Looks like a Stropharia species to me.

Another possibility is an old, dry Stropharia kauffmanii.
Spores 6-8 × 4-4.5 um

Stropharia riparia always has purple gills when I find it.
This looks like a good fit for Psilocybe luteonitens.
Check out p. 123 in Psilocybin Mushrooms of the World by Stamets.

Brown gills on Stropharia riparia?

Most of the photos I see of S. riparia show the gills as becoming purple-brown, on my collection, the mature gills are not as purplish as they are brown. Ah well, I am calling it S. riparia for now.

I can’t quite see enough detail in the photos, but see the page on S. riparia for a possible answer.
