Ganoderma is a genus of medicinally and economically important mushrooms in the family Ganodermataceae. Ganoderma species are popular medicinal mushrooms and their health benefits are well-documented. Ganoderma is a cosmopolitan genus that is widely distributed in both tropical and temperate regions. This genus is characterized by its unique laccate or non-laccate species with double-walled basidiospores. Here, we report on eight collections of G. gibbosum collected during surveys in Kunming, Yunnan Province, China. The specimens are described and illustrated based on macro- and micro-morphological characteristics. Total DNA of the eight G. gibbosum strains were extracted using the Biospin Fungal Extraction Kit following manufacturer protocol. Amplification of the Internal Transcribed Spacer (nrITS) region was carried out using ITS5/ITS4 primers and LROR/LR5 for the nuclear ribosomal large subunit 28S rDNA gene (LSU). Phylogenetic analysis with closely related species to G. gibbosum showed that all eight collections grouped with G. gibbosum with 100% bootstrap support. Phylogenetic similarity and morphological variations within the eight collections of G. gibbosum are discussed.
