Mushrooms are commercially cultivated over the world and safe for human consumption, except in those with known allergies. Among the thousands of mushroom species identified, few are considered to be edible. Mushroom hunting has emerged as an adventure and recreational activity in recent decades. Wild forms of mushrooms are often poisonous and visually mimic the edible ones, thus leading to mistaken harvesting, consumption, and toxicities. In literature, various systemic toxic syndromes associated with mushroom poisoning have been described. We report four members of a family with muscarinic manifestations after accidental consumption of poisonous mushrooms. The Clitocybe species of mushrooms they consumed resulted in their muscarinic toxicity. Patients with muscarinic mushroom toxicity have early onset of symptoms and they respond well to atropine and symptomatic supportive care.
