A very conspicuous lichen with an extensive attention-attracting bright yellow thallus covering shady rocks. It occurs in a company of various Lepraria species and a similar but yellow-green Psilolechia lucida. Chrysothrix chlorina is one of the typical rain-avoiding saxicolous lichens, therefore it usually grows on overhanging or vertical siliceous and volcanic rocks. Less often it may be found also on a tree bark. It is common in sandstone rock towns or in river canyons. In Europe and in the Czech Republic, it is a widespread, locally common species.taxonomic classification:
