On the way back up the trail we stumbled upon this cute
little patch of mushrooms.
Coming up next...Dale Hollow lake!
In grass, the best known fairy ring fungus has the scientific name
Marasmius oreades. The body of this fungus, its mycelium, is
underground.
It grows outward in a circle. As it grows, the mycelium uses up all of the nutrients in the soil, starving the grass. This is the reason a fairy ring has dead grass over the growing edge of the mycelium. Umbrella-shaped fruiting bodies, called mushrooms, spring up from just behind the outer edge of the mycelium. Large rings are created when the older mycelium in the center finally exhausts the soil nutrients and dies. On the death of the central mycelium, the nutrients are returned to the soil and grass can grow again.
