Identification keys

In the framework of project Dryades, the research group of the Dept. of Life Sciences (University of Trieste) has developed many online identification keys, as well as several textual versions downloadable in pdf format. In 2018, a new version of software FRIDA, by S. Martellos, was created to start work on an interactive lichen flora of Italy. FRIDA3.0 permits to create keys with both a multi-entry and a dichotomous query interface.

Keys from the Dryades portal
All of the keys listed below, plus several other keys to lichens produced with older versions of software FRIDA, are also accessible from the portal of Project Dryades. If you open a key from there, the graphic outline will be different (e.g. also the multi-entry keys are responsive, the generation of keys to remaining taxa is faster etc.).

Several keys are also available in stand-alone versions for mobile devices, such as smartphones and tablets, via the free app KeyToNature (available for both Android and iOS devices).
