  1. ........additionally, ofcourse we shouldn't be closed minded to decay related stem failure being associated with more than one decay culprit as with this 'Acer' which failed due to the white rot of P. squamosus but also facultative decay of Kretzschmaria deusta. .
  2. Jules, perhaps this is the nub of it. Your observations are on two of the weakest species for compartmentalising decay, particularly intense white rot like P. squamosus. Also Tilia can be placed within that group. My field observations back that up but also suggest that stronger compartmentalisers (beech/oak/elm etc.....), can and do live with P. squamosus colonisations for many years. So perhaps its parasitic leading to failure of certain tree species and more weakly parasitic/saprophytic on wounds and dead wood to varying degrees in other tree species. No one hat fitting all. The Aesculus below is quite obviously of the former persuasion....... .
  3. Liked the story telling of the day, but found it too long. Too much branch cutting. Nice site context before and after. Looked a tidy and efficient job. Why were they removed James? .
  4. Hello New Boy. Are you sure it's a silver birch? The brackets 'look' like one of the Phellinus species, possibly Phellinus igniarius Have a look at the fungi directory on the main Arbtalk website for images for comparison and information on decay type .

    <p>Hello Darran</p>

    <p> </p>

    <p>Looks a bit more like Bjerkendera adusta (the smokey bracket) to me</p>

  6. I wouldn't necessarily agree with this Jules. Although both Schwarze and Butin appear to suggest that the saprophytic nature of P. squamosus on dead stumps and other dead wood volumes is not as common as its supposed Parasitic nature, I think this is perhaps their observations from in-vitro studies and from a European (specifically German) field perspective. My own observations (though I'm not suggesting that fruiting is definitive proof) is that the species is very much a sap wood exposed strategist and that it 'parasitises' dead/dysfunctional volumes (wounds). It does have the ability to extend through the damaged xylem/sapwood at a relatively slow rate but more often acts as a saprophyte. The above is partly why I 'categorised' it as Saprophytic on the Arbtalk Fungi app. Perhaps not strictly a scientific view but one brought together from exploring a number of texts from the above authors (also David Londsdale) and from witnessing a significant number of examples in the field across a variety of tree species and situations. I don't apologies for the gratuitous level of images below as they give context to the post. All are either on completely dead standing trees, old pruning and/or storm damage wounds and stumps/detached logs. .
  7. The mad Axeman of Hampstead captured half way up a copper beech..... .
  8. Interesting looking at the lists of host specific pests and seeing what's not listed compared to what's here now. OPM etc.... .
  9. We run the Senna 10's as well, can't fault them Reminds me that I need to buy another couple. .
  10. Due to it growing as a joint canopy with associated root form and adaptation to that particular load and it also being used to a predominant wind direction but sharing the load when the wind is from a different direction. Nothing there to share that load now. Wind be a strange force of nature and unpredictable beast at the best of times. I see it often on dual carriageway widenings, big trees that had shelter with in a woodland edge now exposed to different load and tipping over. Now bugger off, I'm trying to watch the new episode of Black Sails ! .
  11. Steve, I can see that the remaining line has been reduced in the past. Is it staying put or is it coming out as well? If it's staying put, is it being reduced due to its increased wind load due to its neighbour having been removed? Do you know if also has Kretz? .
  12. Quick answer........Yes Mix of images, graphs and text appeal to a wider audience .
  13. Oops ! What a silly place to park a car .
  14. We bought one about 10 years ago and persevered with it for a while. But it wasn't very useful in our experience. It's been hanging up in the shed on the same peg for about 7 years http://arbtalk.co.uk/forum/climbers-talk/3073-rattle-wedge.html .
  15. Thanks for the update You must have been sucking an aniseed ball in the previous couple of hours prior to smelling the bracket .
  16. Beech which died in 2004 (1st image) we then monolithed and coronetted in 2008 (2nd, 3rd & 4th images) Still standing today and not changed much on the outside in 8 years.........(last 2 images) Had an entomologist survey it as part of a dead standing tree study a couple of years ago and it's now host to an interesting array of creepy crawlies and fungi .
  17. Dagnabbit ! Thought I'd I'd got rid of all the duff early ones You dishonor all my endeavours and good intentions Bullman !
  18. Any one tried this type of method for anchoring young trees............have any thoughts? Biodegradable Tree Anchor - Brilliant Little Planet .
  19. My seat travels far and wide Mr Harrison ! None of those listed in the below thread for sure...... http://arbtalk.co.uk/forum/fungi-pictures/49997-meripilus-giganteus-giant-polypore-its-host-range.html How about looking at coniferous ? Yew, Pine ? .
  20. If you lay it on its side the brackets will just go tropic to its orientation and continue to sporolate in its new position like this Trametes below ....but you know that .
  21. Stumperies are certainly in vogue with Gardners both large and small scale. Chelsea flower show had a small urban garden example last year created by Capel Manor College Ickworth National Trust is another fine example on a larger scale. Our own at work is developing nicely with interesting fungi popping up on them. http://arbtalk.co.uk/forum/ecology/58756-stumpery.html .
  22. I think it's a good shout Chris, nice set of shots Not one that I've come across often. Only 74 UK records which makes it a red data list species Predominantly noted on Salix and occasionally Poplar. Species data - British fungi Did you smell it? T. suaveolens has a relatively strong aniseed odour Might be one worth sending into Martin at Kew for confirmation and General interest. .
  23. No accident about it, t'is an art don't ya know One or two in amongst this compilation........ [ame] [/ame] Can't take the credit as others from the City of London at another site developed the technique after a significant number of veteran trees were killed during a large fire at a site in Kent during the 90's http://www.treeworks.co.uk/downloads/8%20-%20Coronet%20cuts%20&%20retrenchment%20pruning%2017%20April%202003.pdf .
