Mushrooms growing in houseplants can be startling, but they are generally harmless to the plant. They are saprophytic fungi, which means they feed on decaying matter in the soil and convert it into food for the plant to absorb. However, certain types of mushrooms, such as the bright yellow Leucocoprinus birnbaumii, are toxic to humans and pets, so it is important to remove them if children or animals are around. These mushrooms may be an indicator of overwatering, so it is recommended to allow the soil to dry out a little before watering again.

What You'll Learn
Mushrooms in houseplants are usually harmless to the plant
However, the presence of mushrooms in houseplants may indicate that the plant is being overwatered. Mushrooms grow when there is consistent moisture and organic material in the soil. If the potting soil is moist enough for mushrooms to grow, it is probably too wet. Houseplants, especially succulents, prefer to dry out a little before being watered again.
While mushrooms themselves are usually harmless to the plant, certain types of mushrooms are toxic to humans and pets. The most common type of mushroom found in houseplants is Leucocoprinus birnbaumii, also known as the yellow parasol or yellow houseplant mushroom. These mushrooms are toxic to people and animals and should be removed immediately if there are children or pets in the home.
If you do not like the appearance of mushrooms in your houseplants, it is safe to remove and dispose of them. However, it is important to note that fungicide treatments are unnecessary and may harm the plant by adding harmful chemicals to the soil.

They can be beneficial to the plant
Mushrooms appearing in houseplants can be beneficial to the plant for several reasons. Firstly, they indicate that the soil is healthy and contains a diverse range of microorganisms, including bacteria and fungi, which contribute to a thriving ecosystem. This ecosystem, when balanced, can boost the immunity of the plants and protect them from pests.
Secondly, mushrooms themselves are saprophytic fungi that feed on decaying organic matter in the soil, such as compost, expired roots, leaves, or dead insects. By breaking down this organic matter, they release nutrients that the plant can then absorb and utilize for growth and development. This symbiotic relationship between the mushrooms and the plant is beneficial to the plant's health and nutrient uptake.
Additionally, the presence of mushrooms can be a sign of consistent moisture and organic material in the soil, which is essential for the plant's growth. However, it is important to monitor the moisture levels as excessive watering can lead to overwatering, which may not be favourable for the plant.
While mushrooms can be beneficial to the plant, it is important to consider the type of mushroom and the presence of pets or children. Some mushrooms, such as the Leucocoprinus birnbaumii, commonly known as the yellow houseplant mushroom, are toxic to humans and animals if ingested. Therefore, it is recommended to remove and dispose of the mushrooms if there is a risk of consumption by children or pets.

They can be toxic to humans and pets
Mushrooms in houseplants are not usually harmful to the plants themselves. However, they may pose risks to humans and pets if consumed, especially in the case of allergies. The Leucocoprinus birnbaumii (Flowerpot Parasol) species, for instance, is toxic to both humans and pets if ingested. The Conocybe species of mushrooms, which have a conical cap and are often brown, are usually not harmful to plants, but some species can be toxic if eaten.
If there are pets or young children in your home, it is recommended to remove the mushrooms and the plant from their reach. This is because mushrooms can be toxic if ingested, and the spores, which spread easily, can be hard to spot unless they have formed large colonies. While fungicide treatments are ineffective, you can prevent mushrooms from growing by ensuring your plant is not overwatered, as mushrooms thrive in moist environments. Check the soil before watering, and ensure proper drainage to prevent root rot.
If you notice a large number of mushrooms growing, it may be a good idea to remove them to reduce competition for nutrients with your plant. When removing mushrooms, gently pluck them out without disturbing the roots of your plant, and be sure to wear gloves as a precaution.
While mushrooms can be toxic to humans and pets, they can also be beneficial to the soil's health by breaking down organic matter and releasing nutrients for the plant to use. However, their presence may also indicate that something is not right with your care routine, and if left untreated, the fungus can take over and cause your plant to die.

They are caused by moisture and organic material in the soil
Mushrooms in houseplants are typically caused by moisture and organic material in the soil. The presence of mushrooms indicates that the soil is too wet, and they are most likely to appear in consistently moist environments with organic material, such as potting mix.
The mushrooms themselves are the reproductive structure of fungi, which spend most of their life cycle underground in the soil as thread-like bodies, or mycelium. When the environmental conditions are favourable, the fruiting body, or mushroom, emerges. While the mushrooms themselves are not harmful to the plant, their presence may indicate overwatering.
The mushrooms that grow in houseplants are often saprophytic fungi, which feed on decaying matter in the soil, such as compost, expired roots, leaves, or dead insects. These fungi can benefit the plant by breaking down organic matter and releasing nutrients that the plant can absorb. However, if left unchecked, overwatering can lead to an excess of fungi, which can compete with the plant for nutrients and water.
It is important to note that some mushrooms, such as the Leucocoprinus birnbaumii, commonly known as the yellow houseplant mushroom, are toxic to people and pets. If there is a risk of ingestion, it is recommended to remove and dispose of the mushrooms immediately. Additionally, ensuring that the plant dries out between waterings can help prevent the recurrence of mushrooms.

They can be removed and disposed of
Mushrooms in houseplants are typically not harmful to the plants themselves. In fact, they can be beneficial, as the fungus breaks down organic matter in the soil, releasing nutrients that the plant can use. However, if you have pets or children who might try to eat the mushrooms, it is best to remove and dispose of them, as some varieties are toxic when ingested.
If you notice mushrooms growing in your houseplants, it is important to identify the type of mushroom to determine whether it is toxic. The most common type of mushroom found in houseplant soil is Leucocoprinus birnbaumii, also known as the yellow houseplant mushroom or flowerpot parasol. This variety is toxic to humans and animals and should be removed immediately if you have pets or children in your home. Other common toxic mushrooms include Amanita phalloides, Galerina marginata, and Conocybe filaris. While the exact level of toxicity of L. birnbaumii is unknown, it is believed to cause mild gastrointestinal distress in humans and animals.
When removing toxic mushrooms from your houseplants, it is important to wear gloves or use paper to protect your hands. Scoop out the mushrooms and dispose of them in the trash rather than the compost bin to prevent them from growing in your garden. It is also a good idea to keep the plant out of reach of children and pets.
To prevent mushrooms from growing in your houseplants, ensure that you are not overwatering your plants. Mushrooms thrive in moist environments, so allowing the potting soil to dry out a little between waterings can help deter their growth. Additionally, you can use botanical extracts and plant care tonics to encourage a healthy soil ecosystem, which can help to deter pests and create an environment where mushrooms are less likely to thrive.
