| description: | o Subproject 1: Delimitation of species and genera in the groups of cetrarioid and parmelioid lichens (fam. Parmeliaceae, Ascomycota) according to their phylogenetic affinities - will test the hypotheses that some cetrarioid lichen genera (e.g. Cetrelia, Esslingeriana, Parmelaria, Platismatia) are phylogenetically more closely allied to parmelioid than to other cetrarioid taxa; that the "chemical" species of Cetrelia can also be distinguished on the basis of molecular characters; the genus Tuckermannopsis has been used lately as a "warehouse" and is in need of modern revision, applying both morphological and molecular characters; the generic position of a few cetrarioid species (e.g. "Cetraria" leucostigma, "Cetraria" melaloma, "Nephromopsis" weii ) should be cleared up. o Subproject 2: Systematics of the lichenicolous genus Abrothallus (Ascomycota: inc. sed.) - will assemble all the data concerning the genus Abrothallus; compile an original data matrix of all known morphological and anatomical characters and to check (using phylogenetic analysis) whether the separation of the described species is reasonable; make suggestions (using phylogenetic analyses of DNA sequences) concerning the delimitation of species and the systematic position of the genus. o Subproject 3: Delimitation and suggested systematic position of the genus Lepraria (Ascomycota: inc. sed.) and allied taxa - will prepare a systematic revision of the sterile lichen genus Lepraria; check, using phylogenetic analysis, whether the separation of species (described mainly based on the secondary compounds) is also supported by molecular characters; test substratum preferences of different Lepraria species; verify (using phylogenetic analyses of DNA sequences) the systematic position of the genus. |
