description Xanthoria candelaria Overview
Xanthoria candelaria is a yellow foliose lichen with small, finely divided lobes that may rise from the substrate and produce granular or farinose soredia. It occurs on bark, rock, detritus, fences, gravestones, walls, and other exposed, nutrient-rich surfaces. The name has also been applied broadly in older literature, and some modern treatments separate related material into other genera or species, including Xanthomendoza fulva.
help Xanthoria candelaria FAQ
What does Xanthoria candelaria look like?
It is a bright yellow-green foliose lichen with small clustered lobes. The leafy lobes make it look different from tightly crusted orange lichens such as Caloplaca saxicola.
Where does Xanthoria candelaria usually grow?
It commonly grows on nutrient-rich bark and branches, especially where bird nutrients or other mineral deposits enrich the surface. The catalog description places it widely across Europe.
Is Xanthoria candelaria a crustose lichen?
No. It is foliose, meaning it forms leaf-like lobes that are attached to the substrate but not completely crusted into it.
How can Xanthoria candelaria be confused with other yellow lichens?
Its yellow-green color can resemble other species in the Xanthoria group, including Xanthoria parietina. The small clustered lobes, bark habitat, and microscopic or chemical features help confirm the identification.
