Sexual morph Undetermined. Asexual morph Hyphomycetous, helicosporous. Colonies on natural substrate superficial, effuse, gregarious, yellowish green to brown. Mycelium partly immersed, partly superficial, composed of pale brown to brown, branched, septate, guttulate, smooth hyphae. Conidiophores 132–144 × 3.7–4.8 μm (x ̄ = 139 × 5.5 μm, n = 30), macronematous, mononematous, erect, cylindrical, long, straight or slightly flexuous, simple, septate, brown to dark brown at base, paler towards the apex, smooth, thick-walled. Conidiogenous cells 4.5–10 × 3–4.4 μm (x ̄ = 8 × 3.6 μm, n = 30), holoblastic, monoblastic, or polyblastic, integrated, intercalary, cylindrical, denticulate, arising laterally from the lower portion of conidiophores as tiny bladder-like protrusions (3–4 µm long, 2–2.7 µm wide), with each bearing 1–2 tiny sporogenous conidiogenous loci, hyaline to pale brown, smooth. Conidia solitary, pleurogenous, helicoid, tapering towards the rounded ends, developing on bladder-like protrusion, 11.7–12 μm in diameter, and conidial filament 1.2–2.1 μm wide (x ̄ = 11.9 × 1.7 μm, n = 30), 72.5–84 μm long (x ̄ = 76.5 μm, n = 35), up to 4 1 / 2 times, becoming loosely coiled when the conidia are young and not becoming loose when mature in water, indistinctly multi-septate, guttules, hyaline, smooth-walled.</p><p>Culture characteristics.</p><p>Conidia germinating on PDA within 11 hours, producing germ tubes from the conidial body.

However, nucleotide polymorphisms in the ITS, LSU, tef 1 - α, and rpb 2 sequence data between GZCC 25–0641 and H. hainanense (GZCC 22–2006) revealed nucleotide differences of 11 / 432 bp (2.5 %, with no gaps), 5 / 814 bp (0.6 %, with no gaps), 11 / 906 bp (1.2 %, with no gaps), and 39 / 1,045 bp (3.7 %, with no gaps), respectively. Furthermore, Helicosporium qixianlingense (GZAAS 25–0671) differs from H. hainanense (GZAAS 22–2006, ex-type) by its longer conidia (72.5–84 μm vs. 55–60 μm), narrower conidial filament (1.2–2.1 μm vs. 2–3 μm), and more coiled times (up to 4 1 / 2 times vs. 2 1 / 4 –2 3 / 4 μm times) (Lu et al. 2022 a). Therefore, based on both molecular and morphological evidence, we introduce Helicosporium qixianlingense as a novel species.</p></div>	https://treatment.plazi.org/id/95DDAD3A530059F8A508C0298E766624	Public Domain	No known copyright restrictions apply.

Peridium composed of several layers of brown to dark brown cells of textura angularis, outer layer brown cells, and inner layer pale brown to hyaline cells.

However, H. tongrenense (HKAS 128925) differs from H. flavum (MFLU 17–0704) by shorter ascospores (37–48 μm vs. up to 60 μm) (Brahmanage et al. 2017). Additionally, H. flavum possesses short, setae-like projections, which are absent in H. tongrenense (Brahmanage et al. 2017). Phylogenetically, our isolates (GZCC 23–0026 and GZCC 25–0640) form a sister clade to H. jiangkouense (HKAS 128933), with 100 % MLBS and 1.00 BYPP support. However, comparison of the ITS, LSU, tef 1 - α, and rpb 2 sequence data between H. tongrenense (GZCC 23–0026) and H. jiangkouense (HKAS 128933) revealed nucleotide base differences of 26 / 526 bp (4.9 %, including 1 gap), 51 / 834 bp (6.1 %, including 3 gaps), 1 / 884 bp (0.1 %, including 1 gap), and 1 / 916 bp (0.1 %, with no gaps), respectively. Notably, the asexual morph of H. jiangkouense is the only form observed to date (Ma et al. 2024 b). Therefore, based on both multigene phylogenetic analyses and morphological differences, we introduce Helicosporium tongrenense as a novel species.</p></div>	https://treatment.plazi.org/id/77504171AE715F29BC9D47EDBB4A5ED0	Public Domain	No known copyright restrictions apply.
