This was approx 1cm in diameter and found in the undergrowth within a Birch wooded area. Cheers.
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.
While I agree with David's ID, this specimen does seem very small for a parasol.
It is not a parasol,it is a Lepiota but as Flaxton's say's you need microscopic detail to narrow it down to which one.
