The new species, Menegazzia jamesii Louwhoff & Kantvilas from Victoria and Tasmania, closely related to M. pertransita (Stirt.) R. Sant., is described. Chemical and nomenclatural notes on M. caliginosa P. James & D. J. Galloway and M. pertransita are provided, and the new combination, M. stirtonii (Zahlbr.) Kantvilas & Louwhoff, is proposed. The name M. weindorferi (Zahlbr.) R. Sant., widely applied in Australian literature, is considered synonymous with M. pertransita, whereas M. bullata (Stirt.) Bitter is considered a synonym of M. stirtonii.
