Systematics and phylogeny in Agaricales (gilled fungi), higher Basidiomycota. I am specially interested in the genus Cortinarius and related genera. Cortinarius is the largest genus of ectomycorrhizal basidiomycetes. More than 500 species are recorded in Norway, and more than 2000 species on the world scale. In boreal coniferous forests Cortinarius spp. takes about 70 % of the total basidiocarp biomass per year. They may therefore be of great importance for the trees in these forests. The various Cortinarius species occupy different ecological niches; in Norway from nemoral oak forest to medium arctic dwarf willow tundra. Some species are sensitive towards man made pollutions, other tolerant. They can therefore be used in monitoring the environment. A couple of species, i.e. Cortinarius rubellus and C. orellanus, contains the extremely toxic substance orellanine. Other Cortinarius species contain vividly coloured pigments, e.g. anthraquinones.
Ectomycorrhiza in boreal, coastal, and arctic-alpine ecosystems. Especially the basidiomycetous ectomycorrhiza formed by arctic-alpine plants as Salix herbacea, Salix polaris, Dryas octopetala, and Bistorta vivipara, or by the coastal Salix repens inhabiting sand dunes and heaths is of interest. Here very little have been done up to now, and we have only scanty information about the basidiomycetes building ectomycorrhiza with these plants.
Evolution in fungi both on a large scale, the Fungal kingdom, or on limited scale, as e.g. Cortinarius and other agarics.
