Deskripsi

Nine collections of gymnopoid fungi were studied based on morpho-molecular characteristics. The macromorphology was made according to the photograph of fresh basidiomata and field notes, while the micromorphology was examined via an optical microscope. Simultaneously, the phylogenetic analyses were performed by maximum likelihood and Bayesian inference methods based on a combined dataset of nrITS1-nr5.8S-nrITS2-nrLSU sequences. Integrated analysis of these results was therefore, <i>G. efibulatus</i> belonging to sect. <i>Androsacei</i>, <i>G. iodes</i> and <i>G. sinopolyphyllus</i> belonging to sect. <i>Impudicae</i> and <i>G. strigosipes</i> belonging to sect. <i>Levipedes</i> are proposed as new to science. The detailed descriptions, colour photos of basidiomata and line-drawings of microscopic structures are provided. The comparisons with closely related species and a key to known species of <i>Gymnopus</i> s. str. reported with morpho-molecular evidence in China is also given.
