ABSTRACT=<p><italic>Gymnopus</italic> sect. <italic>Impudicae</italic> is a poorly studied group around the world. However, it is well known for its pungent smell—a total of five species from China belonging to sect. <italic>Impudicae</italic> were recorded, and included four species new to science—<italic>G. epiphyllus, G. cystidiosus, G. subdensilamellatus</italic>, and <italic>G. subpolyphyllus</italic>—which were delimited and proposed based on morphological and molecular evidences, and one new record from Henan, Jiangxi, and Gansu Province, China—<italic>G. densilamellatus</italic>. Detailed descriptions and illustrations were presented as well as comparisons to similar species. Phylogenetic analysis inferred from the ITS and nLSU dataset supported the <italic>Gymnopus</italic> as a monophyletic genus which was defined by Oliveira et al., and the novel species grouped as separate lineages within it. A Key to the reported species of <italic>Gymnopus</italic> sect. <italic>Impudicae</italic> is also provided.</p>
