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 uncommon lichen. Most of its localities are known from central Europe. In the Czech Republic, it is known mainly from central and southern Bohemia. However, new records have been accumulating rather quickly in recent years.
