A conspicuous crustose lichen, typical for smooth bark (especially beech, hornbeam and sycamore). It grows in various types of deciduous and mixed forests, from lowlands to mountains. It prefers habitats with humid microclimate in older forest stands. In the Czech Republic, however, it often grows on young trees, especially at their bases. It is a widespread species, but only locally abundant, both in the country and Europe.
In reality, it is a complex of species, but their distinction is very difficult. Some taxa are determined based on morphological characters (e.g. G. pulverulenta, G. betulina, G. macrocarpa), but their delimitation does not correspond to phylogenetic lineages. Here, we prefer a broad species concept and use a single name for all potential species.
