PRAEMONITUM. 

Anni  quinque,  post  regressum  meuni  e  peregrinatione  per 
ultimos  Americae  australis  fines,  elapsi  sunt  et  nunc  tandem 
fungos  observatos  y.  collectos  publico  jure  facio;  tempe- 
statibus  pluribus  obstantibus,  opus  antea  absolvere  non  potui. 

Fuegia  montuosa,  sylvis  densissimis  pratisque  uliginosis 
circumtecta,  aere  humidissimo  hiemeque  modice  algido  do- 
nata,  flora  mycologica  ditissima,  typo  fere  gerontogeo, 
gaudet.  . 

Agaricinei  abundat,  Cortinarii  praecipue,  Hygrophori, 
Russulae  ac  Lactarii  tamen  deficiunt;  polyporei,  Boletis  ex- 
ceptis,  copiosissimi  etiain,  sed  paucas  exhibent  species;  fa- 
miliae  caeterae  plus  minusve  vulgatae;  inter  omnes,  quara 
maxime  insignes  Cyttariae,  quae  una  cum  polyporeis  alimen- 
tum  praecipuum  incolis  praebent. 

Species  repertas  in  1 200  circiter  puto  sed  quum  in  Slog- 
get  bay  (Amacowaia  incolarum)  naufragium  passus  sim, 
hymenomycetes  arrepti,  hyphomycetes  distenti  a  fluctibus 
fuerunt  et  nunc  500  species  tantum  mihi  pubblicare  possi- 
bile  est.

Basidiomycetum  diagnoses,  e  descriptioiiibus  iu  vivo  pe- 
ractis  excerptae,  saepe  taudeni,  characteriijus  sporologicis 
dcficientibus,  determinatioue  dubiosae;  ascomycetum  spe- 
cimiua  perplurima,  uotabile  etiam,  saepissime  sterilia  iu-
