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)

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 😄

Nice example Nick

Anomorphic form of Fistulina hepatica rather than the more common telomorphic form.

Yes, Meripilus. Tree is likely to be right royally fuched ! Examination would be needed to confirm how far the roots are compromised. The vascular columns ‘look’ sound but it’s how they connect to the roots will be key. How was the crown looking? Any fruit bodies away from the tree out on the roots?

I can’t answer that for you, without assessing the tree in the flesh, too many variables.

A slice of the fruit body showing the flesh and tube layer would make identification a bit clearer.

Ganoderma species I would of thought. Perhaps G. resinaceum

Pretty standard I would say
