Why Is There Mushrooms Growing In My Yard?

Mushrooms, as you no doubt know, belong to the fungus kingdom and come in many different shapes and sizes. In nature, mushrooms thrive in humid, dark, and nutrient-rich places. However, you must not confuse lawn mushrooms with edible varieties, as doing so can be lethal or highly unpleasant.

Various types of organic debris, such as animal feces, rotting grass, brittle leaves, tree trunks, and even underground tree roots, can all be found in a yard. Mushrooms can convert these plant wastes into plant-usable nutrients from decaying material.

How Do Mushrooms Reproduce and Spread

Spores are the means through which mushrooms propagate. To reproduce, all the mushrooms send spores into the air, like tiny reproductive cells. They set down, and a new mushroom civilization is born. Mushrooms create wind to help the spreading of spores.

When mushrooms release moisture, they condense into water vapor and provide a relaxed environment. This provides the propulsion for the spores to multiply and spread. The natural wind of this fungal growth can carry the spores as high as two to four inches.

Spores hibernate through drought or other environmental stresses to wait for favorable conditions before germinating and producing new mushrooms.
