Fairy Rings: Mushroom Circles, Science, and Magic | Smartest Year Ever (Mar 5, 2025)
About this episode
Mushrooms in perfect circles? Folklore calls them fairy rings—portals to the supernatural where sprites dance and witches gather. But the real magic is fungal biology. These eerie centuries-old formations grow as a fungus expands outward, creating rings that get bigger every year. Some kill grass, others make it greener, and some even produce plant hormones!
Today, Gordy digs into:
The science behind fairy rings—how fungi spread in a perfect circle
Ancient myths that warned of curses and time loops
A massive 2,000-foot-wide fairy ring in France
Why some fairy rings kill grass while others make it flourish
