Extensive Ganoderma resinaceum decay on Turkey oak (Quercus cerris)

Whilst up at Hampstead Heath, the arborists showed me a large (but very heavily pruned, as it sits right by a road) Turkey oak (Quercus cerris) that was host to Ganoderma resinaceum. Certainly some very extensive decay, which has also extended into a buttress root on one side of the tree.

Not only can we see a large hollow at the butt-root plate interface, but also plenty of sporophores – all of which are rather large.

Looking round the other side of the tree, we can see that decay has spread into a buttress root.
