slime mold

n.
1. Any of various eukaryotic organisms of the class Dictyostelia that exist as free-living amoeboid cells in the soil and under certain conditions aggregate into a mass that develops into a stalked sporangium. Also called cellular slime mold.
2. Any of various eukaryotic organisms of the class Myxogastria (formerly Myxomycetes) that develop from amoeboid cells into a large multinucleate plasmodium that produces stalked sporangia. Also called myxomycete, plasmodial slime mold.

n.
any of various funguslike organisms belonging to the phylum Myxomycota of the kingdom Protista, characterized by a somatic ameboid phase and a streaming phase in which the separate organisms merge and produce spore-bearing fruiting bodies. Also called myxomycete.

slime mold

Any of various primitive organisms that exist in both unicellular and multicellular stages and are found on decaying plant matter. Slime molds are classified as protists. ♦ Cellular slime molds live as single, amoeba-like cells moving about feeding on bacteria. When food becomes scarce, they combine into large colonies that develop into multicellular, spore-producing structures. ♦ Plasmodial slime molds exist as a mass of amoeba-like protoplasm (called a plasmodium) that contains many nuclei within a single cell membrane. The slimy masses move along ingesting bacteria and yeast. When food grows scarce, they stop moving and grow multicellular, spore-producing stalks.
