A. citrina is common here. Not seen this very white variant before.
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 might be what you suggest but would be better to see more of the features such as the volva and gills etc.
I can look for it again, hopefully it won't have been kicked over yet.
This was pointed out on a foray with local experts.
