Question:
On the surface of the potting soil of one of my houseplants, there are a number of tiny, golden mushrooms. Can the plant be harmed by the mushrooms?
Answer:
Leucocoprinus birnbaumii, a little yellow fungus, is most likely what you see. The fungus is also known as a yellow parasol, yellow houseplant mushroom, or flower pot parasol. Although this species is most frequently found year-round alongside potted plants or in greenhouses, it can be found outside in the summer. The tiny, lemon-yellow mushrooms have 1 to 2 inch oval or bell-shaped crowns and are 1 to 3 inches tall. They could show up alone or in groups.
In the potting soil, the Leucocoprinus birnbaumii fungus decomposes dead organic debris. Living plants are not harmed by it. The mushrooms are said to be harmful to both humans and animals, though. It would be wise to get rid of the mushrooms as soon as they appear if there are dogs or young children living there. Treatments with fungicides are typically ineffective against mushrooms.
Why are the golden mushrooms on my plant growing?
A fungus is the reason why mushrooms develop on indoor plants. The fungus’s fruit are the mushrooms. Leucocoprinus birnbaumii is among the mushrooms that are most frequently discovered growing on houseplants. This mushroom has a flat or balled cap depending on how old it is. It is a light yellow color.
The soilless mix is typically the source of the spores that lead to mushrooms developing in houseplant soil. They can, however, occasionally spread through other channels, such as airborne movement or spores that rub off clothing.
When the conditions are ideal, mushrooms will typically grow on indoor plants in the summer. Houseplant mushrooms like warm, humid air as opposed to lawn mushrooms, which prefer cool, damp circumstances.
Do I need to take the mushrooms out of my potted plants?
Unfortunately, it’s quite difficult to get rid of these people for good. It will be a wait-and-see situation until you decide to evict your houseplant outright, but you have a few options when it comes to attempting to get rid of mushrooms:
- Refresh the soil in your planter. Be aware that even if you go through the hassle, the mushrooms will still come back. They are very contagious spores! Before transplanting, you’ll need to try to remove as much soil from the roots as you can, which can stress the plant out.
- Employ a fungicide. Some people opt to treat their plants’ soil with fungicides, either commercially available or home-made. Remember that it can take several doses to completely eradicate the spores.
- Remove the soil and the mushrooms with care. This is the course of action I chose because it’s simple and minimally invasive. Simply don some gloves, remove the mushrooms (stems and caps), and add fresh earth to the top two inches of the potting soil.
Whatever method of extermination you select, there’s a significant likelihood that after you’ve discovered mushrooms in your houseplant, they’ll return eventually. You might also choose to do nothing and watch them coexist with your plant. Just keep in mind that they are poisonous to both humans and animals, so it is best to attempt to get rid of them completely if there are any curious children or animals nearby.

In potting soil, what kind of mushrooms can be found?
Leucocoprinus birnbaumii, formerly known as Lepiota lutea, is the most common type of mushroom you will find growing in your potting soil. It is small and has various colors of yellow. The common names for them are plantpot dapperling and flowerpot parasol because they are so frequently seen in pots in greenhouses and homes. Small, bright yellow spheres in the soil may at first be visible, but as the cap opens to release the white spores, they will gradually fade in color. These tiny beauties have a crown that is oval in shape and around 1-2 in (2.5–4.08 cm) tall when it is not fully developed. As they age, the cap takes on a more bell-shaped shape. If you look attentively, you can see that the cap has intriguing lines and bumps in fascinating patterns. The gills on this mushroom are present, but they are not connected to the short stem.
Leucocoprinus birnbaumii toxicity levels
The name Leucocoprinus comes from the Greek words leucos, which means white, and coprinus, which was the name of the genus that, up until recently, included all of the mushrooms known as inkcaps. The majority of inkcaps have been removed from the genus Coprinus, which is now recognized as a member of the family Agaricaceae; most of the inkcaps are now included in the family Psathyrellaceae, as a result of current study based on DNA analysis. Without the stem ring, the Plant Pot Dapperling most definitely resembles a yellow Parasola plicatilis, also known as the Pleated Inkcap.
A Czech gardener who discovered this mushroom growing in a hothouse in 1839 is recognized by the specific name birnbaumii.

Toxicity
Leucocoprinus birnbaumii is a toxic toadstool that, if consumed, can result in an extremely painful stomach upset. Fortunately, the Plant Pot Dapperling grows in an unusual habitat, is small, and is so uncommon that there is little chance that fungal foragers may unintentionally harvest it for a meal.
