hello,

color is sometimes changing, here is one in yellow:

I have done Google-search with "Lungenflechte Norwegen" - but I admit
not to be a lichen specialist, I have only looked in my private german
lichen guide

I think using Wikipedia "lichen" you will find more genera and species

now at least I am aware how wonderful those algae-mushroom creatures can
be, especially from an esthetical viewpoint
