Candelaria concolor (Dicks.) Stein

A yellow lichen with a little citrine-yellow, rosette-like thallus and thin white rhizines. Sometimes, the thallus is subtle and squamulose, then the species may resemble the recently described C. pacifica. These two species were not distinguished in the past and all the findings were reported as C. concolor. Besides the morphological traits, minor differences may be seen also in the species' ecology. Candelaria concolor occurs relatively often on mossy tree trunks and less often on basic mossy rocks. Alike C. pacifica, it grows also on nutrient-rich bark of deciduous trees in an open landscape (such as parks and avenues). It is a widespread lichen in Europe, but rather scattered and locally common. Recent reports from the Czech Republic are relatively infrequent. Especially in the northern part of the country, the lichen is currently very rare, probably in a consequence of the strong air pollution in the past century.
