Yellow Brain Fungus

A yellow brain fungus, probably Tremella mesenterica, on a birch twig (I think).  According to Sterry and Hughes (Collins Complete Guide to British Mushrooms and Toadstools, 2009), T. mesenterica is parasitic on the mycelium of Peniophora fungi.  The similar T. aurantia parasitizes the mycelium of Stereum hirsutum.

That's beautiful. I found something similar growing on birch and concluding T. mesenterica as well. Any chance you saw either of those hosts? Mine was on a bare log.
