Candelariella placodizans is newly reported from China. It was collected on exposed rocks with mosses on the alpine areas of Taiwan and Yunnan Province, China at elevation between 3200-4400 m. Molecular phylogenetic analyses based on ITS rDNA sequences were also performed to confirm the monophyly of the Chinese populations with respect to already existing sequences of the species, and then further to examine their relationships to other members of the genus. An identification key to all 14 known taxa of Candelariella in China is provided.
