Lobarina scrobiculata (Scop.) Nyl.

A conspicuous macrolichen that grows on various deciduous wooden plants and on mossy rocks. The last Czech populations (from the surroundings of Třebíč and Velké Meziříčí) were also found on the latter substrate. The species prefers open damp natural forests. It requires constant humidity and is sensitive to air pollution and eutrophication. The species range has mostly temperate-suboceanic character. Lobarina scrobiculata is currently very rare in central Europe, it has disappeared from most of the area. In the Czech Republic, the lichen has got extinct probably in the first half of the 20th century (the last exsiccates were collected in 1929), probably due to the increase in emissions of SO₂, the intensification of agriculture, and possibly also changes in the global climatic conditions. However, also in the past, the species used to be reported sporadically, from a limited number of localities at middle and high elevations.
