Abstract
In September 2012, a rust fungus on Cyclachaena xanthiifolia was recorded in two localities near Odessa, Ukraine (46°0' N, 29°40' E and 46°25' N, 30°10' E). Sequences of the 28S subunit of the nuclear ribosomal DNA show that the rust on C. xanthiifolia is conspecific with Puccinia helianthi. Ukraine is apparently the only country outside of the USA from which P. helianthi has been noted on C. xanthiifolia.
Keywords: Puccinia helianthi, Cyclachaena xanthiifolia, morphology, LSU sequences, Ukraine
