Species of Rhytismatales on Berberis from China

Three species of Rhytismatales on Berberis were found from Sichuan and Yunnan provinces in China. Two of them were described as new species to science, namely Hypoderma minteri and Lophodermium johnstonii . The third one was a known species, Hypoderma berberidis . The phylogenetic relationships of these species within the Rhytismatales were analyzed based on internal transcriber spacer ribosomal DNA. The results showed that the species of the Rhytismatales on Berberis , unlike most species on pines, were not closely related. Three ITS sequences from GenBank, named there as Lirula macrospora , were used in this study, but were found to be from misidentified sources. A key to species of Rhytismatales on Berberis worldwide is also given.
