Mallocybe , a member of the ectomycorrhizal mushroom family Inocybaceae , is a newly elevated genus based on Inocybe subg. Mallocybe . Although new species of Mallocybe have continuously been discovered worldwide during recent decades, species native to China are poorly documented. Members of the genus are frequently characterized by the presence of phaseoliform basidiospores and short, catenate cheilocystidia. Here, we describe three new Mallocybe species from China featuring elongate cheilocystidia that were revealed through morphological and molecular analyses: M. pallidipes collected from Populus in northeastern China, M. aurantiodisca discovered in subtropical evergreen broad-leaved forests dominated by Castanopsis in Zhejiang and Guizhou provinces, and M. longicystis found in fagaceous forests in tropical and subtropical China. According to a multi-gene phylogenetic analysis, which resolved the genus into three major clades, the three new species group with three North American species in a fully supported clade. Finally, we discuss the systematic position of the new species and infrageneric phylogeny of the genus.
