- Two fifths of the species in Ascomycota are lichen-forming, of which 10% and 3-4% have cyanobacteria as the primary and secondary photobionts respectively. To study the evolution of cyanobacterial symbioses, the phylogenetic relationships within the Ascomycota have been reconstructed. Phylogenetic analyses were made using direct optimization of nuclear SSU and LSU rDNA sequences under the parsimony optimality criterion. Our results indicate repeated evolution of the mutualistic assemblages between fungi and cyanobacteria. The stability of the cyanobacterial symbioses and the effects of photobiont alteration on the evolution of ascomycetes are discussed, as is the taxonomy of some cyanobacterial lichen taxa, and some future perspectives on the evolution of these ecologically important assemblages.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Seven new species of Caloplaca are described, the isidiate Caloplaca clavatoisidiata and C. sipmanii, and five fertile species, C. bastowii, C. beaugleholii, C. dahlii, C. jerramungupensis and C. norfolkensis. The new species are distinguished from related species by morphological, anatomical and chemical characters which are described in detail. The new combination Caloplaca soredians (Müll.Arg.) Elix, S. Y. Kondr. & Kärnefelt is made.

-
Tidskriftsartikel (refereegranskat)abstract
- new species of Enterographa (Arthoniales: Roccellaceae) is described. E. kina- baluensis from Kota Kinabalu is characterized by the presence of punctiform soralia and norstictic acid. The saxicolous Fulvophyton serusiauxii is described from coastal Mexico and differs from the corticolous F. klementii in having much smaller ascospores.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Populations previously included in Xanthoparmelia lineola and X. digitiformis from Australia and North America have been investigated using ITS rDNA sequences, chemistry and morphology and have been compared with possible related species. The new species, Xanthoparmelia knudsenii Elix, A. Thell & Søchting is described and the new combination Xanthoparmelia rimalis (Kurok.) Elix, A. Thell & Søchting is proposed
