Which of the following is an example of hyaline (non-pigmented) fungi?

• A. Candida albicans
• B. Fonsecaea pedrosoi
• C. Cladophialophora bantiana
• D. Exophiala dermatitidis

Answer: (A)

Hyaline fungi are those with light-colored, non-pigmented structures, meaning their hyphae and colonies appear pale or cream rather than dark. Among the options, Candida albicans fits this description because it is a yeast that forms cream-colored, non-pigmented colonies and does not produce dark melanin in its cell walls. The other three are dematiaceous fungi, which contain melanin in their hyphae and/or cell walls, giving them dark brown to black appearances. So the best example of a hyaline, non-pigmented fungus in this list is Candida albicans.
