Mycena at Botanic Gardens

A week or so ago we came across this pretty looking mushroom on a Tuesday walk. Growing under a beech tree, it was assumed to be another patch of Amethyst Deceiver, Laccaria amethystina, which is quite common here. But alongside was a Beechwood Sickner, Russuala nobilis, which I then bent down to take a photo of. Having got closer it could be seen that it wasn't L. amethystina at all but a Mycena spp. This time I assumed it was the Lilac Mycena, M. pura, took a photo and put it in my box to take home. Only recently I've got around to looking at it and it would appear not to be M. pura after all but could in fact be M. diosma, which is a lot rarer with only a very few  Welsh records on the BMS database.

Another mistake on the same day was assuming that this polypore mushroom, growing in Trawscoed wood was "Hen of the Woods", Grifola frondosa, when checking it on the internet it would appear to be the Giant Polypore, Meripilus giganteus, which seems to sum up my fungus foraying as what you find is never what you think it is!


  1. Crikey. Not Hen of the Woods? Oh dear, I was sure it was. Tudor Davies, one of the horti team, said he'd seen Meripilus on Woods of the World two weeks ago.

  2. Excellent species! I think the Mycena is 'diosma' (I have a thick Italian book!!!) and the zoned marking at cap edge is typical and often the stipe grooved (do not see this). The gills 'violet-pink' with white edge. I have only seen Meripilus at Aberglasney --- there for a few years till the tree stump was removed.
