description: <i>Mucispora hydei</i> Wijayaw., Q.R. Li, Y.C. Deng, L.S. Dissan &amp; D-Q Dai <i>sp. nov.</i> (FIGURE 1) <i>Index Fungorum number</i>: IF558463 <b>Etymology:—</b> Named in honour of British mycologist, K.D. Hyde for his immense contributions to mycology Holotype:— GMB0028 <i>Saprobic</i> on decaying wood. <b>Asexual morph</b> Hyphomycetous. <i>Conidiophores</i> 60–110 × 8–12 µm (x̅ = 78.6 × 9.8 µm, n = 30), macronematous, mononematous, erect, solitary or in small groups on compactly aggregated cells, simple, cylindrical, smooth, brown, straight or slightly flexuous, percurrently proliferate 2–3 times, 1–2-septate. <i>Conidiogenous cells</i> holoblastic, integrated, terminal, cylindrical, smooth, pale brown. <i>Conidia</i> 35-50 × 20-30 µm (x̅ = 41.2 × 25.5 µm, n = 30), acrogenous, solitary, simple, smooth, ellipsoidal to obovoid, hyaline to subhyaline when young, dark brown when mature, with obvious septa in young conidia, paler at basal cell, truncate at base, sometimes covered by a hyaline mucilaginous sheath. <b>Sexual morph</b> Undetermined. <b>Material examined:—</b> CHINA, Guizhou Province, Guiyang, Gaopo Township, Raorao village (106°48’6.54”E, 26°19’3.46”N), on decaying submerged wood, 9 th December 2019, Nalin N. Wijayawardene, Q. R Li, (GMB0028, <b>holotype</b>, NNW56, <b>isotype</b>). LSU: MW797122, SSU MW 800164, ITS MW 797039 (Supplementary Table 1) <b>Known distribution</b>:— Guizhou Province, China <b>Notes</b>:— Yang <i>et al.</i> (2016) introduced the genus <i>Mucispora</i> Jing Yang <i>et al.</i> with <i>M. obscuriseptata</i> J. Yang <i>et al.</i> as the type species. Besides the type species, the genus comprises two species <i>viz</i>. <i>M. phangngaensis</i> J. Yang &amp; K.D. Hyde (Yang <i>et al.</i> 2017) and <i>M. infundibulata</i> J. Yang &amp; K.D. Hyde (Hyde <i>et al.</i> 2020). All these species have been reported from submerged plant materials in Southern Thailand (Prachuap Khiri Khan Province and Phang Nga Province). In morphology, <i>Mucispora</i> closely resembles <i>Melanocephala</i> but it is specific in its cupulate proliferating conidiogenous cells and its conidia bearing a central downwardly directed collar with a fimbriate margin’ (Hughes 1979; Yang <i>et al.</i> 2017). Our new collection did not germinate in different media (WA, PDA, MEA) and in different temperatures thus we extracted DNA directly from the fruiting body (Zeng <i>et al.</i> 2018). PCR amplification of ITS (ITS 4/ ITS 5), LSU (primers: LR5/ LROR) and SSU (primers: NS 1/ NS 4) were successful. Phylogenetic analyses of combined LSU and ITS genes (Fig. 2) that our new strain is distinct from other taxa. However, the separation value is medium (69% in ML) and PP value is low. Nevertheless, morphological characters, of our collection is well-distinct from other <i>Mucispora</i> species (Table 2). Hence, we introduce the fourth species of the genus, <i>Mucispora hydei</i>. This is the first record of the genus outside Thailand.
