This is what Junghuhnia (Steccherinum) nitidum - probably - looks like from a distance when the fallen branch it is growing on is propped up against a neighbouring sapling. I think the extensive fruiting patches indicate some quite dominant decomposer activity by this particular species.
Some neat patches of this rather excellent poroid crust, found perhaps unseasonably in April.
This area here shows water drop magnification of the pores!
