What is this cute green mushroom?

This mushroom is a very mysterious creature. Its green cap with white spots which is full of water and slimy, has a demonic charm that draws us, the "photographers," into its heart. Moreover, it is very small, and even if I find it once, it is so well camouflaged that if I move away from the spot, I will never be able to find it again.

Just joking.  It is actually a female plant of common liverwort, a type of moss. A moss is also cute when seen like this. It grows in a flowerpot at my home.
