Clitocybe rivulosa
The fool's funnel is a small, white, funnel-shaped poisonous mushroom of lawns. It contains potentially deadly levels of muscarine, quickly causing heavy salivation, sweating and tears. It is confused with fairy ring champignon and, growing in grass, poses a risk to young children.
Lawns, meadows and other grassy places in summer and autumn, often forming fairy rings.
Widespread in Europe and North America.

It is also called the sweating mushroom because of the symptoms it causes.
Contains muscarine. Within 15-30 minutes it causes heavy salivation, sweating and tears; severe cases add abdominal pain, diarrhoea, blurred vision and laboured breathing. Death from respiratory failure is rare but possible. It grows in lawns where children play and is confused with fairy ring champignon.

Never eat a wild mushroom without showing it to an expert
