 WORKING KEYS TO LICHENS IN COSTA RICA As our studies on the lichen biotas of Costa Rica develop, we will place working keys to selected groups on this page. The keys are semi-interactive; they work in a two-column frame window which allows to quickly switch between main and part keys and to conveniently view images of selected species. All keys will also be available for download in traditional format as PDF files. Thus far, the following keys are available: Working key to genera and species of Graphidaceae in Costa Rica (18 genera and 82 species) © Robert Lücking (partly based on Staiger 2002 and Wirth & Hale 1963, 1978) Download this key as [PDF] file Key to species of Graphis in Costa Roca (63 species) Keytable to species of Graphis worldwide (164 species) Bilingual key to species of Gyalideopsis worldwide (94 species) Working key to species of Usnea (in preparation, coming soon!)
