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.
Well done on your very first day Simon.
You should always add a few notes to help us identify - like size, surroundings and some structural detail.
It is from the parasola group, though hard to identify which one exactly, I agree with dejayM, and you can never have enough photos of the fungi to assist with an positive id. Happy hunting when the wet weather returns.
I agree it is a Parasola. I wouldn't be certain it is P. plicatilis without spore examination.
