According to the multi-gene phylogenetic analysis (Fig. 1), our isolates formed a distinct clade, sister to  Neoroussoella leucaenae, which was previously reported from decaying pods of  Leucaena sp. and  Pterocarpus sp. in Thailand (Jayasiri et al. 2019). This relationship is supported by statistical values of 79 % MLBS and 0.78 BIPP (Fig. 1). On PDA, colonies of  N. guizhouensis display a light gray center surrounded by a white ring, distinguishing it from  N. solani, which exhibits white to lavender-gray colonies and produces rosy buff to grayish-rose pigments (Mochizuki et al. 2017). Morphological data for  N. leucaenae and  N. entadae on PDA are unavailable in the literature. However, on MEA,  N. leucaenae shows gray to brown hyphal growth with a radially arranged brown edge and a two-layered reverse side, dark brown and brown. In contrast,  N. entadae displays irregular edges with a thin, light-colored outer layer embedded in the medium, a three-layered reverse side of dark brown with distinct boundaries, and scattered pycnidia throughout the culture medium (Jayasiri et al. 2019). Phylogenetically, the new species was grouped with  N. guizhouensis,  N. leucaenae,  N. solani, and  N. entadae . However, the morphological distinctions are evident among those species, particularly in the conidiogenous cells. Although all species exhibit bottle-shaped sporogenic structures,  N. leucaenae is characterized by flask- to cylindrical-shaped cells with a thicker neck and nearly round base. In contrast,  N. guizhouensis has a narrow-necked bottle shape, whereas  N. solani shows a broader base, with some cells appearing nearly oval.  N. entadae displays phialidic, ampulliform to cylindrical conidiogenous cells. The dimensions of the conidiogenous cells differ significantly among the species:  N. guizhouensis (9–35 × 1–6 µm),  N. leucaenae (5.5–9 × 3–4 µm),  N. solani (5–10 × 3.5–5 µm), and  N. entadae (3.5–5.6 × 0.7–1.8 µm). Conidia size comparisons also highlight differences:  N. guizhouensis (2.9–4 × 2–2.6 µm),  N. leucaenae (3.5–4.5 × 1.9–2.6 µm),  N. solani (3.9–5.3 × 1.9–2.2 µm), and  N. entadae (3–4 × 1.7–1.9 µm). While  N. guizhouensis and  N. leucaenae are similar in spore size, they have shorter lengths and narrower widths compared to  N. solani and exhibit similar lengths but narrower widths compared to  N. entadae . Additionally, nucleotide sequence comparisons of the ef 1 - α and rpb 2 loci revealed differences between  N. guizhouensis (GUCC 24-0197) and  N. leucaenae (MFLUCC 17-0927), with 2 - bp and 16 - bp discrepancies, respectively. Based on these findings,  N. guizhouensis is established as a new species.</p></div>	https://treatment.plazi.org/id/C7A0504FD6C15C0684C0347B53F54518	Public Domain	No known copyright restrictions apply.

This species was initially reported from dead stems of  Chromolaena odorata in Thailand, with its sexual morph documented by Mapook et al. (2020). Subsequently, Ryu et al.

In the current study, sequence data from the ITS, LSU, ef 1 - α, and rpb 2 loci of newly isolated strains were identical to those of  X. triseptata, confirming their conspecific status. The morphological characteristics of the asexual morph of the new strains were consistent with those previously described by Ryu et al. (2022) based on observations from the PDA medium. Conidiogenous cells were ampulliform to doliiform, producing unicellular conidia. Conidia were globose to ellipsoid with a blunt apex containing one or two guttules. The conidia contained one or two guttules, measuring 2.7–5.1 × 1.6–3.3 µm (Ryu et al. 2022).
