Found in mid-November in Cascadia. What are they? Please see the description for more information. (sh.itjust.works)

View the spoiler for my guess at what I think it might be, but please first come to your own conclusion before looking at mine β€” I don't want to bias your guess.

My guessPsilocybe cyanescens

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 β€” 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:

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.

For clarity, are you saying that all species in the genus deconica have a peelable cap cuticle?

[–] [email protected] 2 points 4 months ago (1 children)

It's probably not 100% absolute but most Deconica and Psilocybe have a peelable cuticle to some extent.

[–] [email protected] 2 points 4 months ago (1 children)

I gathered another sample of the mushroom, and, from what I can tell, the cuticle is not peelable/it has no pellicle.

That's consistent with Hypholoma, maybe next time.

Very great report! We need more of those similar to that!

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.

Good luck next time! :)

Thank you 😊 I tried to provide as much useful information as possible (that I could think of, anyways) to aid in identification. I would've also provided an image of the spores, but I don't currently have access to a microscope of sufficient magnification to image them.

Do you have any recommendations, for future reference, for other bits of information not mentioned that would aid in identification?

I would've also provided an image of the spores, but I don't currently have access to a microscope of sufficient magnification to image them.

That's really great! I also have a (pretty good) microscope at home, with one of its' purposes being exactly that. But I believe 99% of people out here, myself included, probably couldn't discern the spores microscopically anyway, so that being missing won't matter much or at all.

Maybe you could optimise the spore print picture.

I personally like to take the prints on aluminium foil, because

  1. It gives okay contrast for both bright and dark spores.
  2. It's cheap
  3. It's almost sterile and can easily be disinfected
  4. You can store the prints better by folding the foil.
  5. You can ship and share the prints way easier without risks (microscopy slides breaking, paper soaking up, etc.)

For identification, when I need someone's else opinion, I like to take them thrice.
1x aluminium foil (to see the color)
1x black paper (if whiteish)
1x white paper (if darkish)
1x glass (microscopy slide, mirror, etc.)

I sometimes find the colors on pictures a bit misleading, because most people take them with their phone, which like to manipulate the picture (weird color corrections, sharpening, AI, etc.) and are too dark.

Optimally, take them somewhere under a light with normed values (e.g. some LEDs or fluorescent lights give off "office light" or "daylight"), where the white balance can easily be adjusted.

Or, you can add some objects with known colours for reference, e.g. something like those take-things moviemakers use, certain LEGO bricks, and so on.

But nothing I said is meant as criticism. Not at all. Your post was great! Take it as inspiration, maybe it will help someone :)

Neat Idea to use aluminum foil! I'll have to try aluminum foil next time. I also hadn't considered physically storing the prints for future reference Β­β€” it likely would make sense to do so.

Good idea about lighting/white balance. I will try to improve the color accuracy in future images. I could potentially just capture the image RAW for future adjustments to color.

I believe 99% of people out here, myself included, probably couldn’t discern the spores microscopically anyway, so that being missing won’t matter much or at all.

I figured that it'd be worth it to include it, at least for documentation purposes, if not for the potentially unlikely case that it does aid identification in some meaningful way.

[–] [email protected] 1 points 4 months ago

1x black paper (if whiteish)

I tried accomplish this end by simply coloring a spot on the paper black for contrast (as seen in the image in the post). It certainly isn't perfect, but I think it served its purpose. That being said, purchasing some black paper for this purpose is likely a much better idea.

[–] [email protected] 1 points 4 months ago

1x glass (microscopy slide, mirror, etc.)

I've done this before, and it worked well, but I was unable to locate any when I was trying to ID this. Perhaps I should just purchase a bulk amount of cheap glass slides for this purpose to store prints on?

[–] [email protected] 2 points 4 months ago

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

Would you by chance have a guess as to what they actually might be?

[–] [email protected] 3 points 4 months ago

Not an expert, but I think these are mushrooms.

[–] [email protected] 1 points 4 months ago (1 children)

Cyanescens?

[–] [email protected] 1 points 4 months ago (1 children)

For clarity, do you mean psilocybe cyanescens?

[–] [email protected] 2 points 4 months ago

I did but, probably not based on the other comment.
