Fairy ring mushrooms are popping up in lawns after a couple of weeks of rain.
In folklore, the mushrooms follow the path of fairies dancing in a ring. So far, we’ve only been able to get photographs of the mushrooms growing in their intriguing circles.
The fungus doesn’t harm the lawn, said LSU AgCenter horticulturist Dan Gill.
“Saprophytic fungi, those that produce mushrooms in our lawns, decay dead organic matter,” Gill said.
The fungus grows in all directions, creating a roughly circular organism beneath the ground.
“As the years go by,” Gill said, “and the organism enlarges, the middle dies out leaving behind a ring-shaped fungal organism” below ground.
“When weather conditions are damp, the fungus sends up mushrooms.” Since the fungus organism under the ground is ring-shaped, the mushrooms grow in a circle.
