Myxomycetes \Myx`o*my*ce"tes\, n. pl. [NL.; Gr. ? mucus, slime +
   myceles.] (Bot.)
   A class of peculiar organisms, the slime molds, formerly
   regarded as animals (Mycetozoa), but now generally thought to
   be plants and often separated as a distinct phylum
   (Myxophyta). They are found on damp earth and decaying
   vegetable matter, and consist of naked masses of protoplasm,
   often of considerable size, which creep very slowly over the
   surface and ingest solid food. -- {Myx`o*my*ce"tous}, a.
