    As far as I know, the European white elm (Ulmus laevis) is also quite 'resistant' to DED (it's as susceptible to the fungus as the other elms, but the bark beetles don't seem to like it).

    Just kidding, I hope

    In my opinion that's impossible. By the way: what's the point in keeping it if you want to stop all insect and fungal activity?

    I'd say perennial cancer too, maybe nectria galligena. The concentric rings and the swollen bark might be symptoms of this fungus.

    Hi Guys, Thanks for the replies. It's not a job I've done, I just happened to pass by, so I don't have much background info. I contacted the tree officer and he told me they did a tomography of the trees they suspected to be rotten. Don't know who did the VTA or what the symptoms were, but to give you an idea what the trees looked like, I included a picture of a neighbour tree they felled as well. The trees are besides the tramway (and were pruned back quite severely in the past) and cars used to park between the trees. So there's an overall decline in the condition of the trees. Apart from that, I didn't notice anything worth mentioning. I did not take pictures of the rot higher up in this stem, but i do have some of another tree on the other side of the tramway, with similar looking rot in a younger stage. Maybe that will help? The other trees that were felled had a different looking decay type. Thanks again, See ya, Tom

    Hi, I don't know if this is the right place to post this one, since there's no picture of a fungus, but I'll try anyway I found this rot on an Aesculus hippocastanum. There was no fruiting body and there were no big wounds at the stem base. The rot was very wet and clay-like, didn't look like anything I've seen before. Any ideas on the type of rot and the cause of it? Thanks in advance, Tom
