As an avid gardener, I occasionally find brown mushrooms popping up in my yard or garden beds. While some mushrooms are harmless or even beneficial fungi, others can be potentially toxic lookalikes. That’s why identifying and managing brown mushrooms in the garden is so important.
Common Brown Mushroom Species
There are a few types of brown mushrooms that commonly appear in home gardens
-
The haymaker mushroom (Panaeolus foenisecii) is a small brown mushroom with a bell-shaped cap and chocolate-brown gills on a slender stem These mushrooms grow in lawns and mulched beds
-
The common conecap (Conocybe tenera) also has a conical brown cap but is smaller with a fragile stem. It grows in lawns and grassy areas.
-
Brown fairy ring mushrooms (Agaricus arvensis) emerge in circular rings in the grass. They havebrown caps and short, thick stems.
-
The common brown mushroom (Agaricus bisporus) is the typical mushroom you find on pizza. It can pop up in compost piles.
-
Porcini mushrooms (Boletus edulis) have brown caps but are highly sought after for cooking They grow under trees.
Identifying Toxic Lookalikes
It’s critical to correctly identify brown mushrooms in your yard before consuming any wild mushrooms. The deadly galerina marginata is a brown woodland mushroom containing the same toxins as the destroying angel. Conocybe filaris is another toxic brown lawn mushroom.
My tips for identification:
-
Note the mushroom’s features like cap shape, gill color, stem shape, and habitat.
-
Take photos to compare with guides and experts. Consider key details like size, texture, and colors.
-
Never eat any wild mushroom you cannot 100% identify as safe. When in doubt, throw it out!
Managing Mushrooms in the Garden
While most lawn and garden mushrooms are harmless, you may want to control mushrooms for aesthetic reasons or to remove toxic species. Here are some management options:
-
Improve airflow and drainage in the garden to create a less favorable environment for fungi.
-
Apply lime to raise the soil pH above 6.5 to deter mushrooms.
-
Spread cornmeal which contains a fungi-fighting compound called chitinase.
-
Remove mushroom caps as soon as you spot them to prevent spore dispersal.
-
Apply an anti-fungal spray containing ingredients like chlorothalonil, myclobutanil, propiconazole, or trifloxystrobin.
-
For mushrooms growing in your lawn, adjust mowing height, fertilization, and watering practices.
Enjoying Edible Mushrooms
While toxic lookalikes require caution, there are also many edible brown mushroom species to enjoy. Here are some tips:
-
Always purchase mushrooms for eating from a reputable grower or market. Never trust amateur identification for edibility.
-
Wild mushrooms like porcini can be an exotic treat when identified with certainty by an expert.
-
Clean morels, chanterelles and other edible mushrooms thoroughly. Cook before consuming.
-
Try growing your own oyster or shiitake mushrooms if you want homegrown edible fungi.
By correctly identifying brown mushrooms in my garden and using selective control methods, I can safely remove toxic species while allowing beneficial fungal growth. With proper precautions and expert advice, delicious edible mushrooms can also be appreciated. A balanced approach helps make sure mushrooms enrich rather than endanger your garden.
Lawn Mushrooms are a Sign of a Living Soil
More than just a tasty food, mushrooms are a sign that you’re in soil that is full of nutrients and fungi and needs organic matter from trees and shrubs to stay healthy. Fungi are very important for breaking down lignin-based organic materials that are found in tree roots, stumps, leaves, mulch that has broken down, and twigs.
Soils that are full of fungi are very helpful, especially because they can break down tough organic matter like tree leaves, stems, and thatch. With their strong enzymes, fungi can break down wood and even animal bones, which is why they are so important to a healthy ecosystem. You’ll often discover mushrooms flourishing near the decaying organic matter that poses challenges for other decomposers.
Some mushrooms can also be found under the drip line of trees, which shows how important mycorrhizal associations are. Mycorrhiza, which means “fungus roots,” includes helpful fungi that make plants stronger when they’re facing problems like low fertility, drought, extreme temperatures, and root pathogens. Embracing fungi-rich soils not only enriches the environment but also supports plant health and biodiversity.
How to Get Rid of Mushrooms in a Lawn?
Mushrooms tend to appear in lawns primarily when there is decaying wood present. To eliminate mushrooms, you need to remove the decaying woody material from your lawn.
To get rid of mushrooms, you might want to add more leafy things to the soil instead of tree leaves, like grass clippings and vegetable leaves. One effective way to do this is by mulching the grass clippings into the soil. Soils rich in bacteria typically contain more leafy food sources compared to woody ones. On the other hand, soils that are full of fungi tend to have lignin-based food sources, such as tree leaves and decaying wood. Achieving a balanced ratio of bacteria and fungi in the soil can help minimize mushroom growth.
Mushrooms often grow after there has been a lot of rain. This is because the extra water can boost the activity of good microbes and allow the fungi to make a fruiting body, which is the mushroom itself. Importantly, mushrooms won’t hurt your lawn; in fact, their presence is usually a good sign! They mean that the soil is healthy, which is important for growing strong trees and lawns. Most of the time, mushrooms will disappear as quickly as they appear.
Take note if you see mushrooms in your lawn. They are breaking down woody organic matter in the soil, which makes the ecosystem healthier.

What is a brown lawn mushroom?
Mower’s mushroom is a common inedible brown lawn mushroom. Identifying characteristics of the small mushroom are its convex cap that flattens out as it matures, small light brown gills, and a slender stipe. Brown mower’s mushrooms grow 1.12” to 3.14” (3 – 8 cm) tall with a cap 0.4” to 1.12” (1 – 3 cm) across.
How do you know if a mushroom is a lawn mushroom?
The identifying features of common lawn mushrooms are the color, cap shape, length of the stem, the color of gills under the cap, and aroma. Some mushrooms in the yard have a spongy feel, whereas others have gills or pores under the cap. Slicing the mushroom also reveals the color of the flesh.
What are brown wild mushrooms?
The brown wild mushrooms can be identified by their cap shape, type of stem, and where they are growing in a landscape. Brown mushrooms are some of the most common edible mushrooms that people forage for. Common brown mushrooms include morels, portobello mushrooms, porcini mushrooms, king oysters, and shiitakes.
What does a brown mushroom look like?
The brown textured caps can measure 1” to 4.3” (2.5 – 11 cm) tall and the stems up to 4.7” (12 cm). Morel mushrooms are typically dark brown to black. They grow in forests, woodlands, and grassy areas, often near trees such as ash, elm, and apple trees. The delicious brown mushrooms start fruiting in spring and continue through early summer.
Where do brown mushrooms grow?
Brown mushrooms appear in soil under shrubs and near trees when conditions are right. They thrive in soil rich in organic matter when temperatures are warm and humid. Therefore, mushrooms typically appear in yards in late summer and early fall. The brown fungi grow under decaying plant material and decomposing leaves.
Are mushrooms growing in the front or backyard dangerous?
Mushrooms growing in the front or backyard are a common sight. The mushrooms can appear almost instantly in lawns and gardens after a rainy period or in areas with high humidity. Knowing how to identify common yard mushrooms is crucial. Some mushrooms growing in the yard are harmless, whereas others can be toxic and harmful if ingested.
