उत्तर
After heavy rains in the forest, moisture and nutrients pass down in the soil and activate the growth of mushroom mycelium. The basidiocarps of Agaricus (mushroom) arise from the mycelium present in the ground. They appear in a circle like a ring. As these basidiocarps resemble buttons and grow in rings, they are known as fairy rings.
