The jury is still out on this one…

I will scope it tomorrow! There had been quite a bit of rain, and amounts of cap debris and stipe slime coats would change accordingly. It looks like a dead ringer for the Norwegian rorida material, here:


And yes, IF it is rorida, the genus has been changed, from Mycena to Roridomyces. Guess the mycena-ologists also thought it was a weird fit in mycena!

not rorida… but probably mycena

I would say this is probably not rorida! I have collected that species many times and it has a very thick layer of slime on the stipe (about twice as thick as the stipe itself!) and a granular pruinose cap center! It also should be in the genus mycena anymore… it does have the stature of that species though! the slightly decurrent gills and cap shape is consistent with mycenas but also could be some strange omphalinoid…

I beleive in Mycena

The shape of the cap and gills looks like it does in Mycena rorida, the rest reminds more of Mycena vulgaris, another one with a slippery stipe, but not quite that pronounced cavity at the top of the cap. I don’t know the mycenas well enough to suggest any species here.

Well, looks to not be Rickenella swartzii

I had remembered that there was a common eastern Rickenella, but this isn’t it. There is Rickenella swartzii in the east, and Europe, that grows with moss beds. It has a darker stipe and cap disc than this one, also yellow-olive tones when young. These are on leaves, no moss, lighter, no yellow-olive tones…

Still, I don’t think they are Mycena, the cap shape is just wrong.

Sure it is Mycena?

The gills look decurrent, I don’t think that is supposed to happen in Mycena. These might be Rickenella, or maybe Marasmius?
