PHASE  TRANSITIONS  IN  IMPERFECT  MYCELIUM
FUNGUS  COLONIES

Institute for Analytical Instrumentation RAS, Saint-Petersburg

    The process of imperfect fungal colony self-organization may follow three main strategies: "continuous lawn", "ring structures" and "colony dying" [1]. The relationships between these strategies and the strategies themselves can be described in terms of phase transformation theory which was developed primarily for ther-modynamic problems [2]. The analyzed phase transformations of the "dying" and "continuous lawn" strategies have the features of phase transitions of the first and second kind. Nevertheless interpretation of the "ring struc-ture" strategy proper with these transformations is ambiguous.
