In Czech lichenological literature, countless records of this taxon can be found from the Czech territory. Under the current concept, however, the great majority of them refer to C. efflorescens, C. pulchella and C. rubrisoli, which are collectively treated as C. efflorescens agg. True C. reflexa is characterized by large areoles (up to 0.6 mm), sometimes forming rosette-like thalli, large soredia (40–70 μm), and large biatorine apothecia 0.3–1.3 mm in diameter (though these are formed only rarely). Thallus colour is variable but is often more greenish compared to other sorediate species.
Candelariella reflexa grows on bark with higher pH (elms, ashes, pears, etc.), which is often overgrown by bryophytes. However, it is not a typical component of strongly nitrophilous communities, unlike, for example, C. efflorescens. It prefers well-lit habitats such as tree avenues, parks, or open woodlands. In the Czech Republic it is rare, known from fewer than ten localities. In Europe it is widely distributed.
