Ten new species of <i>Inocybe</i> ( <i>Inocybaceae, Agaricales</i> ) from the Gaoligong Mountains, southwestern China

The genus Inocybe, a highly diverse lineage within the Inocybaceae, contains more than 1000 species worldwide. Species of this genus have been studied in many parts of China since the beginning of this century. However, the species diversity of the genus in southwestern China remains largely unknown. In the past few years, the authors made several forays in the Gaoligong Mountains, western Yunnan, making many collections of Inocybe species. Based on morphological studies and a three-locus (ITS-nrLSU-rpb2) phylogeny, ten novel species have been recognized, namely I. hirsuticeps, I. ceratina, I. longistipes, I. gracilipes, I. flocculosipes, I. flavocrocea, I. rufosquamosa, I. aculeata, I. dulongjiangensis, and I. squamulomarginata. They are described and characterized with morphological features and phylogenetic evidence.
