ResumoAbstract The phylogenetic relationships of the lichenised families Caliciaceae and Physciaceae (Lecanorales, Ascomycota) are investigated with parsimony analyses of combined mtSSU and nITS rDNA sequences. Physciaceae include two well‐supported groups, which correspond to the informally recognised “ Buellia ‐group” and “ Physcia ‐group”. The prototunicate, mazaedia‐forming representatives of Caliciaceae are derived from within Physciaceae, and fall within the “Buellia‐group” . Nomenclatural consequences of two different scenarios of changes in the present classification are discussed.
