A sorediate crust, which resembles the pale forms of Lecanora expallens. However, it differs in secondary metabolites – L. albida produces atranorin, thiophanic acid, capistratone and arthothelin. Apothecia are present only rarely.
The species grows on a variety of deciduous wooden plants, but it has been reported also from bark of conifers (Dietrich 2007). It prefers light, both forest and non-forest habitats at lower to submontane elevations. In the Czech Republic, it occurs, for example, in thermophilous oak forests in river valleys. Lecidella albida is a less known and probably rare lichen. Most of its localities are known from central Europe. In the Czech Republic, the species has been reported only from a couple of sites.
