Description:

See Suppl. material 1: table S1.

Materials examined.

Taiwan, Yilan County, Yuanshan Township , on stroma of Ophiocordyceps sp. parasitic on an insect ( Lepidoptera ), 15 June 2018, Wei-Yu Chuang, living culture NTUPPMCC 18-160 (= CD01) . Taiwan, Taichung City, Heping District, Yuanzui Mountain , on stroma of Ophiocordyceps sp. parasitic on an ootheca ( Mantodea ), 14 July 2021, Ming-Syun Wu, living culture NTUPPMCC 21-055 (= CD10) .

Notes.

The two new strains NTUPPMCC 18-160 and NTUPPMCC 21-055, used in the present study, clustered within a clade containing ex-type strains of four Pestalotiopsis taxa, namely P. kenyana (CBS 442.67), P. oryzae (CBS 353.69), P. rhodomyrtus (HGUP 4230) and P. trachycarpicola (IFRDCC 2440) in both single- and multi-locus phylogenies with poor statistical support and short branch lengths. Furthermore, a comparison of the morphological features of these four species and the two strains used in the present study revealed overlapping characteristics, as shown in Suppl. material 1: table S9. However, two strains, included in the present study, tentatively named as P. trachycarpicola ( Zhang et al. 2012) giving the priority for the oldest species name amongst these four Pestalotiopsis species. Nevertheless, further studies of P. trachycarpicola (IFRDCC 2440), P. rhodomyrtus (HGUP 4230), P. oryzae (CBS 353.69) and P. kenyana (CBS 442.67) are essential to determine whether these species belong to a single population or if the few informative loci used in the present and previous studies ( Liu et al. 2017; Tsai et al. 2021) lead to the poorly-resolved phylogram.
