Protoparmelia atriseda (Fr.) R. Sant. & V. Wirth

A crustose lichen associated with hard and exposed siliceous rocks (usually granite), with high quartz content, where it typically grows at the upper edges. It is almost always accompanied by yellow Rhizocarpon species, which it parasites at the beginning of its development. In the Czech Republic, the lichen is scattered at the middle and higher elevations, mainly in the western part. It is abundant on screes in the Brdy highlands. The oldest known Czech specimens were collected in the 1930s by J. Nádvorník in the Žďárské vrchy hills (Poelt & Leuckert 1991). However, most of its records are recent, i.e. from the last three decades.
