Umbilicaric acid is an organic polyphenolic carboxylic acid made by several species of lichen. It is named after Umbilicaria.^[1] Umbilicaric acid is a tridepside, containing three phenol rings in orsellinic acid moieties.^[2]

Identification of unbilicaric acid can be important in the identification of lichen species.^[2]
