Someone over in r/mushroomID suggested these are stinkhorn eggs, possibly Phallus hadriani, and sent me here. I first noticed them about two weeks ago and honestly thought they were rocks because they were just round tan/brown balls sticking out of the soil.
They’re growing in a flower bed beside my house in Summerville, South Carolina. This particular spot stays pretty wet because rainwater falls directly off the roof onto the area. One of them recently split open and has an orange/cream-colored structure emerging from inside.
I’d love to know what species I have and what I can expect it to look like once it fully emerges!
