What are fairy rings?

Fairy rings are mushrooms that appear in a circular formation, usually in forests or grassy areas.

They have been associated with the presence of fairies or elves and are thought to be good or bad luck, depending on the tradition.

When a mushroom spore lands in a suitable location, the underground hyphae (fungus roots) grow out evenly in all directions.

As the fungus grows and ages, the oldest parts in the center of the mat die, creating a circle.

When the fungus produces its mushrooms – the fruiting bodies – they appear aboveground in a ring.

Given that the fungus does not die when the mushrooms fade, a fairy ring can persist for many years and continually increases in size.

One enormous fairy ring in France is thought to be more than 700 years old!
