A comparison of LSU, ITS, tef 1 - α, and rpb 2 sequences between the ex-type strain of  N. guizhouense (GZCC 23-0078) and  N. wuzhishanense (GZCC 23-0326) revealed 2 / 837 bp (0.2 %, including one gap), 26 / 773 bp (3.4 %, including one gap), 21 / 885 bp (2.4 %, without a gap), and 35 / 914 bp (3.8 %, including one gap) nucleotide base differences, respectively, which strongly support them as two distinct species. Morphologically,  Neohelicosporium guizhouense (HKAS 128908) differs from  N. wuzhishanense (HKAS 128903) by its distinct conidiogenous cells (tooth-like vs. tooth-like and / or bladder-like), smaller conidial filaments (3.5–5 μm vs. 4.5–6 μm), and different coiled states in water (loosely coiled vs. tightly coiled). Therefore, we designate the three isolates (GZCC 23-0023, GZCC 23-0078, and GZCC 23-0545) as a new species,  Neohelicosporium guizhouense .</p></div>	https://treatment.plazi.org/id/BBAA5E13348B51878619BBD3E357F368	Public Domain	No known copyright restrictions apply.

However, based on multi-gene phylogenetic analyses,  Neohelicosporium wuzhishanense formed a sister clade with  N. guizhouense, which is phylogenetically distant from  N. latisporum (Fig. 1). Morphologically,  Neohelicosporium wuzhishanense (HKAS 128903) differs from  N. latisporum (HKAS 128955) by its unique conidiogenous cells (tooth-like and / or bladder-like vs. tooth-like) and longer conidia (92.5–138 μm vs. 48.5–67.5) (Ma et al. 2024 b). Based on morphological characteristics and DNA sequence data, we identified GZCC 23-0278, GZCC 23-0279, and GZCC 23-0326 as a new species,  Neohelicosporium wuzhishanense .</p></div>	https://treatment.plazi.org/id/5A9891C37491537FAA99390117570EC5	Public Domain	No known copyright restrictions apply.
