Phylogeny and species delimitation of North American Leccinoid fungi.

Leccinoid fungi include ectomycorrhizal members of the Boletales (Basidiomycota, Agaricomycetes) with scabrous to pseudo-scabrous stipes and non-ornamented spores, commonly collected in summer and fall in diverse forest types throughout North America. Previous phylogenetic work on leccinoid fungi has focused primarily on European species; this project centers around North American species. Using collections made by the authors and herbarium material, the initial focus of the research will be the oak-associated leccinoid fungi, which have traditionally been placed in Leccinum, Boletus, and Leccinellum. Sequences from two nuclear ribosomal DNA regions (LSU and ITS) and from one protein-coding gene (TEF1-alpha) will be amplified, sequenced, and analyzed in combination with morphological and ecological data to resolve the continent’s major species groups. The working hypothesis for the research, suggested by previous molecular studies, is that ectomycorrhizal host specificity roughly correlates to major clades among the leccinoid fungi, and that species groups can be further delineated with a combination of molecular and morphological factors. Preliminary results of the ongoing research will be presented.
