Remains of a Brain Fungus

What I think is remains of the crystal brain fungus Myxarium nucleatum (= Exidia nucleata) on a fallen twig. 

The white lumps are the calcium oxalate inclusions that are often visible in younger specimens (see here for example) and the brown film is the remains of the whiteish translucent fruiting bodies.  To quote from the Wikipedia page: "With age the fruit bodies may become brownish and eventually dry to a thin, varnish-like film".
