Description & Identification

Easily identified by the non-specialist,  Fulgensia fulgens is a squamulose lichen made up of overlapping, lemon-yellow scales, with a lobed margin, and are slightly pruinose. When well developed the thallus is distinctly placodioid. The centre of the thallus is often paler and either has scattered, rounded, dark orange fruits up to 1.5 mm in diameter, and narrow lobe-like vegetative propagules called schizidia, which break off exposing the white medulla. The thallus has a purple reaction (K+ p) when potassium hydroxide is applied due to the presence of the lichen substance Physcion.
