1. Form: This describes the overall shape of the colony. Common forms include circular, irregular, filamentous, rhizoid (root-like), and punctiform (tiny, pinpoint).
2. Elevation: This describes the profile or height of the colony. Common elevations include flat, raised, convex, umbonate (button-like), and crateriform (bowl-shaped).
3. Margin: This describes the edge of the colony. Common margins include entire (smooth), undulate (wavy), lobate (with lobes), filamentous, and curled.
4. Surface: This describes the texture of the colony's surface. Common surface descriptions include smooth, rough, wrinkled, mucoid (sticky and slimy), and granular.
5. Pigmentation: This describes the color of the colony. It's important to note both the color of the colony and the color of any pigments that may be diffusing into the medium.
6. Optical Properties: This describes how light passes through the colony. Colonies can be opaque, translucent, or transparent.
Remember: These six qualities are not exhaustive, and depending on the organism and the context, additional descriptors might be needed.
