Peronospora atriplicis-hortensis Săvulescu & Rayss, 1932; P. atriplicis-tataricae Oescu & Rădulescu, 1933; P. nitens Oescu & Rădulescu, 1933; P. tatarica Săvulescu & Rayss, 1932.

The Index Fungorum (2013) states that minor is a junior synonym of P. arborescens, according to the older literature a parasite of Papaver and its close relative Meconopsis, on the base of the revision by Voglmayr ao (2014) of P. rhoeas alone. These genera stand so far removed from Atriplex that the synonymy is unlikely.
