Ciri dan struktur

Buellia saxorum forms a moderately thick crust-like growth (thallus) on its substrate. The thallus has a distinctive appearance with a network of fine cracks (described as "-cracked" in technical terminology) and displays a white to pale yellow-grey colouration. One of its distinctive features is the black border () that clearly defines its edges, often creating a mosaic pattern where multiple thalli meet. When stained with iodine, the inner layer (medulla) turns blue. The reproductive structures (apothecia) measure between 0.3 and 1 mm in diameter and sit on the surface of the thallus rather than being embedded within it. These apothecia have a flat to slightly convex dark disc surrounded by a prominent true rim (). Under microscopic examination, the upper layer of the apothecia () appears brown and does not react with nitric acid. The spore-producing layer (hymenium) lacks oil droplets. The spores (ascospores) are divided by a single septum (internal partition) and measure 10–18 by 5–9 micrometres (μm). They have walls that are uniformly thickened and smooth. They are of the Physconia-type The asexual reproductive structures (pycnidia) are abundant, producing spindle to cylinder-shaped spores (conidia) that measure 4–7 (–9) by about 1 μm. When subjected to chemical spot tests, the thallus is C+ (red), K+ (yellow), Pd (± yellow), and UV−. These reactions indicate the presence of two secondary metabolites: atranorin and gyrophoric acid. Lecanoric acid is present in trace amounts.

Ringkasan sumber

Buellia saxorum is a species of saxicolous (rock-dwelling) crustose lichen in the family Caliciaceae. It forms a moderately thick, white to pale yellow-grey crust with a network of fine cracks and a distinctive black border where it meets other lichen thalli, creating a mosaic pattern. The lichen's reproductive structures appear as small dark discs up to 1 mm in diameter on the surface of the thallus. First described by the Italian botanist Abramo Bartolommeo Massalongo in 1852, B. saxorum can be identified by its chemical spot test reactions due to the presence of atranorin and gyrophoric acid.
