During recent years, several new species of Peltigera have attracted attention
in Sweden. As a consequence, several of the specific characters commonly
used in examination keys and short descriptions are now obsolete. The present
paper describes the large tomentose Peltigera-species P. canina, P.
kristinssonii, P. membranacee, P. ponojenrrJ, P. praetextata, P. retifuveata and
P. rufescens. The authors ambition was to describe characters useful for the
identification of the species, rather than attempting to cover the morphology
completely. Short notes on the ecology and distribution within Sweden are
included.

Det har varit relativt Htt att med korta uttryck
karaktiirisera arterna i Peltigera caninagruppen:
P. praetactata har isidielika bildningar,
P. rufescens har smala, krusiga lober
med uppvikt kant, i princip iir allt Ovrigt P.
canina speciellt om det finns tufsiga rhiziner.
Det har f6ljaktligen varit Htt att gora en enkel
bestdmningstabell. Men sedan Vitikainen
