Maximum likelihood (ML) phylogenetic tree based on a concatenated dataset of ITS, cmdA, rpb2, and tub2. Species representing section Talaromyces including 113 strains representing 98 taxa were included in the concatenated dataset, with 2127 characters (ITS 536 bp, cmdA 336 bp, rpb2 843 bp, and tub2 412 bp) including alignment gaps. The tree was rooted with Talaromyces helicus CBS 335.48 (Section Helici). MLB ≥ 70% and BPPs ≥ 0.95 were shown at each node; values lower than these thresholds are indicated by a hyphen (–). The scale bar indicates the number of estimated substitutions per site. The strains introduced in this study are in red and novel species are in bold. The ex-type strains are marked with T.
