The genus Artomyces (Auriscalpiaceae, Basidiomycota) from the Gaoligong Mountains and adjacent areas, southwestern China.

Three new species of Artomyces from the Gaoligong Mountains and adjacent areas of southwestern China, namely, A. brunneoalbus, A. hirtipes, and A. pteruloides, are described based on morphological characteristics, molecular phylogenetic evidence, and ecological traits. Two other species described recently, A. niveus and A. yunnanensis, have also been identified in the same area. In addition, the occurrence of A. pyxidatus in southwestern China and North Macedonia was confirmed. Our study indicated that the species diversity of Artomyces is relatively high in East Asia. To date, seven species of Artomyces have been reported from the region, including the aforementioned species and A. microsporus. Given the diversity of forest ecosystems, from tropical to temperate areas in China, additional species of the genus could be revealed in the future.
