  1. I think the first image are different stages of the slime mould Fuligo septica.
  2. I thought it was a very good webinar, the three panellist spoke well and John compared it with skill and panache ☺️ Some of the questions were a bit lame mind 😉
  3. Grifola frondosa is an unusual association with birch. I've noted it on other tree species (Robinia, hazel, cherry) as well its main host (oak) but don’t recall seeing it with birch. Although I have read that it can be a host association, and have seen a record of this. Do you know if there evidence of it being G. frondosa? Just interested. If it is, then it is likely to be evidence of root dysfunction and associated white rot decay of some/all of the roots of the tree, possibly caused by root fracture via a strong wind event or below ground damage from utility excavation. Has the tree been tested in any way? Visual assessment during root excavation, decay drill, pull testing? Again, just interested in the tree inspectors methods.
  4. Looks like a slime mould - false puffball, (Enteridium lycoperdon) Feeding on dysfunctional wood volume.
  5. Ta, most are from files, couple of them more recently.
  6. You've been tango'd ! Orange....ish fungi L. sulphureus I. hispidus F. pinicola P. adiposa T. ferruginosa Slime mold A. aurantia Bacterial slime flus Cheilymenia spp R. epindendron C. perennis G. sabinae L. aurantiacus F. hepatica S. scutelatta A. muscaria var formosa S. aurantiaca T. mesenterica F. velutipes C. viscosa P. aurantiorugosus
  7. The picture is of the Dexter Elm in 1894 Massachusetts, controlling Gypsy moth
  8. Thought you’d find it of interest. 🙂 I’ll pop back later in the year to see if there are any localised bleeds.
  9. Fine image Ben, great capture of colour and morphology 👍
  10. woodland beech possibly 70 years, this was a third order branch.
  11. Again at Burnham Beeches.... Brown rot and white rot at two ends of the same short beech wood volume. Fomitopsis pinicola (red banded polypore) and Pannellus stiptica - (bitter oysterling)
  12. Interesting question. Why do you ask and what do you think are the most important fungi to know? Any knowledge or experience of ones you’ve seen on and around trees? Thats a good starting point.
  13. Hello David Sarcoscypha sp. either ruby elfcup (S. coccinea) or Scarlett elfcup (S. austriaca) spore size under microscope needed to determine which one.
  14. I couldn't really comment on this tree without seeing the whole tree in context to its surroundings and the condition of the crown and twig extension growth. Anecdotally I've had oaks with decades old associations with dryadeus basal colonisation stand through significant storms, I've also had trees blow over in high winds with dryadeus. Tree vitality and exposure is key.
  15. One of I’ve seen recently at Epping Forest. 🤔
  16. https://www.bbc.com/news/uk-england-hampshire-51355369
  17. Psuedoinonotus ‘dryadeus’ but i think that’s what you meant?
  18. a little variable in surface colour but not unusual to be dark brown (slightly reddish) towards maturation. If in doubt always worth cracking open to look at flesh and tubes 👍
