yeah i was a bit surprised myself finding it in dirt, i thought mycenas were decomposers of sticks and twigs, etc
wood anyways…

but it definitely was just in the soil, there was no wood underneath.

the one “r” was cause i started to type it in, and thats what popped up in the yellow bar below it as a suggestion (or previously typed), so i figured i probably misread the name in the past.

cyanorrhiza doesnt grow in north america? well damn that about clears that up then doesnt it.

hard to find info on them.

thanks everyone.

Ok, found it in A. H. Smith

There is a listing of things in A. H. Smith “North American species of Mycena” (1947). It seems there is a subsection there on bluing Mycenas, and the only two listed for North America are M. amicta and M. subcaerulea. It also mentions that M. amicta is found on conifer wood, and is common in the Northwest, and uncommon in the Northeast. M. cyanorhiza he mentions as a European species that does not occur in North America. (Also he has it as one ‘r’, and I guess others have it as two ’r’s, ah, the rhiza or rrhiza quandary…)

So, it looks like the blue “staining” Mycenas in the Northwest should get called M. amicta. Strange you say it was found on the ground… it should have been on conifer wood, like a well rotted log.

blue reaction…

I’ve seen with Mycena amicta, that the mycelium at the base was white when obs., and then I grabbed a few a put them in the box, and by the time I got back to the ranch, the mycelium at the base was bright blue. This wasn’t a “bruising” reaction, the mycelium seems to turn blue after picking, in some oxidation reaction.

This was Mycena amicta, which I’ve seen here there and around, but this one I’ve only seen on wood, and well rotted logs, and I think mostly conifer. I’ve seen a bunch on a red fir stump, and some on a log under a spruce tree, and some in a spruce/d. fir/redwood mixed forest. Not sure if conifer only is a true statement.

This species here M cyanorrhiza I’ve never really heard of though, and it would be good to know where some good description of this species is published somewhere… I’d like to know how do you know this one is separate from M. amicta. A few things, these were found on the ground, so that doesn’t match M. amicta, and the caps are too large large compared to the M. amicta that I’ve seen, which were small guys, with narrow light grey to off-white caps.

If you are really interested in random blue staining reactions, you should spend your time on the boletes, where large edible species display lots of blue staining reactions, and much stronger than what you show here.

ok well….

the base of these was normal when i picked them, apon squeezing the base they turned a winter-green/green color, and faded into a minty-blue color seen in the photos by the time i returned home from my hike in the rainforest.
they were not blue to begin with.

its just blue

My guess is that these things are just blue and it is not caused by psilocin. I could be wrong but I am going to call these inactive until I see a reliable report.

A lot of these inactive blue mushrooms start out very blue and fade as they get older, and do not bruise blue where damaged.

Mycena is not a very dangerous genus, but maybe thats because no one ever eats it. Several species contain muscarine though probably not in high amounts. If you are curious as to the chemical content of this species I suggest testing with paradimethylaminobenzaldehyde.

hmm

well that clears up a lot Dan, thanks for that.

what does one need to do to “publish” this information?
would eating some and reporting back be a good enough indication?
i see these every now and then.

so, without a published bioassay of the chemical contents of this mushroom…

…the answer to my question is, “I don’t know what makes it blue?”

Guzman, Allen, and Gartz (1998)

Worldwide Geographical Distribution of the Neurotropic Fungi

I could not find the 1992 Allen and Gartz paper cited by Stamets, but I did find this later paper which mentions Mycena. “Psilocybin… [is] also found (or probably found) in some non-bluing species of Agrocybe, GalerinaMycena…” (page 198).

Mycena cyanorhiza (Quel).” appears in the species list on page 203.

I only skimmed the paper, but I could not find any other mention of Mycena.

The “(or probably found)” coupled with a lack of documentation makes for a very weak claim.

My understanding of the Stamets quote is that an anecdotal story about a single person’s two bioassays of a blue Mycena was reported in a paper that both Allen and Gartz co-authored. I don’t think Stamets is claiming that Gartz tried the mushrooms himself. If Gartz were going to make a claim about the presence of psilocin or psilocybin in a Mycena, he would have done a chemical analysis like he has done for so many other species of mushroom. Maybe the study exists, but I could not find it.

I suspect the claim about psilocybin activity in Mycena is Allen’s alone, even though it appears in a paper coauthored with Gartz.

they were found growing from dirt, under Salal bushes.

i do not recall the trees there, but it was your typical Pacific Northwest Coastal Forest.

most likely a dense mix of douglas fir, pines, alders, and hemlock.

How did you get this name?
By: Douglas Smith (douglas)
2008-12-10 19:55:53 CET (+0100)

This name is a new one on me, how do you get this name, and how do you determine this to species? Also specifically differ from Mycena amicta? What was the habitat for these? On wood, ground, under what trees?

I don’t see this listed as a species found in California from the monograph by Dr. Perry here. I can’t see much about these on the web either. I did find a mention in the book “Psilocybin Mushrooms of the World” P. Stamets, A. Weil :

Quote:

Despite repeated analyses … no psilocybin … was detected in
collections of M. amicta, M. cyanorhiza, M. pelianthina or
M. pura.

Nevertheles I have heard several anecdotal accounts of activity
from people ingesting Mycenas, … Allen and Gartz (1992) reports
on a personal bioassay resulted in psilocybin intoxication on
two occasions … a “Mycena cyanorhizza” and unid. Mycena, likely
M. amicta.

/Quote.

Which doesn’t sound like something that really should have been published… and I guess taken as seriously as it was reported or studied here…

I’d like to know more about how one knows they might have found this species here.

Are you denying Jochen Gartz’ experience with these also?
i know mjshroomer holds about as much credibility as a sieve, but Gartz has yet to screw with our heads.

I doubt the reports of psilocin in Mycena
By: Dan Molter (shroomydan)

Psylocybin Mushrooms of the World contains a report of John Allen tripping from eating blue Mycenas, but John has refused to confirm the story. I doubt its authenticity.

i dont know if any DNA analysis has been done on these, but i do know John Allen (mushroom john, mjshroomer), and Gartz, have both bioassayed these mushrooms, and confirmed psilocybin intoxication.

what causes the bluing rxn?
