Albugo tragopogonis, Sunflower White Rust, is an oomycete plant pathogen, although some sources still regard it as a fungal organism.
Albugo tragopogonis is the old name for Pustula tragopogonis[1], the causal agent of white blister disease on goatsbeard (Tragopogon spp.). Currently, also sunflower white blister rust is attributed to this pathogen, but this has not yet been confirmed by molecular phylogenetic studies.
