Few studies have been conducted on Mycena species in Hunan Province, China. During our research on the species diversity of Mycena in Hunan Province, we identified approximately 30 Mycena species based on morphological and molecular evidence. Five species are recognized herein as new to science, namely, M. fulvomarginata, M. huangsangensis, M. hongfengensis, M. subroriduliformis, and M. roseolamellata. The phylogenetic analyses of a combined ITS and LSU sequence dataset revealed that five new species each formed an independent lineage that could separate phenotypically similar and phylogenetically related species. Descriptions, photographs, and phylogenetic analysis results are provided for the five new species, along with the comparisons with related species. A key to all Mycena species found in Hunan is also provided.
