Three new species of Collybia in China, Collybia clavipes, C. carnea and C. violea, are originally reported and described based on morphological characteristics and molecular data. This study provides detailed morphological descriptions of these three new species of Collybia, which can be accurately distinguished from other species within the genus Collybia. Phylogenetic relationships of Clitocybaceae were analyzed using a four-loci combined dataset (ITS-nrLSU-rpb2-tef1-&alpha:), and the results show that the three newly discovered species of Collybia form three distinct lineages, respectively. Based on the combination of morphological and molecular methods, these three newly collected species of Collybia are confirmed as new to science. A theoretical basis is provided for the species diversity of Collybia.
