A small epiphytic forest lichen, typically growing on shady and weathered ("more nutritious") bark of old deciduous trees or woody plants with naturally higher bark pH (e.g. Acer platanoides, A. campestre, Ulmus spp.). Most of recent records come from southwestern Bohemia, in particular from the Šumava Mts. However, it can be also found in forested valleys and ravines in southern Moravia, as well as scattered in old-growth forest reserves in the north-eastern part of the country.taxonomic classification:
