  1. 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.
  2. 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.
  3. 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.
  4. 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 ?
  5. 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.
  6. May just be something like Hypholoma rather than oak poly if they are all the same and have gills
  7. Do the fruit bodies behind the main specimen in he last image look to have gills?
  8. 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?
  9. Looks like scale insect https://arborjet.com/problems_solutions/scale-insects/
  10. Hi, after half hour of trying to figure out how to delete my profile, I am left angry and fustrated. No option to delete, no tranparant available info. 

     

     

  11. Enteridium Lycoperdon, the false puffball
  12. Interesting visitor to the Heath at Hampstead few days ago. crested Caracara Flew off from London Zoo and is still at large
  13. If it’s a perennial bracket type, worth considering Rigidoporus ulmarius
