Chlamydospores and microconidia were absent. Sexual morph: — Unknown. Culture characteristics: — Colonies diameters after one week at 25 ° C on PDA, OA, and PCA were 76 – 79, 75 – 78, and 72 – 75 mm, respectively. Colonies on PDA were greyish yellow, with sparse white aerial mycelia, velvety, circular, flat, margin slightly irregular and fimbriate; reverse olive grey. Colonies on OA were greyish yellow, with sparse white aerial mycelia, velvety, circular, flat, margin slightly irregular and fimbriate, olivaceous gray at center; reverse olive grey. Colonies on PCA were olivaceous gray to greenish grey with sparse gray aerial mycelia, circular, flat, margin slightly irregular and fimbriate; reverse greenish grey. Sporulation was observed on all three media after one week. Cardinal temperature for growth: — Optimum 25 ° C, maximum 37 ° C, minimum 10 ° C.	en	Lapmak, Kodchakorn, Kumla, Jaturong, Phookung, Kotcharat, Suwannarach, Nakarin (2025): Curvularia nelumbonicola (Pleosporaceae, Pleosporales), a new endophytic fungus from Thailand.

BB0287D5CE20FFC7FF553CDBFCB522F3.taxon	discussion	Note: — Phylogenetically, C. nelumbonicola forms a monophyletic clade that is sister to type strains of C. chonburiensis (MFUCC 16 - 0375), C. hominis (UTHSC 09 - 464), C. muehlenbeckiae (CBS 144.63), C. platzii (BRIP 27703 b), C. pisi (CBS 190.48), and C. plantarum (CGMCC 3.19342), and C. lycopersici strain 11 with 79 % BS and 0.96 PP support values. (Figure 1). Morphologically, the 2 – 3 - distoseptate conidia of C. nelumbonicola differ from those of C. hominis (4 – 5 - distoseptate), C. muehlenbeckiae (4 - distoseptate), and C. plantarum (4 - distoseptate), and C. platzii (9 – 13 - distoseptate) (Madrid et al. 2014, Tan et al. 2018, Raza et al. 2019) (Table 3). Curvularia nelumbonicola resembles C. chonburiensis and C. pisi in having 2 – 3 - distoseptate conidia. However, the shorter conidiophores in C. nelumbonicola (10 – 60 μm long) distinguish it from C. chonburiensis (70 – 200 μm long) (Tibpromma et al. 2018) and C. pisi (50 – 210 μm long) (Marin-Felix et al. 2017). There is currently limited information on the morphological description of C. lycopersici. A pairwise nucleotide comparison of GAPDH sequences shows that C. nelumbonicola differs from C. chonburiensis, C. hominis, C. muehlenbeckiae, C. platzii, C. pisi, and C. plantarum by 2.12 %, 3.59 %, 3.92 %, 5.39 %, 4.08 %, and 3.10 %, respectively (Table 4).	en	Lapmak, Kodchakorn, Kumla, Jaturong, Phookung, Kotcharat, Suwannarach, Nakarin (2025): Curvularia nelumbonicola (Pleosporaceae, Pleosporales), a new endophytic fungus from Thailand.
