Ulocladium is reported to be a major type I allergen. This saprobe (weak parasite) is widespread and commonly found on plant materials, soils, dung, grass, compost, and textiles. Some species are cellulolytic and can grow on water-damaged building materials. Ulocladium is also found in dust and air samples; and indoors on carpets and painted surfaces. This mitosporic (lacks a sexual state) fungus has been reported from cases of phaeohyphomycosis (cutaneous and subcutaneous infections caused by dematiaceous (dark-walled) fungi). Infection sites for susceptible hosts vary widely. Conidia are dark brown to black, egg-shaped to cylindrical, solitary, smooth or rough, divided into several cells by transverse, longitudinal walls. The colonies are moderately fast growing, wooly to cottony or velvety, olive-brown to black or grayish in color. (A_w - 0.89).
