This study aims to determine the occurrence of Pseudallescheria and Scedosporium species in natural and human-dominated environments. Habitats (136 sampling sites) in a transect with increasing human impact were investigated (natural areas, agricultural soils, urban playgrounds, industrial areas). Physico-chemical parameters were measured to characterize the different areas included in this investigation. Fungal identification was performed by morphology and sequence data analysis. Comparative description of virulence was largely based on the database of the ECMM/ISHAM Working Group on Pseudallescheria/Scedosporium Infections. Pseudallescheria and Scedosporium species were most abundant in industrial areas, followed by urban playgrounds and agricultural areas. None of the species were isolated from natural habitats. The abundance of Pseudallescheria and Scedosporium species could be correlated with increasing nitrogen concentrations (P
