Cladosporium sp

Colonies are rather slow growing, mostly olivaceous-brown to blackish brown but also sometimes grey, buff or brown, suede-like to floccose, often becoming powdery due to the production of abundant conidia. Vegetative hyphae, conidiophores and conidia are equally pigmented. Conidiophores are more or less distinct from the vegetative hyphae, are erect, straight or flexuous, unbranched or branched only in the apical region, with geniculate sympodial elongation in some species

Cladosporium species have a world-wide distribution and are amongst the most common of air-borne fungi. Some 500 species have been described. Isolates of Cladosporium are frequently isolated as contaminants.
