Aseroe rubra, commonly known as
the anemone stinkhorn, sea anemone fungus and starfish fungus, is a
common and widespread basidiomycete fungus recognizable for its foul
odour of carrion and its sea anemone shape when mature.

It produces its spores in a nasty-smelling slime that attracts flies and
other insects, which crawl around in the slime, picking up the spores
on their feet and dispersing them on whatever the flies land on. Gross,
but pretty cool stuff!

It’s not edible in any way shape or form.
