De Clerck, O. & Coppejans, E.: Notes on Dictyota vieillardii and D. adnata (Dictyotaceae, Phaeophyta). - Taxon 46: 33-36. 1997. - ISSN 0040-0262.
Post considered Dictyota adnata Zanardini to be a synonym of D. vieillardii Kütz. However, examination of the type specimen of D. vieillardii proves it does not belong to the genus Dictyota but represents the Vaughaniella stage of a Padina species. D. vieillardii var. filiformis Kütz. is also shown to represent a Vaughaniella stage. The type specimen of D. adnata could not be traced and the designation of a neotype by Coppejans is confirmed.
