AN ANNOTATED CHECKLIST OF PERONOSPORA SPECIES IN VICTORIA

All Victorian Peronospora specimens in herbarium VPRI were re-examined. Twenty-two species are listed here, and another four undetermined taxa are noted. Most species infect members of the Caryophyllaceae, Chenopodiaceae and Fabaceae. Only one specimen was encountered on a native Australian plant (Mentha laxiflora), but it could not be identified. The names applied to two groups of Peronospora species are of particular note. Firstly, as the only species of Trifolium to be infected by Peronospora in Victoria is T. repens, this species is treated as P. trifolii-repentis. Secondly, the Peronospora farinosa formae speciales classification for several taxa on the Chenopodiaceae has not been used. These taxa are treated as P. farinosa on Atriplex, P. effusa on Spinacia oleracea, P. chenopodii on Chenopodium album, and P. schachtii on Beta vulgaris. J. H. Cunnington (2008).
