【Objective】 The purpose of this research is to investigate the species diversity of Mount Kunyu in Shandong Province and further identify its species composition and distribution. 【Methods】 Morphological, anatomical, chemical characters and molecular phylogenetic analysis based on ITS sequences were used in this research. 【Results】 Three lichens species new to China, Lepraria harrisiana Lendemer, Leprocaulon nicholsiae Lendemer & E. Tripp, Brownliella kobeana (Nyl.) S.Y. Kondr., K?rnefelt, A. Thell, Elix, Jung Kim, A.S. Kondr. & Hur, were discovered during a taxonomical study of the lichens from Mount Kunyu, Shandong Province. Descriptions in details and morphological photographs of these three species are provided. Specimens examined are deposited in SDNU (Lichen Section of Botanical Herbarium, Shandong Normal University). 【Conclusion】This research shows high species diversity of lichens in Mount Kunyu.
