Representative mushrooms causing poisoning cases Rhodophyllus rhodopolius Figure

This mushroom shows the highest incidence of poisoning in Japan, because a very similar edible species Rhodophyllus crassipes is available and grows at similar locations. The poisoning symptoms are vomiting, diarrhea and abdominal pain appearing 30 min-3 h after ingestion. The stem of Rhodophyllus rhodopolius is easily crushed by pressure with the finger, but that of the edible Rhodophyllus crassipes is not. The toxic compound being contained in the mushroom is reported to be muscarine or choline.
