    What tree species were they near?
  2. David Humphries
    if there’s a slight pink tinge to the base of the stem (pink hyphae) then it’s likely to be collinitis, if there isn’t any pink, then probably granulatus
  3. David Humphries
    probably a trichoderma mould species
  4. David Humphries
    If pores, then they may be one of the mycorrhizal bolete species like Suillus collinitus or Suillus granulatus.
  5. David Humphries
    Can you ask your friend if they had gills or pores Rich?
  6. David Humphries
    Xylaria polymorpha (dead man’s fingers)
  7. David Humphries
    A slime mould species Mike, did you lick it? 😁 possibly one of the Physarum species.
  8. David Humphries
    Might be an earth fan species, compare to one of the thelophora sp
  9. David Humphries
    Its not Aurantiporus, its either going to be Ganoderma resinaceum or Perenniporia fraxinea. I think its likely to be the latter. Ideally a wedge of the flesh and tubes would be needed to confirm. Also look for spore deposit on the leaves or webs. Ganoderma will be cocoa brown, Perenniporia will be cream/white.
  10. David Humphries
    laetiporus sulphureus
  11. David Humphries
    looks good for Hydnellum sp, what was it growing with and where abouts?
  12. David Humphries
    Maybe Sterium hirsutum (Hairy Curtain Crust) for the last one?
  13. David Humphries
    Unusual but I’ve seen hispidus at the base of trees before, they don’t read the books 😄
  14. David Humphries
    Probably Inonotus hispidus (Shaggy polypore) Depending on the level of occupancy around the immeadiate vicinity of the tree, I suggest you have it assessed by a professional Arborist that has access to the knowledge and equipment required to undertake assessment of potential basal decay and any associated stability issues.
  15. David Humphries
    looks like Abortiporus biennis growing on the dead roots.
  16. David Humphries
    Parasol (Macrolepiota procera)
  17. David Humphries
    Yeah possibly, any shots of the flesh and tubes? worth considering Postia stiptica as a look a like to compare
  18. David Humphries
    I suspect this is Ganoderma adspersum. The dark brown flesh in the 3rd image rules out Phellinus or Fomes. The white surface in your 3rd inage is a feature of Ganoderma, whereas the under surface of Phellinus is a tan brown colour. I also think I can see cocoa coloured spore on the edge of the cobweb in the 3rd image. Do you have a copy of the AA Fungi on Trees photographic reference book? On page 77 in the section on perennial fruit bodies, image 4 (going clockwise) shows a tired bracket of G. adspersum that has a surface like your old fruit bodies which also shows a wedge of the flesh on top which is a close match to your 3rd image. Hope you find this helpful.
  19. David Humphries
    Yeah, looks like Abortiporus to me. the pores bruise like that
  20. David Humphries
    I think it might be early forming Abortiporus biennis. will be worth going back to it in a week or so to see how it develops. did you take a slice to see within for flesh and tubes?
  21. David Humphries
    Might be worth looking at the soil for contamination, trowel out some volume and have a smell. Could be that oil, diesel or some other chem has been ‘accidently’ allowed to escape into the soil horizon in that part of the root zone and killed off the roots leading to sectional dysfunction/dieback. What’s the history of the site use in that particular area? How long has that street light been there, looks relatively recent.
  22. David Humphries
    Hi Rich, hope you’re all well mate? on juniper it’s likely to be Gymnosporangium sabinae its a species that has dual tree host, juniper is the primary host and and pear is the secondary host.
  23. David Humphries
    Fine example of geotropism with this Ganoderma on a fallen oak
  24. David Humphries
    Any images of the failures?
  25. David Humphries
    I’d tend to agree that graft points are uncommon failure points in beech. We looked at some copper grafts in 2016 and didn’t find much to be alarmed about.
