Lycogala epidendrum

Lycogala epidendrum, commonly known as wolf's milk, is a species of slime mould which is often misidentified as a fungus. Lycogala epidendrum fruits in forests on damp rotten wood during Summer and Autumn. When not fruiting, they live as small amoeba-like organisms that get their nutrition from the rotten wood.

Immature fruiting bodies are entirely a bright pink/orange colour, and when damaged, the slime (actually the cytoplasm of a large single cell) oozes out. When mature, the fruiting bodies are dark grey, up to about 1 cm in diameter, and full of minute grey spores.
