    always very hard to be sure from so desiccated a sample, but I wouldn't rule out Meripilus giganteus which I've noted a few times on London plane. .

    I've no idea Ben in the mean time....... .
  3. David Humphries
    Oh there were one or two 'special' shots taken I'm sure they will be shown in the fullness of time .

    Was indeed a very large sporophore There are over 25 growth increments on this particular fruit body (more on a further two fb's still on the trunk) which suggests that it's been present in this tree for a significant period. .

    We reduced the canopy in November 2010 to try & protect it from wind load with a further reduction planned for next year (2015). Nature has beaten me to the drop with this one Or perhaps whatever we'd carried out previously and had planned was never going to be enough anyway ? .

    I believe the Collybia played the primary role in the tree failure here rather than the heart decaying brown rot of Fistulina, with the roots significantly decayed. .
  7. David Humphries
    Second one (which I'm more dissapointed about) was a fine Veteran oak which had decay issues with Collybia fusipes & Fistulina hepatica. .

    lost a couple of sizeable oaks during the last 24hrs in the tail end of Hurricane Gonzales. Both with seperate decay issues. First one was a turkey oak being digested by the white rotting Ganoderma resinaceum at its base & Fomes fomentarius up the trunk into the scaffolds. It was probably inevitable that it was going to go over at some point but a planned reduction early next year may have kept it standing for a bit longer. .

    No one said you you did, but in order to keep threads of this nature civil, it is necessary to delete posts that are by definition inciting the issue further. It's quite clear that the alleged behaviour is something that has got certain people's blood boiling, but we can and will not let the forum drift away from its core set of rules. With respect, there are vey few who realise how much time is put in (voluntarily) to help to moderate the site and keep it running as a civil and enjoyable forum. .

    I'm deleting the posts because one of the main rules of the site is being broken. There is absolutely no name and shame on this site. If you don't like that, I suggest you go elsewhere. Hopefully this problem will resolve itself for the opening poster. .

    The twisted section that's dead may simply just have it's specific root connection gone/dysfunctional. Which may be associated with the torsional force at the base of the tree putting too much compressive force on that root or it could be an abiotic/mechanical reason for the root failure . Either way I'd imagine that there's a dead root at the base of the section that's dead. Ps, do you mind, I'm trying to watch the Chelsea game .

    One and the same, just wear different outfits at different times of the year. I'd be willing to wager that no one has seen Herr Mattheck in the same room as Santa Claus ? .
  15. David Humphries
    Ha, not my reasons Pete, some fella called Claus .

    Helical growth of wood fibres are formed by a torsional twisting force. (wind load for example) Ok if the force stays the same but can unravel like a braided rope if the force becomes opposing which can occur if neighbouring trees are removed and the twisted tree becomes wind loaded from a different direction it's not used to. .
  17. David Humphries
    Yep, Perenniporia fraxinea. Nice shots .
  18. David Humphries
    sad fatality due to strong winds in the heart of London today. My thoughts to the deceased and the family. Woman killed by falling tree in London during UK storms | UK news | The Guardian .

    Hello Jeff I think it's likely to be Perenniporia fraxinia Worth taking a sliced wedge out of the rim edge to have a look at the felsh & tube layer. These features would help to determine the Id from Rigidoporus ulmarius (which can look similar) Perenniporia fraxinea creates a white rot in the wood volumes it infects, which degrades the lignin within the wood. This can lead to an infected tree collapsing at the basal region. That's the bare bones of it, but probably best not to take someones say so off the interent, it's always prudent to take professional advise from someone who has seen the tree in its context. Trees naturally decay as they age, but with appropriate management (where applicable) can be maintained to keep their aesthetic & ecological place within their environment. I manage a number of (reduced) trees that have Perenniporia .

    we've sourced some 15mm thick (heavy) dimpled rubber matts which were surplus (free) from an Ice rink, we intend to fit the whole flooring of the shed out. Will help with insulation and grip. .

    Not one of mine Kevin, up in Suffolk near to home. Inspection regime in place, but unless carried out at the same time as the fruiting, I think it would be difficult to identify & appraise If it was a roadside limb I would feel inclined to make contact with the land managers and report, as I've had dialogue with them in the past. .
  22. David Humphries
    Ooh err, that's for an entirely different thread Kevin .
  23. David Humphries
    Looks to be Confistulina, which is the anomorph of Fistulina hepatica - the beefsteak .
  24. David Humphries
    Bravo ! .
  25. David Humphries
    have to say I wasn't confident with my guess on that, good one Ben Indeedy, the wrinkled peach it is .
