a
The list includes only those Clostridium spp. that (i) have been validly described and listed in the List of Prokaryotic names with Standing in Nomenclature (http://www.bacterio.net/, Euzéby, 1997), (ii) do not belong to the family Clostridiaceae, and (iii) fall within the suggested new genera. Proposed type species are listed first and indicated in bold typeface.

These species designations have been changed: Gottschalkia purinilytica, Gottschalkia angusta, Tyzzerella nexilis, Tyzzerella colina, Tyzzerella neopropionica, Tyzzerella piliformis, Tyzzerella propionica.
