It is widespread in the environment and can be found in composts, soils and wood, as well es a common environmental contaminant in indoor air and carpet dust. Ascospores of the sexual state of P. variotii (B. spectabilis) are strongly heat-resistant. As such the fungus is a common contaminant of heat-treated foods and juices. Paecilomyces variotii has been associated with a number of infective diseases of humans and animals.
