These were found in Cascadia in mid-November. What are they?

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 [1][2][3][4][5]. The current running theory is that they are Hypholoma dispersum[2][3]. What do you think they are?

[…] I’m sorry to disappoint you, but even though they look similar to P. cyanescens, they aren’t.

Cyans have white-ish stems, dark gills, a purple-black spore print and bruise blue almost instantly when touching them. […]

Sorry to disappoint but looks like hypholoma dispersum to me.
- there’s no blueing on the stems or margin in any of your photos, the ones you picked should have had stained blue anywhere you touched them
- The margin isn’t translucent striate
If the cap cuticle is peelable you could make a case that it’s not Hypholoma but without any blueing it’s gonna be Deconica not Psilocybe.

That’s consistent with Hypholoma, maybe next time.

[…] If I would see even a tiny speck of blue bruising I would be more inclined to agree with P. cyanescens, but I don’t see any at all, which makes me very suspicious. […]

the spore print is also brown here, but should be purple-ish black if it were Psilocybe spp., also the stipe looks wrong for that ID - I would say definitely not Psilocybe cyanescens (not just because they’re not bruising blue / purple / black).
