  1. Perenniporia fraxinea would be a good host specific shout but I’m thinking I wouldn’t rule out Ganoderma sp for this one. Did you take a slice of the flesh and tubes to help with the Id?
  2. Could be just mold feeding on the pine sap Rich
  3. Jersey Tiger Moth (Euplagia quadrripunctaria) Stretching its wings a little further afield. This one at the base of a toilet door in north London.
  4. Forest Research update and distribution map https://www.forestresearch.gov.uk/research/elm-zigzag-sawfly-britain/
  5. Are you thinking that is two different Ganoderma species Will? Gonna be a lot of white rot in there.
  6. Turkey oak carcass with Ganoderma resinaceum, Volveriella bombycina and Fomes fomentarius.
  7. Liked that Reg, really refreshing to see a tree working man out just enjoying the vastness and natural splendour of such a great ecosystem. Narration and editing of the drone footage made it an enjoyable and interesting watch. Very jealous of your experience.
  8. Possible zigzag elm sawfly (Aproceros leucopoda) on one of our New Horizon’s https://www.woodlandtrust.org.uk/blog/2018/06/zigzag-elm-sawfly/ Have sent in a report to tree alert.
  9. Short article in Pro Arb about the teams findings. http://proarbmagazine.com/urban-trees-absorb-carbon/?platform=hootsuite “The team found that Hampstead Heath stores up to 178 tonnes of carbon per hectare, which is catching up to tropical rainforests that contain on average around 190 tonnes of carbon per hectare.”
  10. You try chasing a bag of air around for 90 minutes in that heat Going to to be more scores like this in 2026 when they open the finals up to 48 teams. Plenty of minors to batter then. Too early to rate England yet as they haven't been up against a decent midfield yet.
  11. Fomes fomentarius on pond side poplar Ganoderma resinaceum on roadside oak developing over a week Rigidoporus ulmarius on woodland horse chestnut
  12. fairly uncommon to find OPM by themselves. They like company.....
  13. Big Lombardy split apart in central Cardif https://www.walesonline.co.uk/news/wales-news/live-updates-huge-tree-falls-14787840 Would be interested to know what the “fungal activity around the base of the tree” was. Tree surgeon who inspected the tree in November 2016 recommended removal. Wondering what the time line and priority was. pictures by shoko doherty
  14. Few interesting finds over the last week or so. Dichomitus campestris dead oak branch Hampstead Heath Hericium chirratum dead Horse chestnut limb HH Ganoderma resinaceum red oak HH Radulomyces molaris dead oak branch HH Cerioporus (Polyporus) squamosus declining Horse chestnut HH Stemonitis fusca dead pine trunk HH Fomes fomentarius red oak HH Ramaria sp (possibly R. stricta) dead Horse chestnut branch HH Amanita fulva with Sweet chestnut Greenwich Park
  15. Arie Haan's rocket past Sepp Maier in '78 got me thinking that this football malarkey was a bit good. filled out a fair few pages of that years Panini sticker handbook .
  16. No fruiting bodies of Kretzschmaria on this sample.
  17. Treeworks are based in Bristol Gary but they deliver 'most' of their seminars in London due to venues (Kew, Linean Society etc.....) and closeness to the mainland (friend of mine 'popped' over on Euro Star from Belgium for the day just for this seminar) I can't speak for Neville, but if there is enough interest t'up north then I'd imagine it would be an option. Suggest you contact the Treeworks Seminars team [email protected]
  18. Fascinating study day held at Greenwich University and out in Greenwich Park out among the veteran Sweet chestnuts with talks and field demo's looking at soil biology, soil profiles, compaction, poor drainage, foliar applications, mulch, biochar and options for managing chestnut Ink disease (Phytophthora cambivora & cinnamomi) as well as looking at Flagellated Spores ! even had time to take in the obliging fruits of the local mycorrhiza Nev Fay has suggested that this workshop may run again if there is enough interest. Alternatively this years AA conference is focusing on trees and soils where a lot of this day will be run again.
  19. What led to me looking back on this particular stump is that on passing recently one of the retained branch stubs has failed and exposed the level of decay and habitat inside the wood volume. Full of beetle galleries and as light as paper.
  20. Observations of sequential and overlapping colonisations by different fungal fruiting bodies and decay in a standing dead wood volume over 10 years. case study: Fagus sylvatica - European beech This roadside beech tree presented with declining leaf vitality during inspection in 2008. The giant polypore (Meripilus giganteus) was suspected as having colonised the dysfunctional root area. The tree shut down completely and was reduced in 2010 being left as dead standing wood volume for habitat. 2010 The first two fungal species noted pre reduction were Meripilus giganteus around the base of the tree decaying the roots and Chondrosterum purpureum colonising the stem and lower scaffold branches. March 2012 Coprinellis (Coprinus) domesticus with Ozonium at the base of the tree November 2015 Arbortiporus biennis (unusually found here at height) Gymnopilus junonius October 2016 Ganoderma australe 2016-2018 continued fruiting of Meripilus giganteus, Gymnopilus junonius and Ganoderma australe I intend to add further observations of fruiting as and when noted.
