Flavoparmelia caperata is a lichen species commonly found in various regions, including the Comunidad Valenciana. This lichen is referred to locally as "Lichen de los muros," and it is easily recognizable due to its distinctive appearance.

Flavoparmelia caperata can be identified by the following characteristics:

• Coloration: The upper surface of this lichen is pale yellow-green, which often becomes more pronounced in moist conditions. Its color can sometimes vary to a dusty green or gray-green, depending on environmental factors and age.
• Texture: The surface is typically smooth, with a slight wrinkling as the lichen matures. It has a somewhat wavy appearance, contributing to its unique texture.
• Thallus Structure: It forms a leafy, or foliose, thallus with loosely attached lobes. The edges of these lobes tend to curl upwards, giving it a ruffled look.
• Habitat: Flavoparmelia caperata is very adaptable and can be found growing on a variety of surfaces, including tree bark, rocks, and sometimes soil. It favors well-lit, unabused areas, making it a common sight in both urban and rural settings.
• Distribution: This lichen is widespread, not only throughout the Comunidad Valenciana but also across Europe and other continents, benefiting from its ability to thrive in diverse environments.

This lichen species plays an important role in the ecosystem by providing habitat and food for various microorganisms and small animals. Moreover, like other lichens, Flavoparmelia caperata is an excellent indicator of air quality, as it is sensitive to air pollution, especially sulfur dioxide.
