This image depicts a front view of a Petri dish culture plate, which had contained an unidentified growth medium that had been inoculated with the fungal organism, Hortaea werneckii, also known as Cladosporium werneckii, and which subsequently produced this ruffled, velvety gray fungal colony, and viewed here after a 4-week growth period. Colonies of the fungus H. werneckii are slow growing, initially mucoid, yeast-like, and shiny black at maturity. This fungus is the causative agent of tinea nigra, a superficial skin infection affecting the stratum corneum in humans.
