LAND: A molecular phylogeny of the brown-spored agarics (Basidiomycota)

Tildelt: kr 2,1 mill.

The agarics with brownish spore prints embrace the families Cortinariaceae, Strophariaceae, Bolbitiaceae and Tubariaceae. In the Northern hemisphere, there is a vast number of brown-spored agarics, adapted to a variety of habitats. The phylogenetic relati onships between the large, brown-spored genera Cortinarius, Inocybe, Hebeloma, Galerina and Pholiota are largely unexplored. The main objective is to accumulate knowledge on the taxonomy, phylogeny and ecological diversification of brown-spored agarics. T he genus Galerina, which includes ca. 350 species world-wide, will be particularly focused. Species and infrageneric units in Galerina have hitherto been based on morphological and to a less extent ecological characters. We will infer the molecular phylog eny and test species boundaries and character evolution of the brown-spored agarics and the genus Galerina. The project is a DNA-sequence-based multi-locus phylogenetic approach. In addition, the AFLP technique, microscopy of sporocarps and compatibility testing of living culture isolates of species complexes in Galerina will also be accomplished. The genetic variation will be analysed by likelihood and parsimony-based inferential techniques. The project includes a PhD candidate and the contributions from four senior researchers.
