After heavy rainfall, unwanted mushrooms pop up everywhere
Question: After rainy periods, we get mushrooms in different spots in the yard. Some are white, some black. Some are in groups, and some are singles. Some are in the sun; others are in the shade. What gives?
Answer: A mushroom is a sort of “flower” for a fungus. It is the life-cycle stage where the spores are released to create more fungi. It is also the sign of a healthy fungus.
In the landscape, fungi usually produce mushrooms when the air and ground are moist. That’s because high humidity and wet surfaces are necessary for the spores to germinate and grow. Even in regions that are suffering from drought, many people over-water their landscapes, so they get mushrooms, too.
Fungi in the landscape are mostly beneficial. They break down dead material into basic chemicals that are then used by other organisms, especially plants. The fungi in your lawn are helping to decay organic matter into nutrients that are beneficial to your lawn grass.
Often, the fungi in a lawn started at a place where a dead tree was located, or where another concentration of organic material, such as building materials, was buried under the grass.
Usually, the fungus spreads out in all directions from that location. That is why you see lawn mushrooms in circles. When a couple of circles meet, you might get a figure “8” or some other shape.
If you want to remove the mushrooms, go ahead. They are not harming the lawn, but they can be unsightly.
