    Yeah, not a great shot but it's a significant sized root that's partially submerged. Not one of our trees Guy, so can't comment on whether it is on any list for removal. I didn't see any SGR's having been removed recently or historically but I don't know the site too well, to be honest. It's the UK's National Arboretum, well worth a visit if and when you're back this way. Forestry Commission - Westonbirt, The National Arboretum - About Westonbirt (England) .

    Girdle on an Acer platanoides at the Westonbirt Arboretum. The Coprinus are possibly directly associated (saprophytically) with the dysfunctional root system in that area due to the constriction of the girdling root. .

    Inspired Mr Hunike .

    Good one .

    Arb Association magazine. If you go this weekend, you'll probably be able to pick one up. .

    Gotta love squamosus, such a photogenic species .
  7. David Humphries
    Probably .

    Rubbish memory Here on (dead) A. saccharinum and A. cappadocicum .
  9. David Humphries
    On Acer yes, on saccharinum, I can't remember. .
  10. David Humphries
    Nice shots Chris .
  11. David Humphries
    Yep, can find it on a wide variety of sub strata wood chip, wood ant nests, the ground, dead trunks/branches etc.... usually found when its bright yellow. .
  12. David Humphries
    Fuligo septica or perhaps one of your team had a big night out .

    Sorry Jake, I should have probably expanded on that a bit more. Melanine is a black coating that Armillaria mycelium lays down protecting the wood against elements and other organisms for its own benefit. I believe it's made of the same substance as the black coating seen on Rhizomorphs. See post 5 of this thread below..... http://arbtalk.co.uk/forum/fungi-pictures/29219-armilaria-central-cavity-decayer.html .
  14. David Humphries
    Yep, sounded dull during sounding. Just didn't know the size or extent of the decay/cavity. .

    We took the tree down last week and had a look at the cross section at the base earlier today. The above cross sections appear to show a brown rot toward the outside (not confirmed, but I suspect Rigidoporus ulmarius) and a white rot toward the centre. The cavity wall was coated by Melanine, which is likely to be Armillaria. Always interesting to see how the Resistograph compares to the cross section .

    Urban ash that's been in decline for the last couple of years. Slight lean toward the road and foot path. We inspect this tree once a year and hadn't noted any fungi fruiting other than Daldinia around some older prunning wounds. Put the Resistograph the base of the stem to see what was going on. Roadside showed sound wood until a central decay about 30cm in. Opposite side showed less sound wood (about 12cm) before it hits the decay/cavity The quadrant reading taken between the above two appeared a lot more significant .

    seems to be set to private?

    It's good to take the time to explain a new kingdom to people who don't know much about it. My favourite fung from today were these Pleurotus pulmonarius (pale oyster) from a standing dead sycamore .
  19. David Humphries
    Woah nelly, too excited by half Its just a load of fung ! .

    Saw some old neglected ones in beech trees in the mountains of the Basque a few years ago. Imagine it was shepherds and woodsmen mimicking what they saw happening naturally in pasture and woodland where bees would colonise natural cavities. If there were more trees left standing with natural cavities (target dependent) then we may have more woodland bees, like in this last image. .

    Possibly the Arb show, though depends on a few things at work this week. .

    I think it's the mindset of having been an apprentice 30 years ago Paul. I was given an opportunity at 16 and was shown the ropes. It's quite a privelage to offer that same opportunity to new people to the industry, and be part of their journey. .
  23. David Humphries
    Our apprentice had the opportunity to dismantle his first tree last week. He'd only used spikes once before on a practice pole rescue. Did very well and looked pretty comfortable in what was a fairly tight spot. .
  24. David Humphries
    Going to be a good fruiting year I think. .
  25. David Humphries
    Liking both the sweet chestnut and that beech .
