Peniophora sp.?

On my trip to Horton Wood on Monday, searching for Spring Hazelcup Encoelia furfuracea, I came across this dried-out, cracked-up resupinate fungus.

I thought it was growing on Hazel, but my winter tree-identification still leaves a lot to be desired.

One of the things I've found difficult, in getting into fungus recording, is it's very hard to know what you don't know.

Starting out with the Collins Complete (photographic) Guide, I'd have been inclined to call this something like Peniophora cinerea (one of the five Peniophora species that gets a mention in the Collins book)...

However, having recently purchased The Resupinates of Hampshire (2017), I now realise there are 17 different Peniophora species featured in that guide; many of which look, well, rather similar.

So I think I'll leave this here, until  I've learnt a bit more about resupinates.
