Mature fruiting stage (sporangia) of a slime mold. Photography. These sporangia will then release spores which hatch into amoebae to begin the life cycle again. As it moves, plasmodium also gains nutrients through the phagocytosis of bacteria and small pieces of organic matter. Growing under bark on rotting wood in a deciduous forest. Immature sporangia emerging from the translucent plasmodium. Their common name refers to part of some of these organisms' life cycles where they can appear as gelatinous "slime".
