The ones growing in soil are not normally psilocybes, unless the soil has alder chips or cow or horse dung.
If you want you can take a spore print from one.
Choose a cap from a mushroom that has opened up.
Place it gills-down on a piece of white paper, and cover it with a glass or bowl.
Within 1 day enough spores should be released in a gill-like pattern that their color can be determined. The color is makes is the start to identifying the mushroom. Other factors are what made up th soil (what they are growing in), and the way the mushroom looks.
Don't EVER eat a mushroom without being absolutely sure. There are not many that can kill you but their are many that will leave you sweaty and shitting yourself.
I have had similar mushrooms as yours growing in my Roots Organic soil. They never seemed to be a problem. It would only happen when the pots were overwatered at night.
You can use a product like Florashield to kill it. It is a great product and can revive old plants by cleaning the soil of any fungi or bacteria.
