Aureoarbor Molinari & Sánchez Ocharan , nom. nov.

Replaced name: Chrysodendron Pascher, Archiv für Protistenkunde 57: 320, 1927 (Ochrophyta, Ochromonadaceae ), non Chrysodendron Mier y Terán & Berlandier (1832: 7) , Berberidaceae .

Type: Chrysodendron ramosum Pascher (monotypic genus at the time of publication).

Notes: While Chrysodendron Mier y Terán & Berlandier is a suppressed name included in the Appendix V of the ICN, and a synonym of Berberis L. ( Marroquín, 1993), later homonyms are still illegitimate unless conserved, according to Art. 53.1, note 2. Aureoarbor ramosa forms sessile colonies of cells joined by stalks ( Chapman & Chapman, 1973). Originally described from samples taken in Austria and Czech Republic, it has been recently reported from Lake Uvildy in the southern Urals, Chelyabinsk Oblast, Russia ( Mavrina, 2016). The algal genus is renamed using a portmanteau of aura arbor, a Latin translation of the original Greek name, with same meaning of “golden tree”.
