There are two very similar brain fungi with yellow jelly-like and both are members of the family Tremellaceae. Most often here in West Wales we come across Tremella mesenterica, which is parasistic on crust fungi of the genus Peniophora. The other is Tremella aurantia, and it is not quite so common in our area; this jelly fungus is parasitic on Stereum hirsutum, the Hairy Curtain Crust. There is little to distinguish these two, and perhaps the best way to identify them is to take a close look at the substrate they are attached to; you should find that your brain fungus is growing from the remains of some kind of crust fungus, and you now know which is which (if you know your Peniophora from your Stereum, that is! Ain't fungi fun?).
Here is a picture of Stereum hirsutum:
And here is a Peniophora species:
Incidentally, the normally reddish-brown Leafy Brain (Tremella foliacea) has a pinkish-white form that could also cause confusion; however both Tremella mesenterica and Tremella aurantia are yellow or orange (or brown when totally dried up!) so if you do come across a whitish brain-like fungus it's neither of them.
Here's hoping you have/have had a very Happy Christmas!

hi i live in baltimore md and i am pretty sure there is yellow brain fungus growing in my bathroom. I am strugglin with money right now ive had some kinda black looking mold on my window cil in my shower for about a yr now i was already scared of, not that my friend got it all out but he tried scrapping it off with paint n now its alot of old wood shown. And went i went in the bathroom this morning there it was all yellow n yucky then when we went in there this evening it had grew! I have children should i be scared help!!!!!!!!!!
Mould and other fungi in the bathroom area sign of the timber being permanently damp. If you dry out the timber thoroughly the fungi will die; then seal the surface with varnish or paint so the wood is protected against moisture ingress. Ventilation is important; otherwise fungi can feed on damp plaster. Pat.
