This interesting site, by two Research Associates of the Department of Systematic Botany, University of Aarhus (Denmark), aims to provide a simple means for navigating through the various taxa of fungi. Currently covering 279 genera and 1,090 illustrated species, MycoKey includes "the genera of basidiomycota with stem and cap (Agarics, Boletes etc.), polypores and club fungi from Northern Europe (i.e. Europe north of the Alps)." A second version detailing "most genera of sexual fungi forming fruitbodies" is slated for release in summer 2001. To navigate the site, select the "easy" (pictorial characters only) or "full" (pictorial characters accompanied by descriptive botanical terms) version; then select the appropriate character and proceed to the next question. At any point, users may choose to browse images of all genera that apply to that description -- this includes close-up color images for each genus/species that fits the characters they have selected.
