Abstract

White blister rust is one of the most common diseases in Brassicaceae. Recently, molecular approaches revealed that apart from Albugo candida, several other more specialized species of the genus are causing this disease on Brassicaceae and the diversity of this group still remains largely unexplored. All newly described species have so far been sampled only from a limited geographic range, except for Albugo species which followed their invasive host from Europe to other continents. In this study we show that a previously unknown species of Albugo is causing white blister rust disease on two species of Strigosella. This species can be distinguished from other species of the genus Albugo both by its phylogenetic position and its unique oospore ornamentation that might be an adaptation to the harsh environment of the host plants. As a consequence, Albugo arenosa is described and illustrated as a new species, so far known from Strigosella africana in Iran and Spain, and Strigosella brevipes in Iran. Apart from Albugo candida and Albugo lepidii, this is the third hitherto known species of Albugo s. str. with a confirmed native distribution range of several thousand kilometres.
