Echinodiscus Ginauensis
''Echinodiscus'' is the scientific name of several genera of organisms and may refer to: * ''Echinodiscus'' (echinoderm) Leske, 1778, an extant genus of sea urchins in the family Astriclypeidae **Fossil echinoderm genera with the name ''Echinodiscus'' have been described by d'Orbigny (1854) Worthen & Miller (1883) and Stürtz (1900). These names are junior homonyms * ''Echinodiscus'' (fungus) Etayo & Diederich (2000), a genus of fungi in the order Helotiales * ''Echinodiscus'' (plant) Benth.

Echinodiscus (echinoderm)
''Echinodiscus'' is a genus of sand dollars within the family Astriclypeidae. There are currently 14 species assigned to the genus, with a majority being extinct Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and ....

Junior Homonym
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon. The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is " valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a ''nomen oblitum'' and rendered unavailable, while the junior homonym is preserved as a ''nomen protectum''. :For example: :* Cuvier proposed the genus ''Echidna'' in 1797 for the spiny anteater. :*However, Forster had already published the name ''Echidna'' in 1777 for a genus of moray eels. :*Forster's use thus has priority, with Cuvier's being a junior homonym. :*Illiger published the replacement name ''Tachyglossus'' in 1811. Similarly, the International Code of Nomenclature for algae, fungi, and plants (I ...

Echinodiscus (fungus)
''Neoechinodiscus'' is a genus of two species of lichenicolous fungi with uncertain familial placement in the order Helotiales. Species: *'' Neoechinodiscus kozhevnikovii'' *'' Neoechinodiscus lesdainii'' These species used to be classified in ''Echinodiscus'', a genus proposed by Javier Etayo and Paul Diederich in 2000. Diederich subsequently discovered that the fungal use of the genus name was an illegitimate homonym, as it had already been used for a legume genus in 1837, as well as for a diatom A diatom (Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising sev ... genus in 1925. The replacement name ''Neoechinodiscus'' was proposed by Rubén Sierra and Eduardo Molinari-Novoa in 2020.
