Species of Micropsalliota (Basidiomycota, Agaricomycetes, Agaricales, Agaricaceae) are mainly distributed in tropical and /or subtropical regions. These fungi are saprophytic in general and can decompose lignin and cellulose, and thus have significant value in ecosystems. Research on the Micropsalliota has a long history of more than one hundred years. However, the molecular phylogenetic study on this genus is very limited and the phylogenetic relationships of species within this genus remain largely unresolved.
