Though many parts of Britain are currently revelling in their first snowfalls of the winter, here in my part of south Wales the white of a crisp frost is as close as we’ve got to that beauty and the only snow of note is a fungus, with the very appropriate name of Snowy disco (Lachnum virgineum).

Though there are other white cup-shaped fungi, this one can be distinguished by the hairiness of its short stem and the underside of the cup. That hairiness is also the reason you often see these tiny cups with miniscule droplets of water attached – the water ‘sticks’ to the hairs. Though these fungi are described as widespread and common, I don’t see them very often and, in fact, I only found these because I was picking up small logs in a woodland to check for any invertebrates beneath them. The Snowy disco was a very nice bonus!

Discos seem appropriate for a Friday night or, rather, they would have in the 1960s and ’70s. But my discos don’t involve a multi-colour dance floor or a flashing-ball light or John Travolta-style dancing – my discos are fungi. Getting down and dirty in Cogan Wood earlier this week, selectively picking up small logs of rotting wood for inspection, I found two of these little beauties.

Disclaimer: Fungi are notoriously difficult to identify and one thing I’ve learnt from dipping my toes into the mycological world is that one should always confirm one’s identification, especially of minute fungi like these, by microscopic examination. I have not done that so my IDs are not confirmed, just quite likely.

There are 22 species of fungi called disco, according to the British Mycological Society’s list of English Names for Fungi 2016, and they have some delightful names, mostly referring to what they grow on, I think: Larch, Conifer, Larch canker, Rush, Heath sedge, Mast, Juniper, Fir and, my personal favourite, Hairy Nuts Disco!

So far I’ve only found two. My excuse is that they’re tiny, only a few millimetres across, so they’re difficult to spot, and many are quite rare. This first one is probably Lemon Disco (Bisporella citrina), and is actually one of the more common discos. It’s a wood-rotter that can be found growing – often in the thousands – on decaying deciduous trees, particularly oak.

This second fungus may be Snowy disco (Lachnum virgineum) – like so many fungi, it requires microscopic examination for a definite ID, and I haven’t reached that level in my mycological evolution … yet! Snowy disco also grows on dead and decaying wood, and is said to be frequent, though I’ve only found it once in 18 months of foraying.
