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?
Cross-posts:
Oh the photos just loaded.
Growing from hemlock with a darkish brown and fine spore I'd say
Hypholoma fasciculare
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.
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.
