Buellia schaereri is a species of lichen in the family Caliciaceae. It was formally described as a new species in 1849 by Italian botanist Giuseppe De Notaris.[2] The botanical name honours Swiss pastor and lichenologist Ludwig Schaerer.[3] It is a widely distributed lichen, occurring in Africa, Asia, Northern and Central Europe, Macaronesia, Central America, and North America. It grows on the bark and wood of trees, especially conifers and oak.[4]

Description

Buellia schaereri has a thin, effuse, pale grey thallus. It has dark brown to black apothecia that measure 0.2–0.3 mm in diameter, with a flat to convex disc. The ascospores it makes are smooth and thin-walled with a single septum and typical dimensions of 6–10 by 2.5–4 μm. Pycnidia are visible as tiny (50–70 μm) black specks on the thallus surface; they are often numerous. They produce short oblong to ellipsoid conidia measuring 2–3 by 1–1.4 μm.[4]
