This genus is very similar to Rhinocladiella, however the conidia are typically two-celled. Occasional skin infections have been reported from humans (Revankar and Sutton 2010).
Colonies grow rapidly and are suede-like to downy, greyish-brown to blackish-brown. Conidiophores are erect, straight or flexuose, occasionally branched and are usually geniculate, due to the sympodial development of the conidia. They are smooth-walled, pale to medium olivaceous-brown, up to 250 µm long and 2-4 µm wide. Conidia are pale brown, two-celled, cylindrical with a truncated base, smooth-walled or slightly verrucose, 5-12 x 3-4 µm.
