Morphological and Phylogenetic Analyses Reveal Three Novel Species of () from Yunnan Province, China.

() is recognized as a valuable medicinal resource in Taiwan, China. Additionally, it serves as a traditional folk medicine for treating neurotic epilepsy in Malaysia. This study involved the collection of six specimens of from Yunnan Province, China. Employing multigene phylogenetic analysis of DNA sequences, including internal transcribed spacer (ITS), nuclear large subunit (LSU), RNA polymerase II second largest subunit (2), translation elongation factor 1-alpha (1-α), mitochondrial small subunit (mtSSU), nuclear small subunit (nSSU) and morphological examinations, three new species, viz. , and , are introduced. is characterized by a central stipe basidiomata, an orbicular to suborbicular pileus, a grayish-yellow surface with alternating concentric zones and wavy margin-like petals and regular pileipellis cells (4-8 × 17-28 μm). is characterized by a long stipe and flabelliform basidiomata, a dark-grayish yellow-to-dark-yellow pileus surface, irregular pileipellis cells and wavy margin and ellipsoid basidia (8-11 × 9-13 μm). is characterized by a reniform basidiomata, a heterogeneous context and ovoid basidiospores (7.5-8.6 × 5.5-7.2 µm). A detailed description and illustrations of these new species are provided, as well as a morphological comparison with similar taxa.
