Abstract: The phylogenetic placement of the genus Maronina was studied, based chiefly on phenotypic characters such as thallus colour and anatomy, secondary chemistry, the anatomy of the excipulum and the ascus-type. DNA sequence data of mitochondrial and nuclear ribosomal loci from some of the species support the hypothesis that Maronina is nested within Protoparmelia. Hence, Maronina is reduced to synonymy with Protoparmelia. Comparison of genetic distances suggests that the two varieties within M. orientalis should be regarded as distinct species. Consequently, the new combinations Protoparmelia australiensis (Hafellner & R. W. Rogers) Kantvilas et al., P. corallifera (Kantvilas & Papong) Kantvilas et al., P. hesperia (Kantvilas & Elix) Kantvilas et al., P. multifera (Nyl.) Kantvilas et al., and P. orientalis (Kantvilas & Papong) Kantvilas et al. are proposed.
Notes: New combinations: Protoparmelia australiensis (Hafellner & R. W. Rogers) Kantvilas, Papong & Lumbsch, Protoparmelia corallifera (Kantvilas & Papong) Kantvilas, Papong & Lumbsch (stat. nov), Protoparmelia hesperia (Kantvilas & Elix) Kantvilas, Papong & Lumbsch, Protoparmelia multifera (Nyl.) Kantvilas, Papong & Lumbsch and Protoparmelia orientalis (Kantvilas & Papong) Kantvilas, Papong & Lumbsch.
