What happens if someone eats Green-spored parasol?

Did someone eat a wild mushroom and feel sick? Call emergency services and bring a sample of the mushroom.

Toxins
Researchers have isolated molybdophyllysin, a toxic protein belonging to the zinc metalloproteases. Its toxicity was studied in mice; that experiment must be distinguished from clinical evidence in people.
When symptoms start
The first symptoms usually appear within 1–3 hours after eating it.
What to do
If you ate it or suspect someone ate it, call a poison center or emergency services right away. Do not wait for symptoms. Keep a mushroom sample and take it with you to help identification; also save photographs if you have them.
