Melanohalea elegantula (Zahlbr.) O. Blanco & al.

Melanohalea elegantula is an isidiate epiphytic lichen, very similar to the common M. glabratula, from which it may be most securely distinguished by the negative reaction of medulla with chlorine (C-). The species grows on bark of a variety of deciduous trees, such as beeches, ashes, sycamore maples and oaks. It may be found from lowlands to mountains, usually on old solitary trees in avenues, parks, orchards, etc. The lichen is widespread in most of Europe except for boreal regions. In the Czech Republic, there are only a few dozens of recent records scattered across lower and middle elevations. Most probably, the species is more common in the country, but overlooked.
