In the framework of project Dryades
, the research group of the Dept. of Life Sciences (University of Trieste) has developed hundreds of digital identification keys (accessible through the web portal of project Dryades, http://dryades.units.it), as well as several textual versions downloadable in pdf format. A great amount of the interactive keys are also available for mobile devices, such as smartphones and table computers.
Among these, several are devoted to lichens.
