Purpureocillium takamizusanense (Kobayasi) S.Ban, Azuma & Hirok.
Sato, 2015
a number of unclassified isolates.

P. lilacinum was previously considered to be monotypic and was classified with the Fungi Imperfecti or Deuteromycetes, fungi for which perfect (i.e., sexually reproducing) states have rarely been found. "
Paecilomyces lilacinus" was classified in the section Isarioidea, for which perfect states had not been found.
Many isolates of P. lilacinum have been identified from around the world and it is accepted that variation exists within the species.
Phylogenetic analysis of P. lilacinum isolates show that it is not related to Trichoderma, Gliocladium and Hypocrea and more related to entomopathogenic genera such as Hirsutella and Ophiocordyceps in the Hypocreales.
