History and culture

The king trumpet mushroom (Pleurotus eryngii), which is known as the “king oyster mushroom,” is the largest member of the oyster mushroom family. French horn mushroom, trumpet royale, and the more common name “king trumpet” all refer to the trumpet-shaped cap of the mushroom, which grows from a thick stem.

Native to the Mediterranean, North Africa, and the Middle East are king trumpet mushrooms. But they are now grown all over the world because of their recent rise in popularity. Because of their umami flavour, they are particularly well-liked in China and Japan.
