Possible lookalikes Could be confused with the Mousseron (Marasmius oreades), which alsogrow in rings in grassland. However, the gills of the Mousseron are adenexed or free of the stem, while the gills of the Fool's Funnel are decurrent (run down the stem). The Fool's funnel  also lacks an umbo.

Looks very similar to The Ivory Funnel (Clitocybe dealbata), which is also deadly poisonous and thought to possibly be the same species
