This book describes our package of interactive computer models that simulate the way filamentous fungal hyphae grow in three-dimensional space. We call it the Neighbour-Sensing mathematical model of hyphal growth. This three-dimensional mathematical model of hyphal growth was developed to study the morphogenesis of fungal hyphal networks. The apps that make up the modelling program allow the user to change the intimate characteristics of the growing cyberfungus. Aspects like the amount of branching, angle of branching and whether cyberhyphal threads stay together or grow apart (among several...
