Phallus rubicundus is a species of fungus in the stinkhorn family. First described in 1811, it has a wide distribution in tropical regions. It has the typical stinkhorn structure consisting of a spongy stalk up to 15 cm (5.9 in) tall arising from a gelatinous "egg" up to 3 cm (1.2 in) in diameter. Atop the stalk is a pitted, conical cap that has a foul-smelling, gelatinous, green spore mass spread over it.
