Flavoparmelia caperata is a large lichen, characteristic by its yellow-green colour, verrucose soralia and the content of caperatic and protocetraric acids. It grows on acidic bark of deciduous trees, mainly oaks, and on mossy siliceous rocks in open habitats and well-lit forests from low to middle elevations. It is a species relatively sensitive to air pollution, therefore it had noticeably declined in the second half of the 20th century in the Czech Republic. However, large populations survived in some river valleys (the Vltava, Berounka and Dyje rivers), where its ecological optimum is probably met. In consequence of improved air quality, the lichen has been slowly recolonising the country during the past two decades. Nowadays, it is again relatively common in lower elevations. Besides its typical habitat, it can be often found in larch plantations and in on Prunus spinosa and Crataegus sp. twigs.taxonomic classification:
