In morphology, they are distinguished by different hosts ( Phragmites australis vs. Miscanthus sinensis), and M. australiana colonies on PDA exhibit a prominent, milky white aerial mycelium bulge, with a central pale orange region and a grayish edge. In contrast, M. miscanthi colonies are overall white, featuring a central dark-green plaque covered by white mycelia. Mycelial width (2.2–2.9 µm) in M. australiana vs. (1.5–2.3 µm) in M. miscanthi . Conidia in M. australiana differ from those in M. miscanthi (cylindrical, ampulliform vs. transparent, spindle-to-rod-shaped) (Liu et al. 2022). Therefore, we establish this fungus as M. australiana sp. nov.</p></div>	https://treatment.plazi.org/id/FF4ABEE253715BAE83B2AD0EF7E34723	Public Domain	No known copyright restrictions apply.

Specifically, the center of M. baishamenense colonies is milky white, with lush mycelia; the mycelia at the edge are sparse and pale brown, and the colony reverse is light yellow. In contrast, M. fisheri (CBS 242.90) exhibits a salmon-colored center, a peach-colored periphery, and an entire margin. M. baishamenense produced cylindrical, clavate to obovoid conidia, whereas M. fisheri (CBS 242.90) has conidia that are tarry, dry, fusiform, obovoid, or subpyriform, and there are 155 distinct nucleotide positions separating the species (14 / 527 in ITS, 13 / 830 in LSU, 34 / 687 in tub 2, 94 / 839 in rpb 2) (Hernández-Restrepo et al. 2016).</p></div>	https://treatment.plazi.org/id/8497FBBE06665FC38DA543409241E5E1	Public Domain	No known copyright restrictions apply.

In morphology, they are distinguished by different hosts (Bambusoideae sp. vs. Paspalum sp.). The two species exhibit significant morphological divergence. M. bambusina produces conidia measuring 4.8–7.2 × 2.1–3.4 μm, which are significantly larger than those of M. gongcheniae (3.3–6.4 × 0.8–2.3 μm), and M. bambusina colonies on PDA are gray white with regular margins. M. gongcheniae colonies on PDA are orange with flocculent mycelia, and subtle differences are observed in the shapes of conidia: M. bambusina conidia are ellipsoid, spindle-to-rod-shaped, whereas M. gongcheniae exhibits reniform to fusiform conidia (Yan and Zhang 2024).
