Clathrus archeri — AKA “octopus stinkhorn”
The young fungus erupts from a suberumpent egg by forming into four to seven elongated arms. The arms then unfold to reveal a pinkish-red interior covered with a dark-olive spore-containing gleba that smells like dead fish.
It attracts insects, especially flies that eat the mucus. The spores stick to the insects which allow the fungus to disperses and spread to other locations.
