Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
In my front garden there are Stinkhorns like the one in @Xeramtheum's photo. That area has a different type of wood mulch; could the wood itself be a host? or is it growing from the soil? or from as far as the roots of the tree which had been removed years ago?
