Abstract english

The phylogeny of two lichens, Cetraria obtusata from the Alps and Coelopogon epiphorellus occurring in the southern hemisphere is studied. A DNA-matrix based on ITS 1 and ITS 2 sequences of the rDNA is compared with a data set composed of morphology and secondary chemistry characters in phylogeny analyses using PAUP 4.0. The two data sets were entirely congruent. Neither Cetraria obtusata nor Coelopogon epiphorellus, both earlier segregated from the Cetraria aculeata group (Coelocaulon), are closely related with Cetraria s. str. Ecology notes of the two species are added and their phylogenetic affinities are discussed.
