    Wouldn't rule out Phytophthora sp (perhaps get a testing kit) But I wonder whether these may be some sort of target canker? They appear mostly to be circular and around old branch/twig collars. .

    I'm not so sure it's as simple as that Jake. The fruitbody is just a part of the fungus and I suspect that it's mycelium runs down at least the length of this long branch and possibly back into the trunk. The fungus will usually take the easy route to sporolation, which in this case probably has led it to fruit where there is a lot of dysfunction and decay so it can produce the sporocarp with the least amount of effort. I'd imagine there's probably a bit more to it than how I've just described it. I also imagine that a vast number of fungal species act both parasitically and saprophytically at different times on the same host. I think this is also true of mycorrhyzal fungi. .

    Interesting discovery. Red oak with long term Laetiporus sulphureus colonisation. Whilst assessing a recently detached limb from this tree (socket failure due to brown rot) we heard this little chap tapping away above. Normally I associate woodpecker activity on white rot decayed branches not brown rot like the below example. .

    Oh I'm all over it, just letting your nose lead you down the Id alley I had no internet last night, but have been comparing your flesh and pore layer shots against a couple of suspects this evening. I have a hunch. .

    About 4 or 5 fruit bodies at various stages of development on that oak Chris. We found another new host tree today. (Well Ali did to be accurate, geezers got his fungdar switched well and truly on) This one is No11 on the distribution map. Oak again. .

    Perhaps best eh ! Lol .

    Ha, ya fung photo groupie you ! .

    That occurrence was also on another big elder, don't think I've noted them on small elders before. .

    what a silly question !

    Rigidoporus ulmarius on an uncommon host. Big elder ! .

    Nuthatch giving me the 'evils' earlier today and a woody doing its 'picus' thing ! .

    Make it so .

    Fomes fomentarius colonising an Oak the other side of the fence at work. .

    That's appreciated Good luck with it. .

    Do both members of the 'delighted owners of FDW' club, share the cost of the chocolate digestives when they meet on the second Wednesday of each month? .

    I don't know the answer to that. Looking at the linked blog above, grafting of disease-resistant varieties has been tried, but I'm not sure how successful or sustainable that's been. I'm going to Italy in A couple of months for a workshop on the management of Ceratocystis, hopefully we'll get the opportunity to learn more about Xylella also. .

    No potential about it......... Phellinus punctatus (now - Fomitiporia punctata) - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists Found that to be a particularly interesting article in the journal .

    I might of, but then again, I might not have .

    Pondside rather than roadside this Horse chestnut with Rigidoporus ulmarius. Might splash the cars on the A road if it went over. .

    Personally haven't seen one fail at the graft, and we have a number of grafted coppers on the site. Some further discussion and images on this old thread....... http://arbtalk.co.uk/forum/tree-health-care/5372-bad-grafts-beech.html Based on the planned works, it sounds like consideration of crown reduction on your tree is prudent. .

    pretty common tbh, posted a couple of desicated ones on a pine log on the t'is the season thread a day or two ago. Often see them on burnt standing stems. .

    I'd imagine this is a developing Enteridium Enteridium (Reticularia) lycoperdon - slime mould - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists .

    We found that there was very little holding it up http://arbtalk.co.uk/forum/tree-health-care/31329-sometimes-you-just-have-look-little-closer-11.html .

    Timelapse of the air spading a fallen veteran oak root plate. We wanted to see what was holding it up and to have a closer look at the decay and dysfunction Before After . Interesting watching the level of public footfall going past this tree Instead of erecting safety boards we just stopped when people came by. During....
