Bellicidia incompta (Borrer) Kistenich, Timdal, Bendiksby & S.Ekman

A species forming dark green thallus and black apothecia. It is an epiphytic lichen with a very specific ecology – it usually seeks out wounded patches with leaking sap and locally elevated pH on trunks of deciduous trees (often Acer platanoides and Ulmus sp., but also Fagus, A. pseudoplatanus etc.). Based on detailed knowledge of its ecology, the species can be found in various forest habitats with old deciduous trees, including parks. Sometimes, it occurs in the anamorphic stage, i.e. without apothecia but with numerous pycnidia. Even in this stage, the lichen may be easily recognised by its typical conidia and other microscopic features. In central Europe, this species is rather rare. Currently, scattered localities are known in the Czech Republic, ranging from lowlands to mountains. However, due to the specific ecology, the lichen is very rare in most of them.
