I found this big glob of translucent slime on a rotting log in december. At first I wasn't sure what it was but the presence of hairy stereum - Stereum hirsutum - fungus on the same log was a clue.
Tremella - a genus of jelly fungi - are all parasitic on various crust fungi. The most commonly seen is Tremella mesenterica the yellow brain fungus, but two related fungi Tremella aurantia and Tremella foliacea both parasitise Stereum hirsutum.
I've photographed both of them before, so here they are:
I'm guessing my blob was probably a very old, decomposing Tremella aurantia...
