BLASTn comparisons further support its phylogenetic distinction. The ITS sequence shows highest similarity to D. phangngaensis MFLUCC 16-0857 (99.15 %). However, protein-coding loci reveal lower similarity values: RPB 2 shows 96.88 % similarity to D. nanpingensis (HJAUP C 2517) and TEF 1 - α shows 94.69 % similarity to D. jinghongensis (HJAUP C 2120). Pairwise nucleotide comparisons further support the recognition of Distoseptispora antiqueana as a distinct species, differing from D. phangngaensis by 0.34 % (2 / 588 bp, ITS) and 7.56 % (73 / 965 bp, TEF 1 - α) sequence divergence. The introduction of Distoseptispora antiqueana, as with all novel taxa described in this study, follows the integrative species delimitation approach of Jeewon and Hyde (2016), whereby species are recognised, based on concordant phylogenetic evidence, nucleotide differences across informative loci and diagnostic morphological characters. Distoseptispora antiqueana differs from D. phangngaensis by having shorter, but wider conidiophores (12–35 × 7–11 μm vs. 18–30 (– 40) × 4.3–6.5 μm), shorter and narrower conidia (139–268 × 9–16 μm vs. 165–350 × 14–19 μm) (Yang et al. 2018). The observed interspecific divergence in the protein-coding genes, together with its independent phylogenetic position and morphological differences support its designation as a distinct species.</p><p>This represents the second confirmed record of Distoseptispora from a marine habitat, isolated from submerged decaying wood in a mangrove ecosystem; the first such record is D. mangrovei reported from China (Li et al. 2026). Members of the genus are predominantly reported from freshwater and terrestrial environments; thus, this finding expands the known ecological range of the genus into marine-associated substrates (Calabon et al. 2022; Ma et al. 2022; Hu et al. 2023; Shen et al. 2024; Liao et al. 2025).</p></div>	https://treatment.plazi.org/id/173CA2E3D5CA5BDB946199AF85DEAF6F	Public Domain	No known copyright restrictions apply.

Both taxa conform to the generic circumscription of Distoseptispora in producing holoblastic, monoblastic, acrogenous conidiogenous cells and distoseptate, obclavate to rostrate conidia. Morphologically, the two species are readily separable by conidial dimensions and septation patterns. Distoseptispora daanyuanensis is characterised by exceptionally long and highly septate conidia (23.1–696.2 × 9.3–17.9 μm; 4–92 distosepta), representing the broadest range in both size and septation (Liu et al. 2025). In contrast, D. iloiloensis is distinguished by comparatively smaller conidia ((82 –) 102–200 (– 385) × 6–19 μm) with up to 39 distosepta, generally lacking apical percurrent regeneration. Pairwise nucleotide comparisons further support their distinction wherein D. iloiloensis differs from D. daanyuanensis by 1.40 % (8 / 573 bp, ITS), 1.78 % (15 / 843 bp, LSU) and 0.78 % (7 / 892 bp, TEF 1 - α) sequence divergence. Ecologically, the taxa occupy discrete substrates: D. daanyuanensis is reported from decaying wood in peat swamp forest and D. iloiloensis from submerged wood in freshwater habitat (Liu et al. 2025). This ecological segregation, coupled with subtle, yet stable morphological differences, suggests niche specialisation within this phylogenetically cohesive lineage.</p></div>	https://treatment.plazi.org/id/ABDCD0B9A0DA5E67B3E166F816F81099	Public Domain	No known copyright restrictions apply.

Pairwise nucleotide comparisons further substantiate its distinction: D. panayensis differs from D. amniculi by 2.9 % (16 / 551 bp, ITS) and 0.8 % (7 / 875 bp, LSU) and 7.53 % (80 / 1063 bp, TEF 1 - α). Morphologically, D. panayensis is characterised by relatively long and moderately broad conidiophores (66–134 × 4–8 μm, x ¯ = 111.7 × 5.2 μm) that are 6–10 - septate and occasionally show percurrent elongation. It differs from D. amniculi, which possesses longer, but distinctly narrower conidiophores (90–180 × 3–4.5 μm) (Yang et al. 2021). Distoseptispora panayensis produces conspicuously long, obclavate-rostrate conidia (82–174 × 7–12 μm, x ¯ = 117.8 × 9.4 μm) with 13–23 distosepta and overlapping, but generally surpassing that of D. amniculi ((7 –) 12–24 - septate; 85–167 × 9–11.8 μm). Ecologically, D. panayensis and D. amniculi are freshwater taxa occurring on submerged decaying wood (Yang et al. 2021). Pairwise nucleotide comparisons between D. panayensis and D. jinghongensis revealed sequence differences of 4.84 % (29 / 599 bp) in the ITS region, 3.97 % (23 / 579 bp) in LSU and 7.38 % (71 / 962 bp) in TEF 1 - α. Morphologically, D. panayensis differs by having longer and wider conidiophores (66–134 × 4–8 μm vs. 54.6–94.6 × 3.6–4 μm), more septate conidiophores (6–10 vs. 4–7 septa) and considerably longer conidia (82–174 × 7–12 μm vs. 56.4–127.3 × 7.3–10.9 μm) with a greater number of distosepta (13–23 vs. 7–17) (Hu et al. 2023). Furthermore, D. jinghongensis was observed on dead branches of an unidentified broadleaf tree. The consistent morphological and multi-locus phylogenetic distinctions support the establishment of D. panayensis as a novel species.</p></div>	https://treatment.plazi.org/id/CCB84D1C4774537199F2929C30BFA1B2	Public Domain	No known copyright restrictions apply.

(2022) from submerged decaying wood in a freshwater stream in China. Both strains, GZCC 22-0078 (holotype) and UPVMICC 25–0088, were collected as saprobes on submerged woody substrates in freshwater habitats and conform well to the generic circumscription of Distoseptispora . Distoseptispora septata GZCC 22-0078 possesses longer conidiophores (23–86 μm, up to 6 - septate) and comparatively shorter conidia (22–179 × 10–16 μm, mean 89 × 13 μm) with up to 25 distosepta and reportedly verrucose conidial walls (Ma et al. 2022). In contrast, UPVMICC 25–0088 is characterised by shorter conidiophores (≤ 20 μm, 2–3 - septate) and markedly longer conidia (129–220 × 9–15 μm, mean 159.5 × 12.4 μm) bearing up to 46 distosepta. Phylogenetically, UPVMICC 25–0088 clusters with the holotype strain GZCC 22–0078 with maximal statistical support (100 % MLBS, 1.00 BYPP). Nucleotide comparisons reveal no differences in the ITS and RPB 2 loci, while minor variation is observed in LSU (3 / 821 bp; 0.37 %) and TEF 1 - α (2 / 915 bp; 0.22 %). Although differences were observed in conidiophore and conidial dimensions, species delimitation in Distoseptispora is based on the integration of morphological characteristics and multilocus phylogenetic evidence and morphological variation amongst conspecific collections has been documented within the genus (Hyde et al. 2020; Yang et al. 2021). Therefore, the strong phylogenetic support and low sequence divergence across multiple loci confirm that UPVMICC 25–0088 and GZCC 22–0078 represent conspecific isolates of D. septata, with the observed morphological differences falling within the species’ phenotypic range. This study represents a new geographic record of D. septata .</p></div>	https://treatment.plazi.org/id/622AC26CE53C5C0C839CD1451913B006	Public Domain	No known copyright restrictions apply.
