Any opinions will be appreciated.

monitor!

 

beech apparently do not result in an infectious reproduction cycle of P. ramorum, but in any case an acurate diagnosis would be needed before any such prognosis could be entered into.

I spotted this, (phytophthora), on a beech alongside a private road. I first saw it about 5 years ago and the tree seems fine.

However, we now do work at the site and on closer inspection it has ustulina to boot. We may end up taking it down though the client is keen to keep it.

ok thats great,cheers tony will monitor it closely over the next few years,if diagnosis is correct, what would be obvious signs within the tree ?

Paul,

Once the hyphae of Ustulina invade the cambium of a beech, it can also produce small cracks in the bark at the base of or higher up the trunk, from which a black ooze is secreted.
