Zhou Q.-M., Wei J.-C., Ahti T., Stenroos S. & Högnabba F. (2006): The systematic position of Gymnoderma and Cetradonia based on SSU rDNA sequences, Journal of the Hattori Botanical Laboratory, 100: 871-880

Phylogenetic relationships of Gymnodenna coccocarpum and Cetradonia linearis were investigated using nucleotide sequence data of the SSU rDNA. Our results show that Gymnodenna and Cetradonia form a clade, which is a sister group of Pycnothelia and Carassea. As a result, both Gynmoderma and Cetradonia are clearly members of the family Cladoniaceae and the family name Cetradoniaceae has to be abandoned. The SSU rDNA of Gymnoderma contains seven group I and one spliceosomal intron, the positions and … Read more...

Vivas M., Millanes A. M., Xavier Fihlo L., Honda N. K., Pereira E. C., Vicente C. & Legaz M.-E. (2006): Production of barbatic acid by immobilized cells of Cladonia miniata var. parvipes in calcium alginate, Journal of the Hattori Botanical Laboratory, 100: 855-863

Cell aggregates of Cladonia miniata var. parvipes immobilized in calcium alginate were used to assay their ability to produce barbatic acid. Immobilisates were supplied with sodium acetate or calcium acetate as a precursor for phenol biosynthesis, with ampicillin to prevent bacterial conta mination. Barbatic acid was actively produced during incubation, although cell vitality progressively decreased. Calcium acetate increased the rigidity and mechanical resistance of immobilisates and produced cell … Read more...

Vitikainen O. (2006): Peltigera tartarea, a new species from Arctic America, Journal of the Hattori Botanical Laboratory, 100: 853-854

Peltigera tartarea (Llano) Vitik. stat. et comb. nov. is reported from the arctic slope of Alaska and compared with allied species of the genus. Unlike many other species of the genus Peltigera, P venosa (L.) Baumg. has a narrow range of morphological variation and is mostly easy to identify. Therefore, the description of P venosa f. tartarea Llano, one of the few infraspecific taxa ever proposed in the species, arouses interest. According to Llano (1951), the form was fertile and its photo- biont … Read more...

Kärnefelt I. (1990): Evidence of a slow evolutionary change in the speciation of lichens, Bibliotheca Lichenologica, 38: 291-306

There are many known lichens which occur in rather isolated populations in the Southern Hemisphere. Several questions could be asked as to how these major disjunctions came to be established? Long distance dispersal through various dispersal mechanisms have been discussed as possible causes of major disjunctions among lichens and plants in general but events of plate tectonics have also been taken into consideration correlated with the timing of evolution of the various plant groups. The … Read more...
