Biatorella fossarum (Dufour ex Fr.) Th.Fr.

A little known terricolous representative of the genus, usually growing on exposed calcareous soil. The only historical report on the occurrence of this species in the Czech Republic comes from Olomouc, where it was collected by R. Picbauer in a limestone quarry near Grygov (Kovář 1911). Latterly, its presence has not been confirmed. In the Catalogue of lichens in the Czech Republic (Vězda & Liška 1999) and later published national checklists (Liška et al. 2008, Liška & Palice 2010), it is incorrectly associated with the name B. hemisphaerica. This closely related, alpine terricolous species probably does not occur in the Czech Republic at all.
