Why Is My Peace Lily Growing Mushrooms?

Mushrooms in peace lilies are a common phenomenon that many plant owners encounter. 

You can easily recognize them by seeing their small white or yellow heads with support from the soil. But why does my peace lily have mushrooms?

There are some reasons for growing mushrooms in your peace lily: 

Why Is My Peace Lily Growing Mushrooms

Waterlogged Soil:

Waterlogged soil is one of the main reasons for mushrooms appearing in your peace lily. Because if your soil is too wet or doesn’t drain well, it can create a humid and warm condition. This moist and warm environment causes mold to form and rot, which promotes fungal growth. 

Fungal spores can germinate and form mushrooms, which are the reproductive structures of fungi. They like moist soil and humid conditions. 

The more you water, the more you impoverish the soil. As a result, mushrooms will get their favorable moisture to grow well. So, to stop this you gotta take care of peace lily correctly.

If the environment surrounding your peace lily is too humid, it is easy for mushrooms to grow in the ground soil. 

Excessive water can disturb the ecological balance and increase the soil moisture. Then mushrooms have a malicious pleasure in developing. Just as the first thing you need to check when you notice this phenomenon is the soil moisture.


Do peace lilies grow mushrooms? Overfertilization can also play a vital role in growing mushrooms in peace lilies. Mushrooms like to grow in soil that is rich in organic substances. For example, if you have over fertilized with compost or with organic substances, you have created the perfect environment for mushrooms.

Peace lily does not need much fertilizer, as it can thrive in low-nutrient soils. Over fertilizing, especially organic ones, just increases the amount of organic matter in the soil, which is a food source for fungi. 

Fungi can decompose the organic matter and produce mushrooms as a by-product. They feed on humus-rich soil and grow rapidly.

Spore Contamination: 

Mushrooms produce billions of spores, which are tiny and can travel by wind or other means. It is also possible that some spores have landed on your peace lily soil from the air, from other plants, or from the potting mix itself. On top of this, if the soil conditions are favorable, the spore can grow mushrooms.

Temperature Imbalance: 

Mushrooms need a comfortable temperature to grow in peace lily soil. Mushrooms appear in Peace Lily’s when the temperature of the soil is too high.  Just like it may cause peace lily dropping, it also helps mushrooms grow.

As I said above, mushrooms thrive in warm and highly humid environments. Soil temperature between 50-68 degrees Fahrenheit is necessary for growing mushrooms. 

You should know the temperature of the soil can be different from the temperature of the air.  If it’s a warm day but the soil is cool, then mushrooms may appear in your pot or garden.

Where Do The Mushrooms Come From In Peace Lily Pot?

Contaminated potting mix is the main source of the spores that cause fungal growth in houseplant soil. But sometimes, they can also come from other means, such as air traffic or clothing spores.

Let’s see in detail: 

Where Do The Mushrooms Come From In Peace Lily Pot
  • Airborne Spores: Fungal spores are ubiquitous in the environment and can be carried by air currents. They can land in the soil of your Peace Lily through natural processes, open windows, or ventilation systems.
  • Contaminated Potting Mix: Your used potting soil can sometimes harbor fungal spores. These spores can be present in your potting mix from the manufacturer or can be introduced during storage or transportation.
  • Introduction through Water: Fungal spores can travel with water that you supply your plants. If you water your peace lily with contaminated water or if the soil is consistently moist, spores present in the water may settle in the soil. Then, eventually, it gave rise to mushrooms. 
  • Infected Plant Material: If you purchased a peace lily with infected roots or if your plant has experienced stress or damage, it may be more susceptible to fungal colonization. It leads to mushroom spores growth in your peace lily.  You gotta be careful if you grow peace lily from roots.
  • Previous Contamination: If mushrooms were present in your previous batch of soil or a different plant, their spores could persist in the environment and infect your Peace Lily’s soil. 

Also, it can happen anywhere in the supply chain: at soil production, at the nursery, at the time of delivery, you can divide a peace lily, or at the pot where you want to plant. 

Types Of Mushrooms That Can Grow In Peace Lily

There are various types of mushrooms. But not all types of mushrooms grow in the peace lily. Only a few specific types of mushrooms can grow in peace lilies. 

What are the yellow mushrooms in my peace lily? The mushrooms you see in the base of your peace lily are known as yellow lepiota (Leucocoprinus birnbaumii). They are small mushrooms that range from 3 to 5 cm. They look pale yellow in color and have a flaky texture.

  • Coprinellus micaceus: They are brown and bell-shaped and the cap becomes black and inky as it matures. If your peace lily pot has rich organic matter then Coprinellus micaceus can appear in the soil.  
  • Psathyrella candolleana: This is a mushroom that has a pale brown cap that cracks and fades to white as it ages, and a thin, hollow stem. It is also known as the pale brittlestem or the fragile dapperling. It grows on grass, wood, or soil, and may appear in peace lily pots that have lawn clippings or sawdust.
