The genus name of Marcelleina is in honour of Marcelle Louise Fernande Le Gal (1895-1979), who was a French mycologist and lichenologist.
According to a standard reference text, Marcelleina is widespread in distribution and contains nine species; two new species were since published in 2010 and 2011.
