Bacidia arceutina (Ach.) Arnold

An epiphyte usually growing on smooth and naturally nutrient-rich bark of deciduous trees (e.g. Acer platanoides) in moist valleys or old-growth forests. The species has a suboceanic distribution. In the Czech Republic, it is relatively rare and historically rarely reported. It is linked to rather low and middle elevations with a mild climate. Interesting and relatively unusual is its repeatedly recorded recent saxicolous occurrence in the Czech Republic (calcareous sandstone, flysh, basalt).
