    Last couple of days at work in north London, the rains have kick started the season

    This is a young developing annual fruit body of Ganoderma resinaceum

    Might be Aurantiporus fossilis, did you manage to check the flesh and tube layer?

    This species of fungi is indicative of an area of dysfunctional wood volume. It will not have caused the dysfunction, but will create a brown rot which will take advantage of the available dehydrated wood. The dysfunction is likely caused by an environmental factor producing a suboptimal condition for the tree to thrive. If that situation continues then the outer living shell of functional wood will diminish and not provide enough structural wood to withstand load and force which may end with whole or part tree failure.

    Lovely Laetiporus example
  6. David Humphries
    Laetiporus 👍

    Last couple of days at work (Hampstead Heath, north London) Laetiporus on dead oak, Meripilus giganteus on live beech, anamorphic stage of Fistulina hepatica on live oak, Neolentinus lepideus on conifer sleepers, Inonotus hispidus on live weeping ash, Gymnopus fusipes on live hornbeam, Cerioporus squamosus on dead something or other & Fomes on dead oak branch.

    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 ?
  11. David Humphries
    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
  13. David Humphries
    Do the fruit bodies behind the main specimen in he last image look to have gills?
  14. 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
  18. 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
  20. David Humphries
    If it’s a perennial bracket type, worth considering Rigidoporus ulmarius
  21. David Humphries
    Pollen cones
  22. David Humphries
    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...

    Yep

    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/
