Ciri dan struktur
The thallus of X. aureola is bright yellow, orange, or orange-red with a foliose morphology. Mutatoxanthin, a carotenoid important in the protection of the photosynthetic component against harsh sunlight, represents 94.4% of the total carotenoid content in X. aureola. Of all Xanthoria species, X. aureola contains the most mutatoxanthin. X. aureola is often confused with closely related species X. parietina and X. calcicola. In comparison, X. aureola has a brighter thallus color as well as a considerably thicker medulla (187 mm compared to 114–120 mm). Additionally, the rough upper surface of X. aureola contains few apothecia and does not contain soredia or isidia; laminar structures are lobules. Last, substrate is important: X. aureola is restricted to seashore rocks, while X. calcicola and X. parietinia can be found on almost any rock or wall.
Habitat dan peran ekologis
Xanthoria aureola grows on exposed maritime rocks in sunny areas. It generally grows on nutrient-rich, siliceous rocks, as well as limestone and lignum. It is found on European coasts 0–150 meters above sea level. Some countries in which X. aureola is commonly found include Spain, Portugal, France, Ireland, Denmark, Sweden, Norway, Italy, and the UK. It usually grows next to X. parietina, but in greater abundance and on exposed rock. The algal symbiont in X. aureola is Trebouxia. Trebouxia fixes 14C mainly into ribitol during photosynthesis; approximately 80% is ribitol, 5% is sucrose, 4% is organic acids, and 9% is baseline CH. Therefore, ribitol is the main way in which carbohydrates are transferred among symbionts in the thallus. Environmental stress (i.e., increased UV light) enhances the creation of reactive oxygen species (ROS), including superoxide and hydrogen peroxide. Membrane integrity was measured via conductivity and potential photosystem II (PSII) efficiency (Fv/Fm), with the former being a more accurate measure. High UV, salt, and heavy metal concentrations increased membrane dissolution and electrolyte leakage. X. aureola was more resistant to salt than other lichenized species Lobaria pulmonaria and Parmelia sulcata.
