  1. Certainly Ganoderma but difficult to ascertain which one between applanatum/australe without looking at spore under a microscope. It 'looks' to have the morphological characteristics of applanatum to my eye. .
  2. Lets hope more people make the time and actually bother to read it. Its not that onerous. Pretty important document that should be adopted by everyone involved and interested in managing the urban forest .
  3. Chris, there's only been a relatively short print run so far as it was designed as a document to download as pdf. I have a few hard copies but they're intended for my Director and other management. If one becomes spare I'll give you a shout. I don't think that there is any intention to extend the print run. .
  4. At the House of Lords for a Tree event yesterday and bought a bottle of 10 year old HoL's speyside single malt by Gordon and Macphail of Elgin Very nice ! .
  5. The table on page 63 of the report gives a comparison of where London sits against other cities from North Amercia and Europe in terms of canopy cover, carbon storage, carbon sequestration, pollution removal etc .
  6. 18 months on from the project, the report was finally launched today at the House of Lords. The report can be downloaded here.... http://www.forestry.gov.uk/pdf/LONDONI-TREEECOREPORT151202.pdf/$FILE/LONDONI-TREEECOREPORT151202.pdf An interesting mix of speakers today, but none more so than Lord Framlingham (continuing his appeal made at the Barchams Big Barn seminar and the AA Conference) for there to be a stand alone Tree Minister, urging the Secretary of State for Environment and Rural Affairs (Rory Stewart MP) to take up the challenge to press government to create the role. .
  7. Would think he first ones are the mycorrhyzal Xerocomellus chrysenteron (aka Boletus chrysenteron, Xerocomus chrysenteron) The large bracket on the ash probably Perenniporia fraxinea .
  8. I replaced the slice of the Ganoderma in this particular instance Jules, no real reason as to why. Often, if the mycelium/fruit body is still active, the slice (void) can just close up when it puts on another incremental pore layer as in the Perenniporia fraxinea images (1-3) & the Fomes fomentarius images (4-5) The Fomes shots were taken 3 years apart (2008-2011) Yellow circle shows the original slice .
  9. Certainly looks like it Jon Has its usual hosts but I don't think its surprising to find it across a wide range of tree & shrub species. Not seen it on Euculyptus before .
  10. ......knife through butter good shots Lime that we winched over that was heavily colonised with Kretzschmaria [ame] [/ame] .
  11. Ganoderma species on a London plane (we've not carried out spore sampling/measurement to determine either applanatum or australe) First 4 images from last December, last one from earlier today. The cut wedge clearly shows the dark brown flesh. Interesting watching the bracket develop over the space of the year. .
  12. We seem to be doing it less than we were back then, but still have it our bag when we feel the tree and its environment merit it. [ame] [/ame] .
  13. Close, but sean knows I'm strictly a Canon man .
  14. It was great to see you at the Kew seminar Sean. Can't believe you chose to sit next to Jeremy Barrell though Another big step forward in your rehabilitation that must have been really hard decision for you to commit to. A big challenge for you no doubt Proud of you mate Hats off to your friend who drove you up from Bristol, that was really good of him. Catch you again soon hopefully .
  15. I think perhaps there's a slight confusion here Guy, fracturing branch ends (as opposed to coroneting) is where the adventitious sprouting can be stimulated. First two images Coronetting is purely about aesthetics (mimicking naturally severed branches) and creating micro niche habitat for invertebrates etc..... and not concerning sprouting. Last image .
  16. Perenniporia fraxinea or Rigidoporus ulmarius. A slice of the flesh would help determine. The slight hint of orange around the top of the pore layer may suggest the latter. They would have been associated with decaying the base/roots of a large tree that would have been standing there at some point .
  17. Has a look of Bjerkendera adusta Which I have seen guttating .
  18. It does looks like Armillaria, but would need clearer images to determine between mellea and other Armillaria sp .
  19. It's actually not that recent, it was described by the Germans Wagner & Fischer in 2001 Pseudoinonotus dryadeus (Pers.) T. Wagner & M. Fischer, Mycol. Res. 105(7): 781 (2001) it's been slowly adopted since then, I only started getting my head around that fact a couple of years ago. (its even in Matthecks most recent work as Inonotus dryadeus) I think DNA sequencing found that it's not technically a true Inontus like hispidus or cuticularis. .
  20. You're welcome Owen, the interaction is a learning opportunity for us all. Psuedoinonotus is the new name for Inonotus dryadeus .
  21. I would think so, but possibly wait for Mr Croft's stamp of approval .
