Very cool photos! No ID from me but looks like a neat little world there.

Looks alot like dead mans finger aka Xylaria polymorpha just guessing tho! 😅

I’m pretty sure the fingery stuff is Xylaria hypoxylon - candlesnuff fungus (dead man’s fingers is usually chonkier / more rounded at the end and darker colour). I don’t think the orange stuff is slime mould - looks like slime flux or something fungal to me.
