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.
The medium Sabouraud's dextrose agar is commonly used for colony growth and is treated with antibiotics to prevent bacterial contamination. [5] Colonies growth is usually observed in 1–2 weeks at 25 °C. Identification using polymerase chain reaction is also possible, this provides an accurate rapid diagnosis. [8]
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.
Trichophyton rubrum is a dermatophytic fungus in the phylum Ascomycota.It is an exclusively clonal, [2] anthropophilic saprotroph that colonizes the upper layers of dead skin, and is the most common cause of athlete's foot, fungal infection of nail, jock itch, and ringworm worldwide. [3]
Rhodotorula mucilaginosa cells, Methylene blue stain, magnification 400x. Rhodotorula is a genus of fungi in the class Microbotryomycetes.Most species are known in their yeast states which produce orange to red colonies when grown on Sabouraud's dextrose agar (SDA).
Conidia and colony characteristics of the culture led to identification of N. sphaerica as the fungal pathogen. It was hypothesized that this special case of fungal corneal ulcer was caused by transfer of spores to the patients eye from contamination with soil (a common habitat of the fungus) or other matter from the cow’s tail.

This fungus is readily distinguished from the other species of Aspergillus by its cinnamon-brown colony colouration and its production of aleurioconidia. A. terreus is a thermotolerant species since it has optimal growth in temperatures between 35–40 °C (95–104 °F), and maximum growth within 45–48 °C (113–118 °F). [13]
