摘要
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.
