Diplomitoporus flavescens has a
circumpolar distribution that extends to eastern Canada.[8] The fungus is rare in Northern Europe, where it is restricted to
old-growth forests that are dominated by
spruce trees. In this region it tends to prefer
host trees that have no or few other fungi growing on it, and that have fallen in a relatively healthy state.[9] The fungus has also been recorded in the
polypore-biodiverse
Changbaishan region in northeastern China.[10] In 2016, D. flavescens was reported for the first time in Turkey, where it was found growing on a branch of
black pine.[11]
