Mushrooms in your yard are a common occurrence and are usually harmless. However, some mushrooms can contain dangerous toxins that can cause severe illness or even death if ingested. While it is rare for poisonous mushrooms to grow in residential areas, it is crucial to be able to distinguish between poisonous and edible mushrooms. Some common poisonous varieties include the green-spored parasol or lepiota (Chlorophyllum molybdites) and the death angel or destroying angel (Amanita bisporigera). On the other hand, mushrooms like the ringless honey mushroom are generally considered safe to eat, but even these can be confused with toxic varieties. Therefore, it is always best to consult a mushroom expert before consuming any wild mushrooms.

What You'll Learn
Most yard mushrooms are harmless
Most mushrooms that grow in yards are harmless, and there's no need to panic when you spot them. They are common, easy to manage, and generally not harmful to humans or pets. While it is true that some mushrooms are toxic and can cause severe illness or even death if ingested, it is rare for poisonous mushrooms to grow in residential yards.
Mushrooms are the reproductive structures of fungi, and both bacteria and fungi are essential components of healthy soil. The presence of mushrooms indicates that the soil is in good condition, with millions or even billions of beneficial microbes, including bacteria, fungi, protozoa, nematodes, and earthworms. They are a sign of natural decomposition, thriving in moist, shaded areas where organic matter is breaking down.
While some mushrooms are parasitic, many are decomposers that help cycle organic material back into the soil, or mutualists that help plants access the nutrients they need. For example, stinkhorns, which may pop up in yards after rain, are not considered poisonous and help decompose organic matter. Boletes, which can be identified by their round, fleshy shape and pores instead of gills, are also generally safe and beneficial.
It is important to note that while mushrooms themselves are not harmful to touch, consuming unidentified wild mushrooms can be dangerous. It is crucial to never consume wild mushrooms unless they have been positively identified by an expert. Common poisonous varieties, such as those in the Amanita genus, can be fatal. If you are concerned about the presence of mushrooms in your yard, you can remove and dispose of them to keep your family and pets safe.

Some mushrooms are toxic
While most mushrooms are harmless, some are toxic and can cause severe illness or even death if ingested. It is crucial to never consume wild mushrooms unless they have been positively identified by an expert. Common poisonous varieties, such as those in the Amanita genus, can be fatal. For instance, the death angel or destroying angel (Amanita bisporigera) is a poisonous variety found in lawns. Another example is the green-spored parasol or lepiota (Chlorophyllum molybdites), which can cause severe gastrointestinal distress, including colicky abdominal pain, nausea, vomiting, and diarrhea.
Even non-toxic mushrooms can be harmful to ingest, and some may indicate a plant parasite. While a tree can live with a parasitic fungus for decades, it may be advisable to call an arborist to inspect for signs of deterioration. For example, the ringless honey mushroom (Armillaria tabescens) is often considered edible, but some have reported gastrointestinal distress after consuming them. Therefore, it is important to approach wild mushrooms with caution and only consume them in small quantities initially to test for any adverse reactions.
Some mushrooms are easy to confuse with their poisonous counterparts. For instance, the ringless honey mushroom can be mistaken for the poisonous jack-o'-lantern mushroom (Omphalotus olearius). The false parasol (Chlorophyllum molybdites) is another example of a toxic mushroom that resembles its non-toxic counterparts. Therefore, it is essential to seek expert identification before consuming any wild mushrooms.
While most lawn fungi are harmless, it is always better to be safe than sorry when it comes to potential toxins. If you are unsure about the identity of a mushroom in your yard, it is best to avoid contact and seek professional advice. Additionally, if you, your family, or your pets exhibit any unusual symptoms after coming into contact with an unidentified mushroom, it is crucial to contact a doctor or veterinarian immediately.

Mushrooms indicate healthy soil
Mushrooms in your yard can be alarming, but they are usually harmless. While some are toxic and harmful to ingest, most are harmless and some are even beneficial. They are a sign of fungal-active soil, which is good for trees, shrubs, and other plants. Fungi break down organic matter into nutrients that plants can use, helping plants to access the nutrients they need. They also break down complex organic compounds of proteins, carbohydrates, and fats into their most basic elements, which can be used by other organisms.
Fungi and bacteria play an integral role in the earth. Plants rely on soil fungi and bacteria to digest nutrients for them and, in return, feed soil organisms with sugars produced through photosynthesis. Underground, below the mushrooms, are thread-like networks called hyphae. Some attach to plant roots, increasing the surface area of the roots up to a thousand times. This helps plants access water and nutrients and even helps plants communicate with each other.
A healthy fungi population is essential for healthy soil. Most mushrooms are harmless, but some can be harmful or even deadly if eaten. If you are concerned about the presence of mushrooms in your yard, it is best to consult a specialist or expert.
While mushrooms can be beneficial, it is important to exercise caution, especially if you have children or pets. Some mushrooms are toxic and can cause stomach aches or other adverse effects if ingested. It is always best to leave mushrooms alone and not consume them unless you are certain they are safe to eat.
Overall, while it is understandable to be cautious of mushrooms in your yard, they are often a sign of healthy soil and can be beneficial to your plants.

How to remove mushrooms from your yard
Mushrooms in your yard can be unsightly, but they are usually harmless. However, if you want to get rid of them, there are several methods you can try.
First, it is important to understand that mushrooms thrive in dark and humid environments with poor drainage and a lack of sunlight. Therefore, one way to prevent mushroom growth is to make the soil conditions less favourable for them. You can do this by raking your lawn to dry it out faster, cutting tree branches to allow more sunlight, and keeping the grass cut short. Additionally, avoid overwatering your garden, and consider installing a French drain to help water drain faster from your yard.
Another way to remove mushrooms is to physically remove them by hand. When doing this, it is important to wear gloves and place the mushrooms in a plastic bag to prevent the spores from becoming airborne. You can also cut off their protective caps with a knife or mow over them with a lawnmower, leaving them to dry out and die in the sun.
You can also try spraying the mushrooms with a mixture of water and a mild fungicide, such as dish soap or vinegar. For vinegar, dilute four parts water to one part vinegar, and be careful where you spray it, as it can kill anything else it comes in contact with. Alternatively, you can mix one tablespoon of baking soda with one gallon of water and spray it over mulch to kill any mushrooms growing there.
If the mushrooms in your yard are parasitic, removing them alone may not solve the problem. In this case, consider calling an arborist to inspect your trees for signs of deterioration. Additionally, if you are unsure about the safety of the mushrooms, contact your local lawn care specialist for help.

How to identify edible mushrooms
Mushrooms in your yard are generally harmless, but it's important to identify them correctly before consuming them. While most lawn mushrooms are non-toxic, some can cause stomach aches or more severe symptoms. Poisonous mushrooms rarely grow in residential yards, but they can be dangerous if consumed. Therefore, it is crucial to identify mushrooms accurately before handling or ingesting them.
- Consult a Mushroom Field Guide: Purchase a comprehensive field guide specific to your region. These guides provide detailed information about various mushroom species, including edible and poisonous varieties. The guides typically include illustrations or photographs that can aid in identification. Some guides also offer tips on foraging and preparing wild mushrooms.
- Observe Appearance and Characteristics: Examine the physical characteristics of the mushrooms in your area. Edible mushrooms typically have brown or tan gills, while those with white gills are often deadly. Choose mushrooms with tan, brown, or white caps and stems, avoiding those with red hues. Edible varieties usually lack scales on the cap or a ring around the stem. Remember that no single trait confirms edibility, so observe multiple features.
- Seek Expert Knowledge: Connect with local mycological groups or universities to access expert knowledge. Mycologists (fungi scientists) can provide accurate identification and advice. Consider auditing mycology classes to develop your mushroom identification skills and learn more about edible species.
- Understand Habitat and Behaviour: Learn about the typical behaviour and habitat of edible mushrooms. Certain species may prefer specific environments, such as trees, logs, forest floors, or mossy areas. Understanding their natural habitat can help you make more accurate identifications.
- Be Cautious: Always exercise caution when handling and consuming mushrooms. Do not eat a mushroom unless you are 100% certain of its edibility. If you ingest an unidentified mushroom, closely monitor yourself for any troublesome symptoms, such as gastrointestinal upset, and seek immediate medical care if needed.
- Separate Identified and Unidentified Mushrooms: When foraging, carry two baskets. Place the mushrooms you are confident are edible in one basket and those you are uncertain about in another. This practice helps ensure that you don't accidentally consume unidentified mushrooms.
Remember, mushroom identification requires knowledge and expertise. While these guidelines provide a starting point, it is always best to consult experts or seek professional advice when in doubt.
