Lichen [SEP] Identification methods
Lichen identification uses growth form and reactions to chemical tests. The outcome of the "Pd test" is called "Pd", which is also used as an abbreviation for the chemical used in the test, para-phenylenediamine. If putting a drop on a lichen turns an area bright yellow to orange, this helps identify it as belonging to either the genus "Cladonia" or "Lecanora".
