Hericium americanum, commonly known as the American lion's mane mushroom, is a type of edible fungus found in North America. It typically grows on decaying hardwood trees, particularly oak and maple. This mushroom is characterized by its white, fluffy appearance, resembling a lion's mane, and can grow quite large, sometimes reaching up to 12 inches in diameter. This species is not only valued for its culinary uses but also for its potential health benefits. Research suggests that Hericium americanum may support cognitive function and nerve health due to its bioactive compounds. It is often used in traditional medicine and dietary supplements.
