A relatively variable, usually fertile lichen, characterized by the delimited to merging yellowish soralia on a light grey thallus. The main secondary metabolites are xanthones (especially arthothelin), atranorin is usually contained as well.
Lecidella scabra is primarily a saxicolous species of basic silicates. Furthermore, it is often found on serpentinites and may be seen also on tree bark or wood, usually in dusty places. Here, its distinction from L. flavosorediata may be problematic. In Europe, it is a widespread, but sparsely occurring lichen, as well as in the Czech Republic, where it occurs at lower and middle elevations.taxonomic classification:
