Myllys L., Källersjö M. & Tehler A. (1999): Variable sizes of introns in the SSU rDNA in three species of Roccella (Arthoniales, Euascomycetes), Current Genetics, 36: 79-85

Three species of the lichenized fungus Roccella (Arthoniales, Euascomycetes), R. canariensis, R. tuber- culata and R. montagnei, were found to possess inser- tions in the ®rst half of the nuclear SSU rDNA. Both the number and the type of these insertions varied between and within species. At position 516 the insertions be- longed to group-IC1 introns with a characteristic sec- ondary structure and conserved sequences. At three positions, 300, 330 and 393, the insertions were short and lacked … Read more...

Grube M. & Kroken S. (2000): Molecular approaches and the concept of species and species complexes in lichenized fungi, Mycological Research, 104(11): 1284-1294

The concept of species and species complexes of lichenized fungi is reviewed in the light of recent molecular approaches. Species concepts based on chemistry, morphology, reproductive mode, photobiont choice and habitat preference provide working hypotheses from which the delimitation of species or relationships within species complexes can be tested with molecular data. In studies in which a single locus such as ITS is used, a phylogenetic species concept can be applied only when the sequence data … Read more...

Grube M., Baloch E. & Arup U. (2004): A phylogenetic study of the Lecanora rupicola group (Lecanoraceae, Ascomycota), Mycol. Res., 108(5): 506–514

A molecular phylogeny of the Lecanora rupicola group is presented, based on ITS sequence analyses. The study includes saxicolous and corticolous members of the Lecanora rupicola group as well as other Lecanora species with pruinose apothecia. A phylogenetic hypothesis for species in Lecanora s. lat. and various other genera in Lecanoraceae, based on an alignment-free distance estimation technique, shows that the Lecanora rupicola group forms a monophyletic clade within Lecanoraceae. Affinities to … Read more...

Gargas A., DePriest P., Grube M. & Tehler A. (1995): Multiple origins of lichen symbioses in fungi suggested by SSU rDNA phylogeny, Science, 268: 1492-1495

Phylogenetic hypotheses provide a context for examining the evolution of heterotrophic lifestyles. The lichen lifestyle, which is the symbiotic association of fungi with algae, is found in various representatives of Dicaryomycotina, both Ascomycetes and Basidio- mycetes. A highly resolved parsimony analysis of small subunit ribosomal DNA (SSU rDNA) sequences suggests at least five independent origins of the lichen habit in disparate groups of Ascomycetes and Basidiomycetes. Because lichen associations … Read more...

Ekman S. & Tønsberg T. (2002): Most species of Lepraria and Leproloma form a monophyletic group closely related to Stereocaulon, Mycol. Res., 106 (11): 1262–1276

The phylogenetic position of members of the entirely asexually reproducing lichen-forming genera Lepraria and Leproloma was investigated using sequence data from the ITS1-5.8S-ITS2 and small subunit (SSU) nuclear ribosomal DNA. Phylogenetic reconstructions were carried out using a likelihood-based Bayesian Markov chain Monte Carlo (MCMC) tree sampling technique and the unweighted least squares optimality criterion, the latter based on maximum likelihood distances obtained via an alignment-free distance … Read more...
