The genus Schaereria Körb. in Australia

Abstract

AbstractFive 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.
