Description
Summary:The genus Australiaena (lichenized Ascomycetes, Physciaceae) with the single species A. streimannii sp. nov. is described as new from tropical Australasia. Morphologically it is characterized by crustose thalli with an often radiate-plicate margin, ascospores with a type-B ontogeny, and filiform spermatia. The chemistry of this taxon is diverse (lobaric acid, conlobaric acid, xanthones, gyrophoric acid, lecanoric acid, 5-O- ethylhiascic acid, perlatolic acid), and three chemotypes are distinguished.
