Nomenclatural notes
The genus Tremella Linnaeus (1753: 1157) was lectotypified by Tremella nostoc Linnaeus by Donk (1958: 245). As this is an entity with a later starting point (ICBN Art. 13.1, Nostocaceae heterocystaceae), under the provisions of ICBN Art. 13.2, all included species in the genus Tremella thus also have a later starting point (1 January 1886), regardless of their current generic placement. Tremella difformis Linnaeus (1755: 429) is thus not a valid name dating from 1755. Nostoc marinum C. Agardh (1812: 45) is similarly invalid. The earliest valid name that can be used for the entity widely known as Leathesia difformis is Chaetophora marina Lyngbye (Pedroche et al. 2008: 60). - (12 Mar 2009) - M.D. Guiry
