at  Iflington  in  a hollow  elm.  It  was  quite  
 feffile, the  gills  reaching  to  the  tree  on  which  it  grew.  
 The  pileus  is  thickifli,  very  rough  on  the  furface,  and  
 fomewhat  of  a  fox-colour.

 AGARICUS  PLANUS.  
 T H I S  curious  Agaric  was fent  by  the  Rev.  Dr.  Abbot  
 of  Bedford.  There  is  nothing  particularly  ftrikmg  m  
 its  appearance  till  we  come  to  look  at  the  gills,  the  
 edges  of  which  are  obtufe  or  flattifh;  from  whence  
 hangs  a  loofe  powder,  appearing,  when  magnified,  to  
 confift of  minute,  round,  pellucid  globules.  The  refl:  
 of  the  gills  is  compofed  of  two  feries  of  ovate  and  
 fomewhat  fnufF-coloured  veficles.

 AGARICUS  SORDIDUS.  Bickf.  Crypt, fafc.  i.  t.  3 . /  i.  
 V ^ E  prefume  this  is  the Agaricus  fordidus  of  Dickfon,  
 and  the  name  accords well  with  it  when  gathered  in  a  
 wet  ftate.  In  dry  weather  its  furface  is  fatiny,  and  
 agrees  well  with  A.Jericeus  of  Bulliard  and  A.  rufus  of  
 Withering.  It  varies  both  as  to  the  pileus  and  Jlipes,  
 and is  either  of  a  yellowiih,  brown,  or  greyifh  colour,  
 and  often comes very  near  to  1.161.  of  this work.  The  
 gills  of  each  are  fometimes  fcarcely  fixed.

 AGARICUS  PLicATiLis.  Curt.  200.  
 T H I S  Agaric  may  be  heft  known  in  its  latter  ftate,  
 when  the  gills  are mofl  diftant  from  the  Jlipes,  leaving  
 a  ring  round  it:  at  the  fame  time  the  centre  of  the  
 pileus  becomes  deprefled.  The  reft  is  plaited,  and  the  
 ridges  rife  above  the  centre.  The  gills  are  few,  frequently  
 only  one  at  each  plait.
