Dear Eric, thank you for your request and picture.
According to the photo, it is about Phellinus ferruginosus.
Fruiting bodies are annual and also perennial, 0.1-1.0 cm thick, decaying in an area of several square centimetres and even square decimetres, strongly attached to its base. Predisposed are tree species growing in sites with the humic soil. It occurs commonly in Europe, in the north of Scandinavia it is bordered more or less with the northern border of oak occurrence. The similar fruiting body is formed by Phellinus ferreus that differs only in microscopic features and moderately also in host trees. The mycelium causes white rot of attacked wood.
It lives parasitically or saprotrophically on the wood of hardwoods and conifers. Host selection is sometimes quite specific for a particular species and is an important defining feature.
With best regards,
Valeria
