Xanthoria calcicola

This foliose lichen grows on calcareous rock and stone work (and occasionally dusty trees) in eutrophic, well-lit, mild-temperate and costal regions of Europe and the Mediterranean. It has a yellow-orange to dark orange foliose thallus forming pleated lobes growing in large rosettes up to 20 cm in diameter. The center of the rosettes are covered in knobbly warts and granular isidia, and it only rarely produces apothecia. The presence of these isidia and the lack of apothecia is the best way to distinguish this lichen from the very similar looking X. parietina which is a lot more common and often grows on bark.

The aptly named seaside sunburst lichen - Xanthoria aureola - I think.

Orange! Are you glad to see this pop of color in the midst of winter? 🧡🌳 Introducing Xanthoria, the vibrant orange lichen that brings a ray of sunshine to the dreariest of days! This fascinating organism is not just a beautiful sight, but also plays a crucial role in our ecosystem. 🌿Xanthoria is a slow-growing, long-lived symbiotic relationship between fungi and algae, providing a home for many insects and serving as an indicator of air quality. Let's give a shoutout to this unsung hero of the natural world! 🙌🏼💚 #xanthoria #lichenlove #naturephotography #naturelovers #ecology #biology #symbiosis #outdooradventures #natureart #airquality #ecosystems #lichensofinstagram #foraginglife #foraging #foraginguk https://www.instagram.com/p/Coguclks1Ig/?igshid=NGJjMDIxMWI=

They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches (fruticose); flat leaf-like structures (foliose); crust-like, adhering tightly to a surface (substrate) like a thick coat of paint (crustose); a powder-like appearance (leprose); or other growth forms.

FOTD #043 : maritime sunburst lichen! (xanthoria parietina)

maritime sunburst lichen (AKA common orange lichen, yellow scale & shore lichen) is a foliose lichen in the family teloschistaceae. it has been found in north america, africa, asia, europe & australia !! it often grows in hardwood forests in broad, low-elevation valleys, or in populated areas.

the big question : can i bite it?? like most lichens, it is inedible, though it may have medicinal uses.

x. parietina description :

"the vegetative body of the lichen, the thallus, is foliose, & typically less than 8 centimetres (3.1 in) wide. the lobes of the thallus are 1–4 mm in diameter, & flattened down. the upper surface is some shade of yellow, orange, or greenish yellow, almost green when growing in shady situations, while the lower surface is white, with a cortex, & with sparse pale rhizines or hapters. in xanthoria parietina, the thickness of the thalli is known to vary depending on the habitat in which it grows. the lichen pigment parietin gives this species a deep yellow or orange-red color."
