Identified as Phallus ravenelii from the white stalk and relatively smooth to finely granular cap surface. Examine the cap beneath the slime when comparing similar species.
Phallus impudicus has a deeply pitted and ridged cap beneath the slime. Mutinus stinkhorns lack a separate cap: their slime forms directly on the upper stalk.
Woodlands, garden beds and decaying woody material. Often fruits in late summer and fall.
The fruiting body emerges from an egg-like structure. Its strong-smelling spore slime attracts insects that carry spores away.
The stalk expands from a rounded immature structure.
Insects help move the spores.
The surface beneath the slime helps separate similar stinkhorns.
