ABSTRACT=<p><italic>Cystolepiota</italic> is a tiny lepiotaceous fungi. During our 3 years fieldwork, we found four new species of <italic>Cystolepiota</italic> from northeastern China. A phylogenetic study of a combined dataset of ITS+nrLSU+rpb2+tef1-α revealed that <italic>Cystolepiota changbaishanensis</italic> and <italic>Cystolepiota hetieri</italic> are sister clades; <italic>Cystolepiota hongshiensis</italic> belongs to <italic>Cystolepiota seminuda</italic> complex; <italic>Cystolepiota luteosquamulosa</italic> formed a clade not closely related with any other; <italic>Cystolepiota nivalis</italic> and <italic>Cystolepiota</italic> sp. (HMJAU68235) formed a sister clade. All new species are provided with descriptions, photos of the basidiomata, and colored illustrations of the microstructures. A key for the identification of <italic>Cystolepiota</italic> species from China is also presented.</p>
