Coloured scanning electron micrograph (SEM) of a partly open fruiting body from the slime mould Lamproderma lycopodia showing the spores (dark brown) and the capillitium (yellow). The spores will germinate into free-living, single-celled amoeba. The amoeba aggregate to form a plasmodium, a large single cell with multiple nuclei. The plasmodium can move slowly, feeding on bacteria, fungi and decaying matter. In poor conditions the plasmodium forms fruiting bodies and the life cycle begins again. Slime moulds were once classified as fungi but are now classified as protozoa. The fruiting bodies of Lamproderma lycopodia are only found on the leaves of clubmosses (Lycopodium sp.). Specimen from the Black Forest National Park, Germany. Magnification: x1,700 when printed at 15cm wide.
