What You'll Learn
Mushrooms are often toxic and should not be eaten
Mushrooms that pop up in your garden are likely to be toxic, so it is best not to eat them. While they may be beneficial to your garden, providing disease resistance and aiding the decomposition process, they can be harmful to humans and pets if consumed.
Determining which mushrooms are edible and which are not is challenging and potentially deadly if incorrect. Many mushroom varieties look similar, and even a trained eye can struggle to distinguish between safe and unsafe mushrooms. Some toxic mushrooms may even resemble those sold in grocery stores. Furthermore, just because an animal has eaten a mushroom without apparent harm does not mean it is safe for human consumption.
The toxins in mushrooms can cause a wide range of adverse health effects, from slight gastrointestinal discomfort to permanent organ damage and even death. Some mushrooms contain hallucinogens, such as ibotenic acid and muscimol, which can lead to euphoria and altered sensorium. Other manifestations of mushroom toxicity include headaches, vertigo, palpitations, rhabdomyolysis, hemolysis, dermatitis, and cramping. In severe cases, mushroom poisoning can result in hepatic failure, altered mental status, hypoxia, respiratory distress, and seizures.
Even mushrooms that are typically considered edible can sometimes be harmful. For example, Paxillus involutus, a mushroom eaten in Europe after pickling or parboiling, was found to contain a toxin that can stimulate the immune system to attack red blood cells. This reaction is rare but can occur even in individuals with a history of safely consuming the mushroom. Similarly, Tricholoma equestre was once widely regarded as edible until it was linked to rare cases of rhabdomyolysis.
To avoid mushroom poisoning, it is crucial to only consume mushrooms purchased from stores or obtained from mushroom experts. While some mushroom toxins can be neutralized by special preparation methods like cooking, pickling, or drying, many toxic species remain unsafe regardless of how they are prepared. Therefore, it is always better to err on the side of caution and refrain from eating mushrooms from your garden unless you are absolutely certain of their safety.

Mushrooms can benefit gardens by breaking down organic material
Mushrooms are often seen as a sign of a healthy garden. They are part of a larger fungal network that lives in all living soil. This network, called mycelium, breaks down organic material and releases nutrients that plants can use. Mycelium mats can be found on the forest floor, breaking down organic matter and converting it into simpler forms that can be used by plants, herbs, and shrubs.
Mushrooms are a good indicator of healthy soil. They are a sign of an awesome mycelium network in your soil. They benefit crops by providing disease resistance and allowing for the transmission of chemical signals through the soil, all while expediting the decay process of humus. They are also part of the carbon cycle, breaking down dead plant matter and making it usable for living plants.
The presence of mushrooms in a garden can indicate that there is a lot of organic material in the area. This organic material is broken down by the mycelium, which releases nutrients that the plants can use. Mushrooms can also help move nutrients through the soil, ensuring that they are distributed to the plants that need them.
In addition to their direct benefits to plants, mushrooms can also be aesthetically pleasing. Some people enjoy seeing mushrooms sprout in their yards, as it indicates that something is going right in their garden. However, it is important to note that not all mushrooms are beneficial, and some can be toxic. Therefore, it is not advisable to eat mushrooms from your garden unless you are absolutely certain that they are safe.

Mushrooms grow in moist environments
Mushrooms are a common occurrence in gardens, and while they may be unsightly to some, they are generally not harmful. In fact, the presence of mushrooms indicates the presence of mycelium, which is beneficial for your garden. Mycelium breaks down organic material and releases nutrients that your plants can use. It also helps in the decomposition process, converting decaying material into nutrients that your plants can absorb.
However, it is important to note that not all mushrooms are beneficial. Some fungi can act as pathogens, attacking and killing trees and bushes, especially if they are already unhealthy. Therefore, if you notice shelf fungus forming on a tree, it is important to consult an expert to assess the health of the tree.
While mushrooms themselves may not be harmful to your garden, it is crucial to exercise caution when it comes to consuming them. Most mushrooms that pop up in gardens are likely to be toxic, so it is strongly advised not to eat them or allow your pets to consume them. Determining which mushrooms are edible and which are not can be challenging, and consuming the wrong type can have serious consequences.
Mushrooms thrive in moist environments, and their growth is influenced by humidity levels. They grow through cell division and then rapidly increase in size using cell enlargement, absorbing water and "ballooning up." This is why they are often associated with damp and humid conditions. To encourage mushroom growth, cultivators are advised to ensure ready access to water, whether through natural means or artificial methods like humidity tents.
In summary, while mushrooms growing in your garden are generally not a cause for concern and can even indicate healthy soil, it is important to be cautious when it comes to consumption. Leave the identification of edible mushrooms to experts, and always wash and cook your produce thoroughly to avoid any potential risks.

Mushrooms are part of a larger fungal network in the soil
Mushrooms are the reproductive structures of fungi, and what we see above the ground is just a small part of a much larger network of fungal filaments called mycelium. This network is made up of incredibly tiny threads called hyphae, which wrap around and bore into tree roots.
The mycelium plays a crucial role in fungal reproduction. When two compatible fungi meet, their cells fuse together, allowing their DNA to mix and creating new spores. These spores are then transported by wind or animals and grow into new mycelium when they land on the ground. Fungi can also split their mycelium into smaller fragments, which then form independent networks.
Mycelial networks are an essential part of healthy soil, as they break down organic matter, recycling leaf litter and providing food for bacteria and animals that live in the soil. They also help to eradicate pollutants from the environment, including petroleum products and some pesticides, through a process called mycoremediation. Mycelium mats can act as biological filters, removing chemicals and microorganisms from soil and water in a process known as mycofiltration.
In addition to their role in decomposition and soil health, mycelial networks also facilitate communication and the transfer of resources between plants. Mycelium constitutes 20-30% of soil biomass and 83% of plants exhibit a mutualistic association with mycelium, allowing them to share resources and signals. For example, in a greenhouse experiment, tomato plants infected with early blight sent signals to healthy plants, which then produced defensive enzymes to protect themselves from infection. This process is known as mycorrhizal association.
So, while mushrooms themselves may not be harmful or beneficial to your garden, the presence of a large network of mycelium indicates healthy soil and the potential for plant communication and mutual aid.

Mushrooms can be removed by scraping them off and covering with gravel or cinnamon
Mushrooms in your garden can be beneficial as they help break down dead material and return nutrients to the soil. However, they can be a nuisance and a source of concern if you have children or pets, especially if the mushrooms are toxic. If you want to remove mushrooms from your garden, you can try the following methods:
Scraping and covering with gravel
Firstly, simply plucking mushrooms will not kill them as they are often much larger beneath the surface of the soil. To effectively remove mushrooms, you must target the entire fungal network. When you see mushroom caps appear, pull them out of the ground to prevent them from releasing spores, which will lead to more mushrooms. You can also try mowing or raking over the mushrooms, but this may increase the chances of them spreading spores across your lawn. Therefore, it is important to rake and sweep up any debris after power raking your lawn.
To prevent mushrooms from growing in the first place, you can introduce proper drainage in your garden. Mushrooms thrive in damp and humid places, so by improving drainage and reducing shady spots, you can make your lawn less hospitable to mushrooms. This can be achieved by building up soil to redirect excess water, adding a pond or water garden, placing rain barrels beneath waterspouts, or installing an underground drain such as a French drain filled with gravel.
Covering with cinnamon
Cinnamon is a natural fungicide that can be used to prevent and deter mushrooms. To use cinnamon as a preventative measure, create a cinnamon spray by stirring cinnamon into warm water and letting it steep overnight. Strain the liquid and put it into a spray bottle. Spray the potting soil in plants that have a mushroom problem, or mist the stems and leaves of affected plants. You can also sprinkle cinnamon powder directly onto the soil or affected areas of the plant.
By combining these methods of scraping and covering with gravel or cinnamon, you can effectively remove and prevent mushrooms from taking over your garden.
