| Summary: | <i>Hydnum</i>, a well-defined genus in the family <i>Hydnaceae</i> (order <i>Cantharellales</i>), is characterized by its distinctive spine-bearing hymenophores. In this study, we performed a multi-locus phylogenetic analysis (ITS-nrLSU-<i>tef1</i>) of <i>Hydnum</i> species. Integrating morphological examinations and phylogenetic evidence, we identified and delineated five <i>Hydnum</i> species in China, which include four novel species (<i>Hydnum crassipedum</i>, <i>H. albomarginatum</i>, <i>H. fulvostriatum</i>, and <i>H. bifurcatum</i>) and the first record (<i>H. orientalbidum</i>) in Anhui Province. This study provides a comprehensive morphological description (including macroscopic morphology and microscopic structure), hand-drawn illustrations (encompassing basidiocarps, basidiospores, basidia, and pileipellis hyphae), morphological comparative analysis with similar species, and comparative phylogenetic analysis with related taxa. Furthermore, we developed a dichotomous key for identifying <i>Hydnum</i> species distributed in China. |
