    Not sure I agree with the fisti fruiting, we've got plenty of fresh fruitbodies just developing externally on oak and sweet chestnut currently. Very long fruiting season for hepatica this year. .

    You've got it bad Chris, not far from time for therapy mate Few bits and bobs from today at work .
  3. David Humphries
    Pholiota squarrosa I would think, did you get a look at any of the stems? They would have been fairly scaly if they were P. s .

    Mean the other way round, girdling leading to constriction of the vascular system of the buttress and associated root(s) leading to dysfunction and underside decay, just a hunch. http://arbtalk.co.uk/forum/tree-health-care/49361-girdled-roots.html .

    Grifola frondosa fruiting for the first time in a couple of years on this cherry. Unusual association, perhaps attributable partly from the root girdling .
  6. David Humphries
    Don't imagine things would move that quickly Jake, perhaps the rhizomorphs were in the root zone prior to the mukch being laid and the fruit bodies have just come through the mulch from below. .

    Coming out or staying Jake? .

    I wouldn't rule it out as tabescens, but one or two of them appear to look like they have a ring (or remnants) on the stem? Armillaria tabescens - The Ringless Honey Fungus - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists .
  9. David Humphries
    Armillaria mellea, honey fungus. Lots around at the moment .

    Veteran sessile oak that has sat within a large construction site at work (Hampstead Heath) for the last couple of years. It was subjected to a tear out of a large swept low limb during high winds about 5 years ago. So it lost a fairly significant portion of its canopy which unbalanced the crown. The trunk and major scaffold branches are heavily colonised by the brown rot decayer, Fistulina hepatica Due to its exposed position to wind load we've had it down on our veteran tree works list for quite a while, but access to it has only recently just reopened now that the construction compound has finished. Today Jack began its first phase retrenchment prune to manage the canopy balance which will be continued over the next five to ten years depending on ongoing vitality. .

    More likely to be one of the Ganoderma species that's become desiccated Danny. Fomes does associate with oak, but it generally would have a much deeper profile. Things to look for when identifying fungal species are things like spore colour and size of pores underneath the caps. Fomes has a pale/white spore and the Ganodermas have a brown/cocoa coloured spore. .

    No not porcelain Will, the would be much larger and have a a ring on the stem. I would think these are probably from the Mycena or Marassmius/Marasmiellus genus .

    Any idea on colour of the gills? .
  14. David Humphries
    Seems to me that they just keep on rolling on down that super-seasonal-highway one year to the next. This lot have had them infesting for 10 years and counting, not lost one yet .

    No substitute for getting up close and personal to assess health and vigour What system you climbing on these days Guy? Did you measure the regrowth? .
  16. David Humphries
    Six months on, looking good this morning (last two images) .
  17. David Humphries
    Liking that .

    Number 13 on this 300 year old sessile oak. Major scaffold snapped out during a strong gale about 10 years ago. Not sure how long this fruit body has been up here, as we only noticed it for the first time whilst working on the upper part of this canopy last week. .

    Looks like a hard perennial Ganoderma species to me. Probably australe but I wouldn't rule out pfeifferi without having someone do a scratch test on it. What was the Sparasis fruiting on Mr OakStag? .
  21. David Humphries
    Good one, always a nice find. It's interesting seeing the widening host range now that Elm is dissapearing. Have you seen it on anything else Chris? .
  22. David Humphries
    Yes, looked at those. I'll look a bit more in to it, but not sure that its somewhere to check a PP number as a customer, but thanks for that. .
  23. David Humphries
    Thats why a group of us went to Italy this summer to see it first hand in the flesh. http://arbtalk.co.uk/forum/tree-health-care/100779-ceratocystis-platani-canker-stain-plane.html .

    My understanding is that the Protected Zone status has been renewed. Turkey has literally just been added to the list of Euro countries with Ceratocystis platani. .
  25. David Humphries
    Thanks I've been looking at the Defra and plant health websites but it all seems geared up about 'issuing' plant passports, there doesn't seem to be anywhere to check PP numbers. The nursery where these were sourced from is now shut for the weekend, so I can't check with them. I've got the tees in quarantine until next weeks planting, just trying to make sure these haven't come from parts of the EU that have Plane Wilt (Ceratocystis platani) The Tag looks like they have come from Holland but I'm not sure where they came from before that. .
