WtF is this

As the title says.......What the Fungi is this ?

Have spotted this on dead Oaks for the last two years.

These shots are from today, last year on a different tree 8m up on a scaffold branch.

Any ideas?

Have you got a crazy artist on the loose?

Foamus expandicus

looks like yellow brain fungus to me Tremella mesenterica

That fungus is saying, "Don't come the f@@k near me or I'll have you"

Know T mesenterica as Witches butter, but haven't heard it called yellow brain fungus before. Not completly sure yet.

I remmember last year clambering around the Oak from the infamous "single tie in point" picture, when without realising my rope scraped across the fungus. It was really wet & gooey and I had to wash me rope.

Tried wiping it off with my fingers and got me digits covered in what appeared top be sulphor flourescent baby poo.....eeugh

The below is what I know as T mesentrica

looked at a few pics i'm not certain that its yellow brain fungus/witches butter, just doesn't look right to me, is is jelly like?

More wet and spongy, but looks as if a baby alien is ready to pop out and suck me face off
