Wolf's milk (Lycogala epidendrum)
Wolf's milk or Groening's slime (Lycogala epidendrum) is a slime mold which feeds on microscopic organisms, such as bacteria or fungi, and is commonly found on decaying wood. Although slime molds may superficially resemble fungi, these life forms are now known to be unicellular organisms in the unrelated Protista kingdom. Nevertheless, they are frequently encountered by mycophiles (mushroom enthusiasts), and are therefore included in a number of mushroom field guides.
