Yellow stemmed Mycena

[SheffieldLass]

These were found in dense spruce woodland amongst the needle litter. Smell typical Mycena raphanoid. Cap and stem slightly viscid. The stem was quite rigid for a Mycena, though hollow. No coloured milk when broken.



The gills were pale, white to slightly lemon coloured, but without an obviously different or more strongly coloured edge.

Cheilocystidia with excrescences:


Clamps present


Gill trama dextrinoid, spores amyloid. Spores (8.8) 9.1-10.2 (10.6) x (5.0) 5.3-6.0 (6.4) um Qav 1.7



I'm thinking this might be Mycena citrinomarginata but only have Funga Nordica and the surprisingly undetailed description in Aronsen's Mycenas of Norway (some pics but no micro details or even spore sizes) to base the id on. As it is rarely recorded all suggestions/opinions on this welcomed.

hi Melanie

why isn't this Mycena epipterygia in one of its several varieties?

My thoughts exactly. Got a little worried that I'd been misidentifying Mycena epipterygia for the past few years!

Because I couldn't separate the pellicle so took the wrong turning in the key .... Still can't separate it, it takes the gills with it, but it is quite rubbery. But in other aspects it fits.

Thanks

Your find fits perfectly with epipterygia. The gill edge is one of the more difficult to disrupt to get a decent picture of the cystidia. The cystidia for citrinomaginata is much more simple.
The best distinguishing feature of epipterygia is the peeling cap. The only other relativley common one that peels that easy is M amicta.

You are right. The gill edge was certainly difficult to disrupt, couldn't find the cheilocystidia for ages. I think these particular fungi had been made of PVA glue ....
