Gyalecta fagicola (Hepp ex Arnold) Kremp.

The most abundant epiphytic Gyalecta species in the Czech Republic, occurring from lowlands to mountain areas. However, even this species is relatively rare in the country and seems to be locally more abundant only in the southwestern part of Bohemia. It is a microlichen, requiring a slightly nutritious bark. Unlike most of its relatives, it can inhabit a smooth bark of relatively young trees and, in moister forests, even their (often already dying) twigs. In densely forested areas, this species can be found also on solitary trees in alleys or abandoned gardens. The most common porophytes are Fagus, Quercus, Acer platanoides, Salix and Ulmus. Less often, it can be found on fruit trees, such as Malus or Pyrus. Historically, it has been recorded in the Czech Republic (and recently in the neighboring countries) on Abies alba.
