Wedin M., Baloch E. & Grube M. (2002): Parsimony analyses of mtSSU an nITS rDNA sequences reveal the natural relationships of the lichen families Physciaceae and Caliciaceae, Taxon, 51(4): 655-660

The phylogenetic relationships of the lichenised families Caliciaceae and Physciaceae (Lecanorales, Ascomycota) are investigated with parsimony analyses of combined mtSSU and nITS rDNA sequences. Physciaceae include two well-supported groups, which correspond to the informally recognised "Buellia-group" and "Physcia-group". The prototunicate, mazaedia-forming representatives of Caliciaceae are derived from within Physciaceae, and fall within the "Buellia-group". Nomenclatural consequences of two … Read more...

Wedin M., Döring H. & Gilenstam G. (2004): Saprotrophy and lichenization as options for the same fungal species on diffferent substrata: environmental plasticity and fungal lifestyles in the Stictis-Conotrema complex, New Phytologist, 164: 459-465

• Lichenization is one of the most important fungal lifestyles and lichen fungi are assumed to form obligate symbioses with their photobionts. Here we test if lichenized and non-lichenized samples in three cases of closely related lichenized Conotrema and saprotrophic Stictis (Stictidaceae, Ostropales, Ascomycota) in northern Scandinavia, form distinct monophyletic groups (= species). • We applied phylogenetic species recognition, by analysing fungal DNA sequence data from four independent genomic … Read more...

The family Stictidaceae (Ostropales, Ascomycota) contains both lichenized and nonlichenized fungi. Here, we test if Conotrema (lichenized) and Stictis (non-lichenized) as currently delimited are distinct monophyletic genera, by parsimony and parsimony jackknifing analyses of combined nuclear rDNA (ITS and partial LSU rDNA) and mitochondrial SSU rDNA sequence data matrices. The study includes four species of Stictis, three species of Conotrema, and representatives of the related Schizoxylon (lichenized), … Read more...

Wedin M., Döring H., Nordin A. & Tibell L. (2000): Small subunit rDNA phylogeny shows the lichen families Caliciaceae and Physciaceae (Lecanorales, Ascomycotina) to form a monophyletic group, Canadian Journal of Botany, 78: 246-254

A phylogenetic analysis based on small subunit (SSU) rDNA sequences shows the lecanoralean lichen families Caliciaceae and Physciaceae form a well-supported monophyletic group within the order Lecanorales (Ascomycotina). Support for this relationship is present from anatomical data, in particular data from spore ontogeny, where close similarities between the pattern of development of spore surface structures in the two families are pointed out. The Caliciaceae–Physciaceae group is characterized … Read more...

Wedin M., Jørgensen P.M. & Ekman S. (2011): Vahliellaceae, a new family of cyanobacterial lichens (Peltigerales, Ascomycetes), Lichenologist, 43(1): 67-72

The recently described genus Vahliella (Peltigerales, Ascomycetes) has repeatedly appeared outside the Pannariaceae in molecular phylogenies. Here we include data from additional species of the genus and utilize mtSSU rDNA and RPB1 sequences to confirm its placement as the sister to a group consisting of Lobariaceae, Massalongiaceae, Nephromataceae and Peltigeraceae, in the Peltigerales. The new family Vahliellaceae Wedin, P. M. Jørg. & S. Ekman is described for the genus, and its morphological … Read more...
