Large fungus - comare rucksack which is approx 32cm at its widest
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Did you notice if it had gills or pores on the underside?
any chance of a higher resolution image or more zoomed in version. as a first guess I'd say dryad's saddle but would like to see more detail.
Sorry - missed these comments. Agreed another pic would help. Dryad's saddle more often grows on Beech but I don't think its that fussy
In my experience Dryads saddle very often grows on ash but also several other species.
It does appear to have a lot of the same characteristics as Dryads saddle. its flowering a little late, usually seen in the spring. but that could just be down to the warmer weather.
Thanks for all of your suggests - hi-res picture now added.
