A subspecies with mainly (anisotomous-) dichotomous branching, a powdery surface of the central cavity of the podetia and common presence of squamatic acid. It grows on acidic soil on screes, heathlands, peatbogs and near rock outcrops. It has oceanic tendencies in Europe and is rare in central Europe. In the Czech Republic, the lichen can be found on humid mountain screes, e.g., in the Krkonoše, Brdy and Hrubý Jeseník Mts. It was not distinguished in the past, so, older records are included in the C. uncialis agg. here.taxonomic classification:
