    Thanks for posting the follow up image Will. What height was the stump at when you took that shot? The frustration of members around this level of tree removal is understandable as I. dryadeus is not known as an agressive fungal pathogen and I suspect a number of us may have predicted what the cross cut image may have looked like before you posted it. Obviously we don't have the context of the tree as you had prior to the decision was made to remove it. Do you have any other images of the tree prior to the removal? .

    Liberal use of 'midichlorians' Tom That tree was coming down to a monolith and was being held in place on the trunk by the back plate teeth as we didn't use the rubber savers. It stayed in place after we released the strap. Thanks for the advice, mate. Thought about using size specific ratchets, but just wondered how many users had considered or actually done this. .

    Bit too much wear on the buckles of my belts Mark .

    Thanks Mike Would you know if your clients used any particular supplier for Hobbs spares or used alternative straps? .
  6. David Humphries
    Our Hobbs is about 10 years old. The attachment webbing strap appears to be in good condition. Interested in whether anyone has considered or actually changed their original strap due to age or after impact ? My understanding is that as a material part of the device, the safe useful life expectancy is/should be 5 years? .

    Think this might work, but can't vouch for the photographer Smart Phone Apps for Arborists - buy now .

    Ain't there some old knot app out there you could use? .
  9. David Humphries
    Probably .
  10. David Humphries
    Based on the pore structure I would think the 1st is G. resinaceum and the 2nd on the cherry is an early developing G. applanatum or G. australe. .
  11. David Humphries
    I think it's prudent to be cautious on which species of Ganoderma it is. Only spore size under microscope will differentiate between applanatum and australe. The reiterative rooting looks interesting. I wouldn't be at all surprised if Kretzschmaria deusta was also colonising that side of the tree.
  12. David Humphries
    answered it in the main fungi thread earlier .

    some fine fruiting from random inspections at work today. Ganoderma resinaceum, Bolete species (maybe red cracking bolete), Fistulina hepatica, Collybia fuisipes , Podoscypha multizonata and Cyathus striatus (fluted birds nest) .
  14. David Humphries
    I think you are on the money with your suggestion. Worth taking out a wedge slice of the fruit body to look at the flesh and tube layer. This tends to helps with identification. .
  15. David Humphries
    A turkey oak with a significant long term colinisation of Ganoderma resinaceum It has absolutely no basal heart wood, but lots of vitality. First shot was taken before the first crude non BS: 3998 topping in 2003. Subsequent images are from a revisit in 2007 involving foliage and 1st order branch volume removal and the last images are from today. The tree will be receiving a further reduction, working it down toward a pollard. .

    Definitely worth a go, as I have seen it work, although we have found that its very difficult to get advantitious buds forming from the wounds/callous material....... http://arbtalk.co.uk/forum/ecology/51183-deliberately-wounding-trees.html .
  17. David Humphries
    Looks to be heavy reduction time now. If it survives, then that would be a bonus. If it doesn't, treat it as standing dead wood (monitor/re-reduce when required), which is as valuable an asset to biodiversity as the live tree is to aesthetics. Thanks for the update .
  18. David Humphries
    As above, saproxylic insect trap, someones carrying out an invertebrate survey. Some very nice volumes of brown decay in that oak, it will be festooned with creepys of all manner of shapes & sizes. or in a parallel universe this is by far the better answer .
  19. David Humphries
    I'm merely observing that beech 'can' regenerate, not that it can regenerate well/commercially. .
  20. David Humphries
    I'm not sure this is an entirely accurate fact Jules. I think it's a given that as a species it's not the choice of coppicers, but my observations suggest that it is capable of regenerating from large diameter stumps (12" stump in first 3 images) and I've also witnessed beech putting out epicormic growths from buttresses where there is basal decay on a number of different examples. .
  21. David Humphries
    Chris the first one is not Daedalea quercina, would think its more likely to be Daedaleopsis confragosa The last one is more than likely Ganoderma resinaceum. Too hard to say which of the other Ganodermas are applanatum or australe Although morphology appears to be very different between the two species, we've found that the 'tell tale' characteristics that you read about in the I'd references are inconsistent and that the only way to really tell is via microscopy looking at the spores which are of different size and structure. .
  22. David Humphries
    I would lean toward Megacollybia (Tricholomopsis) platyphylla Definately not Russula, and I think you would see the tell tale bleeding from the damaged gills if they were any of the Lactarius species. .
  23. David Humphries
    I would say the first ones are certainly Armillaria but without seeing the gills or stem it would be difficult to pin point which species. Worth considering A. tabescens (the ringless honey fungus) as that one is wholly saprophytic, and yours appear to be fruiting from dysfunctional volumes. Have a look at that one in the Fungi directory above. Try getting into the habit of turning one upside down when documenting them. Your shots are great but the devil is in the detail The second ones are from the Coprinus group, perhaps C. truncorum. It's very similar to C. micaceus and can only really be differentiated by looking at the spore, but your images seem to not show the mica (white powdery granules) on the cap surface that are the usual visual difference associated with the latter. .
  24. David Humphries
    Big Tree Pete, nice shots and work. How did you find it after switching codes after a while away? .
  25. David Humphries
    How can you not, when they fruit as handsomely as that. Don't think I've ever seen a single clump of multi fronded meripilus like that before. Is it fruiting off the roots of a tree out of shot, or an old stump underneath the fruitbodies ? .
