  1. Anomorphic form of Fistulina hepatica rather than the more common telomorphic form.
  2. Yes, Meripilus. Tree is likely to be right royally fuched ! Examination would be needed to confirm how far the roots are compromised. The vascular columns ‘look’ sound but it’s how they connect to the roots will be key. How was the crown looking? Any fruit bodies away from the tree out on the roots?
  3. I can’t answer that for you, without assessing the tree in the flesh, too many variables.
  4. A slice of the fruit body showing the flesh and tube layer would make identification a bit clearer.
  5. Ganoderma species I would of thought. Perhaps G. resinaceum
  6. Tree Fungi colonisation & decay LTOA.pdf Thought members may be interested in a presentation I gave a few months ago to the London Tree Officers Association on fungi.
  7. Had my pair for 6 years (although don't climb these days) found them to be hard wearing. Getting a few little holes now so looking to buy another pair soon.
  8. Chicken would be brown rot more targeted at the old heart wood, Merip - white rot targeting roots.
  9. Been busy 😄 looks like chicken to me to me but not a good angle shot to be sure. Any other images Mick?

  11. Which is a little confusing as it’s technically a polypore and doesn’t have gills. Albeit the pores are elongated and mazelike.
  12. Looks to be a desiccated Phaeolus schweinitzii
  13. Just once, a few years back. play from about 3.40mins for tracked mini crane. would definitely use one again for the right job.
  14. I would suspect a young developing Ganoderma resinaceum
  15. Yesterday Mick. HC leaf miner colonisation pretty variable across our sites in London.
  16. Horse chestnut (which was pretty much upright 30 years ago) with progressive lean over pond. Recent shear crack, dropped a bit more. Reduced to mitigate the failure, good for another 10 years, will bush out again. Provides good shade for the fishies. Dragged out all the timber and brash with a pull line, pulley & landrover.
  17. Hello David, only just seen this. Have you ruled out Spindle shank (Gymnopus fusipes) ?
  18. http://www.ancienttreeforum.co.uk/wp-content/uploads/2017/04/Trees-a-lifespan-approach-Nev-Fay-et-al.pdf
  19. bejeezus its taken an age, but finally stuff starting to pop up here and there at work. Laetiporus on cherry Amanita fulva on oak roots Fuglio septica on oak Gymnopus fusipes on oak roots Amanita rubescens on oak roots Volvariella bombycina at the base of Horse chestnut
  20. Possibly Rigidoporus ulmarius. Cut a slice/wedge out and have a look at the flesh and tube layer. If it's white flesh and thin orange/cinamon tube layer then it's likely to be R. ulmarius. if the flesh is dark brown then likely to be Ganoderma species.
  21. Remains a major issue from our experience. Lost a large massaria infected branch this morning that landed on and damaged a wooden fence. Gave a passing member of the public a bit of a jolt. The guidance documents published in 2013 are currently under review by the LTOA Massaria working party and will be updated and re-released in the next few months.
