Abstract

Uromyces lomandracearum is described from leaves of Lomandra spp. in New South Wales and South Australia, and leaves of Acanthocarpus verticillatus from Western Australia. A pycnial/aecial rust on fruit of A. verticillatus from Western Australia is described as Aecidium acanthocarpi. These are the first rusts recorded on genera of Lomandraceae. The relationship of these rusts to one another, and to rusts recorded on other liliaceous hosts, is considered in the light of changing plant classifications. Sori of U. lomandracearum in most collections on Lomandra are heavily parasitised by Sphaerellopsis filum and the effect of this on the disease symptoms produced is discussed.
