what causes mushrooms to grow in grass

Mushrooms are the reproductive part of fungi that live in the soil. They grow when fungi that have been living underground all along respond to changes in temperature, light, and water. When the conditions are right, the fungi obtain nutrients that allow them to grow and prepare for reproduction. The resulting mushrooms, essentially fungal flowers, can release millions or even billions of microscopic spores into the air, which play a similar role to that of pollen for plants. Ultimately, mushrooms develop from decaying material in the soil such as wood or even grass clippings. They break down organic matter, helping to stimulate microbial activity and give back to the turf. Mushrooms usually emerge out of the ground after heavy rain and when growing conditions are ideal, hot, and humid. They’ll spread their spores, and then go away when the sun comes out and the soil dries up. Mushrooms are not harmful and are an indication of beneficial microbial activity occurring in your soil.
