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.

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).

Oh the photos just loaded.

Growing from hemlock with a darkish brown and fine spore I'd say

Hypholoma fasciculare

the_artic_one @programming.dev - 1.1yr

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.

Hypholoma fasciculare

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 do not know enough to identify these, but I’m wondering if they bruise blue.

They do not — at least, not from what I can tell.
