Abstract: The resources of Tuber were investigated in Liupan mountain in 2019 and 2020. Twelve specimens of Tuber were collected and identified. After morphological observation and molecular phylogenetic analysis, the specimens were identified as T. lishanense, T. pseudohimalayense and T. umbilicatum, in which T. pseudohimalayense is with great economic value. Based on collected specimens, the morphological characters and variation of these three species were described and discussed in details. The results broaden distribution area of Tuber in China. The record and ecological data of Tuber in Liupan mountain were supplemented. It is the first time to confirm the distribution of these three Tuber spp.in Liupan mountain. The results are significant to the resources diversity, biogeographic and ecological study of Tuber in China.

Key words: Tuber lishanense, Tuber pseudohimalayense, Tuber umbilicatum, biogeography, ecological significance
