Ecology and distribution

About 40 ''Micropsalliota'' species have been described by Belgian mycologist Paul Heinemann and colleagues from the tropics of Africa, America, India, Indonesia, and Malaysia. Eleven new species from Thailand were added in 2010. '' Micropsalliota pseudoglobocystis'' is the first species of the genus reported from China. A new species '' Micropsalliota albofelina'' was described in 2021, it is also the first record of this genus in Vietnam.
