Bacidia rosella (Pers.) De Not.

Bacidia forming prominent pink apothecia on a grey-green thallus. It grows on old deciduous trees with higher bark pH (mainly Acer platanoides and beech), often accompanied by the related, more common B. rubella. In Europe, B. rosella is widely distributed mainly across the Mediterranean and the temperate zone, often in more or less continental regions. In the Czech Republic, the lichen occurs from uplands to mountains mainly in scree forests. At lower elevations, more localities are reported from river valleys in south Moravia, e.g. around the Oslava and Dyje rivers. In Czech sites, the species is usually very rare, linked to a few old trees.
