Biatora helvola is a corticolous crustose lichen occurring in boreal and montane spruce and spruce-fir-beech forests. After the last glaciation, spruce reinvaded Europe from three refugia situated in the Carpathians, southeastern parts of the Alps and the Ural Mts., resulting in a slightly disjunct distribution. Our aim was to find out whether the glacial fragmentation of the distributional area of spruce is reflected by genetic differences in a typical spruce-forest lichen. Collections of Biatora … Read more...

The ability of the internal transcribed spacers (ITS regions) of ribosomal DNA to resolve phylogenetic relationships within the euascomycetous order Arthoniales, focusing on the family Roccellaceae was investigated. The effect of alignment on phylogenetic hypotheses was evaluated. A data matrix from the ITS regions was constructed from 33 specimens representing 14 genera, including the outgroup Arthothelium spectabile. Six different alignments were analysed cladistically using parsimony jackknifing. … Read more...

Arup U. & Grube M. (1999): Where does Lecanora demissa (Ascomycotina, Lecanorales) belong?, Lichenologist, 31(5): 419-430

Lecanora demissa (Körb.) Zahlbr. is a crustose, lobate lichen that produces soredia and conidiomata but no apothecia. Its placement in Lecanora has long been questioned but nothing better has been proposed. We have studied the nuclear rDNA of the ITS regions and the SSU of L. demissa. In an alignment of the ITS regions of several representatives of Lecanora s. lat. it could clearly be shown by a PAUP analysis, using Aspicilia caesiocinerea as outgroup, that L. demissa does not belong to Lecanora. … Read more...
