Buellia aethalea

Ciri dan struktur

The thallus of this crustose lichen has a distinctive areolate structure, with the individual areoles varying considerably in their appearance. They typically range from 0.2–0.6(−1.2) mm in diameter, displaying an angular, irregular shape. The areoles can exhibit a pale to dark grey coloration, sometimes taking on a brownish tint that gives the thallus a discolored look. Separating the areoles is a narrow, black prothallus that helps delineate the edges of the thallus. Reproductive structures on this lichen are represented by its lecideine apothecia, which remain immersed within the thallus rather than developing a raised, sessile appearance. These apothecia are relatively small, measuring (0.1–)0.2–0.2(−0.5) mm in diameter. The apothecial margin is black, but indistinct and reduced, while the disc itself is flat and black, lacking any sort of pruina or surface bloom. The excipular anatomy of the apothecia is rather narrow and poorly differentiated. The inner hyphae are hyaline and prosoplectenchymatous, often resembling the orientation and appearance of the paraphyses. In contrast, the outer excipular hyphae are parallel, moderately swollen, and heavily pigmented in various shades of brown and greenish blue. This pigmentation of the outer exciple also extends into the brown epihymenium. The hymenium itself is hyaline and lacks any conspicuous oil droplets. The paraphyses exhibit a simple to moderately branched morphology, with their apical portions swollen and capped in a brown pigment. Turning to the asci, they are clavate in shape and contain 8 ascospores each. Those ascospores start out as a blue-green color but eventually mature into a dark brown hue.

Habitat dan peran ekologis

Buellia aethalea is widely distributed across temperate regions, with the species being commonly encountered in northern Europe. However, reports of its occurrence in North America are considerably scarcer. Within the Sonoran Desert region of North America, the lichen has been documented growing at higher elevations in the state of Arizona. Specific locations where B. aethalea has been observed include the San Francisco Peaks and the White Mountains. Ecologically, Buellia aethalea functions as an epilithic lichen, colonizing a variety of siliceous, or acid-based, rock substrates.

Reproduksi

Reproductive structures on this lichen are represented by its lecideine apothecia, which remain immersed within the thallus rather than developing a raised, sessile appearance. These apothecia are relatively small, measuring (0.1–)0.2–0.2(−0.5) mm in diameter. The apothecial margin is black, but indistinct and reduced, while the disc itself is flat and black, lacking any sort of pruina or surface bloom. Turning to the asci, they are clavate in shape and contain 8 ascospores each. Those ascospores start out as a blue-green color but eventually mature into a dark brown hue. They are 1-septate, broadly ellipsoid in shape, and become constricted with age, measuring (11–)11.6–[12.8]–14.1(−17) x (5–)7.2–[8.1]–8.9(−10) μm.
