 Both Lindau and Rea placed the family within the Auriculariales, but some subsequent authors placed it within the Tremellales.A radical revision was undertaken in 1984, when American mycologist Robert Joseph Bandoni used transmission electron microscopy to investigate the ultrastructure of the septal pore apparatus in the Auriculariales.This revealed that species of fungi with "auricularioid" basidia were not necessarily closely related and that "Auricularia" had more in common with "Exidia" and its allies (with "tremelloid" basidia), than with other auricularioid fungi.
