Abstract english

A preliminary systematic position of the genus Cetrariella based on sequences from the ITS region is discussed. Cetrariella delisei and C. fastigiata appear as not very closely related species. Both species form a monophyletic sister group to Cetraria and should presumably stay as a separate segregate. The evidences from morphological data and data from secondary chemistry, however, strongly support the separation of the genus Cetrariella. We still need much more molecular data from the examined groups for a better judgment on these characters in systematic evaluations.
