Summary Species of the P seudallescheria boydii / S cedosporium apiospermum complex ( PSC ) are emerging fungal pathogens able to chronically colonize the airways of patients with cystic fibrosis ( CF ). As P . boydii was found more frequently colonizing the lungs of CF patients in F rance than in other E uropean countries in a previous report, the present study was conducted in order to clarify distribution of PSC species in France and to characterize their natural habitat. The highest densities of PSC isolates were found in human‐impacted areas, i.e . agricultural areas, fluids obtained from wastewater treatment plants, playgrounds and industrial areas. PSC was not detected from soil samples collected in forests. Most PSC culture‐positive soil samples exhibited a pH range of 6–8. S cedosporium dehoogii , the most abundant species, was detected in all human‐impacted area types except vineyards, whereas S cedosporium aurantiacum was mostly found in agricultural areas. P seudallescheria boydii and S . apiospermum were predominantly isolated from seashores and playgrounds respectively. P seudallescheria minutispora was found only once from a playground. This study highlights potential sources of contamination of the patients, especially in the CF context.
