Fool's Funnel Mushroom Overview

Clitocybe rivulosa is commonly known as Fool's Funnel Mushroom. It is a poisonous, funnel-shaped basidiomycete fungus belonging to the large genus, Clitocybe. It's a pure white mushroom, the diameter of the caps can reach around 3-4cm. This fungus has no particular taste or smell. It tends to grow in a fairy ring so is often mistaken for the edible Fairy Ring Champignon (Marasmius oreades). To make things more confusing, both mushrooms tend to grow close to one another, frequently tricking foragers. Fool's funnel contains muscarine, a poison which works by targeting cell receptors involved in the nervous system. It's also referred to as the 'sweating mushroom' because the main symptom includes increased salivation and sweating. Larger doses can result in abdominal pain, severe nausea and diarrhoea, blurred vision and difficulty with breathing.
