Not good or bad really. Mushrooms fruiting in your soil suggests you are keeping the mix moist. Having fungi suggests healthy soil albeit a little too moist possibly for a bit too long. Mycorrhizae is what you want in your mix for symbiosis but it’s possible to have many different varieties of fungi in a healthy soil mix. Could have something to do with ambient humidity so if it’s really humid in the grow area mold could be a concern. I’d pull those mushrooms and toss em before they throw spores but otherwise do as you are doing. Maybe let the soil dry out a bit before next watering.
