Is clearly the correct ID here. The grey gills are the give away.

I think Stropharia possible too, Pulk.

Gills REALLY look similar, don’t they. The persistent annulus is right-on.

A couple of features not mentioned in the description seem to set this apart (I think). 1) The stipe is hollow, with a central core. The base remained attached to the substrate when plucked. I’m sorry I did not take a photo of the base.

This obs. is small. Maximum size was 3 inches. Many specimens were present, none exceeded 3 inches.
