If you spread mushroom compost in your garden, you need to be extremely careful and positively identify any mushrooms that appear. As inedible, wild mushrooms may also grow in the mushroom compost. Mushroom identification apps can help you with this. But if you are even slightly unsure, it’s safer not to eat them.
What type of mushrooms grow in compost?

Why do you have to be careful when using mushroom compost?
Mushroom compost should be used with caution due to its high soluble salt levels and alkalinity. These salt levels can kill germinating seeds, harm young seedlings, and cause damage to salt-sensitive plants, like azaleas and rhododendrons.
Does mushroom compost contain mycelium?
Underground roots called mycelium grow in the compost, then five weeks after inoculation, mushrooms are ready to pick. A crop continues to be harvested for three to four weeks before the bed is exhausted. After every planting cycle, the compost is removed because it is “used up,” by the growing mushrooms.
Where should you not use mushroom compost?
Mushroom compost should not be used for germinating seeds or for planting seedlings in, as before they are fully established, they can be tender to high salt levels. There are also some plants that are sensitive to salt in soils even once mature, and these include blueberries, camellias, and azaleas.
What kind of mushroom is growing in my potting soil?
The majority of the mushrooms that you see growing in your potting soil are Leucocoprinus birnbaumii, formerly named Lepiota lutea, which are small and varying shades of yellow. These are so frequently seen in pots in greenhouses and homes that the common names are plantpot dapperling and flowerpot parasol.
How do I keep mushrooms from growing in my compost?
Add fungicide to the soil.
The fungicide will kill the mushrooms and their spores, so mushrooms growing in the future should not be a worry. It may be necessary to apply fungicide a few times before all of the spores are killed, as some soil may contain plenty of spores ready to regrow at any time.
What wild mushrooms are poisonous?

Can I use mushroom compost in my vegetable garden?
Mushroom compost is suitable for most garden plants. It supports various types of plant growth, from fruits and vegetables, to herbs and flowers.
Is mycelium good for soil?
In the garden, mycelium helps to increase nutrients available to plants, improve water efficiency, reduce erosion by acting as a cellular net, and promote root growth by adding oxygen to the soil and releasing nitrogen, phosphate, and other micronutrients.
Does mushroom compost change soil pH?
Mushroom compost provides nutrients to plants, changes soil’s pH level, improves water retention and soil quality, promotes germination, and is a good top-dressing for lawns. It is particularly good for amending clay soil, but due to its high salt content, it is not beneficial to all plants.
Can you grow tomatoes in mushroom compost?
The high amount of calcium in mushroom compost is particularly helpful for plants such as tomatoes, which can suffer blossom-end rot as a result of calcium deficiency.

What happens if you eat Leucocoprinus birnbaumii?
Toxicity. Leucocoprinus birnbaumii is known to be a toxic toadstool, and if eaten it can cause a very unpleasant stomach upset.
Should I remove Leucocoprinus birnbaumii?
