“…Lyomyces macrosporus was sister to L. allantosporus, but morphologically L. allantosporus differs in having porulose hymenophore and suballantoid to allantoid, narrower basidiospores (7-9 × 3-3.8 µm, Yurchenko et al 2017). Lyomyces wuliangshanensis grouped closely with L. mascarensis, but L. mascarensis differs from L. wuliangshanensis by having thin-walled generative hyphae and presence of capitate cystidia (17-38 × 3.5-6 µm, Yurchenko et al 2017 ; L. capitatocystidiatus by grandinioid hymenophore with arachnoid-farinaceous hymenial surface (Xiong et al 2009); L. microfasciculatus by minutely odontioid hymenial surface and small emerging fascicles of flexuous hyphae (Yurchenko and Wu 2014); L. tenuissimus by much thinner basidiomata and non-encrusted, subicular hyphae, shorter cystidia and shorter basidia (Yurchenko et al 2013).…”

“…The members of Lyomyces grow on dead, still-attached or fallen branches of angiosperms, on dead wooden and herbaceous stems, or occasionally on gymnosperm wood (Yurchenko et al 2017). Twentythree species are currently known in Lyomyces worldwide (Rabenhorst 1851;Karsten 1881Karsten , 1882Peck 1903;Bourdot and Galzin 1911;Cunningham 1959Cunningham , 1963Wu 1990;Hjortstam and Ryvarden 2009;Yurchenko et al 2013Yurchenko et al , 2017Gafforov et al 2017;Riebesehl and Langer 2017) and five species were recorded in China (Xiong et al 2009;Gafforov et al 2017;Riebesehl and Langer 2017).…”

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

“…Langer 1994, p. 143 for illustration) and Nepal (Hjortstam and Ryvarden 1984) were originally identified as X.lanatus . Hyphae and spores of this species were also depicted by Yurchenko et al (2013) under the name X.lanatus . These two species and other morphologically similar taxa are compared in the Discussion section below; a key is also presented.…”

“…We retain the same diagnostic features, noted in the protologue (basidiomata with well-developed woolly subiculum, terminal vesicular structures on subicular hyphae, poorly differentiated subhymenium, encrusted thick-walled hyphae in tooth apices and capitate cystidia) and add that walls of basidia and subhymenial hyphae directly under hymenial elements are slightly but distinctly thickened. The illustration of Xylodonlanatus from Taiwan, provided by Wu (1990), also shows basidia with walls thickened below, but hyphal pegs appear different from X.lanatus s.s. We have also determined that X.echinatus (Yurchenko et al 2013) is the most morphologically similar species to X.lanatus s.s. A key to the taxa in the X.lanatus group is presented here.…”

Xylodon (Hymenochaetales, Basidiomycota) is the largest segregate genus of Hyphodontia s.l. Based on molecular and morphological data, 77 species are accepted in Xylodon to date. Phylogenetic analyses of ITS and 28S sequences, including 38 new ITS and 20 28S sequences of Xylodon species, revealed four species new to science. The new taxa X.exilis, X.filicinus, X.follis and X.pseudolanatus from Taiwan, Nepal, Réunion, Belize, and USA are described and illustrated. In addition, species concepts for Odontiavesiculosa from New Zealand and Xylodonlanatus from U.S.A. are revised and the new name X.vesiculosus is proposed. Phylogenetic analyses of the ITS region placed X.spathulatus, X.bubalinus and X.chinensis in a strongly supported clade and demonstrated that they are conspecific. Palifer and Odontiopsis are synonymised under Xylodon based on morphological and sequence data. The following new combinations are proposed: X.erikssonii, X.gamundiae, X.hjortstamii, X.hyphodontinus, X.septocystidiatus and X.verecundus. Line drawings of X.cystidiatus, X.hyphodontinus, X.lanatus and X.vesiculosus, as well as photographs of X.raduloides basidiomata, are provided. A key to X.lanatus and similar species is presented.

“…Riebesehl & Langer based on the character of the thick-walled basidiospores. However, Xylodon anmashanensis is distinguished from X. gossypinus by having the irpicoid to odontioid hymenial surface and longer basidiospores (up to 7.5 µm long) [13]; X. crassisporus differs from X. gossypinus by having only one type of capitate cystidia and wider basidiospores (5.5-6 × 4-4.5 µm) [53]; X. pruinosus differs from X. gossypinus by its grandinioid to odontoid hymenial surface and the presence of clavate to spathuliform cystidia [26]; X. rickii is separated from X. gossypinus by having the ochraceous hymenial surface with small brown dots and the presence of two types of cystidia: encrusted cystidia and capitate cystidia [54]; X. septocystidiatus is distinguished from X. gossypinus by its grandinioid hymenial surface and the presence of septocystidia [23].…”

Three wood-inhabiting fungal species, Xylodon gossypinus, X. macrosporus, and X. sinensis spp. nov. were collected from southern China, with the similar function to decompose rotten wood, which are here proposed as new taxa based on a combination of morphological features and molecular evidence. Xylodon gossypinus is characterized by the resupinate basidiomata with cotton hymenophore, and ellipsoid basidiospores; X.macrosporus is characterized by the resupinate basidiomata having the cracking hymenophore with pale yellowish hymenial surface, and larger basidiospores 8–10.5 × 7.5–9 µm; and X. sinensis differs by its grandinioid hymenial surface and subglobose basidiospores measuring as 3–5 × 2.5–4 µm. Sequences of ITS and nLSU rRNA markers of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The ITS+nLSU analysis in Hymenochaetales revealed that the three new species clustered into the Schizoporaceae family, located in genus Xylodon; based on the ITS dataset, X. gossypinus was a sister to X. ussuriensis; X. macrosporus closely grouped with X.follis with a high support; and X.sinensis was retrieved as two sisters to X. attenuatus and X. yarraensis with a lower support.
