R. Xiong, Manawas. & K. D. Hyde 2025	<div><p>Neodeightonia guineensis Y.R. Xiong, Manawas. &amp; K.D. Hyde, sp. nov. (Fig. 2)</p><p>Index Fungorum number: IF903050, Facesoffungi number: FoF 16988</p><p>Etymology:— Epithet refers to the host species from which the fungus was isolated.</p><p>Holotype:— MHKU 24-0149</p><p>Saprobic on petiole of Elaeis guineensis ( Arecaceae). Sexual morph: Ascomata 150–180 × 210–290 µm (x = 160 × 240 µm; n = 10), semi-immersed, solitary, gregarious, unilocular, raising host surface and producing papillate black dots of dehiscence. Peridium 15–55 μm wide (x = 30 µm; n = 20), thick-walled, brown-black cells of textura angularis, smooth, asci developing amongst partially disintegrating sterile thin-walled tissue in locule. Hamathecium 3–6.5 μm wide (x = 4.5 µm, n = 30), pseudoparaphyses, gelatinized, pluricellular, hyaline, constricted at the septa. Asci 80–165 × 20–35 µm (x = 110 × 30 µm; n = 20), bitunicate with a thick endotunica, fissitunicate, separated from one another by stromatic tissue, clavate, 8-spored, with a minute club pedicel. Ascospores 28–32 × 13–15 µm (x = 30 × 14 µm; n = 30), biseriate, hyaline to pale brown, ellipsoidal, muriform when mature, aseptate, rough, surrounded by a tightly fitting mucilaginous sheath. Asexual morph: not observed.</p><p>Culture characters:— colonies on PDA reaching 7 cm diam., at 28 ˚ C after five days. Upper view wrinkled, filamentous, entire margin, flat, cloudy, fluffy for aerial hyphae, becoming grey-black with age, dense aerial hyphae, reverse becoming black.</p><p>Material examined:— CHINA. Yunnan Province: Xishuangbanna City, in an unidentified forest beside National Highway 219 (21°93'N, 101°24E, 549.6 m), on rotting petiole of Elaeis guineensis, 5 February 2023, Y. R. Xiong and Li Lu, XG 180 (MHZU 24-0149, holotype) ; ex-type, ZHKUCC 24-0105, other living culture ZHKUCC 24-0106 .</p><p>Notes:— Two isolates from this study formed a well-separated lineage with 93% ML, 99% MP and 0.99 BIPP support within Neodeightonia species, clustering with N. palmicola . The nucleotide differences excluding gaps of ITS between N. guineensis (ZHKUCC 24-0105) and N. palmicola (MFLUCC 10-0822) is 3.65% (19/521 base pairs). Neodeightonia guineensis is a sexual morph and differs from N. palmicola, which has slightly larger asci (154.2 × 20.5 µm) and smaller ascospores (27 × 10 µm) (Liu et al. 2010). In addition, N. palmicola has ascospores with bipolar germ pores (Liu et al. 2010), whereas they are absent in N. guineensis . Moreover, N. palmicola has ascospores surrounded by a thick complex sheath (Liu et al. 2010), while N. guineensis is surrounded by a thin, tightly fitting mucilaginous sheath. Based on the phylogenetic placement and morphological variations, we introduce N. guineensis as a novel Neodeightonia species.</p></div>	https://treatment.plazi.org/id/4C4D87CFFF9693044EDAFB743CE5FE89	Public Domain	No known copyright restrictions apply.
