Pairwise nucleotide comparisons revealed that the new isolate GZCC 25-27619 is similar to HKAS 105122 in 479 / 486 bp (99 %) of the ITS region, 764 / 764 bp (100 %) of the LSU region, and 883 / 883 bp (100 %) of the LSU 1 - αα region. Morphologically, our isolate is consistent with the holotype HKAS 10-5122 of Neohelicomyces astrictus in key diagnostic features, including helicoid, hyaline conidia and similar conidiogenous cell (Lin et al. 2025). However, it differs in having longer conidiophores (50–350 μm vs. 22–161 μm) and somewhat longer conidia (90–170 μm vs. 100–136.5 μm). Despite these minor differences, the overall morphology and phylogenetic placement support its identification as N. astrictus . Notably, our specimen was collected from a freshwater habitat, whereas HKAS 10-5122 was reported from a terrestrial habitat (Lin et al. 2025), representing a new habitat record for this species.</p></div>	https://treatment.plazi.org/id/95EFD75A009E56AF8A89DCD02DD7439B	Public Domain	No known copyright restrictions apply.

Pairwise nucleotide comparisons revealed that N. brevis (GZCC 25-27621, ex-type) and N. qixingyaensis (CGMCC 3.25569, ex-type) shared 402 / 424 bp (95 %) similarity in the ITS region, 787 / 788 bp (99 %) in the LSU region, 915 / 948 bp (97 %) in the rpb 2 region, and 853 / 855 bp (98 %) in the LSU 1 - α region, excluding gaps. Morphologically, N. qixingyaensis (HKAS 128928, holotype) possesses developed macronematous, mononematous conidiophores (94.5–187 × 3.5–6 μm), monoblastic or polyblastic, integrated conidiogenous cells with denticles (7–18 × 3–5.5 μm), and helicoid, aseptate conidia that do not become loose in water (98–147 μm × 1.5–3 μm) (Ma et al. 2024 b). In contrast, our new isolate has micronematous conidiophores and produces conidia that become loosely coiled in water, are septate, and are longer than N. qixingyaensis (113–186 × 2–4 µm vs. 98–147 μm × 1.5–3 μm) (Ma et al. 2024 b). The two species differ ecologically, with N. brevis being saprobic in freshwater habitats, whereas N. qixingyaensis occurs in terrestrial habitats (Ma et al. 2024 b). Based on both molecular and morphological evidence, the new species Neohelicomyces brevis is herein proposed.</p></div>	https://treatment.plazi.org/id/E53EBDCFEECC5394A53064CE8FE467F5	Public Domain	No known copyright restrictions apply.
