 Drurmn.  Swan Riv.  Crypt., by Dr,  Taylor.  It is  only a very fibrUlated form of U. Jlorida, Acb., not mucb  different  
 from  U.  strigosa.  Mr. Lawrence has collected barren,  sorediated  forms, witb a black base and  blackish extremities,  
 w'ithout  fibrilla, which  are uot veiy  unlike  U.  melaxantka,  at an altitude of  3,500 feet, on the  highest  parts  of  the  
 western range of mountains.

 Mr.  Gunn’s specimens are above two feet long,

 Bai-rcn and sorediated,  and very sparingly collected.

 1.  E v ern ia   fu rfura cea ?   (Mann;  Fries, Lich.  Eur.  p.  26). 
 H a b .  Cheshunt,  Archer,  fertile. 
 An aged, unsatisfactory specimen,  black beneath, but  above more resembling E. prunasiri, Ach.;  upper surface  
 much  coiTugated.  Possibly something different ft'om E. furfuracea or E. prunasiri.  I   have  not seen a  description  
 of Evemia inúndala, Nyl.,  from New  Hollaud. 
 Gen. I I I .   RAMALINA,  AcL 
 1.  Ramalina  ca lica r is  (Fries, Lich.  Eur.  p.  30).—Approaching \&t. geniculata,  Bab.  I.e. 
 H a b .  Esk, Launceston,  completely  investing  shrubs  of Hgmcnantkera angustifolia,  Gunn. 
 The specimens agree  substautiaUy  with E. fastigiata, Ach., but  still more  ivith  the  fom  called R. geniculata  
 by Dr.  Taylor. 
 0 .  ovalis, Bab.;  thallo  ovali  piano  tenuiore,  apotheciis minutis,  confertis.—R.  ovalis,  T a yl.! MSS. 
 H a b .  Tasmania, Gunn. 
 Apothecia  minute,  scattered  over  the  surface  of  the  somewhat  membrauaceous,  oval  froud,  which  is  1-2  
 inches long.  One of  the many modifications of  the form called R. fraxinea, Ach.—Laurer’s var, membranacea, Bab.  
 1. c.,  has the fronds narrower and longer,  and  the apothecia marginal;  but  it is perhaps hai'dly worth while to dwell  
 on minute  differences in this most  vaiiable genus. 
 2.  Ramalina  p u silla   (Fries, Lich. Eur.  p.  2 9 ;  Nyl. Enum.  p.  99). 
 H a b .  Macquarrie  Plains,  on  decayed wood,  Oldfield.  Recherche  B a y ,  dead  twigs, Lake  St.  Clair,  St.  
 Patrick’s River, Gunn.  Cheshunt,  on live  bark  and  dead twigs. Archer. 
 1 have already, in the  ‘ Flora of New Zealand,’ expressed an opinion that this is not distinct from the foregoing.

 H a b .  Cheshunt, Archer.  Collected  also  in Tasmauia b y   Lawrence,  Gunn,  Stuart,  and Ilooker. 
 Various  specimens differ amongst each other in the  consistency of the thallus; some of Mr. Archer’s  specimens  
 are  coriaceous,  others  quite membranaceous.

 H a b .  Cheshunt, Archer. 
 ■Well-marked fertile specimens.  Seemingly  rare  in  the  southern  hemisphere, but  occurring  in  the  Himalaya  
 Mountains,  as well as in Europe and North America.

 p.  271).—N.  pallens ?, Nyl. Enum.  Lich. p.  101. 
 Hab.  Ou  bark:  Cheshunt, Archer.  Mount Wellington, Hooker. 
 Nylander’s  enumeration omits all notice of N. australe.

 Hab.  Rotten  wood:  Johnny’s  Creek,  Oldfield.  Cheshunt,  on  dead  wood.  Archer.  Mount  Wellington, 
  Hooker and  Gunn. 
 The specimens  (of  a  deep-brown  colour)  agree  with  one  from Staten Land  marked Nephroma cellulosum in 
 Menzies’  handwriting.  N. plumbeum, Mont.!  Fl. Fern.  n.  7, seems to  be the same plant, but somewhat paler, whicli 
 has  been found also by Gunn.  Found  in Chili,  according  to  Nylander  (who keeps N. plumbeum and N.  cellulosum  
 distinct),  as  well  as  in  Juan  Fernandez.—P l a t e   CXCIX. »7.  Fig.  1,  apothecium;  2,  under  surface  of  ditto;

 Hab.  Among Mosses,  on wood,  etc.  Everywhere,  all collectors. 
 Fertile  specimens  are  bright,  and  often  much  pitted,  and,  being  destitute of  the  yellow  soredia  which  are  
 usually present on the barren fronds, wear a somewhat different appearance to the European  state of the plant. 
 3.  S tic ta   C o len so i  (Bab.  I.e.  t.  123). 
 Hab.  Very abundant  in forests,  on Fagus,  Gunn,  Hooker. 
 Less  divided than the New Zealand form.

 Some specimens are less distinctly flabelliform than the  ordiuai'y state of  the plants;  others,  collected  by Mr.  
 Oldfield,  resemble the  common type,  but are much smaller.
