Parmeliopsis ambigua (Wulfen) Nyl.

A tiny lichen with round soralia in the centre of the yellow-green thallus. Parmeliopsis ambigua is an acidophilous lichen that grows on both bark and wood of coniferous and deciduous wooden plants. It prefers open habitats, especially common it is on wood of stumps, snags and logs in forest clearings and on tree bases that are covered by snow in winter. Less often, it may be found on acidic siliceous stones and rocks in rather moist microhabitats. In Europe, it is an abundant lichen. The centre of its distribution is in boreal mountain areas. In the Czech Republic, the species occurs from lowlands to mountains, but it is significantly more frequent in submountain and mountain areas.
