The genus Marasmius Fr. (Basidiomycota, Marasmiaceae) is cosmopolitan in distribution with about 600 well-accepted epithets. The characteristic features of the genus include an in situ reviving basidiomata; conic to convex pileus with striate to sulcate margin; adnexed to adnate attachment of lamellae; tough, filiform stipe, and dextrinoid tramal hyphae. Recent advances in molecular phylogenetic protocols restrict the genus to a monophyletic lineage, including sections Globulares, Hygrometrici, Leveilleani, Marasmius, Neosessiles, Scotyphysini and Sicci.
