Slime mold is a term of convenience grouping together several kinds of unrelated organisms. They were formerly placed in the Fungi kingdom because they produce structures containing spores (sporangia). The modern classification has them divided among several supergroups. The taxonomy of slime molds changes frequently—it is a work in progress.

Red raspberry slime mold (Tubifera ferruginosa) is one of the most commonly encountered slime molds in woodlands. It appears from June through November as a pink to bright red, pillow-shaped, tightly-packed mass on well-rotted logs, sometimes on moss. The surface is knobby, like a raspberry. It is not edible.
