| Sumario: | The genus <i>Cantharellus</i>, commonly known as chanterelles, has recently been divided into six subgenera; however, wider sampling approaches are needed to clarify the relationships within and between these groups. A phylogenetic overview of <i>Cantharellus</i> subgenus <i>Parvocantharellus</i> in China was inferred based on the large subunit nuclear ribosomal RNA gene (nrLSU), the DNA-directed RNA polymerase II subunit 2 (<i>rpb</i>2), and the transcription elongation factor 1-alpha (<i>tef</i>1). A total of nine species from China were assigned to the subgenus, including seven novel species, namely <i>C</i><i>antharellus</i><i>aurantinus</i>, <i>C. austrosinensis</i>, <i>C. galbanus</i>, <i>C. luteolus</i>, <i>C. luteovirens</i>, <i>C. minioalbus</i>, and <i>C. sinominior</i>, and two known species, namely <i>C. albus</i> and <i>C. zangii</i>. The detailed descriptions and illustrations were provided based on the newly obtained data, with the comparisons to closely related species. <i>C. zangii</i> was restudied based on the paratype specimens and multiple new collections from the type locality. Futhermore, the Indian species <i>C. sikkimensis</i> was identified as a synonym of <i>C. zangii</i> based on the morphological and molecular analyses. A key to the Chinese species belonging to the subg. <i>Parvocantharellus</i> is also provided. |
