An interesting relationship going on here, which has been confirmed as Ganoderma australe colonising a larch specimen through microscopic analysis by a professional mycologist. This particular larch is wonderfully clad with ivy, though is still alive (just!). I came across this approximately a week ago and was quick to get it assessed, given the rarity of the relationship.
Not much to add here, besides reiterating it being a very infrequent occurrence – if at all recorded before and subsequently confirmed, in the UK. Cool, eh!

If it’s so rare to find, is it not best just to leave it alone?

Most of the bracket remains. I only took a slice, in order to send it to Kew for formal assessment and recording in the FRDBI. Ganodermas are perennial – it’ll grow over the functional area. There was a wholly senescent bracket adjacent, so this is long-standing decay and thus millions (if not billions) of spore have been ajected from this fungu’s fruiting bodies, no doubt continuing its genetic lineage.

I suppose in our position interference is bringing something sustainable. I think it’s all the want on destruction that goes on needlessly in the world that triggers me to leave anything I can alone in nature.
