I have no idea what’s the name of this one.
Edit: Thanks to the info from @rozlav@lemmy.blahaj.zone, this is the Stropharia caerulea, commonly known as the blue roundhead.
Edit2: Another update on what we are looking at thanks to @oftheair@lemmy.blahaj.zone: It might also be Stropharia aeruginosa, commonly known as the blue-green stropharia
Are you sure it’s not: https://en.wikipedia.org/wiki/Stropharia_aeruginosa ?
