Last year i noticed one of the Oaks on a site known as Stour Meadows had a funny root flaring at the base and die back in the canopy. It is pictures 5,6 and 7 of the selection. Any ideas what may be causing it?

Thank you gerrit. No bark shedding yet and no signs of FB's. We are keeping an eye on it as it within falling distance of two footpaths (one tarmaced the other a desire line). Other than deadwooding we shall leave it to get on with what ever it wants to do. When it does die we shall leave it as a deadwood monolith with bat slots cut into the trunk and coronet cuts where possible.

this looks to me to be an old wound from an included union and the canker has complicated the woundwood rib formation, this can be fistulina

Could be, I saw this oak today for the first time, so I can't look back on its history.

It's standing close to a ditch along a dirt road in a small woodland with very old hazel (with Lactarius hortensis !), some old oaks and an about 80 years old solitary birch surrounded by lots of Amanita fulva, some Amanita muscaria, Leccinum scabrum, Russula aeruginea, R. betularum and R. claroflava.

well then given the locale population and the obvious inoculum potential, i would be very secure In pursuing Fistulina hepatica as a cause of the Fungal canker.

This morning, I monitored all the macrofungi associating with or on oaks (and birches) in this woodland and some surrounding forests, but there was no sign of bark necrosis typical of Fistulina, nor were any FB's around.

you know as well as I do that this detective work takes a relationship with the forest to bring out the shy life of the forest.
