but so were some gyms I tested. Melatonin tested positive.

No Idea really. I have specimens en route to Scott Redhead who sounded pretty interested in the find. Hopefully he’ll have something to add to the conversation. Right now I’m thinking the stipe flesh is actually not blue, but an optical effect from the color of the outside makes it look that way.

Could it be a bacterial infection?

Like Cuphophyllus virgineus “var roseipes”?

Maybe he’s right.

I have learned more from A. Rockefeller than from any other mycologist. I don’t doubt him, but I don’t think he conclusively knows.

I’m not a chemist and I’m still learning fundamental chemistry. However, if one or more species in the genus Flammulina contain significant levels of the chemical Tryptophan (or L-Tryptophan) – and L-Tryptophan is a precursor to psilocin – then I see no reason why Flammulina species can’t evolve into psilocybin-producing fungi.

seem typical for F. velutipes. Alan Rockefeller is certain that the color is not an indication of psilocybin/psilocin.

In regard to what’s causing the color…

…I think you should have some material processed at your local university using GC/MS (gas chromatography/mass spectrometry) or UHPLC/MS (Ultra high performance liquid chromatography/Mass spectrometry).

Otherwise, we may never know.

Can you describe the aroma of this collection?

Have you nibbled a tiny piece and spit it out to get the taste?

Excellent, thanks!

I’m not going to eat them,

though it is tempting. I’ll be doing some micro work on these shortly and will make dried specimens available. Do you know of a micro key for Flammulina?

This is an important collection(!). Please take several spore prints on tin foil and save them. Please also dehydrate at least six specimens and submit them to an internationally accessible herbarium.

I would get spore prints out to several Trusted mycologists.

Luckily these are at a location very close to me and I will most definitely be monitoring the spot for future growth. I’d be lying if I were to say that I wasn’t curious about performing a bioassay.

All I can say…

…is please take several more photos and check for a second harvest!
