Cap up to 15cm
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.
It could be but there are signs of yellow towards the cap edge so it could also be Agaricus xanthoderma. Did it have any aroma and did it have any yellow at the base of the stem?
Sorry but I can't remember what the smell was.
