F.spraguei usually has darker, sometimes greenish rim and lighter-colored body. This mushroom has a rim that’s lighter than the rest of the body.

I thought about connection between I.resinosum and this mushroom

OK, I have a photo showing the same grouping with I.resinosum in the lower left. It seemed to be attached to a different log that was to the left of the one in question and touching it. I doubt there is a connection between the two. The mushroom in question has bodies too small to be a I.resinosum. I ’m adding the photo to this lineup (at the very bottom).

I. resinosum is irrelevant here

It’s correct that at the very bottom left was Ischnoderma resinosum – I’ve tried to choose pics without it seen but you spied it there. The main actor here is the mushroom bodies that take the majority of the screen – those are the mystery I’m trying to solve.

The mushroom on the bottom left appears to be Ischnoderma resinosum

seem that the color are not fine with that polypore it look like it is parasited to me so laetiporus is alway a possibility in that case
