a little variable in surface colour but not unusual to be dark brown (slightly reddish) towards maturation. If in doubt always worth cracking open to look at flesh and tubes 👍

Fomitopsis betulina

Not one I see very often, but oddly enough I did come across one on a car park railing a couple of days ago. Literally parked right on top of it 😀

If it has gills rather than pores, try looking at Gloeophyllum sepiarium. (Conifer mazegill)

Moth larvae perhaps

Resinaceum be my guess

Have you got any images of the flesh and tube layer(s) Not sure what it is to be honest, but don’t think it’s either the anamorph or the teleomorph of Fistulina. last couple of images remind me of Heterobasidion, but the other shots don’t quite add up.

Nice ! Look like Inonotus hispidus don’t they.

Currently in Wroclaw, Poland at a trees and climate conference and have had the chance to look at the local trees and their fungal associations. Mostly from Szczytnicki park.

Look like Armillaria mellea to me, has the ring on the stem to rule out Armillaria tabescens (the ringless honey fungus) ideally would need to see the base to be able to rule in or out Armillaria gallica/bulbosa (the bulbose honey fungus)

Arb Association fungi on trees: An Arborists Field Guide

Yep

Very little text out there on it’s ecology, from observations I’d say it’s primarily associated with older root systems with associated dysfunction. I’ve excavated a couple of fruitbodies in the past to trace back mycelium to wood volumes and in both cases found it directly attached on dead roots. We have it hosting with pendunculate, sessile and red oak as well as beech, lime and hornbeam on our trees in north London. Don’t think it’s as scarce as records seem to indicate.

Mostly argentine tango but occasionally known to fox trot 😄
