Abstract. A computer model of the fungal colony that grew consuming limited amount of nutrient with three control parameters, growth rate, and nutrient level and diffusion, was constructed to make a basic morphology diagram of mycelial colony. To apply the diagram with those parameters to the mycelial growth of Aspergillus nidulans wild and mutant strains, the relation between the colony expansion and the nutrient level was measured. Differences in the colony patterns of these strains at low nutrient level were attributed to the change in the above relation that caused a shift of the corresponding patterns in the diagram.
