Hi, did some tree felling recently in order to thin out a plantation of
200 trees, the free was a turkey oak abour 15ft tall and disfigured.
when felled to make way for other better specimens the remaining logs
and stump had black veined stains. I have never seen this before. Does
anybody know what it is?

Fungus mycelium, or the effects of it. Only a specialist could make a
decent guess at which fungus, as there are a lot of possible candidates.
