Candelariella reflexa (Nyl.) Lettau

A number of reports on the occurrence of this species may be found in the Czech lichenological literature. However, according to the current knowledge, most of them refer to * C. efflorescens* and C. xanthostigmoides, i.e. * C. efflorescens* agg. The proper C. reflexa differs in the tiny rosette thallus with well-developed lobes, eventually forming only large sorediate squamules. Soredia are produced on the lobe surface and do not form a continuous crust as in C. efflorescens agg.

Candelariella reflexa grows on tree bark with higher pH (such as elms, ash and pear trees), often overgrown by bryophytes. Unlike taxa from the C. efflorescens agg., C. reflexa is not a typical member of nitrophilous communities. The species is rare in the Czech Republic, so far known only from a few localities in the Pálava region, the Moravský kras karst region and the Javorníky Mts. European distribution of the species is not sufficiently known yet.
