Talaromyces section Tenues B.D. Sun, A.J. Chen, Houbraken & Samson   sect. nov.

Typus.

Talaromyces tenuis   B.D. Sun, A.J. Chen, Houbraken & Samson

Description.

Conidiophores monoverticillate or biverticillate, with hyaline, thin stipes, colonies grow restrictedly on CYA, YES, DG18, slightly faster on MEA and OA, no growth on CYAS and CREA at 25 °C and CYA incubated at 37 °C.

Phylogenetic analysis places Talaromyces section Tenues   sister to sections Talaromyces   and Helici   (Fig. 1 View Figure 1 ); however, statistical support for this relationship is lacking. Using a nine-gene sequence data set, Houbraken et al. (2020) confidently shows that Talaromyces   sp. CBS 141840 (= T. tenuis   , the sole representative of the section) is sister to sect. Purpurei   and Trachyspermi   . section Trachyspermi   species produce abundant red pigments ( Yilmaz et al. 2014), while Talaromyces tenuis   does not. section Purpurei   species generally grow rapidly on CYA and MEA, and usually produce synnemata after two to three weeks of incubation ( Yilmaz et al. 2014).

Etymology.

Named after the type species of the section, Talaromyces tenuis   .
