Found these mushrooms growing in a clump of what is probably hare poop.
I think that it is a Deconica coprophila, or "dung-loving psilocybe". It used to be classified in the Psilocybe genus, but it does not show blue bruising and is non-hallucinogenic, and was moved into a different genus.
This even smaller mushroom was also growing in the same clump. I think it is the same species, but it might be a different one:
Could be - I am not 100% sure of the ID, Deconica coprophila is my best guess.
These mushrooms are very small though. Here is another photo where you can more clearly see how small they are:
