Mushrooms Popping up in Your Lawn?

Today’s post is from Brian Eshenaur, Senior Extension Associate for Ornamental Crops Integrated Pest Management Program, working out of Monroe County.

As fall approaches with its chilly air and increased soil moisture, fungi often respond by producing mushrooms.  Think of mushroom structures as the “flower” of the fungi. The gills under the umbrella cap produce tiny spores.  Like seeds, they disperse on the breeze or foot traffic and may grow under suitable conditions.

The mushrooms we see indicate an extensive network of fungal hyphae below ground.  They are not feeding on the lawn, rather it’s dead organic matter on which they decay and digest, and most often start on dead roots or stumps.

What should a homeowner do?

First, realize that they are not harming the lawn and will fade back into the ground in a matter of days. Enjoy the temporary display!  However, if curious young children or pets will be around the mushrooms, it’s best to step on them to reduce their visibility and any temptation to take a nibble. Most mushrooms are harmless but, until you’re an expert at recognizing the poisonous ones, err on the side of caution.
