I have only seen this mushroom one other time(near Olympia) but never had an interest in Mycena enough to do any microscopy. I will definitely send any blue mycena your way when I encounter them. Do you have a mailing address listed on your page?

Appreciate the information and expertise on Mycena :) You are an asset for sure!

Thanks again Sava

amicta vs. subcaerulea

Drew, these two species are easy to distinguish microscopically. The spores in M. amicta are pip-shaped, and in M. subcaerulea they are globose to subglobose. Their cheilocystidia differ too.

If you see this mushroom again, I would appreciate if you could dry it (just leave it on a piece of tissue paper for a couple of days) and send it to me. I’d be happy to scope it. A year ago I started studying PNW Mycenas and would appreciate receiving dried Mycena specimens from you and other MO collectors from our area.

Thanks Martin!

After gaining information/and images from Mushrooms Of The Pacific NW by Steve Trudell I changed my initial conclusion for this collection. I initially keyed this out to Mycena subcaerulea(blue mycena)… Which it may indeed be in the end. I am surely no expert on Mycena, but from habitat description, time of year and hairy stipe I went with M.amicta. Also, Arora lists the sub as strictly an Eastern US species.
Anyone out there with expertise in Mycena will no doubt have much more info than myself. Appreciate continued help from both Gerard and Douglas. Is Psilocybin/Psilocin an influence on coloration with this ever evolving clade of Mycena around the world? Any input is always helpful ;)

Thanks again you three!

I fully agree with Douglas,

M. amicta in the original sense has no blue cap. It can have a marginal bluish zone. And considering that every day around the world specialists describe new Mycena species (also in Central Europe like recently in Germany) I would doubt about it. But since I am not the real expert in this genus …. ;)

Hmmm…

The times that I’ve found M. amicta, it wasn’t blue on the cap. The mycelium is blue, which you can see at the base of the stipe. The cap I’ve seen has been grey mostly, and slightly brown.

Nice one, Drew!
