ABSTRACT=<p><italic>Micropsalliota</italic> is a relatively small genus containing only 62 previously identified species. Here, we describe six new taxa of <italic>Micropsalliota</italic> based on morphological and phylogenetic analyses: <italic>M. minor, M. ovalispora, M. pseudodelicatula, M. rufosquarrosa, M. tenuipes</italic>, and <italic>M. wuyishanensis</italic> and a new record taxon to China. The first Maximum likelihood and Bayesian analyses of a three-gene dataset (ITS, LSU, and <italic>rpb2</italic>) separated the genus into 18 weakly to strongly supported major clades and subclades, but only a few subclades were synapomorphies. According to phylogenetic analyses, <italic>M. cornuta</italic> does not belong in <italic>Micropsalliota</italic>. A key to 20 species of <italic>Micropsalliota</italic> in China is provided.</p>
