Scytinium tenuissimum (Hoffm.) Otálora, P.M. Jørg. & Wedin

Scytinium tenuissiumum is a minute grey-brown cyanolichen with a squamulose thallus, usually sterile. It is recognizable by deeply dissected margins. It grows on acidic to basic soil in open forests, rocky steppes and various anthropogenic stands (e.g., heap piles or sludge ponds). In the Czech Republic, the lichen is mostly found on natural stands in Český kras (the Czech karst), Middle Vltava region, Křivoklát region, and on serpentines near Želivka, Mohelno and Raškov. From anthropogenic substrates, it is known on heap piles near Kladno and also from some villages and towns.
