The Greener Guide to Mushrooms in the Yard and What to Do About Them

Mushrooms. They pop up overnight. They gather in fairy rings, huddle in shady corners, or boldly erupt from the middle of your lawn. And they spark just as many questions as they do curiosity: What are these mushrooms doing here? Are they dangerous? Can I get rid of them? Are any of them edible? (And should I even try?)

At Be Green Pro, we field a lot of mushroom-related questions, especially in the spring and fall when conditions are just right for fungi to flourish. Here’s everything you need to know to feel confident when mushrooms show up in your lawn.

‍

Mushrooms are the fruiting bodies of fungi that live beneath the soil. Their presence is usually a sign of organic material decomposing in your lawn—things like buried wood, dead tree roots, mulch, or even thatch.

In many cases, they’re not a problem at all. In fact, mushrooms are often a sign that your soil has good biological activity. But too much of a good thing (like excess moisture or poor airflow) can lead to a mushroom takeover.

Common causes include:

• Decomposing Wood or Roots: That old tree you had removed years ago? Its roots are likely still breaking down underground—the perfect buffet for mushrooms.
• Mulch or Thatch: Heavily mulched areas or lawns with thick thatch layers can also harbor fungi.
• Poor Drainage or Compacted Soil: These create pockets of moisture fungi love.
• A Good Sign? Yes! Mushrooms mean your soil is full of organic matter and microbial life. It’s a sign of a healthy, biodiverse yard.

‍

Most mushrooms you see in the lawn are harmless, especially if you're not eating them. However, it’s smart to play it safe:

• Don’t let kids or pets chew on them. Some species are toxic, even deadly if ingested, and identification can be tricky. Always supervise pets and children if mushrooms are present.
• Puffballs are generally harmless when small, but when they burst open with spores, they can create respiratory irritation if you mow through large amounts, especially if you have mold allergies or respiratory issues, we recommend gently raking mushrooms into a compost bag instead.
• Mower spores? Yep, if you mow over mushrooms, especially puffballs, you may inhale spores. It’s not usually a health threat, but it’s one more reason to knock them down first with a rake.

‍

While most mushrooms are natural decomposers, some fungi are signs of turf disease:

• Fairy Rings (circular patterns of mushrooms): often indicate fungal growth and compacted soil.
• Mushrooms that coincide with yellow or dying patches of grass may point to underlying lawn disease.
• Fungus mats or musty smells: Call us. This could mean your lawn has a turf disease or decay issue that needs treatment.

Be Green Pro offers low-toxicity and organic treatment options for fungal diseases that help your lawn recover without harming the environment.

‍

You can’t completely prevent mushrooms—and that’s okay. But if they bother you or keep coming back, you have a few options:

• Rake Them Out: The simplest way to manage mushrooms is to rake them up and toss them in your compost or yard waste bin.
• Improve Drainage: Aerating your lawn helps reduce compaction and encourages faster drying after rain.
• Treat the Soil: Be Green Pro offers microbial aeration and soil amendment services that balance your lawn's biology, reducing conditions that lead to fungal outbreaks.
• Remove Decaying Wood: If mushrooms are growing in a consistent spot, there may be buried wood or mulch underneath.
• Ignore them. In many cases, they disappear on their own when the lawn dries or is mowed.
• Fix the conditions. Improve airflow, reduce watering, and consider microbial aeration to reduce soil compaction.
• Call Be Green Pro if mushrooms are persistent or connected to larger turf problems.

‍

Can Mushrooms Be Treated?

Yes. For lawns with persistent mushroom issues due to turf disease or excess moisture, we can apply targeted fungicide treatments or develop a tailored soil health plan. However, it’s important to treat the cause—not just the symptoms.

‍

Are Mushrooms Edible?

Here’s where things get fun and risky. Some wild mushrooms, like morels or puffballs, are edible when harvested fresh and correctly identified. But misidentifying mushrooms can be dangerous or even deadly.

Our tip: Never eat a mushroom unless you are 100% certain of its identity.

‍

The Curious Case of Morels

Morel mushrooms are a prized wild edible that show up in spring in wooded or shaded areas. They are NOT likely to be found in well-kept suburban lawns, but people often get excited when they think they spot one.

Morels have a distinct honeycomb texture, but beware of false morels, which can be toxic. If you're lucky enough to forage real ones, congrats! (And yes, they are delicious sauteed in butter or olive oil with a pinch of salt.)

‍

What Are Those White Balls? (And Can I Eat Them?)

If you see small, white balls that resemble mini marshmallows, you might have puffball mushrooms. Some puffballs are edible when very young and firm (they should be solid white inside with no gills or dark spots), but others are easily confused with toxic lookalikes.

Puffball Test Tip: Cut one in half. If it's pure white and has a texture like a marshmallow or mozzarella ball, it might be safe. If you see anything else—discard it. When in doubt, leave it be or consult a local expert.

‍

If you’re 100% sure you’ve got edible puffballs, try this simple Wisconsin-style recipe:

Puffball Parmesan Bites

• 1 large puffball mushroom, sliced into ½” rounds
• 2 eggs, beaten
• ½ cup breadcrumbs
• ½ cup grated parmesan
• Salt, pepper, and herbs to taste
• Olive oil for frying

Instructions:

1. Heat oil in a skillet over medium heat.
2. Dip each puffball slice into egg, then coat in breadcrumb/parmesan mix.
3. Fry until golden on both sides.
4. Serve with marinara or ranch for dipping.

Note: Always consult a mushroom expert or forager before consuming wild mushrooms.

Simple Sauteed Puffball Slices

Small puffballs (smaller than a baseball) are edible if they are solid white inside with no gills. Slice, saute in garlic butter with a dash of salt and thyme, and serve over toast or pasta. Always verify ID before consuming any wild mushroom.

Preventing Mushrooms (Without Harsh Chemicals)

• Improve drainage
• Mow regularly
• Reduce shade or improve airflow
• Use microbial aeration to break up compacted soil
• Add organic-based soil amendments to improve the microbial balance
