Usage of the applet:

top left – Character panel: selection of characters. Characters are classified according to their (statistical) reliability status: ● with high reliability (preferably to be selected when starting an identification procedure), ○ with mean, and · with low reliability.
top right – Character states or numeric data panel: preselection of states of the selected character. For selecting more than one character state at the same time, press the <CTRL> button plus the respective character states. (To finalize the query for a selected character, click the <Select> or <Add> menu button and then persue the identification process with another character.)
bottom left – Query criteria panel: display of previous character state selections. It is possible to deselect a previous choice by selecting it and subsequently pressing the <Remove Selection> button.
bottom right – Matching items panel: display of matching items (selecting any item will bring up a complete description of that item). Selecting a taxon with the right mouse button will bring up a context menu with various links to lichen images and websites providing further taxonomic information. Images from selected reliable sources are available, if the respective link is highlighted in green. (Images to be accessed via LIAS light context menu are copyrighted by the copyright holder(s) as indicated below the respective thumbnails.)
