Scientific Name: Lampsilis siliquoidea
Species Authority: (Barnes, 1823)
Common Name(s):
English Fatmucket
Synonym(s):
Lampsilis luteola (Lamarck, 1819)
Lampsilis luteola (Lamarck, 1819)
Lampsilis radiata luteola (Lamarck, 1819)
Lampsilis radiata luteola (Lamarck, 1819)
Lampsilis radiata siliquoidea (Barnes, 1823)
Lampsilis radiata siliquoidea (Barnes, 1823)
Taxonomic Notes: The combination Lampsilis radiata luteola has been used incorrectly in place of Lampsilis siliquoidea and resulted in some confusion. For example, Lampsilis radiata luteola cited in Oesch (1984, 1995) is actually Lampsilis siliquoidea but the two names are not considered synonyms nor is siliquoidea considered a form or subspecies of radiata. Unio (= Lampsilis) luteola, previously confined to the Susquehanna and Mohawk Rivers (Johnson 1969), falls within the overall range of and is considered a junior synonym of Lampsilis radiata and not as a senior synonym of Lampsilis siliquoidea (see Turgeon et al. 1998).

Note that Watters et al. (2009) conclude that Unio siliquoidea Barnes, 1823, is a junior synonym of Unio luteola Lamarck, 1819, that intergraded with Lampsilis radiata radiata in northern New York in the Finger Lakes, Erie Canal, Mohawk, and upper Susquehanna Rivers; and therefore synonymize Lampsilis siliquoidea with Lampsilis radiata as a subspecies- Lampsilis radiata luteola.

A list of synonyms for this species can be found on The MUSSEL project web site (Graf and Cummings 2011).
