(2016) and our own observations, the asexual morph of the genus Microdochium is characterized as follows. The mycelium is immersed, branched, and septate, with hyphae ranging from hyaline to pale brown. Sporodochia, when present, are located within or beneath the host epidermis. They emerge through stomata, by rupturing the outer epidermal wall and cuticle, or via specialized egression hyphae that penetrate the outer epidermal wall. The sporodochia are hyaline, composed of pseudoparenchyma, and expand after emerging from the host tissue. Conidiophores are more or less verticillate and often reduced to conidiogenous cells. Conidiogenous cells are holoblastic and discrete, occurring singly or aggregated in small sporodochia; they may exhibit sympodial proliferation (cylindrical to clavate, with apical denticles) or percurrent / annellidic proliferation (subcylindrical to lageniform). Conidia are dry, or in slimy masses, unicellular to multiseptate, hyaline and smooth; their shapes include lunate, falcate, fusiform, filiform, obovoid or subpyriform, straight or curved, with rounded apex and flattened base. Chlamydospores are terminal or intercalary, brown, and may be solitary, in chains, or clustered. The sexual morph is Monographella - like, characterized by perithecial ascomata with a papillate ostiole, unitunicate asci with an amyloid apical ring, and clavate to fusoid ascospores (see Hernández-Restrepo et al. 2016).</p><p>Notes.</p><p>The genus Microdochium was introduced with M. phragmitis as its type species, isolated from Phragmites australis in Germany. The genus is characterized by hyaline conidiogenous cells and conidia that are highly variable in shape, ranging from cylindrical, fusoid, or oblong to lunate, straight or curved, with truncate bases and apices rounded (Sydow 1924; Hernández-Restrepo et al. 2016). Recently, Zhang et al. (2024) proposed the genus Macroidriella, typified by Macroidriella bambusae, based on its lunate and curved conidia. However, the conidial morphology of Microdochium is known to include lunate and curved forms (Sydow 1924; Hernández-Restrepo et al. 2016). Therefore, the lunate and curved conidia alone do not justify the establishment of Macroidriella as a distinct genus. Based on phylogenetic analyses, divergence time estimation, and morphological comparisons, we formally propose to synonymize Macroidriella Z. X. Zhang, J. W. Xia &amp; X. G. Zhang under Microdochium Syd. Consequently, the type species Macroidriella bambusae is transferred to Microdochium as a new name below.</p></div>	https://treatment.plazi.org/id/8ED6FABD107E5153BEA95E06E164C53E	Public Domain	No known copyright restrictions apply.

Conidiogenous cells terminal, monoblastic, cylindrical, 25.17–54.47 × 2.65–3.27 μm (av. = 41.57 ± 14.69 × 2.97 ± 0.31 μm, n = 13). Conidia dry, reniform, fusiform, straight, smooth with thin walls, hyaline, 10.67–14.15 × 3.51–4.32 μm (av. = 11.84 ± 1.31 × 3.90 ± 0.33 μm, n = 16). Chlamydospores not observed. Sexual morphs unknown, see Fig. 16.</p><p>Culture characteristics.</p><p>Colonies on PDA. 70.20–73.58 mm in diameter after 7 d at 25 ° C in darkness, with a growth rate of 10.03–10.51 mm / day, entire at edge, gray in obverse and fawn reverse.</p><p>Additional specimen examined.</p><p>CHINA • Guangdong Province, Guangzhou City, Conghua District, on leaves of Bambusa vulgaris, 01 March 2025, Y. X. Shang (HSAUP 17227-1 A), living culture SAUCC 17227-1 A .</p><p>Notes.</p><p>Nucleotide base pair comparisons across two gene regions (rpb 2 and tub 2) between M. vulgaris and M. bambusicola (SAUCC 7623-2) species revealed differences of 29 / 841 bp and 12 / 702 bp. Nucleotide base pair comparisons across two gene regions (rpb 2 and tub 2) between M. vulgaris and M. bambusae (SAUCC 1862-1) species revealed differences of 36 / 841 bp and 18 / 689 bp. In morphology, these species are distinguished by the length of conidiogenous cells in M. vulgaris, M. bambusicola, and M. bambusae (25.17–54.47 × 2.65–3.27 μm vs. 6.85–7.66 × 1.32–2.02 μm vs. 17.4–30.0 × 2.5–3.0 µm), and by their distinct conidial dimensions (10.67–14.15 × 3.51–4.32 μm vs. 6.28–11.12 × 2.85–4.11 μm vs. 13.0–17.0 × 2.5–3.5 µm) (Zhang et al. 2023 a). Therefore, based on morphology and phylogenetic evidence, we establish this fungus as Microdochium vulgaris sp. nov.</p></div>	https://treatment.plazi.org/id/B49FE1CA38E05D969605FD82EAE4DEE8	Public Domain	No known copyright restrictions apply.
