A Bacidia genus member with a green areolate (not granular) thallus and grey to black apothecia. It can be distinguished from the anatomically similar species Toniniopsis separabilis by the unpigmented hypothecium. It is an epiphytic species, growing mostly on fertile weathered bark of older or fungus-infected deciduous trees, especially beeches. In the Czech Republic, the lichen is rare to scattered from lowlands to mountains. Most of the current records come from the southwestern part of Bohemia. However, there are also records from the vicinity of Prague (the Český kras karst, Voděradské bučiny), from southern Moravia (e.g. the confluence of the Morava and Dyje rivers and the Oslava valley), from the Žďárské vrchy Highlands (Žákova hora Hill) and from the Beskydy Mts. It is a lichen of conservation/bioindication importance as it is associated with old-growth (especially beech) forests, even in lower areas with drier climate. Within Europe, it can be considered a widely distributed, scattered species.taxonomic classification: most frequented synonyms:Bacidia circumspecta
