description Three new wood-inhabiting fungi, <i>Hyphoderma crystallinum</i>, <i>H. membranaceum,</i> and <i>H. microporoides</i> spp. nov., are proposed based on a combination of morphological features and molecular evidence. <i>Hyphoderma crystallinum</i> is characterized by the resupinate basidiomata with smooth hymenial surface scattering scattered nubby crystals, a monomitic hyphal system with clamped generative hyphae, and numerous encrusted cystidia present. <i>Hyphoderma membranaceum</i> is characterized by the resupinate basidiomata with tuberculate hymenial surface, presence of the moniliform cystidia, and ellipsoid to cylindrical basidiospores. <i>Hyphoderma microporoides</i> is characterized by the resupinate, cottony basidiomata distributing the scattered pinholes visible using hand lens on the hymenial surface, presence of halocystidia, and cylindrical to allantoid basidiospores. Sequences of ITS+nLSU rRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. These phylogenetic analyses showed that three new species clustered into <i>Hyphoderma</i>, in which <i>H. crystallinum</i> was sister to <i>H. variolosum</i>, <i>H. membranaceum</i> was retrieved as a sister species of <i>H. sinense</i>, and <i>H. microporoides</i> was closely grouped with <i>H. nemorale</i>. In addition to new species, map to show global distribution of <i>Hyphoderma</i> species treated in the phylogenetic tree and an identification key to Chinese <i>Hyphoderma</i> are provided.
