Catillaria atomarioides (Müll. Arg.) H. Kilias

An inconspicuous lichen with very small black apothecia (up to 0.2 mm in diam.). From the similar C. chalybeia, it differs in apothecium size and hyaline hypothecium. It grows on hard siliceous rocks, often enriched with minerals (e.g., on serpentinite) from lowlands to mountains. It may also occur on anthropogenic substrates. C. atomarioides prefers species-poor habitats. It is widely distributed in Europe, from southern boreal belt to the Mediterranean with oceanic tendencies. In the Czech Republic, it was first published from serpentinite in the Slavkovský les (Slavkov Forest) highlands (Peksa 2011) and has been found at a few more localities since (the Křivoklát, Middle Vltava and Třebíč regions). It will probably be found elsewhere, too.
