Wedin M. & Tibell L. (1991): Two new species of Sphaerophorus (Caliciales) from New Zealand, New Zealand Journal of Botany, 29(3): 287-293

The new species Sphaerophorus whakapapaensis Wedin and S. ohlssonii Wedin (Sphaerophoraceae, Caliciales, lichenised ascomycetes) are described from New Zealand. The ascospore ontogeny is described. The spore ornamentation of both species consists of mazaedial material added to the spore wall after the spores have been released from the asci. Concentric bodies occur in young ascospores. The conidiophores are branched and produce conidia both acrogenously and pleurogenously. The conidiophores thus … Read more...

Wedin M. & Wiklund E. (2004): The phylogenetic relationships of Lecanorales suborder Peltigerineae revisited, Acta Univ. Ups. Symb. Bot. Ups., 34(1): 469-475

We present maximum parsimony and parsimony jackknifing analyses of the cyanobacterial lichens in the Lecanorales suborder Peltigerineae (Lecanoromycetes, Ascomycota, Fungi) based on an earlier mtSSU rDNA dataset, but with additional taxa from the Pannariaceae s. lat. and the Coccocarpiaceae included. The results are discussed and compared with earlier analyses. The monophyletic suborder Peltigerineae includes the families Coccocarpiaceae, Collemataceae, Lobariaceae, Nephromataceae, Placynthiaceae, … Read more...

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., Könberg K. & Gilenstam G. (2005): Generic delimitations in the family Stictidaceae (Ostropales, Ascomycota): the Stictis-Conotrema problem, Lichenologist, 37(1): 67-75

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...
