Chrysothrix candelaris, commonly known as the gold dust lichen or egg yolk lichen, is a distinctive sorediate crustose lichen formed by the mutualistic association of a fungal partner (Chrysothrix candelaris, class Arthoniomycetes) with green algal photobionts. The lichen is immediately recognizable by its bright chrome-yellow to yellow-orange powdery soredia — granular reproductive propagules — which form a continuous farinose crust on the bark of acidic-barked trees, rock surfaces, and decaying wood in shaded, humid conditions. The vivid yellow color is due to calycin and other xanthone pigments. C. candelaris is widely distributed across Europe, North America, and South America, growing on smooth-barked deciduous and coniferous trees, boulders, and cliff faces in woodland and boreal forest habitats. It is assessed as Least Concern by the IUCN, reflecting its broad distribution and tolerance of a range of microhabitats. The lichen serves as a bioindicator of old-growth forest conditions and is sometimes used in air quality monitoring, as it is moderately sensitive to sulfur dioxide pollution. C. candelaris reproduces vegetatively through the dispersal of soredia by wind, water, and animals, which carry photobiont and mycobiont cells together.

Cilician Fir

Cilician fir (Abies cilicica) is a large conifer in the family Pinaceae, native to the Taurus and Anti-Taurus mountains of southern Turkey and the mountain ranges of Lebanon and Syria, including Mount Lebanon and the Ansariyah range. It grows at elevations between approximately 1,000 and 2,400 meters in cool, moist montane forests, often forming pure stands or mixing with cedar of Lebanon (Cedrus libani), oriental beech (Fagus orientalis), and other conifers. Trees can reach 30 meters in height with a conical crown and upswept branches bearing glossy, dark green needles. The species is classified as Near Threatened by the IUCN, reflecting ongoing habitat pressures including deforestation, overgrazing, charcoal production, and the long-term effects of climate change reducing precipitation in the eastern Mediterranean. Populations in Syria and Lebanon have been severely reduced by historical forest clearance and remain highly fragmented. Turkish populations in the Taurus and Anti-Taurus are more extensive and partly protected within national parks and forest reserves. Cilician fir forests provide critical watershed protection, biodiversity habitat, and climate regulation services in a region facing intensifying water stress. Reforestation efforts using native seed sources and protection of remaining natural stands are priority conservation actions. The species is occasionally cultivated as an ornamental in European gardens.
