Oxyporus populinus.

looks like Fairy Ring Champignon, Marasmius oreades, Fairy Ring Champignon mushroom WWW.FIRST-NATURE.COM Marasmius oreades (MushroomExpert.Com) WWW.MUSHROOMEXPERT.COM Saprobic in grass, not having anything to do with the tree

Slime mold of some sort, quite a few with this yelllow plasmodial stage, if you return to it in a few days you might be able to see what it has developed into and ID it

Me too although name has been changed to fomitopsis betulina. another brown rotter, may just be acting saphrotically on the dead branches but more likely also colonising live wood as well

just on my way out, so not time to look properly but Oxyporus populinus is worth considering

Interesting; don't think our local TO would see it that way. When neighbours have carried out work on TPO'd trees i look after without permission (or proof of legal nuisance/ previously stated exemptions) they have always, at the very least, received a warning letter.

Yes it's just an explanation of the standard overhanging branches rule. i guess they put it in as standard to encourage people to talk to their neighbours before doing work but it's inclusion in a TPO app letter is, i agree, unnecessarily confusing. You're right that a TPO overrules this right to cut back to boundary

looks like hair ice. caused by a fungus on the wood 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 ice which resemble hair or candy floss.

Looks to have occluded quite a few wounds in it's time, entry will probably have been from one of those.

Agree kretzschmaria is probably main pathogen, the black lines (pseudosclerotial plates) and lack of obvious decay evident on sounding is indicative. the wood associated with the tap root will have been "eaten" by another fungi. Salt and the inevitable grass cutter damage won't have helped.

Emerging things can often look quite strange. such as this Pholiota aurivella Wood looks like lime perhaps? I don't like mushrooms either but know a lot of foragers who would be chuffed to find at this nice fresh stage

hi Dean It's an emerging clump of Oyster mushroom, Pleurotus ostreatus Cheers Mike

Why not just call the cops (or LA enforcement team). surely enough evidence there for a prosecution.

It's a fair point, but it looks to me like these are young FBs, where the veil is still intact and the ring has yet to form. Colour could be down to photo, but looks more orange rather than the yellow/brown of Pholiota. Hopefully OP can do spore print and decide for sure

pics aren't good enough to be sure, but having had another look, i'm now thinking it could be Fairy ink Cap, coprinellus disseminatus It looks to me as if it's feeding on a dead column of wood which the tree has been adapting to, for a long time. But, as Derek says, certainly worth checking for further for evidence of decay if there are any targets edit. Liberty caps are a grassland species
