Notes: Marasmius was proposed by Fries (1836). This is a world-wide distributed genus which has been a topic of interest by researchers all around the globe. Presently, India hosts a record of ca. 75 species of Marasmius among which most of them have been reported from the southern Indian regions (Dutta et al. 2015). In this study, three new species of the Marasmius viz. M. benghalensis, M. jinfoshanensis and M. subtropicus are described from China and India based on evidence of morphology and phylogenetic analysis. The present study follows the latest treatment on Marasmius by Shay et al. (2017) and He et al. (2019).
Type species: Marasmius rotula (Scop.) Fr., Epicrisis Systematis Mycologici: 385 (1838) [1836-1838].
Other accepted species: Species Fungorum – search Marasmius.
