Interesting,

…and thanks for your comments Karl, it’s quite a coincidence that you have commented here as I have just made a new observation of this mushroom yesterday in a conifer wood chip habitat(link below), I don’t really see the veil you mention and I am more convinced now that this is Mycena amicta or a species that is very closely related, certainly in section Amictae.

It seems that all macro and micro characters are a good match, subviscid cap with a pruinose surface, margin incurved in young specimens, separable gelatinous pellicle, pale grey-brown often with an olivaceous hue and commonly with a greenish blue margin especially noticeable in young specimens, the stipe is often quite long and commonly rooting, surface distinctly pubescent and often with a vivid blue base.

The shape and size of the spores is agreeable and also the shape and size of the cheilocystidia and caulocystidia, a lack of pleurocystidia is also in agreement.

I don’t know of any Mycena with a veil, as this one seems to possess. I checked M. amicta and it has a glabrous cutis. Perhaps you should look at Hydropus or Crinipellis?

Hi Michael Wood,

What makes you say this is not likely Mycena amicta, the microscopic features are a good match in size and shape for that species and are much closer to that than they are to M. subcaerulea which has almost round spores that are 6-8 × 6-7µm, these spores are elliptical not subglobose.

This link shows another collection from the same species from an earlier fruiting.

This collection is the same species that is shown here.

Is this not M. amicta also?

Yea its the same, amazing blue color around the cap margin in pic 82675. I see the same blue margin in obs. 21846

Odd one out

Well I still feel this is a diffrent species and doubt its even a mycena but it looks like no one is going to agree with me ;)

Hopefully,

this shows clearly enough that this is the same species that is shown in observation 21846, without a doubt a Mycena.

Well,

I guess that just goes to show how different specimens of the same species can look depending on many different factors, I can assure you that these are the same species as the mushrooms shown in the link I provided, I’ll add images in the next few days after they mature a bit more and you will see they are the same!

Your 21846 observation I agree with you but this observation looks to be a diffrent species.

Hi Clive,

No, this is definitely a Mycena species, the spore deposit is white.

These were found in a potted plant, the observation below shows specimens from the same plant from a previous fruiting!

Mycena?

These dont look very Mycena like for a Mycena…..
I would have thought these were a Cortinarius sp. see this obsevation

That was kind of you, I thought no one was going to see it when I saw all if your Lichen names:)

sorry!

Sorry to bury your observation under all the lichen taxonomy! This comment should raise it to the top…
