Brianaria bauschiana (Körb.) S. Ekman & M. Svensson

Besides B. tuberculata, this is another rather rare representative of the genus in the Czech Republic. This taxon has a suboceanic geographical range. Recently, it has been recorded only from few localities, out of which only from tree it has been published: the Kamenice gorge in Bohemian Switzerland National Park (Czarnota 2004, Palice et al. 2007), the Rychlebské hory Mountains (Czarnota 2007) and (with a question mark) the trachyte quarry at Vrátenská hora Hill in the Kokořín region (Peksa et al. 2007). Earlier, it was reported only from the Drahanská vrchovina Highlands (Vězda 1978). It has a similar ecology as its related species, i.e. it occurs on shady overhanging acid rocks in areas with a relatively higher air humidity (so-called aero-hygrophile or aero-hygrophyte). According to certain literature, this lichen prefers a higher amount of iron in the substrate (Vězda 1978, Purvis & Halls 1996). Brianaria bauschiana can potentially be mistaken for the common species Psilolechia clavulifera (Czarnota 2004).
