Ian,
I've seen Perenniporia like that. My next step would be to prod the bracket
with a strong knife. Perenniporia is very tough and leathery right through
to the centre, with a fairly featureless, light chocolate coloured flesh
(once you get into it). Ganoderma resinaceum is less solid with a more
brittle outer surface (as I recall). Juvenile characteristics can be a bit
tricky, and fungi seem to enjoy confounding our strong urge to categorise
everything but I think the fungus could well be Perenniporia and I'd use it
as a working hypothesis and see if it fits in with these further
characteristics.
Regards
Steve

Dear all,
I'm trying to identify a (juvenile?) white chalky fungal bracket found
between the buttresses of a veteran beech tree. After looking through
Lonsdale's Principles of Tree Hazard Assessment my hypothesis gravitated
towards Perenniporia fraxinea or perhaps Ganadema (resinaceum).
Ridgeoporous has also been mentioned too. Any ideas?
See attached.
Thanks,
Ian
