Morphologically, Periconia guangxiense (GZAAS 25-0735, holotype) can be easily distinguished from P. variicolor (CBS 120374) by micronematous, branched conidiophores, while P. variicolor has macronematous and unbranched conidiophores. Periconia guangxiense also has a smaller size range of conidia (6–7.5 µm vs. 7.5–9.5 μm) than the holotype of P. variicolor (CBS 120374) (Cantrell et al. 2007). In addition, pairwise nucleotide comparisons showed that ITS of Periconia guangxiense (GZCC 25-0705) differed 40 / 508 bp (7.87 %, with gaps) from that of P. variicolor (SACCR- 64), which strongly supports our strains as a new species. The PHI test revealed no significant recombination event between our strains (GZAAS 25-0735 and GZAAS 25-0733) and the closely related taxa. The significant recombination between our two strains indicates that they are conspecific (Φw = 0.98) (Fig. 4). Therefore, Periconia guangxiense is introduced as a distinct new species of Periconia .</p></div>	https://treatment.plazi.org/id/91B757BB54105275830F12D1E8E5639D	Public Domain	No known copyright restrictions apply.
