Abstract

We study a cellular automaton (CA) model of information dynamics on a single hypha of a fungal mycelium. Such a filament is divided in compartments (here also called cells) by septa. These septa are invagina-tions of the cell wall and their pores allow for the flow of cytoplasm between compartments and hyphae. The septal pores of the fungal phy-lum of the Ascomycota can be closed by organelles called Woronin bod-ies. Septal closure is increased when the septa become older and when exposed to stress conditions. Thus, Woronin bodies act as informa-tional flow valves. The one-dimensional fungal automaton is a binary-state ternary neighborhood CA, where every compartment follows one of the elementary cellular automaton (ECA) rules if its pores are open and either remains in state 0 (first species of fungal automata) or its previous state (second species of fungal automata) if its pores are closed. The Woronin bodies closing the pores are also governed by ECA rules. We analyze a structure of the composition space of cell-state transition and pore-state transition rules and the complexity of fungal automata with just a few Woronin bodies, and exemplify several important local events in the automaton dynamics.
