Toniniopsis aromatica (Sm.) Kistenich, Timdal, Bendiksby & S. Ekman

A variable lichen with a light grey to brown squamulose thallus, often pruinose and with black lecideine apothecia. It grows on calcareous soil and rock substrates (incl. anthropogenic ones) from the lowlands to the mountains. It is initially parasitic on various crustose lichens (often on cyanolichens). Its centre of distribution lies in Europe, where T. aromatica represents one of the most common species of Toninia sensu lato (Timdal 1992). Interestingly, it is rare in the Czech Republic. Recently, the species has only been recorded in Týřov in the Křivoklát region. It probably was not common in the past either (see individual records in the Vězda & Liška 1999 catalogue).
