Acarospora moenium (Vain.) Räsänen

The inconspicuous areoles of A. moenium are small and white and have black soralia. It is the only known sorediate member of the Acarosporaceae. The species grows on walls and buildings, especially on concrete, and in nature on calcareous or calciferous rock. It often grows in moist situations in shade or full sun in Europe and North America. It is easy overlooked and under-collected but is probably common in central Europe. In the Czech Republic, A. moenium is widely distributed from lowlands to mountains but quite rarely reported. Its highest known elevation in the country is 1385 m in Krkonoše.
