A conspicuous and rather easily recognizable lichen, characterized by the yellow-green leprose thallus. Apothecia are often missing. It might be confused with the sulphur-yellow thalli of Chrysothrix chlorina with which it often co-occurs on vertical to overhanging siliceous rocks and stones. P. lucida is abundant from lowlands to mountains, both in central Europe and the Czech Republic. It prefers acidic substrates but is also common on mineral-enriched rocks. It might also occur on dry acidic bark of trees, especially coniferous.taxonomic classification:
