'Probably' Mycena rosea



Mycena pura



Typical M. rosea



According to Nick there is very little difference microscopically.

Just to 'muddy' the waters a bit - that top shot 'rosea' has set me thinking (always a dangerous thing to do is thinking!) but I have shots here from several years ago that look extremely like this and I was told they were a colour form of Parrot Waxcap' H. sittacina var perplexa ............ I may be able to find the actual image later but must go just now .......

Hi Pauline

Perhaps you mean this image?



I think we may have discussed this before. You can see that the cap and stem are distinctly viscid, which rules out Mycena pura. It is Hygrocybe psittacina, but not var. perplexa. It is just a pink variant. H. psittacina var. perplexa as described by Boertmann is 'brick-red, rust to dark brownish red'. The image he shows is quite different from the pink variants that occasionally turn up. (I believe you had your confirmation of this variety from an authoritative source, but I would consider Boertmann to be the authority on this genus in northern Europe.)

I think specimens with this type of appearance may muddy the waters because without clear microscopic distinctions it is difficult to put them firmly into one species or the other. Personally I would call these Mycena pura.

PS There was a thread last year which discussed some of the differences between the two species.

True Ken, and maybe I should have used the word 'possibly' rather than 'probably'!

Looking back at our earlier thread I think there is still much doubt in many cases.

Looking at my images of 'M. rosea from Clumber over the years I concluded that this species was very common in leaf litter amongst Lime, whereas M. pura was generally found in the presence of Beech and Birch.

Whether or not there is any significance to this I'm not sure

Apart from the very slight difference microscopically between them I think we can 'safely' say that in general M. rosea is a larger, more robust species and profoundly pink in colour.

Another likely 'physical' characteristic of M. rosea may also be it's cap as shown in the larger fruit body show here.



but then ....

Hello Ken - yes the very one! I'd forgotten we spoke about this back then (think I'm slowly going the same way as my mam and seeing how she's 80 perhaps I shouldn't panic about that too much!) Yes it was what I call an authoritive source but perhaps he was having an off day?!!! I seem to get a lot of those now ........ Thanks for reminding me - I willl rename them in my files and then I don't keep making the same mistake

No, not more, I just need to see the same 200+ species in the hope that I might remember more of them second time around...

I'm in the same situation as FungiJus, next year's diary already beginning to get a few dates for the autumn.

Therefore I've done the dirty deed and started the Clumber 2011 thread.

Just a quick reminder of an excellent find by Mal

Marasmius setosus
