Comparisons of nucleotide sequences between N. coffeae and N. edgeworthiae revealed minor overall differences; however, the ITS region showed a 14 / 550 bp (2.54 %, 5 gaps) difference. Morphologically, the conidiogenous cells of our isolates are notably longer than those of N. edgeworthiae (13.2–20.6 μm vs. 9–14 μm) (Ma et al. 2024 b). Conversely, the conidia of our collections are significantly smaller than those of N. edgeworthus, both in diameter (13.5–19.4 μm vs. 21.5–34 μm) and length (105.3–146.4 μm vs. 121–177 μm) (Ma et al. 2024 b). In addition, the conidia of N. edgeworthiae are aseptate and have numerous guttulate, whereas conidia of our collections are multi-septate, lack guttulate, and have only surface granules (Ma et al. 2024 b). In summary, although the nucleotide divergence between our collections and N. edgeworthiae is relatively low, the combination of distinct morphological characters and phylogenetic position supports their separation, and therefore, we introduce N. coffeae herein as a novel species.</p></div>	https://treatment.plazi.org/id/0051396CB4DB54B697054258973BBA0A	Public Domain	No known copyright restrictions apply.

Sequence comparisons between N. coffeae and N. dehongensis revealed greater divergence in the ITS region (34 / 933 bp; 3.6 %, no gap). Morphologically, our species resembles N. dehongensis in having macronematous and mononematous conidiophores, holoblastic conidiogenous cells with denticles, and helicoid, multi-septate, hyaline conidia (Dong et al. 2020). However, it differs from N. dehongensis in having slightly shorter conidiophores (138.8–211.7 µm vs. 120–250 µm) and conidia (106.6–211.2 µm vs. 145–210 µm), as well as narrower conidial diameters (15.2–22 µm vs. 20–25 µm) (Dong et al. 2020). In addition, conidia of N. puerensis are distinctly multi-septate, whereas those of N. dehongensis are indistinctly septate. The conidial filaments in our collections are more tightly coiled (2.5–4.25 times vs. 2.75–3.75 times), and conidiophores are usually unbranched, lacking the basal forking that is frequently observed in N. dehongensis . Moreover, conidiogenous cells of N. puerensis are terminal or intercalary, whereas those of N. dehongensis are mostly intercalary and sympodial. Thus, based on these morphological differences and molecular evidence, we propose that N. puerensis be recognized as a new species.</p></div>	https://treatment.plazi.org/id/BFC4DBB2726956E39D0DEF7CAA1DF804	Public Domain	No known copyright restrictions apply.
