Abstract

Five species of Schaereria Körb. are known to occur in Australia (including Tasmania). The new species S. australis Kantvilas is described from alpine Tasmania and New South Wales; it is characterized by a thallus lacking lichen substances, apothecia with only brown pigments, and ellipsoid, uniseriate ascospores, 10−17 × 6−9 μm. Also treated are: S. bullata Kantvilas, endemic to Tasmania; S. dolodes (Nyl. ex Hasse) Schmull & T. Sprib., first described from North America and recorded here for the first time from the Southern Hemisphere (Tasmania); the bipolar S. fuscocinerea (Nyl.) Clauzade & Cl. Roux and the Australian endemic S. xerophila Rambold & H. Mayrhofer, both recorded for the first time from Tasmania. The species are illustrated and an identification key is provided.
