COMMENT

This species was not mentioned in the monograph of the genus Riccia L. in the Mediterranean area by Jovet-Ast (1986), and no other record or reference to it has been found (Ros et al. 2007a). Söderström et al. (2016) considered that there are serious doubts about the value of the taxon. It was included in Hodgetts et al. (2020) as a species occurring in territories adjacent to Europe.
