| Comments | Type by original designation (also monotypic). Information in Round, Crawford & Mann (1990): "Dimerogrammopsis, M. Ricard. Cryptogamie-Algologie, 8, 1987. T: D. furcigerum (Grunow) Ricard" is incorrect. There is no such article in Cryptogamie-Algologie 8 (neither in volumes 6 to 11), description found in Ricard 1987 (ref. 003201), Ricard does not specify that this is a new genus. This genus name is not validly published because a Latin description is lacking. |
