Abstract [en]

A preliminary molecular phylogeny of 26 Aspicilia species based on nuclear rDNA ITS1-5.8S-ITS2 is presented and compared with the occurrence of some morphological features and secondary chemical products. Three major monophyletic groups were discovered, one including aspicilin-containing species with large spores and short conidia, a second with mainly arctic-alpine species with small spores, variable chemistry and conidium length, and a third group having spores of variable size, conidia of medium size and containing β-orcinol depsidones. An extended analysis of the second subgroup, including additional species and sequences, resulted in the synonymization of a number of names. Lectotypes are designated for A. mashiginensis, A. mastrucata, A. obscurata and A. permutata, and the lectotypification of A. verruculosa is discussed.
