Morphological and molecular identification of four new resupinate species of Lyomyces (Hymenochaetales) from southern China

Abstract

Four new wood-inhabiting fungal species, Lyomyces bambusinus, L. cremeus, L. macrosporus and L. wuliangshanensis, are proposed based on a combination of morphological and molecular evidence. Lyomyces bambusinus is characterized by resupinate basidiomata with colliculose to tuberculate hymenial surface and broadly ellipsoid, hyaline, slightly thick-walled, smooth basidiospores. Lyomyces cremeus is characterised by resupinate basidiomata with smooth, cream hymenial surface and ellipsoid, hyaline, thin-walled to slightly thick-walled basidiospores. Lyomyces macrosporus is characterized by pruinose basidiomata with reticulate hymenial surface, presence of three kinds of cystidia and larger basidiospores (6.7-8.9 × 4.4-5.4 µm). Lyomyces wuliangshanensis is characterized by coriaceous basidiomata and ellipsoid, hyaline, slightly thick-walled, smooth basidiospores. The phylogenetic analyses based on molecular data of the internal transcribed spacer (ITS) region sequences revealed that the four new species belonged to Lyomyces. Lyomyces bambusinus grouped with L. sambuci. Lyomyces cremeus clade was sister to a clade comprised of L. microfasciculatus. Lyomyces macrosporus was sister to L. allantosporus. Lyomyces wuliangshanensis was closely related to L. mascarensis. A peer-reviewed open-access journal MycoKeys Launched to accelerate biodiversity research RESEARCH ARTICLE

Five new species of Schizoporaceae (Basidiomycota, Hymenochaetales) from East Asia

“…Many recently described wood-inhabiting fungal taxa have been reported in the subtropics and tropics, including in the genera Lyomyces and Xylodon (Xiong et al 2009;Chen et al 2017;Kan et al 2017a, b;Riebesehl and Langer 2017;Viner et al 2018;Chen and Zhao 2020;Luo et al 2021a, b, c;Luo et al 2022;Viner et al 2022) (Xiong et al 2009;Riebesehl and Langer 2017;Chen and Zhao 2020;Luo et al 2021b, c;Wang et al 2021). The present study reports five new species in Lyomyces and Xylodon, based on a combination of morphological features and molecular evidence.…”

Diversity of Wood-Decaying Fungi in Wuliangshan Area, Yunnan Province, P.R. China

“…Although some remarkable explorations of wood-decaying fungi have been made from the Yunnan Province [57,68,[79][80][81][82][83][84][85][86][87][88][89], only nine new species, Rhomboidia wuliangshanensis, Gloeodontia yunnanensis, Lyomyces bambusinus, L. cremeus, L. macrosporus, L. wuliangshanensis, Peniophorella fissurata, Perenniporia mopanshanensis and Serpula dendrocalami were found from the Wuliangshan area [85,86,[90][91][92][93]. Species in the present list are mostly new to the studied area.…”

Morphological and phylogenetic characterization of fungi within Hymenochaetales: introducing two new species from southern China

“…sambuci , L. tenuissimus (Yurchenko & Sheng H. Wu) Riebesehl & Langer and L. wuliangshanensis C.L. Zhao (Xiong et al 2009, Yurchenko and Wu 2013, Yurchenko et al 2013, Riebesehl and Langer 2017, Chen and Zhao 2020). Based on our morphology and phylogeny studies, all of these can be separated from the two new species (Fig.…”

“…Species of Lyomyces are found on dead, still‐attached or fallen branches of angiosperms, on dead wooden or herbaceous stems, or occasionally on gymnosperm wood (Yurchenko et al 2017). Worldwide, thirty‐eight Lyomyces species are currently known (Karsten 1881, 1882, 1884, 1889, Bourdot and Galzin 1991, Cunningham 1959, 1963, Wu 1990, Hjortstam and Ryvarden 2009, Xiong et al 2009, Yurchenko and Wu 2013, Yurchenko et al 2013, 2017, 2020, Gafforov et al 2017, Riebesehl and Langer 2017, Chen and Zhao 2020).…”

“…Based on sequences of ITS and nLSU, Yurchenko et al (2020) revealed that Fasciodontia , Hastodontia , Hyphodontia , Lyomyces , Tubulicrinis and Xylodon grouped together and seven species clustered into Lyomyces . A taxonomic study of Lyomyces by Chen and Zhao (2020) plotted macro‐ and micromorphological characteristics onto an ITS‐based phylogeny and found that none of them are phylogenetically informative.…”
