Model description . (a) A longitudinal-tangential section of Norway spruce wood is characterized by the cellular structure of the tracheids. The principal directions of wood are usually termed as longitudinal, radial and tangential, denoted by the letters L, R and T. The pits are the substrate for the fungus (i.e. nutrient points) and distributed with a density ρ on the substratum of the fungus (i.e. tracheid cell walls) by using uniform random numbers. (b) The mycelium is modeled as an assemblage of edges, nodes and tips. The evolution of the mycelium is characterized by a pit-to-pit growth of the fungus. Details about the model construction can be found in Fuhr et al. (Fuhr et al. 2011a).
