  mycoderma \my`co*der"ma\, n. [NL., from Gr. my`khs a fungus +
     de`rma skin.]
     1. (Biol.) One of the forms in which bacteria group
        themselves; a more or less thick layer of motionless but
        living bacteria, formed by the bacteria uniting on the
        surface of the fluid in which they are developed. This
        production differs from the zoogloea stage of bacteria by
        not having the intermediary mucous substance.
        [1913 Webster]
  
     2. (Capitalized) A genus of microorganisms of which the
        acetic ferment (Mycoderma aceti), which converts
        alcoholic fluids into vinegar, is a representative. Cf.
        Mother.
