Yes, it is fungus on a tree trunk. I'll try to find out what kind of fungus it is. Could it be a Turkish Tail / Trametes versicolor? The Norwegian name is Silkekjuke!
The fungus is word wide known. In Norway we can find it on hardwood along the coast of Oslofjord up to the Sognefjord.
Thanks Carol for asking!
