Similar topologies were also observed in single-gene tree phylogenies with high support values (Suppl. material 2: figs S 1 – S 3). Brunswickiella nypae (MFLU 25-0393) is different based on ITS and RPB 2 loci from B. parsonsiae (CBS 137979), not including gaps, by nucleotide substitutions: 6 / 517 (1.15 %) in ITS and 64 / 964 (6.64 %) in RPB 2. Morphological comparisons revealed that our species produced a different type of conidiomata (Fig. 6) compared to B. parsonsiae (CBS 137979) (Crous et al. 2014; Videira et al. 2017), as detailed in Table 1. Brunswickiella nypae produces larger conidia than B. parsonsiae (Crous et al. 2014) . Brunswickiella parsonsiae was isolated from leaves of Parsonsia straminea ( Apocynaceae) in Australia (Crous et al. 2014), while our species was isolated from leaf spots of Nypa fruticans in Thailand. Thus, based on morphological differences, host association, nucleotide differences, and molecular phylogenetic analyses, we introduce Brunswickiella nypae as a new species.</p></div>	https://treatment.plazi.org/id/64671CE3FAE75974B85D80F1E9DC0E94	Public Domain	No known copyright restrictions apply.

In addition, P. dracaenicola (MFLUCC 18-0913, MFLUCC 18-0914) was grouped within the same clade with our species and P. dracaenae (Fig. 2). A similar topology was also observed in the TUB 2 - gene tree phylogeny (Suppl. material 2: figs S 4 – S 6). Pestalotiopsis nypae (MFLU 25-0396) is different based on ITS, TEF 1 α, and TUB 2 loci from P. dracaenae (HGUP 4037), not including gaps, by nucleotide substitutions: 4 / 523 (0.78 %) in ITS, 5 / 407 (1.23 %) in TEF 1 α, and 10 / 391 (2.56 %) in TUB 2. It is different from P. dracaenicola (MFLUCC 18-0913), 4 / 523 (0.76 %) in ITS, 6 / 405 (1.48 %) in TEF 1 α, and 8 / 409 (1.96 %) in TUB 2. The PHI test indicated no significant recombination between P. nypae and its closely related species: P. dracaenae and P. dracaenicola (Fig. 5). Morphological comparisons revealed differences in conidial and appendage dimensions, as detailed in Table 2. Pestalotiopsis nypae produces smaller conidia and a larger l / w ratio than P. dracaenae (Ariyawansa et al. 2015) and P. dracaenicola (Chaiwan et al. 2020) . Pestalotiopsis nypae produces longer apical appendages than P. dracaenae and P. dracaenicola, whereas the basal appendage of P. nypae is slightly longer (Fig. 7) than P. dracaenae and P. dracaenicola (Ariyawansa et al. 2015; Chaiwan et al. 2020). Pestalotiopsis dracaenae was isolated as an endophyte from leaves of Dracaena fragrans ( Asparagaceae) in China (Ariyawansa et al. 2015); P. dracaenicola is saprobic on dead leaves of Dracaena sp. ( Asparagaceae) in Thailand (Chaiwan et al. 2020), while our species was isolated in association with leaf spots of Nypa fruticans ( Arecaceae) in Thailand. Thus, based on morphological differences, phylogenetic analyses, nucleotide differences, the PHI test, and host association, we introduce Pestalotiopsis nypae as a new species.</p></div>	https://treatment.plazi.org/id/9E9B3F500BA9542BBA82E5C70163F0E6	Public Domain	No known copyright restrictions apply.

Pestalotiopsis jiangmenensis was introduced by Wang et al. (2025) from diseased needles of Pinus massoniana in China. Zhang et al. (2026) synonymized P. pyrrosiae-linguae with P. spatholobi using polyphasic methods, but P. jiangmenensis was not included in the analysis as this species was recently introduced. Morphologically, P. jiangmenensis, P. pyrrosiae - linguae, and P. spatholobi have nearly overlapping phenotypic characteristics. Thus, based on our phylogenetic analyses and the synonymies proposed by Zhang et al. (2026), P. jiangmenensis is proposed as a synonym of P. spatholobi .</p></div>	https://treatment.plazi.org/id/A5BE837F6D05578C95D73D3ABE83F8F9	Public Domain	No known copyright restrictions apply.
