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.
A. parasiticus is further distinguished by its dark green colony colour. [2] [1] [7] Aspergillus parasiticus colonies are dark green. The average growth temperature for this fungus ranges between 12 and 42 °C with the optimum temperature for growth is at 32 °C and no growth reported at 5 °C. [3]
Aspergillus tamarii is a species of fungus in the genus Aspergillus. ... The growth morphology of the colonies can be seen in the pictures below.
The fungus grows at 10–35 °C with optimum growth at 30 °C. [citation needed] A. pullulans is notable for its phenotypic plasticity. 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.

Mycelium (pl.: mycelia) [a] is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. [1] Its normal form is that of branched, slender, entangled, anastomosing, hyaline threads. [2] Fungal colonies composed of mycelium are found in and on soil and many other substrates.
Fungal spores found in the body of the nail resembled the characteristic morphology of N. sphaerica. DNA sequence analysis further confirmed the identity. [16] Another case found N. sphaerica isolated from a corneal ulcer. A woman in south India was diagnosed with a fungal corneal ulcer after being hit in the eye from a cow’s tail.
Colonies of the fungus are velvety in texture and flattened (i.e., rarely raised, fluffy, or radially furrowed). C. sphaerospermum conidiophores are branched, septate, and dark, up to 150–300 μm long and 3.5–4.0 μm wide. [5] The structure of the conidiophores are tree-like, a prominent feature of the genus Cladosporium.
Colonies on culture medium may grow to several centimeters in height. Older colonies become grey to brown in color due to the development of spores. Mucor spores or sporangiospores can be simple or branched and form apical, globular sporangia that are supported and elevated by a column-shaped columella.
