Not sure what this is. I thought it might be a Poria of some sort. It is growing on Oak I believe. Its a parchment type fungi spreading on denuded tree trunks. It appears to be a perennial maybe if you look below the image you can see older part of this fungi below the red area. Tt is covered with a white mold.

I agree with Irene

I agree this has pores visible in the first photo. Edee originally thought Poria which also indicates he saw pores (presumably). Pores rules out Peniophora and Amethicium chrysocreas. Ceriporia spissa is bright orange but darkens to reddish brown (Gilbertson and Ryvarden 1986).

Chemical test?

Try a drop of KOH on your specimen.

I have posted photos taken in July in the Northern West Virginia panhandle.

does not have pores. This one has..

if you look at the highest resolution in the first picture..

I have read descriptions and looked at several pictures of it in different stages.
Young pores should be vivid orange, like in this picture:
Older specimen turn tan to brownish red, like this:

C. spissa is certainly a “could be”, but of course closer examination is needed to make it a definite ID. Meruliopsis or some other Ceriporia is possible too.

I don’t think it’s Cerioporia spissa

The color seems wrong and I don’t even see pores on it. Check the images here for the way it looks in California (which could be different I guess): Did you look at it microscopically? Could it be a Peniophora?

Thanks for the lead

I notice this in July on the same log but at the time there was just the dead part on the bottom and the upper part was not colored red like this but more of a tan, I didn’t think that much of it. Since the snow and cold weather this has come to life having now turned this red color and now has a soft rubbery texture. it looks really close to Ceriporia spissa so we are going to go with that for now
The first idea

that came to my mind, was Meruliopsis taxicola, but you apparently have some lookalikes that have to be checked (more in NA than in Scandinavia).
One of them is Ceriporia spissa.

More than one layer of a polypore doesn’t always mean that it’s perennial, especially not if they are easy to separate. New annual fruitbodies can grow upon old ones now and then.
