Marasmius asiaticus is a species of agaric fungus in the family Marasmiaceae.

Known only from a single collection made in Mount Nuang Forest Reserve (Peninsular Malaysia), it was described as new to science in 2009 by Tan and Dennis Desjardin under the name Marasmius distantifolius.

[1] This was later discovered to be an illegitimate homonym of a species named by William Alphonso Murrill in 1915,[2] now known as Marasmiellus distantifolius.

[3] Armin Mešić and Zdenko Tkalčec proposed the new epithet asiaticus, referring to its distribution.

[4] The original epithet, which combined the Latin distans ("distant") and -folius ("leaf"), alluded to the distantly-spaced gills.
