A comparison of nucleotides between K. guizhouensis (GZCC 24-0034) and K. acutisporum showed similarity rates in the ITS 77 % (407 / 528 bp, 36 gaps), LSU 93 % (785 / 847 bp, 13 gaps), and SSU 96 % (818 / 849 bp, 2 gaps), indicating significant differences between the two species. Morphologically, our species exhibits distinct characteristics compared to K. acutisporum, including smaller conidia with a mucilaginous sheath (36.5–65 × 8–16.5 µm vs. 75–120 × 10.5–19.5 μm), and longer conidiophores which are branched at the apex (195–477 × 11–16 μm vs. 180–260 × 7–12.5 μm) (Jayawardena et al. 2022). Therefore, we propose K. guizhouensis as a new species.</p></div>	https://treatment.plazi.org/id/FF3ABDC93EDA5C508A14659E4D7344DF	Public Domain	No known copyright restrictions apply.

Kirschsteiniothelia weiningensis and K. cangshanensis are both sporidesmium-like taxa and share highly similar characteristics, which render their differentiation based solely on morphology a challenge. This is a common occurrence among many sporidesmium-like taxa (Su et al. 2016). Nevertheless, ITS comparison reveals that K. weiningensis (GZCC 24-0072) exhibits 92 % identity (684 / 740, 14 gaps) and 93 % identity (474 / 502, 2 gaps) to K. cangshanensis (MFLUCC 16-1350) and Kirschsteiniothelia sp.
