Common Stinkhorn.

The appearance of a stinkhorn is very distinctive: they have a phallic, white, stem structure, with a brown, bell-shaped head.

You smell it before you see it – when you smell it you just follow your nose. The unmistakable and strong stench has been likened to rotting flesh from a dead carcass. The spores of this fungus are contained within the slime that covers its cap. Flies are attracted to the offensive- smell, and sticking to their feet the spores are spread.
