Abstract

During 2016 and 2018, Lactuca undulata plants showing symptoms typical of white blister rust were collected in the province of South Khorasan, Iran. Phylogenetic analysis resolved the position of specimens in the genus Pustula. The specimens were characterised by oospore size and ornamentation, and size of secondary sporangia. In addition to morphology, phylogenetic analysis also suggests a new species for the genus distinct from other established Pustula species, which is described here as Pustula lactucae sp. nov. Scanning electron microscope illustrations are also provided.


Keywords:     Asteridae, obligate biotroph, Peronosporomycetes, SEM, semiarid region.
