Very grey cap, dark grey centre and scales on pale cap. Strong PINK ring left on stipe. Strong smell - ammonia(?) but may be due to age.
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.
Looks like a Lepiota or that grouping, bulbous base to stipe & a heavy persistent ring would indicate such;the exposed gills at the margins too.
