Hinge and bracket

A lovely, bright and sunny afternoon for walking home down the river. By this point in the trip, I'd promised myself an ice cream when I got to the bridge, only for the newsagents there to be closed. Took a short detour to Tescos instead and picked up a Magnum, only to discover (once I was back in the sun) that the bloody thing had melted already and was like a bag of chocolate soup. First-world problems, eh?

Anyway, spotted this gloop on the way. I'm assuming it's some vividly coloured bracket fungus, but it's entirely possible some drunk student went trigger happy with a cartridge of foam insulation or something.
