Etymology: Cladosporium is a genus name, coined in 1816 by the German mycologist Johann Heinrich Friedrich Link, who was building a classification of fungi from the Greek roots "klados" (branch) and "sporos" (seed or spore). The name describes the fungus's typical form: spores borne on branching chains of conidiophores, which give colonies their characteristic dark, velvety look. Because the genus is named for its branching spore-bearing structures, the word refers to a whole group of organisms rather than one species. Cladosporium species are among the most widespread fungi on Earth, found on living plants, dead plant matter, textiles, and damp building surfaces, where they appear as the dark green or black patches people call mold.
