The genus Purpureocillium was introduced by Luangsa-ard et al. (2011) with P. lilacinum as the type species, and has been reported as an important human pathogen. Apart from the type species, Purpureocillium comprises three species viz P. atypicola, P. lavendulum and P. takamizusanense (Index Fungorum 2019). The type, Paecilomyces lilacinus is a ubiquitous, saprobic filamentous fungus often isolated from soil, decaying vegetation, insects, nematodes and laboratory air (as contaminant), and is a cause of infection in man and other vertebrates (Perdomo et al. 2013, Quandt et al. 2014). In addition, it also can colonize material such as catheters and plastic implants and can contaminate antiseptic creams and lotions (Castro et al. 1990, Orth et al. 1996, Itin et al. 1998).

Type species: Purpureocillium lilacinum (Thom) Luangsa-ard, Houbraken, Hywel-Jones & Samson, FEMS Microbiol. Lett. 321(2): 144 (2011).
