I have a couple of mature horse chestnuts that are being girdled by
longitudinal strips of dead wood. The death is initially concealed by the
bark but when it falls off it reveals areas of bare wood mainly surrounded
by healthy callus tissue. This is going on all over the trunk and main
branches. I haven't seen any fruit bodies.
I've checked out Strouts and Winter but they don't mention B. inquinans on
Aesculus although it is the closest description I can find. I don't think
it's drought (there has been no evidence of wilting all summer).
Any help or pointers gratefully received.
John
