Colony morphology may be affected by carbon source, colony age, temperature, light and substrate, with colonies ranging from homogeneous to sectored, yeast-like to filamentous growth, and from small to large.
The shape and structure of a colony can be impacted by factors such as the type of nutrient available, the age of the colony, environmental temperature, light exposure, and substrate composition. Colonies can exhibit a wide range of characteristics, including uniformity, segmentation, yeast-like or filamentous growth, and varying sizes.
