 AGARICUS  v iOL.\cEus.  Linn.  Sp. Pl.  1641.  With.  v.4.  
 p.  207.  
 T H I S  varies  to a purple  all over.  The ñipes  is  very  
 cottony, extending  to  the edge of  the  pileus,  and forms  
 an annulus  which  often catches  the  ferruginous  feeds.  
 The  tafte  is  fimilar  to  A.  campejiris,  the  common  
 mufliroom,  but  not  fo  good.  This  fpecies  is  fometimes  
 fold  at  Covent-garden  market,  under  the  name  
 of Blewits  for making  ketchup.

 AGARICUS  TURFOSUS.  
 I  W A S favoured with  thefe gathered  by  the Rev.  Mr.  
 Francis  of  Holt,  Norfolk,  November  1798,  who  finds  
 them  on heathy  ground  where  turf  ftacks have  flood.  
 They  fomewhat  referable  MeruUus fcetidus  of  the  
 Rev.  R. Relhan.  See Eng.  Fung.  tab. 21.  They  however  
 have  little  fcent,  and  the  ftipes  is  fmooth,  the  
 whole  plant  alfo  lefs  rigid.  Perhaps  it  fliould  be  a  
 Merulius ?  I hope  to fettle  that  point  at the  end  of  the  
 work.

 BOLETUS  SPUMEUS.  
 T h i s ,  which  I  believe  to  be  a  new  fpecies,  oozes  
 from  decaying  elms  in  a very foft frothy mafs,  hardening  
 in  a day or  two;  and, if  it  dries  favourably, the  pileus  
 becomes  hifpid.  The  pores  are  fmall,  and  nearly  
 round;  the  tubes  not  long.  I  have  found  it  in  Keniington 
 gardens,  at  Kennington  in  Surry,  and  other  
 places.

 BOLETUS  BETULINUS.  Bull.  312.  
 OUND  for  feveral  years  on  an  old  birch  near  Hevingham, 
   Norfolk,  by  the  Rev.  Mr.  Alderfon.  The  
 iliort  lateral  ñipes  feems  to  imbibe  much  of  the  reddifli  
 hue  of  the  inner  brown  bark  of  the  tree,  and  
 even granular  particles of  its fubftance.  The outer coats  
 are of  a lightifli brown  ;  cracking from the pure  white,  
 clofe,  cork-like  fubftance of  the  plant  in  advanced  age,  
 as if  from  a white-waflied  wall.  The  pores  vary,  and  
 are  fliortifli  and uneven at  their mouths, of  ayellowifli  
 hue,  and  pretty  clofely attached  to  the fubftance of  the  
 plant.

 AURICULARIA  CARTOPHYLLEA.  Bull  378.  
 HELVELLA  CARYOPHYLLEA.  Bickf.  Crypt.fafc.  i.  20.  
 A  VERY  common  paraiite  on  the  expofed  fantaftic  
 roots  of  old  firs  in  autumn.  The  fpecimcns  are  of  a  
 woody  or  rather  leathery  fubftance, and  grow  in  various  
 forms,  attaching  themfelves  by  their  backs  to  
 any  thing  in  the  way;  their  colour  is moftly  a  ferru- 
 .ginous  brown,  fometimes  with  white  edges.
