description | Three wood-inhabiting fungal species, <i>Xylodon laceratus</i>, <i>X</i><i>. montanus,</i> and <i>X</i><i>. tropicus</i> spp. nov., were collected from southern China, here proposed as new taxa based on a combination of morphological features and molecular evidence. <i>Xylodon laceratus</i> is characterized by the resupinate basidiomata with grandinioid hymenophore having cracked hymenial surface, and ellipsoid basidiospores; <i>X. montanus</i> is characterized by the annual basidiomata having the hard, brittle hymenophore with cream hymenial surface, and ellipsoid to broadly ellipsoid basidiospores (3.9–5.3 × 3.2–4.3 µm); and <i>X. tropicus</i> is characterized by its grandinioid hymenophore with buff to a pale brown hymenial surface and subglobose basidiospores measuring 2–4.8 × 1.6–4 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 of the order Hymenochaetales indicated that the three new species clustered into the family Schizoporaceae, located in genus <i>Xylodon</i>; based on further analysis of ITS dataset, <i>X</i><i>. laceratus</i> was a sister to <i>X. heterocystidiatus</i>; <i>X</i><i>. montanus</i> closely grouped with <i>X. subclavatus</i> and <i>X. xinpingensis</i> with high support; while <i>X.</i><i>tropicus</i> was retrieved as a sister to <i>X. hastifer</i>. |
