Rudaea

Rudaea is a largely obsolete genus of red algae, formerly encompassing a group of filamentous marine algae now classified within other genera, primarily within the order Nemaliales. The name "Rudaea" is infrequently encountered in modern algological literature, as the classification of red algae has undergone significant revisions based on molecular and morphological data. Historical descriptions of Rudaea species often lacked sufficient detail for accurate placement using current taxonomic standards. Consequently, specimens once assigned to Rudaea have been reclassified into more well-defined and phylogenetically consistent genera. The primary distinguishing characteristics that were used to define Rudaea, such as branching patterns and reproductive structures, are now known to be more variable or less unique than previously thought. Modern researchers typically consult taxonomic databases and phylogenetic analyses to correctly identify and classify related red algae species.
