Often known as the "scrambled egg lichen"
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.

|UKBAP Signposting Actions:|
|1.||Monitor the extant sites every 6 years to ensure the mossy open calcareous grassland habitat required by this species is being maintained.|
|2.||The habitat is susceptable to enrichment, and therefore would benefit from a reduction of agricultural and atmospheric pollutants through the implimentation of agri-environment schemes|
|3.||Where this species is declining trial habitat restoration by turf stripping and moniroting re-colonisation.|
