Colonial morphology of various specimens of Pseudomonas aeruginosa, including mucoid types. In microbiology, colonial morphology refers to the visual appearance of bacterial or fungal colonies on an agar plate. Examining colonial morphology is the first step in the identification of an unknown microbe.
B. wadsworthia must be incubated on BBE agar for at least 3 days in order to see colony formation. Two types of colonies appear. A 1-2 mm diameter convex and irregular colony with a black center [5] or a translucent umbonate and circular colony with a dark center. BBE agar is the optimal agar for B. wadsworthia colony growth.
Caps that possess this feature are called umbonate. Umbos that are sharply pointed are called acute, while those that are more rounded are broadly umbonate. If the umbo is elongated, it is cuspidate, and if the umbo is sharply delineated but not elongated (somewhat resembling the shape of a human areola), it is called mammilate or papillate. [1]
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. [1] Colonies can form in various shapes and ways depending on the organism involved.
The shape of the pileus in Filoboletus hanedae displays quite a bit of variation with convex or conico-campanulate, umbonate, plane, hygrophanous caps being observed. Margin rather strongly incurved at first. The underside of the pileus has pores, rather than gills, where spores are grown and dispersed.
The thallus of Metamelanea appears blackish and has a cracked, areolate texture, meaning it is divided into small, island-like segments called areoles. The thallus is composed of densely packed rows of lichenised colonies containing a single-celled cyanobacterium (blue-green alga) as the photobiont. These colonies are surrounded by fungal ...

Cortinarius violaceus has a convex (becoming broadly convex, umbonate or flat) [13] cap of 3.5–15 centimetres (1 + 3 ⁄ 8 –6 in) in diameter with an incurved margin. It is dark violet to blue-black in colour, and is covered in fine, downy scales. [4]
