Bathroom mushrooms round 2
Excuse the dog hair.
I could be wrong because I don’t see any fully developed mushrooms, but from what I can see it looks like Leucocoprinus birnbaumii otherwise known as the flower pot parasol.
It commonly grows in plant pots, feeding on decomposing matter in the soil (it’s saprotrophic). It wont harm your plants, so no worries about leaving it!
Confirming the ID: The mushrooms look yellow enough to distinguish it from the related species Leucocoprinus straminellus, which has paler mushrooms.
The caps should open up to reveal yellow gills. Once they do, cut one off and leave it on dark paper in a sealed container for about 24 hours. It should leave a white spore print on the paper.
If you had access to a microscope, the spores would shaped like an ellipse or almond-like, and would contain a large germ pore (L. Straminellus lacks this pore).
Hope this helped!
