Micarea subviridescens (Nyl.) Hedl.

Usually sterile lichen from the Micarea prasina group that remotely resembles members of the genus Lepraria but is markedly dark-blueish. In contrast to other related species, M. subviridescens often occurs also on inorganic substrates. It usually grows on mineral soil, hummus and detritus in fissures of shaded acidic rocks or directly on the rock. It may even pass onto dying bryophytes and protruding dry shaded roots. The lichen is safely identifiable thanks to the content of prasinic acid, specific for this species. In the Czech Republic, it is known to occur in the Šumava Mts and their foothills, the Blanský les Mts, Kokořín region and on serpentinites around the Želivka river.
