Ulocladium is a widely distributed mould commonly found in soil and decaying plants. It has also been isolated from paper, textiles, dung, emulsion paint, grasses, fibres and wood. In indoor environment, Ulocladium has been found on painted surfaces, damp wall finished with wallpaper or water based emulsion paint; floor and mattress dust.
Ulocladium has two known species; Ulocladium chartarum and Ulocladium botrytis. Ulocladium chartarum is the species most commonly found in indoor environment. Presence of Ulocladium in indoor environment together with other moulds such as Stachybotrys, Fusarium and Chaetomium is an indication of water damage.
Ulocladium has been reported to cause Type I (hay fever) allergy. There have been cases of Ulocladium chartarum causing skin surface and deep skin infections in immuno-suppressed patients. Ulocladium botrytis has no proven pathogenicity.
