They were found in mid-november in the Salish Coast region of Cascadia. They were growing out of woodchips composed of a mixture of western hemlock (majority), and western red cedar.
Side view of one full mature specimen:
A group with a sample of the substrate (the cap appears to be umbonate):
A closeup side view, and internal view of the stem (it appears to be hollow):
Cross section of the gills — they appear to be adnate, or sub-decurrent:
Underside of view of the gills:
Spore print (first on white background (the split is due to two halves), second on a black background):
Examples specimens once dried:
Examples of the colony, and the location/substrate in which it was growing:
My initial thought was that they were Psilocybe cyanescens, but that’s pretty much completely been confirmed as incorrect. The current running theory is that they are Hypholoma dispersum. What do you think they are?

Do you have a spore print? What color do they bruise? What trees were nearby?

Hmm. I at least don’t think that it’s fasciculare. The stipe should have a collar [1.1] (though, I question this as none of the images I see seem to shop a collar), which this doesn’t. The caps should be convex [1.1], which they aren’t — the babies are somewhat, but the mature one’s are wavy. From the picture’s that I’ve seen, the color is also off — they’re shown as more yellow [1.2][2], where this one is not yellow — the color of the specimens that I’ve observed is, in general, very different.

I agree with hypholoma but fasciculare doesn’t have white fibrils on the stipe like some of those do. Dispersum is a better match IMO.

Not having the mushrooms directly at hand your estimation is as good as mine.
