Yellow mushrooms, scientifically known as Leucocoprinus birnbaumii, are a common sight in potted plants and gardens. They are often referred to as the yellow houseplant mushroom, flower pot parasol, or plantpot dapperling. While these mushrooms indicate healthy soil, they can be toxic if ingested, potentially causing gastroenteritis-like symptoms. They thrive in warm, humid environments and can grow rapidly, but they are not winter-hardy and will decay quickly.

What You'll Learn
Yellow mushrooms are a sign of healthy soil
Yellow mushrooms, scientifically known as Leucocoprinus birnbaumii, are a common sight in potted plants and gardens. They are often referred to as the "little yellow houseplant mushroom," "flowerpot parasol," or "yellow parasol." These mushrooms indicate a healthy soil ecology, as the mycelium in the soil helps provide nutrients to the plants.
While these mushrooms are not harmful to your plants, they are toxic to humans and pets if ingested. The toxicity of Leucocoprinus birnbaumii has been classified as having "medium severity poison characteristics" by North Carolina State University. If consumed, it can cause gastroenteritis-like symptoms and may lead to an upset stomach. Therefore, it is essential to keep them out of the reach of children and pets to avoid accidental ingestion.
The appearance of yellow mushrooms can be attributed to the presence of nutritious soil. They thrive in wet soil and hot weather, feeding on dead organic material. Their growth can be quite rapid, and they can reach their full size within 1-3 days. However, they are not long-lasting and will decay soon after.
If you wish to remove these mushrooms from your potted plants or gardens, you can alter the conditions by reducing humidity or lowering the temperature. You can also treat the plant's substrate with a fungicide. However, creating conditions favourable for your plants and less favourable for the mushrooms is often sufficient to prevent their growth.
In conclusion, yellow mushrooms are a sign of healthy soil and indicate the presence of nutritious, organic matter. While they are not harmful to your plants, it is important to take precautions to prevent ingestion by children or pets due to their toxic nature.

They are toxic if ingested and can cause gastroenteritis-like symptoms
Yellow mushrooms, or Leucocoprinus birnbaumii, are toxic if ingested and can cause gastroenteritis-like symptoms. They are commonly known as the flower pot parasol, yellow parasol, flowerpot parasol, or plantpot dapperling. They are a species of gilled mushroom in the family Agaricaceae and are common in the tropics and subtropics. In temperate regions, they frequently occur in greenhouses and flowerpots.
The original classification of this species dates back to the late 1700s in a greenhouse in England, and it was observed in Prague in the early 1800s, demonstrating its long presence in Europe. Despite being a tropical species, it is unlikely to survive in the wild in these countries due to the cold temperatures. However, it continues to spread through human activity, particularly in greenhouses and indoor plant pots, where it finds suitable conditions to thrive.
Leucocoprinus birnbaumii typically grows in plant pots and gardens, and its appearance can be a surprising neon yellow splash of colour. They usually grow to a height of 3-8 cm, with caps that start as bell-shaped and open up to oval or parasol shapes. The cap surface is smooth but dotted with fine scales, and the colour fades from bright yellow to pale yellow and then brown as the mushroom ages.
While Leucocoprinus birnbaumii is toxic if ingested, it is not harmful to your plants. In fact, its presence indicates good soil nutrition. However, if you have children or pets who might try to eat them, it is essential to take precautions. You can treat your plant's substrate with a fungicide or create conditions less favourable for the mushrooms by reducing humidity and temperature. Alternatively, simply place your houseplants out of reach.

They are also known as the 'yellow houseplant mushroom' or yellow parasol
The yellow mushroom, Leucocoprinus birnbaumii, is commonly known as the yellow houseplant mushroom or yellow parasol. It is a species of gilled mushroom in the family Agaricaceae. It is common in the tropics and subtropics and frequently occurs in greenhouses and flowerpots. The caps of these mushrooms are typically between 3 and 8 cm tall and start off bell-shaped, later opening up to an oval or umbrella shape, and finally expanding to the classic, nearly flat parasol shape. The cap surface is smooth but dotted with fine scales, and the colour fades from bright yellow to pale yellow and then brown as the mushroom ages. The stalk is a few inches tall and usually has a ring around it, which disappears with age.
The yellow houseplant mushroom is toxic if ingested and can cause gastroenteritis-like symptoms. However, it is not harmful to plants, so it can be left alone if it is out of reach of children and pets. The mushrooms thrive in damp and hot conditions and feed on dead organic material. They are adept at spreading via potting soil and transplanted plants, and their spores may be spread by visitors to botanical gardens.
The yellow parasol mushroom is also known as the flowerpot parasol, flowerpot mushroom, plantpot dapperling, lemon-yellow lepiota, or yellow pleated parasol. It typically takes 1-3 days for the mushrooms to reach their full size, after which they will decay in another 1-2 days. The fungus is not winter-hardy in most of the continental USA or Canada and is likely to die if left outside during the winter.

They can be removed with fungicide or by reducing humidity and heat
Yellow mushrooms, or Leucocoprinus birnbaumii, are a common sight in potted houseplants. They are usually small, bright to pale yellow in colour, and have caps that start off bell-shaped and open up to oval shapes. These mushrooms thrive in warm and humid environments, and their presence indicates good soil quality. While they are not harmful to plants, they can be poisonous to humans and pets if ingested.
If you wish to remove yellow mushrooms, there are several methods you can try. One approach is to use a fungicide, which can be commercial or natural. Commercial fungicides are effective at killing mushrooms and their underlying fungi, but they can also harm beneficial soil organisms and be toxic to pets and people if used improperly. Natural fungicides, such as vinegar or baking soda, can be used as an alternative. However, these methods may require multiple applications and can also affect other plants nearby.
Another strategy to prevent mushroom growth is to reduce humidity and heat. Mushrooms require high humidity, typically around 85-95%, to grow properly. By lowering the humidity and temperature, you can create conditions that are less favourable for mushroom growth. This can be achieved by increasing ventilation, using a cooling system, or reducing light intensity. Additionally, manual removal methods such as hand-picking or using a small spade can be effective for small mushroom colonies.
While yellow mushrooms may be aesthetically pleasing and beneficial to your plants, it is important to consider the safety of those around you. If you have children or pets, it is recommended to remove the mushrooms and prevent their growth by creating an unfavourable environment for them.

They are a common occurrence in potted plants
Yellow mushrooms are a common occurrence in potted plants, and they are typically not harmful to the plant. They are saprotrophic fungi, which means they feed on dead organic material and decay it into nutrients that plants can use. Their presence indicates that your soil is healthy and nutritious.
The mushrooms grow from spores, which can be introduced by contaminated soilless mixes, compost, or even be brought in from outside by humans, pets, or air. They can grow very quickly, sometimes appearing overnight, and are usually small and bright yellow, with caps that start bell-shaped and open up to become oval-shaped. They are commonly known as the "yellow houseplant mushroom", "yellow parasol", or "flower pot parasol".
While these mushrooms are not harmful to plants, they may be toxic to humans and pets if ingested, so it is recommended to remove them if you have children or animals in your home. The spores can also travel and infect other plants, so if you want to get rid of the mushrooms, you will need to remove the plant from the house, pick off all visible mushrooms, and replace the top few inches of potting soil. Alternatively, you can try to alter the conditions to be less favourable for the mushrooms by lessening the humidity or lowering the temperature.
