Green and Yellow

Bisporella citrina, Lemon Disco.  High Elms Country Park, 2 January 2017.

This odd little fungus is Lemon Disco, Bisporella citrina.  The individual blobs are very small, but there can be a lot of them.  This orange display drew me to a log by the side of a path through High Elms Country Park.

I came for the lemon disco, but stayed for that blue-green stuff on the right .. that is Green Elfcup, a fungus which is quite common, but rarely seen in fruit.  We know it's common because the wood it grows in is stained dark green even when it's not fruiting, and that is found quite often.

Here are the oddly-coloured fruiting bodies.  It's one of two possible species that can't be told apart from a photograph.

That's a great display for a mycologist, though in my opinion, rather an ugly colour ... the wood turns out quite nicely, though.  At one time, it was dried and used to create Tunbridge ware, a form of decorative inlaid woodwork.

(The title of this post, "Green and Yellow" was the title of a folk song I knew as a teenager, a version of the song more commonly known as "Lord Randal."  It did not refer to these fungi, though it could easily have done.)
