Mysterious mushrooms

Found these little mushrooms growing in my chilli plant. I hope it means I’ve got a nice little ecosystem happening and it’s not some plant-killer fungi.

These don’t look like any mushrooms we eat, so can’t figure out how spores would find their way into this pot specifically. Not that we throw away gills anyway, so no reason for my compost to carry them. There’s been no sign of bird poo around this plant, but there was a tiny bird snooping around the undersides of all the leaves last week. Maybe something hitched a ride.

Anyone into mycology? Any idea what these might be?
