Identification
Small white-gray funnel caps on soil in rings; gills whitish, decurrent; stem short. Confused with edible field species — including the St George's mushroom and young meadow mushroom.
Why it is dangerous
A rich source of muscarine: within 15 min – 2 h — sweating, salivation, tearing, abdominal cramps, vomiting, diarrhea; pulse slows, blood pressure falls. Severe courses and deaths are documented in the literature.
In practice
- Small white funnels growing in rings on lawns — skip entirely.
- Muscarinic symptoms after mushrooms → emergency services immediately; atropine is the specific antidote.
