I can find no record of Mycena subcaerulea or M. amicta occurring in Australia or New Zealand, no surprise there…

This looks the to be same as Inski’s collection from Auckland, NZ.

I don’t have the Grgurinovich book on mycena of SE Aussie (I couldn’t bring myself to spend a $130 dollars on a book that i wouldn’t use very often) If anybody does have it see if it mentions anything about blue staining mycenas.

This one should be left to Mrs.Grgurinovich

cos she is studying Mycena in Australia and has named many new species. I think it is neither nor.

Mycena subcaerulea

is an american species, first described by Peck:

Mycena amicta (Fr.) Quél. was originally described from Europe.

They can easily be told apart by the spore shape though, almost globose in subcaerulea, dacryoid in amicta

Oh, wait, M. subcaerulea is ok for N. America.

I remembered wrong it seem, M. subcaerulea is well known in N. America, there is another blue based Mycena that is only known in Europe, what was that name?

What I bearly remember…

I think that M. subcaerulea is actually a European species, that has only been assumed in N. America, or something like that. There were some notes about this in the Smith monograph on Mycena, but then again that was from 1945. Dr. Perry might have an opinion on this, or maybe Dimi, I think he has looked at European Mycena compared to California. I’ve left Mycena studies to others… I think there was a clear difference microscopically, but when they are older and brown it is hard to tell macroscopically.

And of course any of this probably doesn’t matter for a obs. from the antipodes…

Hmm, well M. subcaerulea is a North American species as well. I wonder if it or M. amicta are actually found in Australia or if this species is something distinct. Both species look like good matches, I’m not sure how you would definitively distinguish them macroscopically.

If this were North America, you would want to call these Mycena amicta. Not sure if that holds up down under.
