Mycol. 12 (4): 417 (1914)</p><p>Notes.</p><p>Dendryphiella, a dematiaceous hyphomycete genus, was proposed by Ranojevic (1914) and typified by D. interseminata, which is currently considered a synonym of D. vinosa based on morphology (Reisinger 1968). The anamorph is characterized by macronematous, septate, and pigmented conidiophores with terminal or intercalary polytretic conidiogenous cells that are enlarged at the apex, with dark scarring on the nodose swellings, producing acropleurogenous, solitary or catenate conidia, which are commonly multi-septate and cylindrical with rounded ends (Ellis 1971; Du et al. 2025). Currently, no Dendryphiella species have been linked with their teleomorph (Liu et al. 2017). In this study, a new species of Dendryphiella, collected from the submerged, decaying stem of Nelumbo nucifera in freshwater in Jiangxi Province, is introduced.</p></div>	https://treatment.plazi.org/id/0A613F6827EE5121A3FA741E8CD02C64	Public Domain	No known copyright restrictions apply.

The sequence similarity between the two strains (JAUCC 8231 and JAUCC 8232) is above 99 % for the analyzed genes, confirming their conspecificity. The BLASTn searches of ITS, LSU, and TEF 1 - α sequences showed 89 %, 99 %, and 97 % similarity to D. eucalyptorum (PP 925612, MN 999929, and PP 926518, respectively), and the SSU sequence shows 99 % similarity to D. phitsanulokensis (NG _ 065729). Morphologically, D. loti aligns with the general descriptions of the genus Dendryphiella by having polytretic and integrated conidiogenous cells with septate, catenate conidia (Hyde et al. 2018; Du et al. 2025). Dendryphiella loti (HFJAU 10951, holotype) can be distinguished from other Dendryphiella species by conidiophores swollen at the nodules and 1–3 - septate and smooth-walled conidia with thickened and darkened scars (Fig. 2), while other species exhibit polytretic conidiophores, and the conidia have a verrucose surface texture (Hyde et al. 2018; Du et al. 2025). Therefore, D. loti is introduced as a new species, the second species of this genus reported from aquatic habitats.</p></div>	https://treatment.plazi.org/id/568E4DCAC6AE53CA8C3A6494C0C64AA0	Public Domain	No known copyright restrictions apply.

Most genera in Dictyosporiaceae are hyphomycetous, although a few possess coelomycetous morphs (Barr 1987 a, 1987 b; Tanaka et al. 2015; Lu et al. 2025), and the teleomorphs have so far been confirmed only in five genera: Dictyosporium, Gregarithecium, Immotthia, Pseudocoleophoma, and Verrucoccum (Barr 1987 a, 1987 b; Tanaka et al. 2015; Lu et al. 2025). Members of Dictyosporiaceae are widely distributed worldwide and occur mainly on decaying plant litter and woody substrates in both terrestrial and aquatic habitats; their pathogenicity has not yet been confirmed (Hongsanan et al. 2020; Boonmee et al. 2021; Shen et al. 2022 b). Over the past two decades, extensive sampling combined with molecular analyses has led to a rapid increase in the number of genera and species recognized within Dictyosporiaceae (Boonmee and D’souza 2016; Phookamsak et al. 2019; Shen et al. 2022 b). Currently, the family comprises 23 accepted genera and approximately 178 species (Lu et al. 2025; Wang et al. 2025 a).</p></div>	https://treatment.plazi.org/id/3F543F632A4E52279F695565B59EA094	Public Domain	No known copyright restrictions apply.

Most taxa in this family are rare, occurring as small clusters or isolated individuals on diverse substrates, such as decaying wood, sphagnum moss, or old basidiomata. In addition, many species do not grow in culture, which has severely limited the availability of molecular data (Miller et al. 2014). This has hindered the phylogenetic resolution of the group, leaving many genus-level classifications unsupported or poorly defined, which has resulted in the prevalence of polyphyletic or paraphyletic groupings within the family. LSU and TUB 2 markers provide good suprageneric resolution (Miller et al. 2014; Yang et al. 2023; Lu et al. 2025). Morphologically, most taxa are characterized by ascomata with distinct thick-walled setae, a key diagnostic feature for identification (Miller et al. 2014). Notably, the placement of Selenosporella curvispora in this family has been confirmed (Réblová et al. 2021), and the Selenosporella phenotype is widespread among its members. The family encompasses diverse modes of conidiogenesis, including tretic ( Diplococcium), holoblastic ( Endophragmiella), and holoblastic-denticulate ( Selenosporella and Selenosporella - like). For instance, Helminthosphaeria has a Diplococcium anamorph, some forming Selenosporella - like synanamorphs, while Endophragmiella dimorphospora, Echinosphaeria canescens, Hilberina punctata, and Ruzenia spermoides are also linked to Selenosporella - like synanamorphs (Miller et al. 2014; Réblová et al. 2021). To date, the family comprises six genera: Echinosphaeria, Helminthosphaeria, Hilberina, Kramasamuha, Ruzenia, and Selenosporella (Hyde et al. 2024) .</p></div>	https://treatment.plazi.org/id/D95DF54F1F7C58CA99534F2B5BCD517E	Public Domain	No known copyright restrictions apply.

Morphologically, H. jiangxiensis aligns with the general descriptions of the genus Hilberina, such as brown to dark brown and superficial ascomata and septate-lumen setae (Miller et al. 2014; Yang et al. 2023). Hilberina jiangxiensis exhibits fusiform conidia (19–25 × 4.5–7 µm), distinct from the oval and smaller conidia observed in H. hongheensis (13–16 × 6–9 μm) (Yang et al. 2023; Fig. 5). In addition, morphological comparisons were made with species for which molecular data were unavailable (viz., H. breviseta, H. elegans, H. foliicola, H. moseri, H. meznaensis, and H. rhynchospora). Hilberina jiangxiensis can be distinguished by fusiform ascospores with distinct granules, while other species have cylindrical ascospores, with a basal end that is attenuate and acerose (Miller et al. 2014). Therefore, H. jiangxiensis is introduced as a new species in Hilberina . Furthermore, this is the first time that species of this genus have been reported from aquatic habitats.</p></div>	https://treatment.plazi.org/id/7845406E16F15A419F17F68B41DD58BE	Public Domain	No known copyright restrictions apply.

Subsequently, phylogenetic analysis showed that Dictyosporella, Junewangia, and Sporidesmiella clustered within Junewangiaceae (Dong et al. 2021; Hyde et al. 2023). Additionally, Jennwenomyces was proposed to replace Belemnospora navicularis with Jennwenomyces navicularis, which was described and illustrated based on two specimens collected from decaying culms submerged in freshwater streams (Goh and Kuo 2020). Although phylogenetic analysis placed Jennwenomyces within Junewangiaceae, Goh and Kuo (2020) classified it as a genus in Sordariomycetes, incertae sedis. There are currently four accepted genera in Junewangiaceae that occur primarily as saprobes on a variety of plant debris in terrestrial and freshwater habitats (Hyde et al. 2024). However, the phylogenetic boundaries between Dictyosporella, Junewangia, Jennwenomyces, and Sporidesmiella remain unclear (Goh and Kuo 2020; Hyde et al. 2023), but they exhibit distinct morphological differences (Wang et al. 2025 a).

Among them, N. mali was isolated from herbivore dung and plant leaves of Malus domestica in Spain and Italy, respectively, while the other two were isolated from soil in Mexico and Spain (Iturrieta-González et al. 2018). Later, Neodendryphiella tarraconensis was re-isolated from decaying wood from China (Guizhou Province) (Hyde et al. 2020 c). Subsequently, N. agapanthi (isolated from stalks of Agapanthus praecox, Brazil-Minas Gerais) and N. brassaiopsidis (recovered from dead stems of Brassaiopsis hainla, China, Yunnan Province) were introduced as new species based on molecular phylogeny and morphological characters (Dong et al. 2023; Crous et al. 2025). To date, only five species of Neodendryphiella have been listed in Index Fungorum (2026). Neodendryphiella is characterized by polytretic, integrated conidiogenous cells that produce acropetal, branched chains of conidia (Iturrieta-González et al. 2018). In this study, a new species of Neodendryphiella, collected from the submerged, decaying stem of Nelumbo nucifera in freshwater in Jiangxi Province, is introduced.</p></div>	https://treatment.plazi.org/id/E17BA6C570DB503792EA8227D93AA098	Public Domain	No known copyright restrictions apply.

The BLASTn search of the ITS sequence shows 99 % similarity with N. michoacanensis (LT 906660), and the LSU sequence shows 98 % similarity with N. tarraconensis (PQ 671127). Members of Neodendryphiella only have the ITS and LSU genes available in GenBank. Morphologically, N. loti aligns with the general descriptions of Neodendryphiella, such as polytretic conidiogenous cells that form conidia in acropetal, branched chains (Iturrieta-González et al. 2018). However, N. loti (HFJAU 10952, holotype) can be distinguished from other Neodendryphiella species by the light brown and smooth-walled conidia, with dense central contents, while other species have verruculose to verrucose conidia, with scars thickened and darkened (Iturrieta-González et al. 2018; Dong et al. 2023; Crous et al. 2025; Fig. 3). Neodendryphiella loti can be morphologically distinguished from N. michoacanensis by the smaller conidiogenous cells (18–22 × 4–5 μm vs. 11–62 × 3–5 μm) and conidia (10-14 × 4-6 μm vs. 16–18 × 3–6 μm); the conidia of N. loti have thickened and darkened scars, are 1 - septate, and are smooth-walled with dense central contents, whereas N. michoacanensis conidia are verruculose to verrucose and 1 (– 2) - septate (Iturrieta-González et al. 2018; Fig. 3). Therefore, N. loti is introduced as a new species in Neodendryphiella .

In addition, Pleurothecium aquaticum produces clavate, hyaline, 3 - septate, whitish to grayish conidia (18–22 × 4–5 μm) (Luo et al. 2018), and P. guttulatum produces clavate, 3–4 - septate, hyaline conidia (22–28 × 5–6 μm) (Shi et al. 2021); however, P. saprophyticum has elliptical to obovoid, hyaline, 3 - septate conidia (14–21.5 × 4.5–6.5 μm) (Fig. 18). Based on pairwise nucleotide comparisons, P. saprophyticum (JAUCC 7170, ex-type) diverges from P. aquaticum (MFLUCC 17-1331, ex-type) by 18 / 532 bp (3.3 %, without gaps) for ITS and 5 / 813 bp (0.5 %, without gaps) for LSU; it also diverges from P. guttulatum (KUMCC 20-0152, ex-type) by 13 / 524 bp (2.4 %, without gaps) for ITS and 5 / 811 bp (0.6 %, without gaps) for LSU. Therefore, Pleurothecium saprophyticum is considered a new species within the genus Pleurothecium .</p></div>	https://treatment.plazi.org/id/68E04E40BEE950F7991FE8654DBAF5D1	Public Domain	No known copyright restrictions apply.

Morphologically, the features of the strain are almost the same as those of the holotype X. oblongispora but exhibit newly observed characters: ellipsoidal to subglobose conidia that are hyaline to light brown, while the holotype has oblong conidia with obtuse ends and is hyaline (Lin et al. 2025; Fig. 21).
