  Describe the form, elevation, and margin as indicated in Fig. 1. Also indicate whether the colonies are smooth (shiny glistening surface), rough (dull, bumpy, granular, or matte surface), or mucoid (slimy or gummy appearance).

  Breakwell et al. describe colony form as one of the primary macroscopic morphology descriptors recorded for well-separated colonies on solid medium.

  FIG. 1. Diagram illustrating the various forms, elevations, and margins of bacterial colonies (3).

  The ASM protocol separates colony forms from elevations and margins, supporting this record as the colony-outline component of colony morphology.
