description: <i>Moelleriella puerensis</i> H. Yu, Z. Q. Wang &amp; Y. Wang, <i>sp. nov.</i> <b>Etymology:—</b> Named after Puer City, where the species was first collected. <b>Holotype:—</b> CHINA. Yunnan Province, Puer City, Simao District, Xinfang Reservoir (N22°28’12”, E 100°57’12”), alt. 1371 m, on whiteflies on abaxial surface of leaves, 7 October 2019, <i>H. Yu</i> (YHH10001, holotype; YFCC 8615, ex-holotype culture); <i>Ibid.</i>, (YHH 10002, paratype; YFCC 8625, ex-paratype living culture); <i>Ibid.</i>, (YHH 10003, paratype; YFCC 8625 ex-paratype living culture). <b>Sexual morph:—</b> <i>Stromata</i> generally effuse to thin pulvinate with pronounced ovoid tubercles on periphery of stroma, pale yellow, 1.5–3.6 mm in diameter, opaque. <i>Hyphae</i> loose textura intricata to epidermoidea. <i>Perithecia</i> 280–520 × 425–600 µm, fully embedded, ostioles orange, numerous perithecia (&gt;10) per stroma, subglobose to ovoid. <i>Asci</i> 130–285 × 6.0–12.5 µm, cylindrical, hyaline. <i>Apical cap</i> hemispherical, 3.5–5.0 × 6.0–8.5 µm. <i>Ascospores</i> as long as asci, hyaline, filiform, multi-septate, smooth, disarticulating into secondary spores. <i>Secondary spores</i> 7.9–13 × 2.3–3.5 µm, fusiform with rounded ends. <b>Asexual morph:—</b> Sexual and asexual morph usually existing in the same stroma, exclusively anamorphic stromata pulvinate with sloping sides (convex), pale yellow to orange. <i>Conidiomata</i> aggregated in center of stroma, simple depressions of the surface without distinct rims, several conidiomata per stroma, fusing with neighboring ones, widely open. Conidial masses orange. In section, conidioma flask-shaped or irregular, shallow, 150–180 × 130–170 µm, with phialides formed in a thick compact palisade. <i>Phialides</i> 9–30 × 1–2 µm, cylindrical, slightly tapering towards tip, <i>Conidia</i> 9.7–13.4 × 1.3–2.3 µm hyaline, smooth, one-celled, fusoid, with acute ends, Paraphyses present. Colonies on PDA at 25°C slow-growing, tomentose, compact, pale yellow. <i>Conidial</i> masses circularly arranged towards center of colonies, abundant, confluent and deep orange. <i>Conidia</i> 11.2–17 × 2.1–3.1 µm. <i>Paraphyses</i> absent. <i>Hirsutella</i> -like synanamorph is present. <i>Phialides</i> 8.5–48.6 × 0.5–1.5 µm, flask-shaped, with a long neck 5.6–41.5 µm long. <b>Known distribution:—</b> Puer City, Yunnan Province, China. <b>Notes:—</b> <i>Moelleriella puerensis</i> was similar to <i>M. raciborskii.</i> However, the teleomorph of <i>M. puerensis</i> differed from <i>M. raciborskii</i> in having longer asci and shorter secondary spores (Liu <i>et al</i>. 2006). The anamorph of <i>M. puerensis</i> differed from <i>M. raciborskii</i> by having shorter conidia; the conidia formed in PDA was wider than <i>M. raciborskii</i> (Liu <i>et al</i>. 2006).
