These are in the genus Psilocybe, microscopically very close to Psilocybe cyanescens. The collection you are confusing it with is here.

Galerina species…

Weren’t these identified as a bluing galerina species?

There are plenty of Psilocybe with chocolate brown (or some variation of medium brown) spores.

Alan has a ’scope, myabe I can convince him to do some microscopy and take some photos.

Spore details?

I’d like to see a photo of the spores of these posted, the gills are rather light toned for a Psilocybe, although there are a few with light colored gills…

Yes, they were found growing from woodchips under a shrub in a very well irrigated area.

The stipe is whitish, the pileus is caramel to orange-ish, hygrophanous fading to light tan, striate, convex. Lamelle are light brown, blue staining reaction on cap and stem.

those specimens are very interesting indeed, they resemble Psilocybe Stuntzii with the way the leftover veil remnants have cause bruising around the cap margin there, but they also slightly resemble Cyanescens.

was there any information as to what substrate these were growing from?
