Using the results of recently published thoroughly-samples phylogenies, the authors from Australia, France and Switzerland, publish a revised classification of the order Oxalidales, which contains the plant families Brunelliaceae, Cephalotaceae, Connaraceae, Cunoniaceae, Elaeocarpaceae (incl. the former Tremandraceae) and Oxalidaceae. Some of these families are well-represented in Australia. One new suborder, five new subfamilies, and three new tribes are described.

The author from the Tasmanian Herbarium reviews the lichen genus Inoderma, which was split recently from Arthonia, and accepts two species for Australia: one described as new, the other an existing species that is transferred to Inoderma. In total, the genus now has seven species worldwide. A species of fungus that grows on Inoderma lichens is also reported: Chaenothecopsis brevipes.
