In India the cultivated oyster mushroom Pleurotus sajor-caju (Fr.) Singer is attacked by the larvae of two species of Phoridae, Megaselia pleurota Disney sp. n. and M. scalaris (Loew). The new species is described. Biological data and damage symptoms are reported for both species. Serious economic damage is also caused by a bacterium associated with M. scalaris. The identities of the two Megaselia species, previously reported attacking this fungus, are called into question.
