The taxonomic history of anamorphic species attributed to Penicillium subgenus Biverticillium was reviewed along with evidence supporting their relationship with teleomorphic species classified in Talaromyces by Samson et al. (2011). To supplement previous conclusions based on ITS, SSU and/or LSU sequencing that Talaromyces and subgenus Biverticillium comprise a monophyletic group that is distinct from Penicillium at the generic level, the phylogenetic relationships of these two groups with other genera ofTrichocomaceae was further studied by sequencing a part of the RPB1 (RNA polymerase II largest subunit) gene. Talaromyces species and most species of Penicillium subgenus Biverticillium sensu Pitt reside in a monophyletic clade distant from species of other subgenera of Penicillium. For detailed phylogenetic analysis of species relationships, the ITS region (incl. 5.8S nrDNA) was sequenced for the available type strains and/or representative isolates of Talaromyces and related biverticillate anamorphic species. Extrolite profiles were compiled for all type strains and many supplementary cultures. All evidence supported their conclusions that Penicillium subgenus Biverticillium is distinct from other subgenera in Penicillium and should be taxonomically unified with the Talaromyces species that reside in the same clade.

Following the concepts of nomenclatural priority and single name nomenclature, all accepted species of Penicillium subgenus Biverticillium were transferred to Talaromyces. A holomorphic generic diagnosis for the expanded concept of Talaromyces, including teleomorph and anamorph characters, see Samson et al. (2011).

Species of biotechnological and medical importance, such as P. funiculosum and P. marneffei, are now combined in Talaromyces.
