The genus Albugo s.str. causes white blister rust on four families of the Brassicales, Brassicaceae, Capparaceae, Cleomaceae, and Resedaceae. Recent phylogenetic studies have revealed that several host specific lineages are present within Albugo on Brassicales, while it was also confirmed that Albugo candida has an exceptionally wide host range which extends from Brassicaceae to Cleomaceae and Capparaceae. The Albugo species infecting the Resedaceae was attributed in monographic studies as well as local floras to either A. resedae or, applying a broader species concept, to A. candida. In the present study, A. resedae specimens were morphologically and molecularly compared to the five Albugo species so far confirmed from Brassicales, A. candida, A. koreana, A. laibachii, A. lepidii, and A. voglmayrii. Both morphological differences of oospore ornamentation and phylogenetic analysis of cox2 mtDNA sequences provided evidence that A. resedae is distinct from A. candida and from the additional four species so far described from Brassicaceae. It thus seems possible that so far unknown factors restrict Albugo candida to Brassicaceae and its sister families, Cleomaceae and Capparaceae.
