    APC is bang on, this is Armillaria mellea Jon The give away is the annulus/ring on the stem Try to look out for these other features when trying to track down an Id, things like the gills, stem type, ring, spore colour, host........... If the hazel is in its death throws then honey fungus rhizomorphs/mycelium has probably been through its Biotrophic parasite stage here, attacking a weakened host and is possibly purely into being a saprotroph now hence the mass fruiting. Might want to consider other susceptible species in the immediate area specifically ones that are in a spiral of decline. .

    I've never felt that trees (in general) offer themselves as perfect biological structures each and every time we change their form. Surely the vitality of their dynamic mass is more important than subscribing to text book direction in terms of where they should be wounded/pruned. One of the most encouraging moves forward here in the UK was at the review and update of the latest British Standard on Tree work Recommendations (3998: 2010) where annexe C (normative) 'crown management - specialised practices' talks about leaving stubs for the development of epicormic or dormant buds. .

    Dregs of yesterday's Les Dauphins Cotes du Rhone for dinner Now moving on to a wee glass of țuică .

    That entirely depends on what species of fungi it is Chris and then on the extent of associated decay. Did you 'test' the region of fruiting to ascertain the extent of decay? .
  5. David Humphries
    Pretty desiccated Did you look below it to determine if it has the remnants of pores or gills? A guess would be Ganoderma resinaceum. But it could quite easily be Meripilus giganteus. But nothing really in the shots to be sure about. .

    a few desiccated pestle puff balls and Armillaria on a dead cherry..... .
  7. David Humphries
    more mycorrhizal fruiting..... Lactarius circellatus - (hornbeam) milkcap, Amanita rubescens - the blusher & Amanita phalloides - the death cap, here on lime or possibly hornbeam .
  8. David Humphries
    One of the mycorrhizal Russula species possibly R. exalbicans .
  9. David Humphries
    Do you have a link to it? I've only seen the pilot RDL assessment regarding the Boletaceae Is the full 2013 Fungi RDL now available? .

    Thanks guy/sean. pretty cool to be influenced by & share the results with like minded arbs across the globe. we're getting there ! .
  11. David Humphries
    That's a great link. thanks for sharing .

    Interesting Mark, though I have not come across Grifola on Sweet chestnut myself. I've read that it does associate with Sc and I believe maple, hornbeam, birch, elm and beech as well as it's usual host of oak (Ryvarden & Gilbertson) They also mention that it can be found with conifer also. Heinz Butin suggests that the Sc association is a Southern European one. Where abouts is yours? The FRDBI data base also lists it with sorbus, hawthorn, hazel & ash. It manifests itself as a white rot in the upper root zone and lower stem and mostly noted in various texts as fruiting at ground level but I've come across it fruiting up on the trunk a number of times. Tony put up an interesting thread on Grifola a couple of years back, worth a look. http://arbtalk.co.uk/forum/fungi-pictures/33528-grifola-frondosa-assessment-thermo-twist.html .

    What's the host? Any other shots? Cheers .

    The unmistakable yellow flouresence of Armillaria melea, here out in grass a fair way from the nearest tree. Perhaps some dead roots where its active. .
  15. David Humphries
    some more Amanita muscaria these are the first I've seen fruiting in London this year, but I know they have been out & about elsewhere for a while now. .
  16. David Humphries
    Mycorrhizal birch associates - Amanita muscaria and Russula sp (possibly R. parazurea) and also a couple of Armillaria fruitbodies throwing some saprotrophic love in to the equation .
  17. David Humphries
    An interesting root crown with Grifola fruiting from various locations .

    a worthy thread resurection. although heavily colonised, this branch didn't take a lot to pull it off. Oudemansiella mucida - Porcelain fungus - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists .

    one of my favourite oaks this one. small, but holds its own in the treescape. .
  20. David Humphries
    The tree has put on a fair bit of internal epicormic and foliage at the peripheral branch tips, but the feathery end weight has been reduced to a more compact form which I believe has reduced the chance of branch snap considerably. .
  21. David Humphries
    been a little pre-occupied with work things don't you know Shots of before, during and an update from today .
  22. David Humphries
    Not seen many images coming from stable of late Sean. Camera issue or time? .
  23. David Humphries
    The white rot of both the Ganoderma & Inonotus was evident throughout the tree. It could have stood for a few years more, but we were not particularly confident that the canopy branches would have held out much longer. Stump is to be ground out and the planting pit will have a new replacement (not ash) in due course .
  24. David Humphries
    Confident that we were not destroying current occupation the team carefully removed a few sections that we will resurect & use as habitat in other local trees. Then crash matted the rest of the branches. Trunk was then felled. .
  25. David Humphries
    Today was the day for its change of orientation......... brush stripped out first, then under the direction of our sites licensed bat worker we inspected the woodpecker holes, cavities & bark fissures .
