Asexual morph: Colonies superficial, effuse, hairy, velvety, brown to black, scattered. Mycelium partly superficial, partly immersed, consisting of branched, septate, smooth, smooth-walled, hyaline to pale brown hyphae. Conidiophores 105–230 × 5–7.3 μm (x ̄ = 160.7 × 6 μm, n = 25), macronematous, mononematous, solitary, erect, unbranched, septate, straight or flexuous, cylindrical, slightly constricted at septa, brown, becoming subhyaline to pale brown towards the apex. Conidiogenous cells 7.2–13 × 2.7–4.2 μm (x ̄ = 9.5 × 3.4 μm, n = 30), mono- or polyblastic, integrated, terminal or intercalary, occasionally bearing bladder-like conidiogenous loci at the subapical, 5–5.5 × 2.1–2.4 μm, cylindrical, subhyaline to brown. Conidia 15.4–20.4 × 9.2–12.2 μm (x ̄ = 17.7 × 10 μm, n = 30), acropleurogenous, pyriform, obovoid to broadly ovoid, 1 - septate, guttulate, subhyaline to brown, slightly constricted at the septa, with a subhyaline remain of the conidiogenous cell and small basal protrusion at the base of the conidia, smooth-walled. Sexual morph: Undetermined.</p><p>Culture characteristics.</p><p>Conidia germinated on PDA within 13 h, producing germ tubes from the conidial body. Colonies on PDA were irregular with a flat surface and an undulate margin, reaching 31 mm in diameter after 34 days at room temperature (approximately 25 ° C). Colony coloration was pale brown to black on both the surface and reverse sides.</p><p>Material examined.</p><p>China • Guizhou Province, Tongren City, Yinjiang Tujia and Miao Autonomous County, on dead branches of Polygonatum, 23 March 2025, Xiao-Fang Chen, Xiang-Yu Zhang &amp; Tao Zhou, HJ 10 (GZAAS 25-0779, holotype), ex-type living culture GZCC 25-27588 ; • ibid., HJ 6 (GZAAS 25-0780, paratype), living culture GZCC 25-27589 .</p><p>Notes.</p><p>In the phylogenetic tree (Fig. 1), the isolates (GZCC 25-27588 and GZCC 25-27589) formed a distinct sister clade to Kramasamuha sibika (CBS 146133 and COAD: 2632) and Kramasamuha sp. (XG 276 a), although this relationship is supported by unstable bootstrap support. Comparative analyses of LSU sequences revealed that the collection (GZCC 25-27588) differs from K. sibika (CBS 146133) by 58 out of 827 bp (7 %, including three gaps). In addition, GZCC 25-27588 differs from Kramasamuha sp. (XG 276 a) by 56 out of 871 bp (6.4 %, including three gaps). Morphologically, Obovatispora polygonati (GZAAS 25-0660) can be readily distinguished from Kramasamuha sibika by its conidiogenous cells, which are single and bladder-like to cylindrical, whereas those of K. sibika are mostly arranged in clusters of 2–4 and are lageniform to almost cylindrical (Subramanian and Vittal 1973). Obovatispora polygonati possesses predominantly cylindrical conidiogenous cells, sometimes with tiny bladder-like conidiogenous loci, whereas those of K. sibika are ampulliform and curved or taper nearly to a point at the apex (Subramanian and Vittal 1973; Bispo et al. 2024). Therefore, based on multigene phylogenetic evidence combined with its distinct morphological characteristics, O. polygonati is designated as a novel species within the genus Obovatispora .</p></div>	https://treatment.plazi.org/id/73FB2F5A81D6504387EE3212F62E7E21	Public Domain	No known copyright restrictions apply.
