Could be Russula emetica, though apparently there's a bunch of red-capped, white-gilled/-stemmed Russula species out there, so really who knows. Nice mushroom to look at though, even if we can't ID down to species.
Black trumpets are kind of earthy. People say the same thing about morels though, and I don't really find them to stand out very much, despite supposedly being one of the most highly regarded culinary mushrooms. They are also pretty thin, so they cook down to a small amount compared to what you think you've picked. Still nice enough to grab a couple and sautee in butter though. They are sometimes difficult to pick out against the background of leaf litter and moss, though looking in mossy areas has seemed to be a good bet for me so far. Here in central NC they seem to fruit in late summer early autumn.
And no, I did not lick the witches' butter. They are apparently pretty bland, and there's a couple other similar species that I'm not sure I could distinguish between for purposes of determining edibility, but again, nice to look at.>>1860922
Could be, though it looks pretty old either way. I've seen a couple shelf fungi like that hang around for months or even a year or more. Probably completely impossible to ID at that point, and certainly not edible. Yours seems like it has been around for quite a while as well.
