This list was derived from the list at Index Fungorum online and includes all species known to have been described in or transferred to the genus Resupinatus. Other lamellate species that may belong in Resupinatus could be among those described in Acanthocystis, Agaricus, Calathinus, Crepidopus, Geopetalum, Hohenbuehelia, Lentinus, Panellus, Panus, Pleuropus, Pleurotellus, or Pleurotus (or other genera!). Reduced or cyphelloid taxa that may belong here may be found in Cyphella, Lachnella, Maireina, Peziza, Porotheleum, Solenia, and Theleporus (or other genera!). Graduate student Jennifer McDonald is tracking down these lost taxa in her revision of the cyphelloid Resupinateae. The list below is in the form of name, author(s), date of transfer to or description in Resupinatus, citation, type locality. Where there is known or suspected to be no holotype specimen, the type locality is indicated in square brackets. Varieties are listed but not numbered; forms ("forma") are not listed.
