    Difficult to be sure at that resolution. A clearer image of the pores would be useful. They could be I. hispidus, but wouldn’t rule out Cerioporus squamosus.

    Looks likely to be a soil/root issue on the roadside of the tree, with associated branches becoming dysfunctional. Trees will eventually struggle in an urban grass environment. If the tree is valued consider losing the grass from underneath the canopy and increase the width of the mulch and (if used) reduce the use of fertilisers/weed killers around the trees.

    Can you show us images of the whole tree in context with its surroundings? Is there any recent history of soil change around the tree ?

    This is a resupinate crust fungi, something like Basidioradulum radula (toothed crust) It is a saprobic fungi, feeding on dead wood and not the primary reason for the tree declining. It is spreading in to dysfunctional wood. There will be another agent of decline occurring, like a soil issue (successive drought, water logging, compaction, contamination) Or an airborne pathogen. This in turn will lead to sections of the tree shutting down and then possibly the whole teee dying.

    May just be something like Hypholoma rather than oak poly if they are all the same and have gills
  6. David Humphries
    Do the fruit bodies behind the main specimen in he last image look to have gills?
  7. David Humphries
    Red colour on the pore surface is likely a parasitic fungi attacking the surface of its host (what tree are those associating with?) The last be may well be Buglossoporus quecinus if it’s with oak and defiantly is a polypore and not a forming mushroom type with gills or Bolete type with pores? I’ve seen oak poly split like this. Can you remember which month yo photographed that one?

    Looks like scale insect https://arborjet.com/problems_solutions/scale-insects/

    Enteridium Lycoperdon, the false puffball
  11. David Humphries
    Yep

    Interesting visitor to the Heath at Hampstead few days ago. crested Caracara Flew off from London Zoo and is still at large

    If it’s a perennial bracket type, worth considering Rigidoporus ulmarius

    Pollen cones

    Subtle 🙂

    Hair Ice, nice find ! Hair Ice WWW.METOFFICE.GOV.UK Hair ice is a rare type of ice formation where the presence of a particular fungus in rotting wood produces thin strands of...

    2021 has been a cracking year for me regarding all things fungi. Found some amazing species, co-authored a book, gave some online talks & got a microscope to take identification a bit further down the road. 2022 should open up a whole new microworld of geeky myco-fascination 😁🔬 Below image includes a few of my favourite finds this year from Hampstead, Cambridgeshire, Norfolk & Suffolk. Some already known, some new to me. Species l-r are Silky rosegill (Volvariella bombycina), Summer truffle (Tuber aestivum), Eyelash fungus (Scutellina scutellata), Bilious Bolete (Rubroboletus legaliae), Earpick fungus (Auriscalium vulgare), Fluted Birds nest (Cyathus striatus), Golden Scaly Cap (Pholiota aurivella), Parasitic Bolete (Pseudoboletus parisiticus) & Scarlet Elfcup (Sarcoscypha austriaca) Further images can be seen @ https://www.instagram.com/tree_myco_man/

    Stump puff balls (Lycoperdon pyriforme)

    Ganoderma resinaceum
  21. David Humphries
    ‘If’ it’s Gymnopus junonius, it’s is a saprotroph that will be taking its sustenance within dysfunctional areas of the damaged wood volumes (probably the roots) It will be a slow process of degradation. If the tree is in decline due to more than the root damage (other disease/dysfunction) the fungi will be part of the succession of the ongoing decline.

    Difficult to be sure when the specimens are starting to over mature. Easier when they are in early development. host (although found associating with a wide range of broadleaves) Cap colour (although a little faded here) No cap scales (although they may have washed off) Gill colour Gills are crowded Gills possibly adnate remnant ring on stipe and a hunch 😁
  23. David Humphries
    A slice of the bracket to show flesh and tube colour would help with identification, also an idea of spore colour is useful. Worth considering Rigidoporus ulmarius and Perenniporia fraxinea
  24. David Humphries
    Maybe worth considering Gymnopilus junonius
  25. David Humphries
    Brown flesh, white pore layer. Ganoderma species, possibly Ganoderma adspersum/australe
